What is wrong with this stored procedure?

问题

I keep getting this error for the below MySQL SP any ideas?

CREATE PROCEDURE productpricing(
OUT pl DECIMAL(8,2), OUT ph DECIMAL(8,2), OUT pa DECIMAL(8,2) ) BEGIN SELECT Min(amount) INTO pl FROM Card 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 9 0.000 sec

DROP PROCEDURE IF EXISTS productpricing;
CREATE PROCEDURE productpricing(
   OUT pl DECIMAL(8,2),
   OUT ph DECIMAL(8,2),
   OUT pa DECIMAL(8,2)
)
BEGIN
   SELECT Min(amount)
   INTO pl
   FROM Card;
END;

回答1:

Did you define a delimiter?

Try adding delimiter // before the CREATE PROCEDURE statement. Also replace END; with END;//. I checked and it works for me.

See the MySQL doc on stored procedures

you need group by if you use min,max i think. if that doesnt work try #p1 to create a temp table. May be problem is the table you are inserting it to.
