创建函数时出现mysql语法错误

Question

DROP FUNCTION IF EXISTS bramkiStracone;

CREATE FUNCTION bramkiStracone(idDruzyny INT)
RETURNS int(11)
DETERMINISTIC
BEGIN
DECLARE bramek INT;
DECLARE tmp1 INT;
DECLARE tmp2 INT;

SELECT DISTINCT COALESCE(SUM( b.bramki ), 0) INTO tmp1
FROM LigaBramki b
INNER JOIN LigaZawodnicy z ON b.idZawodnika = z.idZawodnika
INNER JOIN LigaDruzyny d ON z.idDruzyny = d.idDruzyny
INNER JOIN LigaMecze m ON b.idMeczu = m.idMeczu
WHERE m.idDruzyny2 = idDruzyny
AND z.idDruzyny != idDruzyny
AND d.idDruzyny != idDruzyny
AND m.rozegrany = '1';

SELECT DISTINCT COALESCE(SUM( b.bramki ), 0) INTO tmp2
FROM LigaBramki b
INNER JOIN LigaZawodnicy z ON b.idZawodnika = z.idZawodnika
INNER JOIN LigaDruzyny d ON z.idDruzyny = d.idDruzyny
INNER JOIN LigaMecze m ON b.idMeczu = m.idMeczu
WHERE m.idDruzyny1 = idDruzyny
AND z.idDruzyny != idDruzyny
AND d.idDruzyny != idDruzyny
AND m.rozegrany = '1';

SET bramek = tmp1 + tmp2;

RETURN bramek;
END

I have error near DECLARE bramek INT; but don't know what am i missing,
i tried to make it work by removing semi-colons but that didn't work either.

after i added delimiter i still have 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 FUNCTION bramkiStracone(idDruzyny INT)
RETURNS int(11)
DET' at line 1 

Answer 1

dont forget to change the default DELIMITER so the query won't terminate at DECLARE bramek INT;

DROP FUNCTION IF EXISTS bramkiStracone;

DELIMITER $$

CREATE FUNCTION bramkiStracone(idDruzyny INT)
RETURNS int(11)
DETERMINISTIC
BEGIN
DECLARE bramek INT;
DECLARE tmp1 INT;
DECLARE tmp2 INT;

SELECT DISTINCT COALESCE(SUM( b.bramki ), 0) INTO tmp1
FROM LigaBramki b
INNER JOIN LigaZawodnicy z ON b.idZawodnika = z.idZawodnika
INNER JOIN LigaDruzyny d ON z.idDruzyny = d.idDruzyny
INNER JOIN LigaMecze m ON b.idMeczu = m.idMeczu
WHERE m.idDruzyny2 = idDruzyny
AND z.idDruzyny != idDruzyny
AND d.idDruzyny != idDruzyny
AND m.rozegrany = '1';

SELECT DISTINCT COALESCE(SUM( b.bramki ), 0) INTO tmp2
FROM LigaBramki b
INNER JOIN LigaZawodnicy z ON b.idZawodnika = z.idZawodnika
INNER JOIN LigaDruzyny d ON z.idDruzyny = d.idDruzyny

WHERE m.idDruzyny1 = idDruzyny
AND z.idDruzyny != idDruzyny
AND d.idDruzyny != idDruzyny
AND m.rozegrany = '1';

SET bramek = tmp1 + tmp2;

RETURN bramek;
END $$

DELIMITER ;

Answer 2

You need to change your client's statement delimiter, so that it doesn't think each ; terminates the entire CREATE FUNCTION statement.

In the MySQL command line client, one can use the delimiter command:

delimiter ;;

CREATE FUNCTION ...  ;;

delimiter ;

Read the manual on Defining Stored Programs .

Answer 3

Make sure you set the delimiter to something other than semicolon before you declare your function:

DELIMITER |
CREATE FUNCTION bramkiStracone(idDruzyny INT)
RETURNS int(11)
DETERMINISTIC
BEGIN
DECLARE bramek INT;
...
END|
