I am not strong in PhpMyAdmin, nor in MySql nonstandard syntax. I am trying to create a simple stored procedure using PhpMyAdmin and the engine just repeats the same:
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 3
Simple stored procedure is:
CREATE PROCEDURE proc_test()
BEGIN
DECLARE int_val INT;
SET int_val = int_val + 1;
SELECT int_val;
END;
Here is the version:
select ##version
5.6.28
I am starting to hate MySql. Why I can not manage to create such a simple stored procedure?
You need to add some delimiter to the code. This should do:
DELIMITER $$
CREATE PROCEDURE proc_test()
BEGIN
DECLARE int_val INT;
SET int_val = int_val + 1;
SELECT int_val;
END $$
you should use the DELIMITER. link.
DELIMITER //
CREATE PROCEDURE proc_test()
BEGIN
DECLARE int_val INT;
SET int_val = int_val + 1;
SELECT int_val;
END //
DELIMITER ;
but when you call this procedure it always show null. so you should set int_val value by DEFAULT value or using SET
DECLARE int_val INT DEFAULT 0;
OR
SET int_val = 0

I try to update some columns using trigger before insert
DROP TRIGGER IF EXISTS update_p_posts_places;
DELIMITER $$
CREATE TRIGGER update_p_posts_places BEFORE
INSERT
ON
`p_posts` FOR EACH ROW
BEGIN
DECLARE
p_post_group_id_ int;
SELECT
`p_post_subgroup`.`p_post_group_id`

`p_post_subgroup`.`p_post_subgroup_id` = NEW.p_post_subgroup_id;
IF(p_post_group_id_ = 5) THEN

It's showing some syntax errors.

