The stored procedure doesn't get created

I'm trying to create a stored procedure in MySql but I just get an error. Can somebody help me?

CREATE PROCEDURE colorAddOrEdit (
	in _id int,
    in _descripcion varchar(45)
    )
BEGIN
	If _id = 0 then
		insert into color (Descripcion_col)
        values (_descripcion);
        
		set _id = last_insert_id();
	else 
		update color 
        set 
		Descripcion_col = _descripcion
		where idColor_col = _id;
	end if;
    
    select _id = idColor_col;
end

The table is:

CREATE TABLE `color` 
(
    `idColor_col` int NOT NULL,
    `Descripcion_col` varchar(45) DEFAULT NULL,
    PRIMARY KEY (`idColor_col`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

The error message:

> 08:52:19 CREATE PROCEDURE colorAddOrEdit ( in _id int, in _descripcion varchar(45) ) BEGIN If _id = 0 then insert into color (Descripcion_col) values (_descripcion) Error Code: 1064. 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 '' at line 8 0.000 sec

Try this

DELIMITER //
CREATE PROCEDURE colorAddOrEdit (
    IN _id INT,
    IN _descripcion VARCHAR(45)
)
BEGIN
    IF _id = 0 THEN
        INSERT INTO color (Descripcion_col)
        VALUES (_descripcion);

        SET _id = LAST_INSERT_ID();
    ELSE
        UPDATE color 
        SET Descripcion_col = _descripcion
        WHERE idColor_col = _id;
    END IF;

    SELECT _id AS idColor_col;
END //
DELIMITER ;
