SSIS doesn't drop table

I have a T-SQL Statement Task to create table every time the package run. It doesn't return error but it doesn't drop the table either. The data is appended every time. The code is working fine in SQL server query window. Can you see what is wrong in the code below? TIAIF OBJECT_ID (N'M020_Vendor', N'U') IS NOT NULL DROP TABLE M020_VendorGOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCREATE TABLE [M020_Vendor]( list of fields)GO
