I'm just trying to create my first mysql stored procedure and I'm trying to copy some examples almost directly from the documentation, but it isn't working:
mysql> delimiter //
mysql> CREATE PROCEDURE ghost.test (OUT param1 INT) INSERT into admins SELECT COUNT(*) FROM bans; END//
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 '; END' at line 1
What is the deal here? This is almost identical to:
mysql> delimiter //
mysql> CREATE PROCEDURE simpleproc (OUT param1 INT)
-> BEGIN
-> SELECT COUNT(*) INTO param1 FROM t;
-> END//
Query OK, 0 rows affected (0.00 sec)
From
http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html
Looks like you're missed the BEGIN.

It is simple to write a sql procedure.
demiliter //
create procedure show_growth()
begin
SELECT * from tb;
end //
I want to add a if statement in the procedure.
Drop it first.
drop procedure show_growth //
Then create a new one.
create procedure show_growth(in type char(3))
-> begin
-> if type = "all" then
-> SELECT * from tb;
-> endif
-> end //
ERROR 1064 (42000): 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 'end' at line 6
How to fix it?
endif is not 1 word.
begin
if type = "all" then
SELECT * from tb;
end if;
end
mysql> show tables;

mysql> create procedure hello()
-> begin
-> select * from product;
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 am not sure what is causing this syntax error, and haven't had any success so far figuring it out. Any help would be much appreciated.
You need to use the DELIMITER keyword:
This is so MySQL can tell which statements are within the procedure and where the end of the procedure declaration itself is
delimiter //
CREATE PROCEDURE hello()
BEGIN
select * from product;
END//
delimiter ;
You need a delimiter otherwise the console does not know when you are finished:
DELIMITER //
CREATE PROCEDURE hello()
BEGIN
SELECT * FROM product;
END //
DELIMITER ;
Read more about it here: Getting Started with MySQL Stored Procedures
DELIMITER $$
CREATE PROCEDURE abc(IN _uid VARCHAR(15))
BEGIN
SELECT COUNT(filename)
FROM file
WHERE userid = _uid
UNION ALL
SELECT COUNT(file)
FROM fileupload
WHERE userid = _uid
END $$
DELIMITER ;
As this my query , As I need two select statement output
but it getting 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 'END' at line 10
Try:
mysql> DELIMITER $$
mysql> CREATE PROCEDURE abc(IN _uid VARCHAR(15))
-> BEGIN
-> SELECT COUNT(filename)
-> FROM file
-> WHERE userid = _uid
-> UNION ALL
-> SELECT COUNT(file)
-> FROM fileupload
-> -- WHERE userid = _uid
-> WHERE userid = _uid;
-> END$$
Query OK, 0 rows affected (0.00 sec)
mysql> DELIMITER ;
CREATE PROCEDURE `go`()
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN DECLARE d_z CONDITION FOR SQLSTATE '35241';
SELECT COUNT(*)as #a from _time
IF #a>0 THEN
SIGNAL d_z SET MESSAGE_TEXT='errrrrrrrrrrrr';
END IF;
END;
error: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 '#a from _time
IF #a>0 THEN SIGNAL d_z SET MESSAGE_TEXT='errrrrrrrrrr' at line 9
The problem is with the select statement "#a" is alias name which cant be used further queries.
You can use peterm query "into" instead of as
Hope this helps
Happy Coding
You has some syntax issues. Following works for me:
DELIMITER //
CREATE PROCEDURE `go`()
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
DECLARE d_z CONDITION FOR SQLSTATE '35241';
select count(*) INTO #a from _time;
IF #a>0 THEN
SIGNAL d_z SET MESSAGE_TEXT='errrrrrrrrrrrr';
END IF;
END
//
Important is to:
Use into #variable syntax for selecting a value into a var
Use DELIMITER for termination of multiline procedure body
Your immediate error is caused by the malformed SELECT statement. You have to a proper SELECT INTO syntax
Change
SELECT COUNT(*)as #a from _time
to
SELECT COUNT(*) INTO #a FROM _time
^^^^
Now there are several other issues with your code:
There is no need to use a user(session) variable, you could've used local variable instead
You don't want to get total number of all rows just to tell whether you have rows or not in your table. If you do you'll pay performance penalty (if of course you're not using MyISAM). You can leverage NOT EXISTS() for that or LIMIT 1 clause.
That being said a streamlined version of your procedure might look like
DELIMITER $$
CREATE PROCEDURE `go`()
BEGIN
DECLARE d_z CONDITION FOR SQLSTATE '35241';
IF NOT EXISTS(SELECT * FROM _time) THEN
SIGNAL d_z SET MESSAGE_TEXT='errrrrrrrrrrrr';
END IF;
END$$
DELIMITER ;
Here is SQLFiddle demo
Let's give it a try
mysql> CREATE TABLE _time (`id` int);
Query OK, 0 rows affected (0.03 sec)
mysql> DELIMITER $$
mysql> CREATE PROCEDURE `go`()
-> BEGIN
-> DECLARE d_z CONDITION FOR SQLSTATE '35241';
-> IF NOT EXISTS(SELECT * FROM _time) THEN
-> SIGNAL d_z SET MESSAGE_TEXT='errrrrrrrrrrrr';
-> END IF;
-> END$$
Query OK, 0 rows affected (0.02 sec)
mysql> DELIMITER ;
mysql> CALL go();
ERROR 1644 (35241): errrrrrrrrrrrr
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.
