Question

Overview: Trying to write a trigger for a SQL Server 2008 database. TableA and TableB have the same schema.

Aim: On an insert into TableA, copy everything in that row to a new row in TableB

Notes so far:

Using this question I manage to get most the way, but then stumbled into a problem with

Cannot use text, ntext, or image columns in the ‘inserted’ and
‘deleted’ tables.

I just have text columns, but I want to copy them too.

I found this website which seems to have a workaround but, it is working on update, and I haven’t been able to apply it to my insert example…

Any ideas?

Edit: purpose is to add functionality to an existing product, I can’t change schema of TableA unfortunately.

I’m not sure why you can’t use the example you linked to. It should be as simple as:

CREATE TRIGGER T_TableA_I
on TableA
after insert
as
    set nocount on

    insert into TableB (ColumnA,ColumnB,/* Columns in table b */)
    select a.ColumnA,a.ColumnB, /* Columns from table a */
    from
        TableA a
            inner join
        inserted i
            on
                a.PKColumn1 = i.PKColumn1 and
                a.PKColumn2 = i.PKColumn2 /* Primary Key columns from table A */

Of course, your question doesn’t contain any table definitions, so the above will need quite a bit of modification. Hopefully, you can work out what to add/remove from the above, where comments exist.
