160、【SOQL – GROUP BY ROLLUP (fieldName)】:

SELECT Stagename, COUNT(Id) Records FROM Opportunity GROUP BY ROLLUP (Stagename)

Using GROUP BY ROLLUP in a query makes it easy to get the necessary statistics to evaluate the selectivity of various conditions.

salesforce的功能_salesforce开发

SELECT WEEK_IN_YEAR(CloseDate), CALENDAR_YEAR(CloseDate), COUNT(id)
FROM Opportunity
GROUP BY ROLLUP(WEEK_IN_YEAR(CloseDate),CALENDAR_YEAR(CloseDate))
ORDER BY CALENDAR_YEAR(CloseDate), WEEK_IN_YEAR(CloseDate)

The query returns statistics about the distribution of Opportunity records across every week of every year by CloseDate

158、【MALFORMED_QUERY – Result size: [n>1]】:Known issues

问题:当使用Tooling API查询Remote Site Settings的Name时报错 – MALFORMED_QUERY: When retrieving results with Metadata or FullName fields, the query qualificatio​ns must specify no more than one row for retrieval. Result size: 2

salesforce的功能_salesforce开发

解决方案:        

Query this field only if the query result contains no more than one record. Otherwise, an error is returned.
If more than one record exists, use multiple queries to retrieve the records. This limit protects performance.

// Get all the IDs
SELECT Id FROM Layout WHERE TableEnumOrId IN (Contact, Opportunity, Quote) ORDER BY Name

// Do this for each id
SELECT FullName, Metadata, Name, TableEnumOrId FROM Layout WHERE id = ‘Some_id’

以下两种方案都ok:此SF限制出于性能考虑

// 包含Fullname则需要使用Limit 1
SELECT Fullname, IsActive, Description FROM RemoteSiteSetting LIMIT 1

// 不包含Fullname无需限制
SELECT Id, IsActive, Description FROM RemoteSiteSetting

// 折中办法
查询所有id,然后再便利id list指定id参数查询含Fullname的数据

156、【查询Activity (Task / Event)的WhatType和WhoType】:

背景介绍:在做SFDC前后端分离项目时,需要将Who.Type和What.Type返回给前端,下面将要探讨的是在使用SOQL Polymorphism的前提下,如何做到这一点?

不妨先看下图错误提示:在SELECT语句里面SOQL Polymorphism和Who.Type无法共存

salesforce的功能_salesforce开发

Who.Type方案:但由于WhoId有且只关联Lead / Contact 2个对象,不妨通过创建WhoType__c公式字段,再利用SOQL Polymorphism来展示type

What.Type的获取和Who.Type在SOQL的写法上稍微有点不同,如下图中我们可以直接在typeof中包含type字段,但是黄圈标记的部分乍一看会很奇怪,为啥type是Client,而不是Opportunity呢?

salesforce的功能_salesforce开发

原来Account和Opportunity上都有Type标准字段,如果记录中这个Picklist有值,则显示实际值,否则显示合理的类型

What.Type方案:对于包含标准Type字段的标准对象,我们不妨像Who.Type样新建公式字段WhatType__c,这样就能正确获取对象类型

154、【在User Interface启用Custom Object Truncate】:Truncating Custom Objects | Manage Deleted Custom Objects

对于Admin而言,SF提供了Mass Delete标准对象功能,如果需要mass hard delete诸如BatchJobLog / Integration Log等自定义对象数据,可以考虑此功能。

You can’t truncate standard objects or custom objects that:

  • Are referenced by another object through a lookup field or that are on the master side of a master-detail relationship
  • Are referenced in a reporting snapshot
  • Have a custom index or an external ID
  • Have activated skinny tables

Truncating a custom object erases:

  • All records currently sitting in the custom object’s Recycle Bin
  • The custom object’s history
  • Related events, tasks, notes, and attachments for each deleted record

137、【v50.0及以上版本Apex中的安全导航符?.用例】:How to Use Safe Navigation Operator (?.) in Salesforce Apex | Winter 21 Release Notes

作为Salesforce Winter 21发行版的一部分,salesforce引入了安全导航操作符(?.)来避免Apex中的空指针异常。这对于开发人员而言非常有用。如果我们需要检查某些内容(是否为对象,
map,list ..)不应为null,然后在末尾写(?.)。如果expression(?.)的左侧为null,则不评估右侧,结果将为null。

// #1 示例1
if (object!= null){
    String s = object.fieldName;
}

// 使用v50.0及以上api版本,可改写为
String s = object?.fieldName;

// #2 示例2
String accountName;
if(accountIdAccountMap <> null && accountIdAccountMap.get(accId) <> null)
    accountName = accountIdAccountMap.get(accId).Name;

// 使用v50.0及以上api版本,可改写为
String accountName = accountIdAccountMap?.get(accId)?.Name;

