Since the data is not yet committed, the select statement is blocked to avoid reading stale data. In MSSQL server, there's a option to provide a nolock hint to the server through the select query. However AFAIK, MySQL doesn't have such a hint. Try doing this: set transaction isolation level READ UNCOMMITTED; | select * from MyEntity where id = 1; See if it works.
