SSIS Foreach through a table, insert into another and delete the source row

Question

I have an SSIS routine that reads from a very dynamic table and inserts whichever rows it finds into a table in a different database, before truncating the original source t

Answer 1

A option, that might sound stupid but it works, is to delete first and use the OUTPUT clause.

I created a simple control flow that populates a table for me.

IF EXISTS
(
    SELECT 1 FROM sys.tables AS T WHERE T.name = 'DeleteFirst'
)
BEGIN
    DROP TABLE dbo.DeleteFirst;
END

CREATE TABLE dbo.DeleteFirst
(
    [name] sysname
);

INSERT INTO
    dbo.DeleteFirst
SELECT
    V.name
FROM
    master.dbo.spt_values V
WHERE
    V.name IS NOT NULL;

In my OLE DB Source, instead of using a SELECT, DELETE the data you want to go down the pipeline and OUTPUT the DELETED virtual table. Somethinng like

DELETE
    DF
OUTPUT
    DELETED.*
FROM
    dbo.DeleteFirst AS DF;

It works, it works!
