RE: Selected lines now how do I update?

You need to use a subselect to choose the value from the other table if
I am understanding what you want to do - something like:



UPDATE MyRefTable

SET OldCLIENT = (select NewCLIENT from MyTable1 where key of MyRefTable
= key of MyTable1) WHERE OldClient in (



WITH T AS (



SELECT

NewCLIENT, OldCLIENT,

FROM MyTable1 WHERE etc, etc )



SELECT * FROM MyRefTable JOIN T ON

MyRefclient=OldCLIENT )

Subject: Selected lines now how do I update?



Hi,



I'm having a problem getting an UPDATE right after having selected the
records to update.



Here's my select :



WITH T AS (



SELECT

NewCLIENT, OldCLIENT,

FROM MyTable1 WHERE etc, etc )



SELECT * FROM MyRefTable JOIN T ON

MyRefclient=OldCLIENT









Now I want to replace the old client with the new, but this doesn't seem
to be right :



UPDATE MyRefTable

SET OldCLIENT = NewCLIENT WHERE OldClient in (



WITH T AS (



SELECT

NewCLIENT, OldCLIENT,

FROM MyTable1 WHERE etc, etc )



SELECT * FROM MyRefTable JOIN T ON

MyRefclient=OldCLIENT )





Thanks for any help.
