Question

Is it possible for a PostgreSQL plpgsql function to not return anything? I’ve created a function, and I don’t need it to return anything at all, as it performs a complex SQL query, and inserts the results of that query into another table (SELECT INTO ….). Thus, I have no need or interest in having the function return any output or value. Unfortunately, when I try to omit the RETURN clause of the function declaration, I can’t create the function. Is it possible for a PostgreSQL plpgsql function to not return anything?

Answer 1

Yes – “If the function is not supposed to return a value, specify void as the return type.” and also – “If you declared the function to return void, a RETURN statement can be used to exit the function early; but do not write an expression following RETURN.”.
