You can use Cursor like that   USE master GO  DECLARE  SQL AS VARCHAR 255  DECLARE  SPID AS SMALLINT DECLARE  Database AS VARCHAR 500  SET  Database    AdventureWorks2016CTP3   DECLARE Murderer CURSOR FOR SELECT spid FROM sys sysprocesses WHERE DB NAME dbid     Database  OPEN Murderer  FETCH NEXT FROM Murderer INTO  SPID WHILE   FETCH STATUS   0      BEGIN     SET  SQL    Kill     CAST  SPID AS VARCHAR 10             EXEC   SQL      PRINT    Process     CAST  SPID AS VARCHAR 10      has been killed      FETCH NEXT FROM Murderer INTO  SPID     END   CLOSE Murderer DEALLOCATE Murderer   I wrote about that in my blog here  http   www pigeonsql com single-post 2016 12 13 Kill-all-connections-on-DB-by-Cursor
