问题 Hi Is their a way to set autocommit to false in spring jdbctemplate. The thing is instead of transaction (where their is rollback option), I want to have query committed at end of transaction. So instead of insert --> commit --> rollback. I want insert --> fail --> (no commit). 回答1: I did not understand your whole question, but I can answer the first part: Is there a way to set autocommit to false in spring jdbctemplate?

How do you set autocommit in an SQL Server session?

In implicit transaction mode, every change you make starts a transactions which you have to commit manually. Maybe an example is clearer. This will write a change to the database: SET IMPLICIT_TRANSACTIONS ON UPDATE MyTable SET MyField = 1 WHERE MyId = 1 COMMIT TRANSACTION This will not write a change to the database: SET IMPLICIT_TRANSACTIONS ON UPDATE MyTable SET MyField = 1 WHERE

问题 I did a big mistake that I updated a table without 'where' clause in MySQL :'( It is auto-committed.

If you have a backup of the database, you can restore the backup and use DBA tools (in MySQL's case, it's mysqlbinlog) to "replay" all data-modifying queries from the logs since the backup back to the database, but skip over the problem query. If you don't have a backup and all
