Introduction to the implicit start of DB2 transactions

This article mainly describes the implicit start of DB2 transactions. We all know that transactions in Oracle and DB2 databases always start implicitly, and these DBMS do not have certain statements used to start transactions. In Microsoft Access, Microsoft SQL Server, MySQL, and PostgreSQL, you can use the BEGIN statement to start transactions explicitly.

SQL: 1999 introduces the START TRANSACTION statement. Because this occurs a long time after the DBMS starts a TRANSACTION using BEGIN, the syntax for extending BEGIN varies with DBMS. MySQL and PostgreSQL support start transaction as the synonym for BEGIN ).

Begin explicitly starts a transaction

In Microsoft Access or Microsoft SQL Server, enter:

 
 

  
  
BEGIN TRANSACTION; 
 
 

Or

In MySQL or PostgreSQL, enter:

 
 

  
  
START TRANSACTION; 
 
 

Commit committing transaction

Input:

 
 

  
  
COMMIT; 
 
 

Rolling back the transaction

Input:

 
 

  
  
ROLLBACK;
