Vanilla SQL script calls a plpgsql function to delete some number of rows from three tables:SELECT mydelete(r) FROM sometable;Where sometable contains maybe 100+ records. This causes the results from the function (integer of number of rows removed) to be displayed in the output, like you'd kinda expect with a SELECT call, except I don't want to see it all, I just want the function quietly executed and rows removed.Can I accomplish this?
Pure SQL, no, you cannot just ignore the output. You can perform post-processing (via CTE/WITH) to reduce how much is printed (aggregates). If you are using psql you can send it to /dev/null. You could use a DO block and (kinda) ignore the result (SQL) and/or stick it into a throw-away variable (plpgsql).
