Errors with MySQL stored function creation ERROR 1064 & 1327

Question

I am using MySQL v5.1.36 and I am trying to create a stored function using this code.

DELIMITER //
CREATE FUNCTION `modx`.getSTID (x VARCHAR(255)) RETURNS INT DETERMINISTIC
    BEGIN
    DECLARE y INT;
    SELECT id INTO y
    FROM `modx`.coverage_state
    WHERE `coverage_state`.name = x;
    RETURN y;
    END//

When entered into the MySQL Console I get this response.

mysql>  DELIMITER //
mysql>  CREATE FUNCTION `modx`.getSTID (x VARCHAR(255)) RETURNS INT DETERMINISTIC
    ->          BEGIN
    ->          DECLARE y INT;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that

mysql>          SELECT id INTO y
    ->          FROM `modx`.coverage_state
    ->          WHERE `coverage_state`.name = x;
ERROR 1327 (42000): Undeclared variable: y
mysql>          RETURN y;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'RETUR
N y' at line 1
mysql>          END//

From what I can find online my syntax is correct. What am I doing wrong?

Answer 1

When creating a function/procedure from mysql console, the first command should be DELIMITER //. Otherwise, it uses default delimiter (;),
