Re: [SQL] Sort problem

Bruce,

My apology. Actually I posted the wrong problem. Here is my problem:

IF (SortOrder = ''price'') Then
BEGIN
For rec_set IN
SELECT * from Catalog where ((VendorName ~* SearchString)
ORDER BY CASE WHEN SortOrder = ''store'' Then VendorName
WHEN SortOrder = ''category'' Then
ProductCategory Else Price END

Here is the error message:
ERROR: CASE types "numeric" and "varchar" not matched.

By the way, do you know how to do a variable (that contains 'attribute name'
instead of 'attribute value') substitution. For instance, if the attribute
name 'Price' is passed to the sort parameter ($1) so I can just do ORDER BY
$1 instead of doing case statement.

Thanks so much for your help.
Sam