135、【SOQL中的FIELDS功能】:SP21 DE Registration | SP21 Release Notes | FIELDS()

salesforce的功能_salesforce开发

Bounded and Unbounded Queries

The API distinguishes bounded queries, which have well-defined sets of fields, from unbounded queries, which have sets of fields that the API can’t determine in advance. For example, because the number of custom fields for an object is not predetermined, FIELDS(CUSTOM) and FIELDS(ALL) are considered unbounded. This table shows the support for FIELDS() in bounded and unbounded queries:

Bounded – FIELDS(STANDARD) Unbounded – FIELDS(ALL) and FIELDS(CUSTOM)
Apex (inline and dynamic) Supported Not supported
Bulk API 2.0 Supported Not supported
CLI Supported Supported only if the result rows are limited. See Limiting Result Rows.
SOAP API and REST API Supported Supported only if the result rows are limited. See Limiting Result Rows.

133、【SF15位ID VS 18位ID】:15 or 18 Character IDs in Salesforce.com | 详解 Salesforce 15 和 18 位的 Record IDs

Salesforce.com IDs are case-sensitive so if you wanted to export data to Excel to be used as a lookup table using the VLOOKUP formula, you’ll need to be aware of this. If you happened to have records with IDs of 001A0000006Vm9r and 001A0000006VM9r the VLOOKUP formula, not being “case-aware”, would always find the first record, regardless of the case of the lookup value. Salesforce.com realized the potential problem with this and instigated the 18-character ID.

for(integer i = 0; i < 5; i ++){
    Task newTask = new Task();
    newTask.Subject='Automated Task';
    newTask.OwnerId = ;
    myTasks.add(newTask);
}
Database.DMLOptions notifyOption = new Database.DMLOptions();
notifyOption.EmailHeader.triggerUserEmail = true;

//we need to use the Database.insert() with the DMLOptions to insert the task instead of using the standard insert DML command
Database.insert(myTasks, notifyOption);

使用经验:如果套用上述方法创建Task后没收到Email,可能是Task的Statuis设定为:Complete了。因此,请务必确保Task在Open Activities非Activity History栏,这时该Owner才能收到通知。另外,Email中发件人视环境而定(Internal -> 代码上次修改人;Community -> Community Administration中的Email),Email Body包含Task标准字段信息:Subject,WhoId,Priority,Comments等标准字段信息,若Comments没值,不会显示。

99、【Using Attachment to Storage Logs – Attachment的存与取】:
Case:在做数据集成(类似Data Backup那种)时,非增量的同步往往会超出callout限制,如异步body size限制12MB,同步6MB,这个时候同步到第三方由于数据不合规被skip掉的也不少,之前在没有确定竟然是全量同步的情况下,本身使用自定义对象来存储log,后面skip掉的那些log直接将长文本13w+个字符限制都给超了,无奈在同事的建议下放弃了加字段来分开存储的可能,直接上了Attachment来存,这个可能是Best Practice。
Sample
加入存储的exception log长下面这样:

15 Listing(s) Skipped - {"a060k000005XppaAAC":["Listing's [E&V ID] doesn't start with 'EVHK': 是的發生分散","Listing's [Description] invalid content length: For description at least 30 words and maximum 2500 words"],"a060k000005fAKjAAM":["Listing's [E&V ID] doesn't start with 'EVHK': 435325","Listing's [Property Type](Complexd) doesn't match the property type those set in Squarefoot: Apartment公寓, Stand-alone building 單橦式大廈, Estate 屋苑, Public / HOS flat 公共屋邨 /居屋, Village house 村屋, House / Villa 獨立屋 / 洋房 / 別墅, Car park 停車場, Boat遊艇 / 船.","Listing's [Description] is missing"],"a060k000005YYwoAAG":["Listing's [E&V ID] doesn't start with 'EVHK': sdfsfsf","Listing's [Property Type](Complexd) doesn't match the property type those set in Squarefoot: Apartment公寓, Stand-alone building 單橦式大廈, Estate 屋苑, Public / HOS flat 公共屋邨 /居屋, Village house 村屋, House / Villa 獨立屋 / 洋房 / 別墅, Car park 停車場, Boat遊艇 / 船.","Listing's [Description] is missing"],"a060k000005fC7cAAE":["Listing's [Property Type] is missing","Listing's [Description] is missing"],"a060k000005LopTAAS":["Listing's [E&V ID] doesn't start with 'EVHK': 33252","Listing's [Property Type] is missing","Listing's [Description] is missing"],"a060k000005fBtQAAU":["Listing's [E&V ID] doesn't start with 'EVHK': 34534","Listing's [Description] is missing"],"a060k000005MCLfAAO":["Listing's [Description] is missing"],"a060k000005fDTzAAM":["Listing's [E&V ID] doesn't start with 'EVHK': 324566","Listing's [Description] is missing"],"a060k000005eWhPAAU":["Listing's [E&V ID] doesn't start with 'EVHK': 23552352435235","Listing's [Property Type] is missing","Listing's [Description] invalid content length: For description at least 30 words and maximum 2500 words"],"a060k000005f9spAAA":["Listing's [E&V ID] doesn't start with 'EVHK': 1233321","Listing's [Description] is missing"],"a060k000005fBtaAAE":["Listing's [E&V ID] doesn't start with 'EVHK': 4333228","Listing's [Description] is missing"],"a060k000005dAThAAM":["Listing's [Property Type](Complexd) doesn't match the property type those set in Squarefoot: Apartment公寓, Stand-alone building 單橦式大廈, Estate 屋苑, Public / HOS flat 公共屋邨 /居屋, Village house 村屋, House / Villa 獨立屋 / 洋房 / 別墅, Car park 停車場, Boat遊艇 / 船.","Listing's [Description] invalid content length: For description at least 30 words and maximum 2500 words"],"a060k000005XpjEAAS":["Listing's [E&V ID] doesn't start with 'EVHK': ewetw","Listing's [Description] is missing"],"a060k000005fAQhAAM":["Listing's [E&V ID] doesn't start with 'EVHK': 23423","Listing's [Description] is missing"],"a060k000005cmyGAAQ":["Listing's [Property Type] is missing","Listing's [Description] is missing"]}

