<julius@nsoft.lt> Hello
lets say I have a function add_user(user varchar(20), password varchar(20)). In its body I want to have statement INSERT INTO my_users(user, password) VALUES (user, password); The problem is I cant - then I try to create such function I get "ERROR: syntax error at or near "$1"
LINE 1: INSERT INTO my_users( $1 .... " This tells me the parameter is used instead of column name. That is of course not what I wanted. What would you recommend to fix this? Is there any way to tell the postgres that user is column name? I tried "user" with same error. Must I change the names of parameters?
using PG 8.3
You won't have to change the parameters in the function definition, instead you can use the RENAME clause:
CREATE OR REPLACE FUNCTION add_user(user varchar(20), password varchar(20) ) RETURNS VOID AS $$
DECLARE
RENAME user TO x_user;
RENAME pa TO x_password;
BEGIN
INSERT INTO my_users(user, password) VALUES (x_user, x_password);
END; LANGUAGE plgpsql;
regards
Szymon
