It's a simple procedure, I just cannot for the life of me find the error in this syntax. I've learned at other posts and couldn't find a working solution.
CREATE PROCEDURE cooldownUpdate #command VARCHAR(18)
AS
UPDATE `mention_cooldowns` SET cooldown = 'true' WHERE command = #command
GO;
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 '#command VARCHAR(18) AS UPDATE mention_cooldowns SET cooldown = 'true' WHERE c' at
line 1
Firstly, you have to set a delimiter while creating stored procedure. Also, you have to define whether the parameter is for IN or OUT and finally you have to wrap your queries inside BEGIN and END for best practice.
Please check below for creating stored procedure.
DELIMITER //
CREATE PROCEDURE cooldownUpdate(IN pCommand VARCHAR(18))
BEGIN
UPDATE `mention_cooldowns` SET cooldown = 'true' WHERE command = pCommand;
END //
DELIMITER ;

This is my first time trying to create a MySql trigger but I'm running into syntax errors that I can't identify. I am trying to have the trigger insert a calculated value when a row is updated. Below is my code, but I keep getting syntax errors when I try to execute it, and I cannot see where the error is. Can someone please look, what am I doing wrong?
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END;
Here is the error I get in MySQL Workbench, but it's not much help. :/
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 5
MySQL Workbench highlights the end of line 6 as the start of the syntax error.
As said by #Akina I was missing the delimiter statements. Here is fixed code.
delimiter //
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END//
delimiter ;
As per the advice of #Akina I read the Create Procedure documentation from the dev.mysql.com site and the below quote highlighted the importance of using delimiter
The example uses the mysql client delimiter command to change the statement delimiter from ; to // while the procedure is being defined. This enables the ; delimiter used in the procedure body to be passed through to the server rather than being interpreted by mysql itself. See Section 25.1, “Defining Stored Programs”.
i wat to create this trigger to set a defaul value for a clomn but i get this message error : #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 4
this is my script :
CREATE TRIGGER trg_set_content_val BEFORE INSERT
ON post_table
FOR EACH ROW BEGIN
set NEW.content = 'mu value here';
END;
You need to set the delimiter to something else than semicolon before the stored program and then change it back:
DELIMITER //
CREATE TRIGGER trg_set_content_val
BEFORE INSERT
ON post_table
FOR EACH ROW BEGIN
set NEW.content = 'mu value here';
END//
DELIMITER ;
Reason:
If you use the mysql client program to define a stored program
containing semicolon characters, a problem arises. By default, mysql
itself recognizes the semicolon as a statement delimiter, so you must
redefine the delimiter temporarily to cause mysql to pass the entire
stored program definition to the server.
To redefine the mysql delimiter, use the delimiter command. The
following example shows how to do this for the dorepeat() procedure
just shown. The delimiter is changed to // to enable the entire
definition to be passed to the server as a single statement, and then
restored to ; before invoking the procedure. This enables the ;
delimiter used in the procedure body to be passed through to the
server rather than being interpreted by mysql itself.

My Trigger
CREATE TRIGGER `register_notification_after_register`
`AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
try this:
DELIMITER $$
CREATE TRIGGER `register_notification_after_register`
AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
$$ -- I am done server, end of block
DELIMITER ;
you had an extra backtick on line two. One needs to set the DELIMITER to block the whole thing. With create event, create stored proc, create trigger, delimiters clue the server into when the whole chunk is done. Remember that the ; ends a statement. The delimiter statement suspends that in favor of something else, then resets at end of block
I am trying to make a procedure to update an existing user. It receives the name of the user and then increments his points column. I have it like this:
CREATE PROCEDURE addPoints (IN nomeus varchar(20))
BEGIN
UPDATE User
SET
points=points+1
WHERE (nome=nomeus) ;
END;
However, I get this error:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 8
How can I fix it?
When in doubt just go to dev.mysql they have some great documentation there.
http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html
Looks like you found the answer to your own question. However, if you change any of the code in the procedure, don't forget to drop the procedure before trying to create it again.
Drop Procedure if exists addPoints;
http://dev.mysql.com/doc/refman/5.0/en/drop-procedure.html
Yeah, I had to use delimiters:
delimiter //
CREATE PROCEDURE addPoints(IN nomeuser varchar(256))
BEGIN
UPDATE User
SET
points = points + 1
WHERE nome = nomeuser;
END;//
delimiter ;
Here is my stored procedure for returning true if any data is found in document details but it generates an 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 '#result = true end if end' at line 5"
create procedure abcde(out result boolean)
begin
if exists(select * from document_details)
then #result = true;
end if
end
Kindly,provide me a solution asap
Besides the fact that you need to use SET to assign a value to a local variable or a parameter, there are other things worth mentioning
you have to have a semicolon after END IF
since EXSITS() returns BOOLEAN you can just directly assign it to your OUT parameter
That being said your stored procedure might look like
CREATE PROCEDURE abcde(OUT result BOOLEAN)
SET result =
(
EXISTS(SELECT *
FROM document_details)
);
Note: now it's just one statement. Therefore you don't even need to change DELIMITER and use BEGIN ... END block.