关于存:那么我们使用Attachment存只需要使用下面几个关键字段:Name/ParentId/Body(blob)。

List<Integration_Log__c> logs = [SELECT Id, Excepition__c  FROM Integration_Log__c WHERE Id = 'a080k00000DPLgG' LIMIT 1];
System.debug(logs[0].Excepition__c.length());
String content  = logs[0].Excepition__c;
Attachment att = new Attachment();
att.Parentid = 'a080k00000DPLgG';
att.Name = 'SfdcSyncListingsTosquarefoot partial success!';
att.Body = blob.valueOf(content);
insert att;

关于取:我们将Blob使用Blob.toString()转以下就好了。

List<Attachment> atts = [SELECT Id, ParentId, Name, ContentType, Body, Description FROM Attachment WHERE Id = '00P0k000002yNQm'];
Blob contentBlob = atts[0].Body;
String str = contentBlob.toString();
System.debug(str);

94、【Email-to-Case那点坑】:
在做如下需求时:

email 2 case

TARGET:
do search in both contact and lead and populate the lead or contact value on case.

LOGIC:
1. email match sigle client -> relate to client
2. email match sigle lead   -> relate to lead
3. email match more than one lead or client or <both 1 lead + 1 contact> -> not relate
4. no match lead or contact -> no relate

RECORDTYPE:
case      -> Enquiry Case Record Type
contact   -> all<contact + personal contact>

Note:
SuppliedEmail on case will be the end client's email;
End clients will send email to the service email not the real email when using email to case;

Trigger Logic Design:
1. before insert

遇到了一个坑,当单个Lead和单个Contact的Email都相同时,根据上述逻辑3, 理应Account/Contact值不应被填充,发现神奇的被填充上了,当时检查了原有的所有apex code和workflow/flow/process builder,都没发现有这个逻辑,最后在同事Don的帮助下,最终解决了这个问题。

原因sf标准的Email-to-Case,如果有一个Contact Email匹配上了邮件发送人的Email,就会自动填充Account和Contact;如果有多个Contact都含有相同的Email,那么就不填充。所以上述逻辑中尽管单个Lead和单个Contact的Email都相同,但是由于Contact为单个的缘故,执行了标准功能的自动填充。

解决方案:在before insert trigger的else语句中清空Account和Contact即可。

93、【使用count()计数统计记录】:
我们在使用SOQL时,用的最多的是select count() from sObject,这种形式默认是根据记录Id来进行聚合统计,那假如我们使用count(field api name),我们就能够统计某字段值不重复的所有记录数了,如下是我们统计系统中Lead的Phone唯一的记录数的code snippets:

SELECT count(Phone) FROM Lead

75、【Dynamic SOQL特别注意事项】:
a、Dynamic SOQL with an IN Clause and map.KeySet()

MAP<ID,Opportunity> os = new MAP<Id,Opportunity>([Select ID from Opportunity]);
SET<ID> keys = os.keyset();// 此处必须转一下,不能直接在soql里面使用
String s = 'SELECT  RecordTypeId, COUNT(Id) os FROM Opportunity Where Id IN ';
s+=':keys GROUP BY RecordTypeId';
AggregateResult[] ars = Database.query(s);
System.debug(ars[0].get('RecordTypeId'));

b、实战Sample1

Set<Id> recordIdSet = new Set<Id>();
switch on sobjectType {
	when 'lead'    {recordIdSet = leadIdSet;}
	when 'contact' {recordIdSet = contIdSet;}
}

