Hey guys i am facing a problem when i use a variable with a case in mysql.
The code which i have used is
DECLARE vSite VARCHAR(20);
SET vSite = case
when id > 0 then 'sdfsdf'
else 'asd' end as name
from customers;
When i run this code it throws me 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 'DECLARE vSite VARCHAR(20)' at line 1: DECLARE vSite VARCHAR(20)
CAN anyone point me where am going wrong..Thanks for your valuable help
You need to declare variables inside a BEGIN END block.
Here is a simple example of a stored procedure
DELIMITER //
CREATE procedure blah(IN customer_id INT,OUT vSite VARCHAR(20))
BEGIN
SELECT CASE WHEN id > 0 THEN 'blah'
ELSE 'mah' END INTO vSite FROM customers WHERE id=customer_id;
END//
DELIMITER ;
CALL blah(3,#somevar);
SELECT #somevar;

I tried to make a simple procedure in MariaDB 10.2 but I encountered an issue regarding variables defining.
I am receiving (conn:107) 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 3 message when I declare a variable.
I read the MariaDB documentation and I it says that a variable is defined like this DECLARE var_name [, var_name] ... type [DEFAULT value]
Where I am wrong? I am coming from Oracle SQL and some sintax is wired for me.
I use Eclipse with MariaDB JDBC to connect on SQL.
CREATE PROCEDURE nom_jobs_insert(IN p_name varchar(100) CHARACTER SET 'utf8')
BEGIN
DECLARE counter INT DEFAULT 0;
SELECT count(*) INTO counter
FROM nom_jobs
WHERE lower(name) = lower(p_name)
IF counter = 1 THEN
INSERT INTO nom_jobs(name) VALUES (p_name);
END IF;
END;
I found the solution.
In MariaDB you have to define a delimiter before create a procedure and you need to mark where the procedure code is finished.
DELIMITER //
CREATE PROCEDURE nom_jobs_insert(IN p_name varchar(100) CHARACTER SET 'utf8')
BEGIN
DECLARE counter INT DEFAULT 0;
SELECT count(*) INTO counter
FROM nom_jobs
WHERE lower(name) = lower(p_name);
IF counter = 1 THEN
INSERT INTO nom_jobs(name) VALUES (p_name);
END IF;
END; //
You have error not in DECLARE expression, add ; after SELECT statement
Here are the clues that point to a missing DELIMITER:
near '' at line 3
Line 3 contains the first ;
When the error says near '', the parser thinks it has run off the end of the "statement".
Put those together -- it thinks that there is one 3-line statement ending with ;. But the CREATE PROCEDURE should be longer than that.
CREATE PROCEDURE nom_jobs_insert(IN p_name varchar(100) CHARACTER SET 'utf8')
IS
DECLARE counter INTEGER DEFAULT 0;
BEGIN
SELECT count(*) INTO counter
FROM nom_jobs
WHERE lower(name) = lower(p_name)
IF counter = 1 THEN
INSERT INTO nom_jobs(name) VALUES (p_name);
END IF;
END;
I am using MySQL v5.0.92 and I'm trying to import some data, but I get an error on declare my variables.
BEGIN
DECLARE flag INT;
DECLARE id INT;
while flag=0 begin
SET id=(SELECT top 1 user_id
FROM ac_user_info WHERE user_id>#id order by user_id)
INSERT INTO cuddleew_database1.cewp_usermeta(user_id,meta_key,meta_value)
SELECT id,'first_name',first_name
FROM cuddleew_backup.ac_user_info WHERE user_id=#id
INSERT INTO cuddleew_database1.cewp_usermeta(user_id,meta_key,meta_value)
SELECT id,'last_name',last_name
FROM cuddleew_backup.ac_user_info WHERE user_id=#id
SET flag=(select case #id when(SELECT MAX(user_id)
FROM cuddleew_bakup.ac_user_info) then 1
else 0
END CASE)
END WHILE
END
In MySQL console i get this:
BEGIN DECLARE flag INT;
#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 'DECLARE flag INT' at line 2.
Can you help me with this and tell me what's wrong. Thanks in advance.
You have to change your delimiter first, so the ; doesn't tell MySQL that this command is over.
