To prevent this  make sure every BEGIN TRANSACTION has COMMIT  The following will say successful but will leave uncommitted transactions   BEGIN TRANSACTION BEGIN TRANSACTION  lt SQL CODE  COMMIT   Closing query windows with uncommitted transactions will prompt you to commit your transactions  This will generally resolve the Error 1222 message

In the SQL Server Management Studio  to find out details of the active transaction  execute following command  DBCC opentran     You will get the detail of the active transaction  then from the SPID of the active transaction  get the detail about the SPID using following commands  exec sp who2  lt SPID gt  exec sp lock  lt SPID gt    For example  if SPID is 69 then execute the command as  exec sp who2 69 exec sp lock 69   Now   you can kill that process using the following command  KILL 69   I hope this helps

I had these SQL behavior settings enabled on options query execution  ANSI SET IMPLICIT TRANSACTIONS checked  On execution of your query e g create  alter table or stored procedure  you have to COMMIT it   Just type COMMIT and execute it F5