Here is a working trigger. I tested creating it on MySQL 5.7.
CREATE TRIGGER update_p_posts_places BEFORE INSERT ON `p_posts`
FOR EACH ROW
BEGIN
-- all declarations must be before any other statements
DECLARE p_post_group_id_, place1_id_, place2_id_, place3_id_,
place4_id_, place5_id_ int;
SELECT
`p_post_subgroup`.`p_post_group_id`
INTO
p_post_group_id_
FROM
`p_post_subgroup`
WHERE
`p_post_subgroup`.`p_post_subgroup_id` = NEW.p_post_subgroup_id;
IF(p_post_group_id_ = 5) THEN
SELECT
`Places`.`place1_id`,
`Places`.`place2_id`,
`Places`.`place3_id`,
`Places`.`place4_id`,
`Places`.`place5_id`
INTO
place1_id_, place2_id_, place3_id_, place4_id_, place5_id_
FROM
`Places`
WHERE
`Places`.`place5_id` = NEW.p_post_place_id LIMIT 1;
SET NEW.place5_id = place5_id_;
SET NEW.place1_id = place1_id_;
SET NEW.place2_id = place2_id_;
SET NEW.place3_id = place3_id_;
SET NEW.place4_id = place4_id_;
ELSE
SET NEW.place5_id = NULL;
END IF;
END $$
You can use one DECLARE for multiple local variables, but you must do like var1, var2, var3, ... int. In other words, name the type only once at the end. See documentation: https://dev.mysql.com/doc/refman/8.0/en/declare-local-variable.html
No need for the BEGIN..END inside the IF and definitely do not use $$ until after the last END because that will terminate the parser's interpretation of your whole CREATE TRIGGER statement before it's complete.
Hi i am creating some trigger for update the value in insert query before insert the row like this
CREATE TRIGGER `Insert members in Posts` BEFORE INSERT ON
`posts` FOR EACH ROW
BEGIN
DECLARE name_ varchar(100);
DECLARE contact_ varchar(16);
DECLARE status_ int;
DECLARE deleted_ int;
SELECT
`members`.`name`,
`members`.`contact`,
`members`.`status`,
`members`.`deleted`
INTO name_, contact_, status_, deleted_
FROM
`members`
WHERE
`members`.`member_id` = NEW.member_id;
SET NEW.member_name = name_;
SET NEW.member_contact = contact_;
SET NEW.member_status = status_;
SET NEW.member_deleted = deleted;
END
But i received the error like
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 4
I am little confused what's the error in line no 4. Please explain someone. Thanks.
Depending on the client/ide used you may need to set delimiter for example
drop trigger if exists t;
delimiter $$
CREATE TRIGGER t BEFORE INSERT ON
`posts` FOR EACH ROW
BEGIN
DECLARE name_ varchar(100);
DECLARE contact_ varchar(16);
DECLARE status_ int;
DECLARE deleted_ int;
SELECT
`members`.`name`,
`members`.`contact`,
`members`.`status`,
`members`.`deleted`
INTO name_, contact_, status_, deleted_
FROM
`members`
WHERE
`members`.`member_id` = NEW.member_id;
SET NEW.member_name = name_;
SET NEW.member_contact = contact_;
SET NEW.member_status = status_;
SET NEW.member_deleted = deleted;
END $$
delimiter ;
please review https://dev.mysql.com/doc/refman/8.0/en/stored-routines.html
I'm using MySql57
What's wrong with this script?(I'm Mysql newbie)
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 '= 'A0001'; ELSE BEGIN gubun1 = LEFT(cur_max,0,1); gu' at line 10
DELIMITER $$
CREATE FUNCTION narae.FN_GET_GUBUN_MAX() RETURNS varchar(100)
BEGIN
DECLARE cur_max varchar(100);
DECLARE gubun1 varchar(1);
DECLARE gubun2 varchar(100);
DECLARE RTN_VAL varchar(100);
SELECT IFNULL(MAX(gubun_code),'A0001') INTO cur_max from gubun_code;
IF cur_max = 'A0001' THEN RTN_VAL = 'A0001';
ELSE
BEGIN
gubun1 = LEFT(cur_max,0,1);
gubun2 =
LPAD(CONVERT(CONVERT(RIGHT(cur_max,4),UNSIGNED)+1,CHAR),4,'0');
RTN_VAL = CONCAT(gubun1,gubun2);
END
RETURN RTN_VAL;
END $$
DELIMITER ;
There are several errors in the function. I think this might work:
DELIMITER $$
CREATE FUNCTION narae.FN_GET_GUBUN_MAX() RETURNS varchar(100)
BEGIN
DECLARE v_cur_max varchar(100);
DECLARE v_RTN_VAL varchar(100);
SELECT COALESCE(MAX(gubun_code), 'A0001')
INTO v_cur_max
FROM gubun_code;
IF cur_max = 'A0001' THEN
SET v_RTN_VAL = 'A0001';
ELSE
SET v_RTN_VAL = CONCAT(LEFT(cur_max, 1), RIGHT(cur_max, 4) + 1);
END IF;
RETURN v_RTN_VAL;
END $$
DELIMITER ;
I would further simplify this by doing all the logic in the SQL statement, but this seems to be in the spirit of your solution.
I am a newbie to mysql, I and I have written a stored procedure in which I am always getting syntax errors , I am using SQL Workbench 6.0, Could some one please help know what am I doing wrong.
CREATE DEFINER=`root`#`localhost` PROCEDURE `loginAuthentication`(IN user_name VARCHAR(45),IN pass VARCHAR(45),OUT returnvalue INT)
BEGIN
DECLARE no_of_records INT; (Syntax Error on this Line)
SELECT COUNT(*) INTO no_of_records
FROM tablename.registration
WHERE tablename.registration.user_name=user_name AND tablename.registration.pass=pass;
IF no_of_records = 1 THEN (Syntax Error on this Line)
SET returnvalue = 1;
END IF; (Syntax Error on this Line)
END; (Syntax Error on this Line)
You have to change the delimiter. Otherwise MySQL thinks that your procedure ends after the very first ;
Write it like this:
DELIMITER $$
CREATE DEFINER=`root`#`localhost` PROCEDURE `loginAuthentication`(IN user_name VARCHAR(45),IN pass VARCHAR(45),OUT returnvalue INT)
BEGIN
DECLARE no_of_records INT;
SELECT COUNT(*) INTO no_of_records
FROM tablename.registration
WHERE tablename.registration.user_name=user_name AND tablename.registration.pass=pass;
IF no_of_records = 1 THEN
SET returnvalue = 1;
END IF;
END $$
DELIMITER ;
And btw, Workbench has nothing to do with it. It's just a client to MySQL.
