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?