String queryStr = 'select id, email from ' + sobjectType + ' where id in :recordIdSet';
List<Sobject> sobjList = Database.query(queryStr);

c、实战Sample2

Boolean isConfig = 'config__c'.equals(sobj.toLowerCase());
String queryStr = (isConfig ? 'SELECT Value__c n' : 'SELECT Name n') + ' FROM ' + sobj + ' WHERE Id = \'' + recId + '\' GROUP BY ' + (isConfig ? 'Value__c' : 'Name');

// Note: 部分時候會出現使用'Id = '\' + recId + '\'過濾未生效,需要變更成:'Id = :recId';

NOTEdynamic SOQL cannot use bind variable fields in the query string. It will yield ‘variable does not exist‘ error. However, it can be used in regular assignment statements.

	String queryStr = (isConfig ? 'SELECT Value__c n' : 'SELECT Name n') + ' FROM ' + sobj + ' WHERE Id = \'' + recId + '\' GROUP BY ' + (isConfig ? 'Value__c' : 'Name');
	System.debug('queryStr: ' + queryStr);
	return String.valueOf(Database.query(queryStr)[0].get('n'));
}

优化:

// 根据Id获取相关Name值 - 用于字段历史跟踪转义
// 注意:由于Listing Name为自动编号,所以不可Group
public static String getConvertedNameById(Id recId) {
    String sobj = String.valueOf(recId.getsobjecttype());

Standard Object:为SobjectId;
Custom Object:  为ParentId;

String suffix = 'History';

Id recId = (Id)parmmap.get('recordid');
String sobj = String.valueOf(recId.getsobjecttype());//根据记录id获取对象api name
Boolean isCustomObj = sobj.contains('__c');

System.debug('recId\'s sobject type is: ' + sobj);

String sobjectHistory = (isCustomObj ? sobj.left(sobj.length() - 1) : sobj) + suffix;
String parentType = isCustomObj ? 'ParentId' : (sobj + 'Id');

System.debug('sobjectHistory: ' + sobjectHistory);
System.debug('parentType: ' + parentType);

List<sobject> histories = Database.query('SELECT Id, IsDeleted, ' + parentType + ', CreatedById, CreatedDate, Field, OldValue, NewValue FROM ' + sobjectHistory + ' WHERE ' + parentType + ' = \'' + recId + '\' ORDER BY CreatedDate');

61、【Inspecting Code Coverage】:
Salesforce提供了两种查询方式检索Unit Test覆盖情况:ApexCodeCoverageAggregate/ApexCodeCoverage,使用该对象查询需要启用Use Tooling API,查询模板如下:

SELECT ApexClassOrTrigger.Name, NumLinesCovered, NumLinesUncovered 
FROM ApexCodeCoverageAggregate 
WHERE ApexClassOrTrigger.Name = 'TaskUtil'
SELECT ApexTestClass.Name,TestMethodName,NumLinesCovered,NumLinesUncovered 
FROM ApexCodeCoverage 
WHERE ApexClassOrTrigger.Name = 'TaskUtil'

最近在做CIL(Custom Interaction Log)时发现如下问题:将System.Now()/DateTime.Now()赋值给<apex:inputField type=”Text”/>和<apex:inputField type=”DateTime”/>时,时间不一致,相差8h
salesforce的功能_salesforce开发
Solution: 使用format()转一下时间后,再赋值给Text文本即可解决。
Exp: ‘Last save at ‘ + DateTime.now().format();
总结:用纯文本接收时间就会按照格林威治时间显示,需要使用format()转化,才会显示Local时间

56、当启用个人客户后,创建一条account就copy了份account给contact,其中不管两边哪一边有字段值变动,两边都会同步。Exp:contact有字段isActive,如果更新这个字段为true,那么account记录上的该字段跟着变为true。
启发:更新Account可能会触发Contact的Trigger,反之亦然。

49、【使用soql查询记录条数】
select count() from DTT__Geographic_Region__c

48、使用Salesforce Inspector导出数据并导入到新环境 – 若存在junction对象的数据导入,则需要mapping关系字段,查询时可通过关系查询查Name。
Example】:导入PriceBookEntry数据到UAT – 先导入PriceBook和PriceBookEntry中需要的Product,后导入PriceBookEntry,之后copy csv数据时,该数据的关系字段查询不要使用Id(Product2Id,Pricebook2Id),而选择查对应的Name,后面导入时,再针对Name做Mapping。
【Note】:导入非标准价格手册的PriceBookEntry前,需要先导入标准的PriceBookEntry,只需Care5个字段:CurrencyIsoCode、Product2Id、Pricebook2Id、UnitPrice、isActive。
Addition】:用inspector导地理区域(自己lookup自己)时,ExternalId是关系的核心,可先将省份单独导入后,再导入其他的数据,如果后续导入报错,再拆开单独导入可以避免意料之外的错误。不要忘录关系字段值
salesforce的功能_salesforce开发

