--If the table does not exist, create it, based on the staging table
IF OBJECT_ID('SCHEMANAME.TABLENAME') IS NULL
  SELECT * FROM dbo.StagingTable INTO SCHEMANAME.TABLENAME WHERE 1=0

--Insert from the staging table
INSERT INTO SCHEMANAME.TABLENAME (<columnlist>) 
SELECT <columnlist> FROM dbo.StagingTable

Is that what you mean?

Thanks Magnus... I was trying something like that but I cant pass an error. My staging table comes from a variable and also the database table.

Like my script task creates a staging table and outputs two variables TableName (Database Table name) and StagingTable (Staging Table Name)

I used a sql task and used your code.

IF OBJECT_ID('@TableName') IS NULL SELECT * FROM @StagingTable INTO @TableName WHERE 1=0

And it gives the following error:

SSIS package "Package3.dtsx" starting. Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "IF OBJECT_ID('@TableName') IS NULL SELECT * FROM..." failed with the following error: "Incorrect syntax near the keyword 'INTO'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. Task failed: Execute SQL Task SSIS package "Package3.dtsx" finished: Success. The program '[5804] Package3.dtsx: DTS' has exited with code 0 (0x0).

I know that i cannot use variables like this but can u suggest how can used them for creating the table.

Thanks

slightly modify the query IF OBJECT_ID('dbo.TestTable') IS NULL SELECT * INTO dbo.TestTable FROM dbo.MainTable WHERE 1=0
