RE: stored procedure - Ambiguous column name
Try renaming your stored proc input parameter CategoryJobDescrID to something else so it doesn't have the same name as a database column. --- Greg Jordan <[EMAIL PROTECTED]> wrote: = I-Lin Kuo Macromedia CF5 Advanced Developer Sun Certified Java 2 Programmer __ Do You Yahoo!?

Re: stored procedure - Ambiguous column name
Greg,
Only thing I can see that isn't going to help is : dbvarname="@orderyby" in
one of your tags
Are you sure you're sure that attributes.orderby isn't being changed before
you get to the SP call? Mind you ORDER BY .. isn't going to help your
SELECT statement.
Regards
Stephen

Greg,
categoryJobDescrID is in both you categoryJobDescr and categoryJobListing
table.
The procedure looks ok, so I can only assume that you are passing through
categoryJobDescrID as one of the fields in @orderby without a tablename
prefix.

RE: stored procedure - Ambiguous column name
Greg,
This error usually indicates a failure to properly alias during a join -
where the driver can't figure out which table to pull "jobdescId" from.

Re: stored procedure - Ambiguous column name
Greg,
categoryJobDescrID is in both you categoryJobDescr and categoryJobListing
table.
The procedure looks ok, so I can only assume that you are passing through
categoryJobDescrID as one of the fields in @orderby without a tablename
prefix.

Stephen
