I am new to mysql and I cant see why I have an error when I create my stored procedure.
DELIMITER |
CREATE PROCEDURE lastscan(IN task_id_var INT)
BEGIN
SELECT COUNT(*) FROM debugger WHERE task_id=task_id_var INTO #total|
SET #total=#total+1|
INSERT INTO debugger SET scan_num=#total, task_id=task_id_var|
END|
DELIMITER;
I get :
#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
I also dont get, why do I need to use that delimiter syntax.. ? DELIMITER | and then again DELIMITER;...what its function
DELIMITER |
CREATE PROCEDURE lastscan(IN task_id_var INT, IN file_name_var VARCHAR(110))
BEGIN
SELECT COUNT(*) FROM debugger WHERE task_id=task_id_var INTO #total;
SET #total=#total+1;
INSERT INTO debugger SET scan_num=#total, task_id=task_id_var, file_name=file_name_var;
END|
DELIMITER;
This works for me. no need to put | delimiter in sored procedure. I think it is meant to be for the stored procedure and not for what is inside the body
You can't simply assign variables like that, you need the SET keyword first.
http://dev.mysql.com/doc/refman/5.1/en/set-statement.html
So you code should be something like this (tested with phpMyAdmin):
DELIMITER //
CREATE PROCEDURE lastscan(IN task_id_var INT)
BEGIN
SELECT COUNT(*) FROM debugger WHERE task_id=task_id_var INTO #total;
SET #total=#total+1;
INSERT INTO debugger SET scan_num=#total, task_id=task_id_var;
END;//
DELIMITER ;
The DELIMITER keyword is used to stop additional semicolons in your procedure to be the end of the current statement, so by redefining the delimiter to // MySql will process the whole CREATE PROCEDURE-block as one single statement and not stop at the first semicolon but instead wait for the first occurrence of //.

I get that error when I try to create a procedure. I dont know what's failing and I searched a lot if someone has the same error than me, but usually they mistake at delimiters, and I think i have them right.
"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 ')
SELECT SUM(robatori.quantitat_robada) FROM robatori WHERE param1=jugador_lla' at line 1 "
My query is the next:
DELIMITER //
CREATE PROCEDURE robatoris (IN param1 VARCHAR)
SELECT SUM(robatori.quantitat_robada) FROM robatori WHERE param1=jugador_lladre;
//
DELIMITER ;
Thanks you all, that's my first question here. :)
You are missing the length for input param on type VARCHAR.
Change it like the following:
DELIMITER //
CREATE PROCEDURE robatoris ( IN param1 VARCHAR(255) )
SELECT SUM(robatori.quantitat_robada)
FROM robatori
WHERE param1=jugador_lladre;
//
DELIMITER ;
As you have only statement to execute, the BEGIN - END block was optional.
But it is advised to practice it in all cases.
DELIMITER //
CREATE PROCEDURE robatoris ( IN param1 VARCHAR(255) )
BEGIN
SELECT SUM(robatori.quantitat_robada)
FROM robatori
WHERE param1=jugador_lladre;
END;
//
DELIMITER ;
Add BEGIN and END. Use TEXT type:
DELIMITER //
CREATE PROCEDURE robatoris (IN param1 TEXT)
BEGIN
SELECT SUM(robatori.quantitat_robada)
FROM robatori
WHERE param1=jugador_lladre;
END//
DELIMITER ;
I get this error on my PHPMyAdmin

[EDIT]
Sorry, I didn't put the full thing before, i've already had an BEGIN and an END, Look.
CREATE TRIGGER `accounts_insert` BEFORE INSERT ON `accounts`
FOR EACH ROW BEGIN
SET new.RegiDate = now();
SET new.UpdateDate = now();
END;
This is the line ^^
If your trigger is only one instruction, you don't need the begin keyword:
create trigger `accounts_insert` before insert on `accounts`
for each row
set new.RegiDate = now();
If your trigger has multiple instructions, then you need to:
Change the default delimiter
Enclose the trigger instructions in a begin...end block
Restore the default delimiter
Example:
delimiter $$
create trigger `accounts_insert_2` before insert on `accounts`
for each row
begin
set new.RegiDate = now();
set #newRows = coalesce(#newRows, 0) + 1; -- Just a dummy example
end; &&
delimiter ;
Why the delimiter $$ and delimiter ; are important?
When you write a query, MySQL assumes that it ends where it finds the first standard "instruction terminator" (;). Since your trigger has more than one instruction, and every instruction must end with ;, then MySQL assumes that the trigger definition is ended, and (of course) fails to execute it. So, what can be done? Simply redefine temporally the standard instruction terminator:
delimiter $$
Now, each instruction must end with $$ to be executed. Define your trigger, and, when you want to end the definition, use your new temporary instruction terminator $$, and then redefine the terminator to the normal ;:
delimiter ;
This must be done every time you define a multi insstruction trigger or a stored procedure or function.