48、使用Mavensmate同步DEV与UAT环境中简档的字段级别权限:在环境迁移时,部分元数据会存在丢失,导致两环境存在差异,比如简档中档FLS。
Step by Step】:先登陆到DEV环境,利用Mavensmate retrieve Profile和Custom Object(标准对象也在里面),然后勾选某对象如Order的fields和简档明细,点击Update后,在Sublime中打开文件;使用同样档方法将UAT相关文件下载到本地,然后直接复制粘贴简档文件档元数据覆盖UAT即可。

44、启用或禁用内联编辑 – 有时候我们希望禁用用户默认的行内编辑功能,直接去user interface中将Enable Inline Editing关掉即可。

43、去重Sample – 看似怪诞,实则大有用处:

Map<String, String> accIDs = new Map<String,String>();
for(Quote qt: (List<Quote>)Trigger.New){
    if(!accIDs.containsKey(qt.Quote_To_Account__c))
        accIDs.put(qt.Quote_To_Account__c,'');
}
Map<String, Account> accs = new Map<String, Account>([SELECT id,BillingStreet,BillingCity, BillingState, BillingPostalCode, BillingCountry FROM Account WHERE Id IN : accIDs.keySet()]);

42、System.debug(‘result: ‘ + rtMap.get(myRt).equals(qt.RecordTypeId) + ‘–qt.RecordTypeId: ‘ + qt.RecordTypeId + ‘–rtMap.get(myRt): ‘ + rtMap.get(myRt));Id为18位。

41、Opportunity和Quote为Master-Detail关系,在导入历史数据时,Opportunity和Quote的Owner未同步,事后同步时,不可使用apex方法更新Quote Owner,错误信息为:”Can’t change quote owner. Enable quotes without parent opportunities.”。

40、如果记录锁定,用户需要更新记录,则必须使用Webservice,比如:报价锁定非系统管理员需自动同步报价时,我们需要在Trigger里面调用Webservice,这时就需要使用到@future异步方式了。

39、Lead Home Page调整经验之谈

a、没有配置方法实现Home页面布局调整,比如将Tools和Reports换个位置;

b、无法用自定义报表链接替换Reports里面的标准报表链接-无法编辑标准报表,无法将自定义报表移至Lead Reports Folder;

c、如果必须实现只能重写标准Lead Tab按钮;

38、Salesforce布局特性:如果相关列表上无任何按钮,那么相关列表面板只有在有记录时才会显示

37、Salesforce获取某个日期所在月份的天数

Date d = System.today();
Integer numberDays = date.daysInMonth(d.Year(), d.Month());
System.debug(numberDays);

36、在为输入元素赋初始值时,我们经常会使用url将参数写入该输入元素的Name属性,我们通常会担心,在Org迁移时,这些Name值是不是会改变,从而增加我们的维护负担?经调研,Vf画面的Name不会随着Org的改变而改变

35、使用apex获取IP地址ApexPages.currentPage().getHeaders().get(‘X-Salesforce-SIP’);

34、封装Map<String, List<Sobject>>技巧 + 去重 | 参考资源:How to Send More than 10 E-mails

Map<Id, List<Case>> userCaseMap = new Map<Id, List<Case>>();
List<Case> allCaseLoggedToday = new List<Case>();
List<Id> salesIds = new List<Id>();
List<User> salesRep = [SELECT Id , Name , Email , ManagerId 
                       FROM User 
                       WHERE Profile.Name = 'System Administrator'];
for(User u : salesRep) {
  salesIds.add(u.Id);  
}
allCaseLoggedToday = [SELECT Id, CaseNumber,CreatedById, Owner.Name , Account.Name , Contact.Name  
                      FROM Case 
                      WHERE CreatedDate = TODAY AND CreatedById in : salesIds];
for(Case c : allCaseLoggedToday) {
  if(userCaseMap.containsKey(c.CreatedById)) {
    //Fetch the list of case and add the new case in it
    List<Case> tempList = userCaseMap.get(c.CreatedById);
    tempList.add(c);
    //Putting the refreshed case list in map
    userCaseMap.put(c.CreatedById , tempList);
  }else {
    //Creating a list of case and outting it in map
    userCaseMap.put(c.CreatedById , new List<Case>{c});
  }
}

33、salesforce soql中不能对公式字段使用Group By;

32、Partner User对Quote Tab不可见,Quote无Sharing Rule,它的共享受Opportunity的控制,如果对Partner User的Quote的OLS设置为View且Opportunity页面布局的Quote放出来了,如果共享Opp的Owner没有创建Quote记录,Partner User不可见Quote相关列表,需要创建一条Quote,才可以看见。

31、Apex中List、Map、Set集合总结:
List:有序、可重复;
Map:无序,key重复则value覆盖;
Set:无序,不可重复;即使重复了,取前面的值,如:

