fun :: Text -> Col s a -> Col s b Source #
A unary operation. Note that the provided function name is spliced directly into the resulting SQL query. Thus, this function should ONLY be used to implement well-defined functions that are missing from Selda's standard library, and NOT in an ad hoc manner during queries.