I'm trying to write a stored procedure in Mysql phpmyadmin, the procedure is
DELIMITER $$
DROP FUNCTION IF EXISTS `shopping_portal`.`f_authenticate_admin`$$
CREATE PROCEDURE =`root`#`localhost` FUNCTION `f_authenticate_admin`(l_username VARCHAR(50),l_password VARCHAR(50)) RETURNS int(11)
BEGIN
DECLARE exist INT DEFAULT 0;
SELECT count(*) INTO exist FROM admin WHERE username=l_username and password=MD5(l_password);
RETURN exist;
END$$
DELIMITER ;
but it is throwing the error
#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 '=`root`#`localhost` FUNCTION `f_authenticate_admin`(l_username VARCHAR(50),l_pas' at line 1
Help me in writing this procedure. Thanks in advance.
Well, multiple issues:
You're mixing procedures and functions, those are two different stories. And you're probably looking for DEFINER with your = root#localhost. And you want to use single quotes instead of backticks (I'm not sure though, if that's really an issue). Anyway, let me rewrite it for you...
DROP PROCEDURE IF EXISTS `shopping_portal`.`f_authenticate_admin`;
DELIMITER $$
CREATE DEFINER = 'root'#'localhost' PROCEDURE `f_authenticate_admin`(IN l_username VARCHAR(50), IN l_password VARCHAR(50), OUT result tinyint)
BEGIN
SELECT EXISTS(SELECT 1 FROM admin WHERE username=l_username and password=MD5(l_password)) INTO result;
END$$
DELIMITER ;
You then call it like this:
CALL f_authenticate_admin('test_username', 'a_password', #a_variable);
Then you have your result in #a_variable.
SELECT #a_variable;
Result is either 1 or 0.
I'm creating procedure which is having two parameters , one is p_cursor of type SYS_REFCURSOR (OUT param) and the other one is p_rank of type INT(IN param). But it showing an error.
DELIMITER $$
CREATE PROCEDURE sp_student(p_cursor OUT SYS_REFCURSOR,p_rank IN INT)
BEGIN
OPEN p_cursor FOR SELECT * FROM student WHERE rank = p_rank;
END$$
DELIMITER ;
the error what I'm getting is,
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 'OUT SYS_REFCURSOR,p_rank IN INT)
BEGIN
OPEN p_cursor FOR SELECT * FROM st' at line 1
I think I'm syntactically wrong for SYS_REFCURSOR.. please check my code and let me realise my mistake.
thanks in advance
mysql doesnt have refcursor like oracle, if u r planning to write a stored procedure that returns multiple rows/result set in mysql just do
DROP procedure IF EXISTS `sample`;
DELIMITER $$
CREATE PROCEDURE `sample`(p_rank IN INT)
BEGIN
select * from MyTable where id=p_rank;
END$$
DELIMITER ;
call sample();
this will return a result set. which u can use.
Hi
Is there any error in this TRIGGER Statement.When ever i try to run this in phpAdmin its giving error saying "#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 "SELECT Count(*) into SIM_CCode_Count".I cant get what's wrong in this..please help me
This is my trigger statement
CREATE TRIGGER Is_CountryCode_There After INSERT on mr_details FOR EACH ROW
BEGIN
DECLARE SIM_CCode_Count INTEGER;
DECLARE NET_CCode_Count INTEGER;
SELECT Count(*) into SIM_CCode_Count FROM Country_Main where CountryCode=NEW.SimCntISO;
IF SIM_CCode_Count=0 THEN
INSERT INTO Country_Main(CountryCode,CountryName) Values(NEW.SIMCntISO,"Unknown");
END IF
If NEW.SimCntISO<>NEW.NetCntISO then
SELECT Count(*) into NET_CCode_Count FROM Country_Main
where CountryCode=NEW.NetCntISO
IF NET_CCode_Count=0 THEN
INSERT INTO Country_Main(CountryCode,CountryName) Values(NEW.NETCntISO,"Unknown");
END IF
END IF
END
Without proper explanation about your requirement and about tables and what you are expecting this trigger to do,its very difficult to say if any issues there in your trigger..
But as far as i can see there is some minor correction need to be done..
Try this Code and let know in detail your requirements..
CREATE TRIGGER Is_CountryCode_There After INSERT on mr_details FOR EACH ROW
BEGIN
DECLARE SIM_CCode_Count INTEGER;
DECLARE NET_CCode_Count INTEGER;
SELECT Count(*) into SIM_CCode_Count FROM Country_Main where CountryCode=NEW.SimCntISO;
IF SIM_CCode_Count=0 THEN
INSERT INTO Country_Main(CountryCode,CountryName) Values(NEW.SIMCntISO,"Unknown");
END IF;
If (NEW.SimCntISO<>NEW.NetCntISO) then
SELECT Count(*) into NET_CCode_Count FROM Country_Main
where CountryCode=NEW.NetCntISO;
IF NET_CCode_Count=0 THEN
INSERT INTO Country_Main(CountryCode,CountryName) Values(NEW.NETCntISO,"Unknown");
END IF;
End IF;
END;
You have to declare a mysql-statement delimiter before the trigger statement:
DELIMITER |
CREATE TRIGGER ...
(your code)
END|
DELIMITER ;
Otherwise MySQL interprets your ; in this statement as statement commit and executes the code immidiately. With the delimiter changed to a different character you can use the semicolon inside the trigger declaration safely.
