$$ DELIMITER附近的语法错误

Question

i'm getting an error while creating a stored procedure, where it says that i have a syntax error, but i can't find where it is...

MySql Error:

"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 '$$DELIMITER

CREATE PROCEDURE 'entradas_sai'(IN ID_VEICULO VARCHAR(45), OUT' at line 1

Here is the code related to the topic:

$$DELIMITER

CREATE PROCEDURE 'entradas_sai'(
IN ID_VEICULO VARCHAR(45), OUT retcode INT)
BEGIN
    DECLARE '_rollback' BOOL DEFAULT 0;
    DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET '_rollback' = 1;
    START TRANSACTION;
    INSERT INTO SAIDAS(data, hora) VALUES(CURDATE("yyyy-MM-dd"),CURTIME("hh:mm:ss))
    UPDATE ENTRADAS(SAI) WITH VALUES(@SAI)
    IF '_rollback' THEN
        SET retcode = 0;
        ROLLBACK;
    ELSE
        SET retcode = 1;
        COMMIT;
    END IF;
END$$

DELIMITER ;

Here i got a scenarion of what i want my procedure to do...

I have a table called "Entradas" and one called "Saidas". Both have the column "data" and "hora". With that in mind, since the "data" and "hora column of "entradas" mean that a car joined at that date and time, and the values from the columns "data" and "hora" of "saidas" are mean to be inserted as i click a button, inserting the current date and time. I'm requesting a sql syntax that could insert the values "data" and "hora" into the table "saidas" and update a value of "entradas" called "sai" which is equal to 0 and i want it to change to 1 on button press... Any sugestion?

Answer 1

delimiter symbol ( $$ ) come after DELIMITER keyword. also use date(now()) instead CURDATE("yyyy-MM-dd") and time(now()) instead CURTIME("hh:mm:ss")) Try This

DELIMITER $$
CREATE PROCEDURE `entradas_sai`(IN ID_VEICULO VARCHAR(45), OUT retcode INT)
BEGIN
        DECLARE _rollback boolean DEFAULT 0;
        DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET _rollback = 1;
        START TRANSACTION;
        INSERT INTO SAIDAS(data, hora) VALUES(date(now()) ,time(now()));
        UPDATE ENTRADAS SET SAI = @SAI;
        IF _rollback = 1 THEN
            SET retcode = 0;
            ROLLBACK;
        ELSE
            SET retcode = 1;
            COMMIT;
        END IF;
    END$$

DELIMITER ;

Answer 2

If i'm right, you mistyped $$DELIMITER , it should be DELIMITER $$

EDIT: after adding the screenshot to the question, i believe you shouldn't quote the procedure name. I have update the code-block, try it again please.

DELIMITER $$
CREATE PROCEDURE entradas_sai(
IN ID_VEICULO VARCHAR(45), OUT retcode INT)
BEGIN
    DECLARE '_rollback' BOOL DEFAULT 0;
    DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET '_rollback' = 1;
    START TRANSACTION;
    INSERT INTO SAIDAS(data, hora) VALUES(CURDATE("yyyy-MM-dd"),CURTIME("hh:mm:ss"))
    UPDATE ENTRADAS(SAI) WITH VALUES(@SAI)
    IF '_rollback' THEN
        SET retcode = 0;
        ROLLBACK;
    ELSE
        SET retcode = 1;
        COMMIT;
    END IF;
END$$

DELIMITER ;

Answer 3

I figured what was wrong, and it wasn't only about "DELIMITER" but with a couple things more...

Here is the fixed code:

    CREATE PROCEDURE entradas_sai (
IN ID_VEICULO VARCHAR(45), OUT retcode INT)
BEGIN
    DECLARE _rollback BOOL DEFAULT 0;
    DECLARE CONTINUE HANDLER FOR SQLEXCEPTION SET _rollback = 1;
    START TRANSACTION;
    INSERT INTO SAIDAS(data, hora) VALUES(date(now()) ,time(now()));
    UPDATE ENTRADAS SET SAI=1;
    IF '_rollback' THEN
        SET retcode = 0;
        ROLLBACK;
    ELSE
        SET retcode = 1;
        COMMIT;
    END IF;
END $$

Steps: Removed the "Delimiter $$" and "Delimiter ;" and then restructured the UPDATE query. That was the main problem, because the syntax wasn't on the spot... Thanks all who tryied to help.

In this case the value of "1" wasn't the value i want... So, i changed it to @sai, which means that the value is given at a button click, which is a increment of the parameter @sai, being equal to 1,2,3,4 and so on.
