This is a sample of how to delete a large chunk of data in batches. This is to avoid putting to much data into transaction log which can cause long rollback in case of failure. DECLARE @Table1 TABLE ( id int ) DECLARE @Table2 TABLE ( id int ) INSERT INTO @Table1 SELECT 1 UNION SELECT 2 UNION SELECT 3 INSERT INTO @Table2 SELECT 1 UNION SELECT 2 UNION SELECT 4 SELECT * FROM @Table1 DECLARE @BatchSize int SET @BatchSize = 10 WHILE ( Exists ( SELECT 1 FROM @Table1 t1 LEFT JOIN @Table2 t2 ON t1.Id = t2.Id WHERE t2.Id IS NULL )) BEGIN TRY BEGIN TRAN PRINT 'Deleting' DELETE TOP (@BatchSize) @Table1 FROM @Table1 t1 LEFT JOIN @Table2 t2 ON t1.Id = t2.Id WHERE t2.Id IS NULL COMMIT TRAN END TRY BEGIN CATCH ROLLBACK END CATCH SELECT * FROM @Table1