DELIMITER $$
[your code here]
END $$
DELIMITER ;
I have this piece of code:
BEGIN
DECLARE #NewLine CHAR(2)
SET #NewLine = CHAR(13)+CHAR(10)
END
When I run it in phpmyadmin, I get this 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 'DECLARE #NewLine CHAR(2) SET #NewLine = CHAR(13) + CHAR(10) END' at line 2
I used about 2 hours on Google, without any luck. As far as I can tell, it should be the right syntax.
Someone please help
Flow statements like IF, WHEN and so on are only allowed in stored procedures or function in MySQL. BEGIN and END are delimiters of such statements.
Put that code in a procedure and it should work.
Edit
Example procedure
DELIMITER //
CREATE PROCEDURE newline_proc(input varchar(1000))
BEGIN
declare newline char(2);
select CHAR(13)+CHAR(10) into newline;
...
END//
DELIMITER ;
I'm a bit of a noob when it comes to stored procedures in general, but I'm trying to write the following
Create procedure clone_perms
as
declare #new_id varchar(30), #old_id varchar(30)
declare get_perms cursor for select userspermsUserid, userspermsPermission from users_permissions where userspermsUserid=#old_id
declare #perms varchar(30), #on_off boolean
FETCH get_perms into #perms, #on_off
while(##sqlstatus=0)
BEGIN
if exists ( select 1 from permissions where userspermsUserid=#new_id and userspermsPermID=#perm )
BEGIN
update permissions set userspermsPermission=#on_off where userspermsUserid=#new_id and userspermsPermID=#perm
END
else
BEGIN
insert permissions (userspermsUserID, userspermsPermID, userspermsPermission) values (#new_id, #perms, #on_off)
END
FETCH get_perms into #perms, #on_off
END
CLOSE get_perms
DEALLOCATE CURSOR get_perms
end
. I get the following error when trying to create it:
/* SQL 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 'as declare #new_id varchar(30) declare #old_id varchar(30) declare get_perm' at line 2 */
. Does anyone know what I need to do to make this work?
You need to have BEGIN tag after CREATE PROCEDURE clone_perms and not AS
don't use an # to start local (declared) variable names, that's only for user variables you create with the
SET #varname=value;
statement. you'll also need to terminate your statements with a semicolon. that's the cause of the latest error, there's no ; after your first declare statement.
I have a hard time locating an error when trying to create a stored procedure in mysql.
If I run every single line of the procedure independently, everything works just fine.
CREATE PROCEDURE cms_proc_add_child
(
param_parent_id INT, param_name CHAR(255),
param_content_type CHAR(255)
)
BEGIN
SELECT #child_left := rgt FROM cms_tree WHERE id = param_parent_id;
UPDATE cms_tree SET rgt = rgt+2 WHERE rgt >= #child_left;
UPDATE cms_tree SET lft = lft+2 WHERE lft >= #child_left;
INSERT INTO cms_tree (name, lft, rgt, content_type) VALUES
(
param_name,
#child_left,
#child_left+1,
param_content_type
);
END
I get the following (helpful) error:
ERROR 1064 (42000): 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 just don't know where to start debugging, as every single one of these lines is correct.
Do you have any tips?
As line 3 contains the first ; perhaps you have a problem with your delimiters.
See http://dev.mysql.com/doc/refman/en/stored-programs-defining.html
DELIMITER //
CREATE PROCEDURE dorepeat(p1 INT)
BEGIN
SET #x = 0;
REPEAT SET #x = #x + 1; UNTIL #x > p1 END REPEAT;
END//
DELIMITER ;
Thanks, near '' at line 3 was my problem and the delimiter statement fixed it! I always want things to make sense and this does. As the '' indicates it's at the end of the procedure, but no END statement was found thus the syntax error. And I wondered why I kept seeing a lot of people using the delimiter statement. I see the light!
You never declare your #child_left variable.
If you having issues with a bunch of Procedure that can't run at the same time but can run successfully alone, Try separate them with Go command.
Ex:
--i)
CREATE PROCEDURE A
AS
BEGIN
END;
GO
--ii)
CREATE PROCEDURE B
AS
BEGIN
END;