Set<Integer> s = new Set<Integer> {1,2,3,2,1};
system.debug('s: ' + s);

DEBUG INFO:s: {1,2,3}
Sample:

List<Account> accs = [select id, name from account limit 3];
map<Id, Account> m = new map<Id, Account>();
String lastId = '';
if(accs != null && !accs.isEmpty()) {
    Integer i = 0;
    for(Account a : accs) {
        System.debug('a['+i+'] : ' + a);
        lastId = a.Id;
        m.put(a.Id, a);
        i++;
    }
}
// 验证List有顺序,Map无顺序
System.debug(m);
System.debug(m.get(lastId));
Map<String, String> m1 = new Map<String, String> {
    'key1' => 'value1',
    'key2' => 'value2',
    'key1' => 'value2',
    'key2' => 'value3',  
    'key1' => 'value3'
};
System.debug('m1: ' +m1);
System.debug('m1.key1: ' + m1.get('key1'));

30、创建Task:

任务:
Task task = new Task();
task.Subject = ‘A信息修改申请';
task.status = 'open';
task.priority = 'High';
task.whatId = '0017F00000CfcdsQAB';// 相关项目,这里是供应商Id
task.ownerId = '0057F000000pe6uQAA';// 被分配人,这里是UserId
// 以下两行是设置提醒
task.IsReminderSet = true;
task.ReminderDateTime = System.now();
insert task;

29、根据自定义地理定位数据类型字段API名表示经纬度

现有API名称为:Geographic_Coordinates__c的地理位置坐标字段,要表示经度使用:Geographic_Coordinates__Longitude__s, 要表示纬度使用:Geographic_Coordinates__Latitude__s

Select Id, Address__c, Geographic_Coordinates__Longitude__s, Geographic_Coordinates__Latitude__s From Store__c

28、Live Agent配置:step by step resource

1、先启用live agent – setup -> live agent settings -> enable

2My Settings -> Advanced settings -> Live Agent User(勾选上)

27、使用Database.query()查询数据集合:

filterStr = 'AND Type__c = \'Text\' ';// 注意写成转义字符形式
query = 'SELECT Name, Type__c, Message__c, Msgpic__c, Mediaid__c, VioceRecognition__c, VoiceFormat__c, VoiceSrc__c ' + 
        'FROM BD_CaseDetail__c ' + 
        'WHERE Case__c = :caseId ' + filterStr + 'ORDER BY CreatedDate ASC LIMIT 500';
caseDetailList = Database.query(query);
caseDetailList = [SELECT Name, Type__c, Message__c, Msgpic__c, Mediaid__c, VioceRecognition__c, VoiceFormat__c, VoiceSrc__c
                  FROM BD_CaseDetail__c
                  WHERE Case__c = :caseId AND Type__c = 'Text' ORDER BY CreatedDate ASC LIMIT 500];

26、Apex实例化一个内部类:

public class OuterClass {
    public class InnerClass {
        String name = '';
        Blob body = '';
    }
}
// 实例化内部类
OuterClass outer = new OuterClass();
OuterClass.InnerClass inner = new OuterClass.InnerClass();
/*接口类实例化*/
global class SyncInterface {    
    // 封装数据结构 - 返回结果  
    global class SyncResults{  
        global List<Response> responses;  
    }  
      
    global class Response{  
        public String TYPE;  
        public String MSG;  
        public String BUSINESS_ID;  
        public String SALESFORCE_ID;  
        public String PROC_TYPE;              
    }  
}

// 实例化接口response list
SyncResults syncResponseList = new SyncResults();  
syncResponseList.responses = new List<Response>();

25、限制点击自定义按钮的简档:

/**

    参数说明:用户Id
    返回值:true/false
    作者:Wilson Xu
    日期:2017-07-26
    **/   
    public static Boolean isValidUser(String userId){
        Set<String> profileSet = new Set<String>{'品牌专员','事件行销专员','物料制作专员','线上媒介专员','线下媒介专员','展览展示专员','子公司企划专员'};
		String profileName = [SELECT Profile.Name FROM User WHERE Id = :userId].Profile.Name;        
        return profileSet.contains(profileName);
    }
// 验证该用户是否为专员简档用户
    	if(!isValidUser(UserInfo.getUserId())){
            result.code = '1';
            result.msg = '只有相关专员才能发起定向谈判!'; 
            return JSON.serialize(result);
        }

24、使用apex处理日期:

a. DateTime in Apex

DateTime nowTime = System.now();
String now_date = nowTime.format('yyyy-MM-dd');
String now_dateTime = nowTime.format('yyyy-MM-dd HH:mm:ss');
System.debug(now_date+'<------>'+now_dateTime);

debug信息:

14:23:00:002 USER_DEBUG [4]|DEBUG|2017-07-26<------>2017-07-26 14:23:00

b. Date in Apex – String to Date | Date Class valueOf(stringDate)

