Subject: Problem with self-join updates...
Date: Fri, 15 Feb 2002 10:39:21 -0800
Message-ID: <002101c1b650$18f087a0$0201a8c0@osprey> (raw)

I have the following self-join update:

            update TABLE set PARENT_ID=parent.PARENT_ID
            from TABLE, TABLE parent
            where TABLE.PARENT_ID=parent.ID
            and parent.ID in (1,2,3,4)

This query is use to update a hierarchy before deleting specific records...

I get the following error:

    Table name "table" specified more than once

This appears to be a limitation of the update syntax which is not documented...

Is this something that will be fixed soon? or should I write this query differently?

Any suggestions?

Thanks for your help.

    Benoit
