Hi All, If anyone's interested in using it, I made a little S-SQL extension (def-sql-op :=if (a b) `(,@(case a (:null (sql-expand `(:is-null ,b))) (nil (sql-expand t)) (otherwise (sql-expand `(:= ,a ,b)))))) I find it convenient when writing queries that take optional parameters where if the parameter is not specified, you want to return the row regardless of what value b takes. Does anyone else write little extensions like these? Should we collect them in a contrib? -- Andy Chambers Software Engineer (e) achambers@mcna.net (t) 954-682-0573 CONFIDENTIALITY NOTICE: This electronic mail may contain information that is privileged, confidential, and/or otherwise protected from disclosure to anyone other than its intended recipient(s).