String strDate1 = '2018-6-6';
String strDate2 = '2018-06-06';
String strDate3 = '2018/6/6';
Date myDate1 = date.valueOf(strDate1);
Date myDate2 = date.valueOf(strDate2);
//Date myDate3 = date.valueOf(strDate3);//System.TypeException: Invalid date: 2018/6/6
System.debug('myDate1: ' + myDate1);
System.debug('myDate2: ' + myDate2);
//System.debug('myDate3: ' + myDate3);

20、图解批准进程approval process,理解队列,多级审批:图解salesforce多层级审批&同级多审批者approval process_sf_wilson的博客-CSDN博客
19、pageBlockTable中的column组件设置宽度不生效的解决方案:
a、嵌套关系1: form>pageBlock>pageBlockTable>column,可以直接为column增加width的style或者styleClass,需要的话pageBlockTable设置个width:100%;
b、嵌套关系2: form>pageBlock>pageBlockSection>pageBlockTable>column,这个时候添加style和styleClass是不生效的,此时只需要在pageBlockTable中设置columnsWidth=”width1,width2…”;

18、创建visualforce的4种方法:
a、导航法 – setup->developer->visualforce page;
b、developer console;
c、IDE – eg. sublime text / eclipes – 安装eclipes并配置forceIDE插件视频 – https://www.youtube.com/watch?v=ufe62nGecMg

17、apex:page组件与apex:sectionHeader组件属性的相互影响:
apex:page组件中比较少用到的属性:

<!--
setup="true";show sidebar as setup format;
renderAs="pdf";the body you development will show as pdf;
action="someMethods";excute the action first before render the page;
-->
<apex:sectionHeader title="Section Header Practice" subtitle="Home" description="draw your page using code" help="https://baidu.com" printUrl="https://baidu.com"/>
<span style="color:#ff0000">如果page中用到了setup="true"属性,那么sectionHeader中就不能显示对象图标。</span>

16、在Js中两种方法获取组件id
a、{!$Component.idName} – eg.  var el1 = document.getElementById(‘{!$Component.name}’).value;// 该方法不需要写嵌套的id,若要指明则:$Component.bk.age
b、pg:fm:bk:name – eg. var el2 = document.getElementById(‘pg:fm:bk:name’).value;// 该方法每个组件均需要指明id,并按嵌套关系依次书写,id间以:隔开
当然我们也希望在css中应用id选择器,我们可以:
<style>[id*=ip2]: color: f00;</style>

<apex:page id="pg">
    <apex:form id="fm">
        <apex:inputText id="name" onchange="show()"/>
        <script>
            function show() {
                var el1 = document.getElementById('{!$Component.name}').value;
                var el2 = document.getElementById('{!$Component.bk.age}').value;
                alert('name: '+el1+', age: '+el2);
            }
            function demo() {
                // getting specific dom element by this format, you shold write every level id.
                var el1 = document.getElementById('pg:fm:name').value;
                var el2 = document.getElementById('pg:fm:bk:age').value;
                alert('name: '+el1+', age: '+el2);
            }
        </script>
        <apex:pageBlock id="bk">
            <apex:inputText id="age" onchange="demo()"/>
            <apex:pageBlockSection id="bks1">

                    document.getElementById('pg:fm:bk:bks2:ip2').value = el;
                    document.getElementById('pg:fm:bk:bks2:op').innerHTML = el;
                }
                function al() {
                    alert('Testing...');

15、15位Id与18位Id的区别?

C:Q:: what is the difference 18 digit id and 15digit?

Ans: When we create record in the object salesforce will create 18 digit unique to recognize it.

This is a case insensitive

Same 18 digit is represented as 15 digit id as case sensitive

Id 001—9000001—1o2Of in this 15/18 digit id first 3digits indicate Object and last 5 digits indicate record

===========================排序策略调整<最近的在最前面>==========================

1、使用SOQL语句查询时,字符串类型的只能使用‘单引号’,否则报错:Unknown error parsing query;

eg:SELECT Id, Subject, CaseNumber, Status, Priority 

        FROM Case 

        WHERE CaseNumber = ‘00001036’ //注意此处autoNumber类型数字为String类型

使用SOQL其他注意事项:

a、尽量使用Order By,保证查询结果的稳定性;
b、使用LIMIT,防止数据量超过50000而报错;
c、使用Offset偏移时,一定放在该查询语句的最后面,其限制及应用场景见:Salesforce Developers

2、标准字段的API Name即为该标准字段的Field Name;

eg:Case标准对象的Subject API Name即为 Subject

3、计算两个日期之间相隔的天数:

eg:TODAY() – DATEVALUE( CreatedDate )

        Implementd__Date__c – DATEVALUE( CreatedDate )

