管理.NET + Salesforce API的事务

Question

I have .NET application that updates Database and Salesforce through API. I need to update multiple Salesforce Objects.

Code look like this

public class Service ....

public void myTransaction(..){
DBConnection dbcon;
SFConnection sfcon;

// DB Begin Transaction

//Update Database tables 
//Update SF Objects 

// DB End Transaction

}

Please help me to get better idea on how to achieve transaction.

Answer 1

I know this is old, but for reference to those who surf on in:

Like LaceySnr hinted, transactions are not properly available (as of 2016) through the API. There are, however, two ways to achieve transaction-like results via the API.

1. by creating a custom REST endpoint in Apex, or
2. by using the AllOrNone header with the API.

REST Endpoint

To create a custom REST endpoint you would create an apex class defined with @RestResource. Within that class you'd define a function decorated with @HttpPost that takes a list of sObjects. Within the function you would set a savepoint.

When this new endpoint is called, if there a catchable error you can rollback on your own. Otherwise, Salesforce, upon successfully completing the function, will auto-commit. In other words, you don't have to explicitly commit the transaction. See this documentation for creating REST endpoints . and developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/langCon_apex_transaction_control.htm for transaction control (I can't post more than 2 links).

example apex:

    @RestResource(urlMapping='/myendpoint/*')
    global with sharing bool class MyFirstRESTController {

       @HttpPost
       global static boolean doSomething(List<sObject> objectsToUpdate) {
           boolean error = false;
           Savepoint sp = Database.setSavepoint();

           //do something

           //oh no! there was an error
           if( error ) {
                Database.rollback(sp);
           }
           return error;
       }
    }

with that example, if you posted to /services/apexrest/myendpoint/doSomething/ with all of your sObjects it should call that function and give you some transactional control (eg convert the objects to JSON and post them). You'll need to use the "Authorization: Bearer sessionId " header on your call to the custom REST endpoint. The sessionId can be the same sessionId retrieved from a SOAP login (in case you use the wdsl to generate a service).

AllOrNone Header

For the AllOrNone header see the documentation for the SOAP API . This header allows you to indicate that if any single record fails at updating, then they all fail. Essentially, if one record fails, the entire transaction is rolled back.
