Syntax error in MySQL Function - mysql

I'm trying to set up a MySQL function for my Mail-server. The MySQL Version is 5.1.66.
I do know what is wrong with this query. I also tried with RETURN DOUBLE, READS SQL DATA, and DETERMINISTIC but none of them help.
I am using PhpMyAdmin. The delimiter is set to $$. But all I get is a cryptic error message:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TEXT CHARSET utf8 READS SQL DATA BEGIN DECLARE mygoto VARCHAR(25' at line 3
My code:
CREATE PROCEDURE `get_email_alias`(
myemail VARCHAR(255)
) RETURNS TEXT CHARSET utf8
READS SQL DATA
BEGIN
DECLARE mygoto VARCHAR(255);
DECLARE sdomain VARCHAR(255);
DECLARE ddomain VARCHAR(255);
SELECT SUBSTRING(myemail, INSTR(myemail, '#')+1) INTO sdomain;
SELECT target_domain
FROM alias_domain
WHERE alias_domain = sdomain
AND active = 1
LIMIT 1
INTO ddomain;
IF ddomain IS NOT NULL THEN
SELECT REPLACE(myemail, sdomain, ddomain) INTO myemail;
END IF;
SELECT goto
FROM alias
WHERE address = myemail
AND active = 1
LIMIT 1
INTO mygoto;
IF mygoto IS NOT NULL THEN
RETURN mygoto;
END IF;
RETURN null;
END $$

For anyone that comes across this later:
There was originally a syntax error in the keyword PROCEDURE. It was missing the final E.
According to the MySQL syntax, CREATE PROCEDURE does not RETURN. However, CREATE FUNCTION does allow the RETURN in the syntax. Reference: http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html.

PROCEDURE" on first line is missing "E"

Mysterious error in CREATE PROCEDURE in MariaDB/MySQL

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;

Syntax error in sql create function

I'm getting the following error whenever i'm trying to create the following function in mysql.
error : 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
And my function is
CREATE FUNCTION GET_HOUR_MINUTES(seconds INT)
RETURNS VARCHAR(16)
BEGIN
DECLARE result VARCHAR(16);
IF seconds >= 3600 THEN SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%kh %lm');
ELSE SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%lm');
RETURN result;
END
You need to change the delimiter before creating a function. If you don't your CREATE statement terminates at the first semi-colon.
Try this:
DELIMITER $$
CREATE FUNCTION GET_HOUR_MINUTES(seconds INT)
RETURNS VARCHAR(16)
BEGIN
DECLARE result VARCHAR(16);
IF seconds >= 3600 THEN SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%kh %lm');
ELSE SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%lm');
END IF
RETURN result;
END$$
DELIMITER ;
Thanks to #Ravinder for catching the missing END IF.

Why do SQL declare fail?

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 ;

Can't create stored function - wrong syntax?

I've got the following Problem.
I want to create a stored function which converts an entity_id into the corresponding sku
Here's the code:
CREATE FUNCTION `id2sku`(`entity_id_in` INT)
RETURNS VARCHAR
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
DECLARE returnvalue varchar(50);
SELECT `sku` INTO returnvalue FROM catalog_product_entity WHERE entity_id = entity_id_in LIMIT 1;
return returnvalue;
END
Now my problem is if i fire the query i get the following message:
[Window Title]
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 'LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT' at line 3
The db im using is MySQL 5.0.51a
Thanks in advance for your ideas.
MySQL by default uses ; as a delimiter, so when it encounters the ; at line 9:
DECLARE returnvalue varchar(50);
MySQL thinks the command ends - it is trying to execute:
CREATE FUNCTION `id2sku`(`entity_id_in` INT)
RETURNS VARCHAR(50)
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
DECLARE returnvalue varchar(50);
which isn't valid SQL.
Set a new delimiter:
DELIMITER $$
CREATE FUNCTION `id2sku`(`entity_id_in` INT)
RETURNS VARCHAR(50)
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
DECLARE returnvalue varchar(50);
SELECT `sku` INTO returnvalue FROM catalog_product_entity WHERE entity_id = entity_id_in LIMIT 1;
return returnvalue;
END
$$
You can then change the delimiter back with:
DELIMITER ;
This should work:
DELIMITER $$
CREATE FUNCTION `id2sku`(`entity_id_in` INT)
RETURNS VARCHAR(50)
LANGUAGE SQL
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
DECLARE returnvalue VARCHAR(50);
SELECT `sku` INTO returnvalue FROM catalog_product_entity WHERE entity_id = entity_id_in LIMIT 1;
RETURN returnvalue;
END$$
DELIMITER ;
You had not specified the varchar length. :-)

mysql 5.1: how can i use benchmark() command to test a call to a stored procedure?

I'm trying to benchmark a stored procedure.
select benchmark(100000000,(select 1));
this benchmark works
but the following benchmark doesn't:
do benchmark(1000,(call test_login_user('a')));
it produces the following 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 'call xpofb_login_user('a')))' at line 1
any ideas how to resolve the issue ?
You can't do this with benchmark(), but you could create a stored procedure to do it.
Here's an example:
delimiter $$
create procedure benchmark_test_login_user (p_username varchar(100),
p_count int unsigned)
begin
declare v_iter int unsigned;
set v_iter = 0;
while v_iter < p_count
do
call test_login_user(p_username);
set v_iter = v_iter + 1;
end while;
end $$
delimiter ;
call benchmark_test_login_user('a',1000);
You can't
http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_benchmark
Only scalar expressions can be used. Although the expression can be a subquery, it must return a single column and at most a single row. For example, BENCHMARK(10, (SELECT * FROM t)) will fail if the table t has more than one column or more than one row.