注意:只有当日期为标准字段时,才使用DATEVALUE()来转化

4、在terminal中使用curl方式查看json数据(通常使用workbench>utilities>REST Explorer),通常会用到sessionId,获取方法如下:

        return thisCase.Id;
    }
    /*
HttpPatch步骤:
1、创建RestRequest类型的req对象(RestContext.request的返回值类型就是RestRequest)
2、通过req对象的requestURI属性利用字符串检索技术拿到caseId
3、创建Case对象,并把按Id查到的Case表记录赋值给该对象
4、将请求获得的requestBody转化成字符串后,反序列化为对象强制转化为Map<String, Object>后赋值给Map变量params
5、遍历对象的key,并在通过id找到的Case对象thisCase中写入key-value
6、更新记录
7、返回记录的id

}
/*
共性:
1、每个对象系统自带一个Id属性,它是系统自动分配的;
2、每一种Http方法均为global static
3、@HttpPut与@HttpPost的区别(upsert,insert)

区别:put vs patch

the same:You can update records with the put or patch methods.

the difference: put can either create new resouce or update the existing resource; patch can update the existing resouce exclusively.

6、Apex中在使用类继承时需要使用到的关键字:extends,super,virtual,override.跟Java继承不同的是,超类必须使用virtual修饰,子类使用override和extends修饰,如果需要重写父类的方法,父类中该方法需要用virtual修饰,子类需要使用override。另外如果子类需要使用超类的域或者方法则需要使用super关键字,注意构造方法的复用不需要用成对的virtual和override关键字修饰超类的构造方法和子类的构造方法。

7、利用公式字段插入图片:IMAGE(path,img_title,height,width)

8、在report中使用The “Power of One” technique来统计不重复的数据

9、在Apex中使用静态资源加载jquery:

<apex:page>
    
    <!-- Add the static resource to page's <head> -->
    <apex:includeScript value="{! $Resource.jQuery }"/>
    
    <!-- A short bit of jQuery to test it's there -->
    <script type="text/javascript">
        jQuery.noConflict();
        jQuery(document).ready(function() {
            jQuery("#message").html("Hello from jQuery!");
        });
    </script>
    
    <!-- Where the jQuery message will appear -->
    <h1 id="message"></h1>
    
</apex:page>

10、简单的使用vf标准控制器来展示Contact列表,并实现点击名称跳转详细页面。方法有三种:

<apex:page standardController="Contact" recordSetVar="contacts">
	<apex:pageBlock title="Contact List">
		<apex:repeat value="{!contacts}" var="ct">
			<li>
				<apex:outputLink value="/{!ct.Id}">{!ct.Name}</apex:outputLink>
				<!-- <apex:outputLink value="{!URLFOR($Action.Contact.View,ct.id,[retURL=''])}">{!ct.Name}</apex:outputLink> -->
				<!-- <apex:outputLink value="https://componentstest-dev-ed.my.salesforce.com/{!ct.Id}">{!ct.Name}</apex:outputLink>  -->
			</li>
		</apex:repeat> 
	</apex:pageBlock>
</apex:page> 

11、增强lookup查找功能:我们通过lookup进行对父记录Name进行搜索时,通常默认只能使用Name来搜索,有时候比如我们在子记录中想要通过Phone来搜索Account的Name,这个时候可以在setup->enter ‘Search Settings‘ in Quick Search Box中即可增强搜索

12、将使用html编辑的前端网站放到force.com平台上的方法:将做好的网站,比如shangpinhui/Bootstrap所有文件打包成zip上传到salesforce的Static Resources中,比如拿shangpinhui为例,目录结构为:shangpinhui->images/js/css/index.html,打包上传后命名为ShangpinhuiZip(名字不能一数字开头),之后在Visualforce Pages中编辑如下代码:

<apex:page docType="html-5.0" sidebar="false" showHeader="false" standardStylesheets="false" 
      action="{!URLFOR($Resource.ShangpinhuiZip, 'shangpinhui/index.html')}">
</apex:page>

在action里面通过URLFOR表达式来将页面加载进去。这样就不用考虑修改网站页面资源引用的路径了,注意在Developer Edition里面由于每个账号限制只允许放一个网站绑定一个url,所以要实现多个网站同时上传作为作品展示,可以再做一个列表,分别通过超链接映射到相应的网站上,这样就可以将您的所有作品都绑定在一个页面上分别访问。

13、在Company Information中可以查看User Licence的使用次数,如下图:

salesforce的功能_salesforce开发

14、recordSetVar与<apex:variable value=”{!}” var=””/>的适用场景比较:
recordSetVar保存的是SOBject的List,一般会与<apex:pageBlockTable>以及<apex:page>的熟悉standController(即可以传标准对象也可以传自定义对象)连用,常用于输出性质的组件,而对于输入性质的组件,若强行使用需要加[0],这种场景推荐使用<apex:variable>标签,来将比较长的api名称用变量存储。
