• roughly, the trigger is going to look something like this, but the DDL asked for in the post above would make it definitive:

    we don't know what columns you want to audit, or the PK of the table. i hope you can figure out the changes required to my model here:

    CREATE TRIGGER TR_TrackChangesInMain ON MAIN

    FOR UPDATE

    AS

    INSERT INTO AuditTable(ColumnList)

    SELECT ColumnList

    FROM INSERTED

    INNER JOIN DELETED ON INSERTED.ID = DELETED.ID

    WHERE ISNULL(INSERTED.start_date,'1900-01-01') <> ISNULL(DELETED.start_date,'1900-01-01')
