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. :-)

I ask because I don't know where is the error.
I need to create a function in MySQL. I'm using PhpMyAdmin.
CREATE FUNCTION `aggiungiPermesso`(matricolaUtenteLoggato VARCHAR(20),nomeNuovoPermesso VARCHAR(20),descrizioneNuovoPermesso VARCHAR(250)) RETURNS VARCHAR(150)
BEGIN
DECLARE hapermesso INT;
SELECT COUNT(*) INTO hapermesso FROM ottiene WHERE matricolaUtenteLoggato = ottiene.Matricola AND ID =(SELECT id FROM permesso WHERE Nome = 'Aggiungi permesso')
IF(hapermesso < 1) BEGIN
RETURN 'Errore. Non hai i permessi.';
END
INSERT INTO `permesso`(`ID`,`Nome`, `Descizione`) VALUES(0,nomeNuovoPermesso,descrizioneNuovoPermesso) RETURN 'Nuova operazione aggiunta con successo.';
END
DELIMITER;
The error is
#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
What is the error?
The error was because you were using wrong syntax for Return and IF. I have corrected your query and it works fine now.
DELIMITER $$
CREATE FUNCTION `aggiungiPermesso`(matricolaUtenteLoggato VARCHAR(20),nomeNuovoPermesso VARCHAR(20),descrizioneNuovoPermesso VARCHAR(250)) RETURNS VARCHAR(150) CHARSET latin1
BEGIN
DECLARE hapermesso INT;
SELECT COUNT(*) INTO hapermesso FROM ottiene
WHERE matricolaUtenteLoggato = ottiene.Matricola AND ID =(SELECT id FROM permesso WHERE Nome = 'Aggiungi permesso');
BEGIN RETURN IF(hapermesso > 1,'Errore. Non hai i permessi.','None');
END;
INSERT INTO `permesso`(`ID`,`Nome`, `Descizione`)
VALUES(0,nomeNuovoPermesso,descrizioneNuovoPermesso);
RETURN 'Nuova operazione aggiunta con successo.';

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've written a function but it gives me mistake a the second line (create statement) if anyone could help me, I really appreciate:
CREATE FUNCTION GetPrefix (phone_num VARCHAR(30)) RETURNS varchar(30)
deterministic
BEGIN
DECLARE x INT;
DECLARE prefix varchar(30);
SET x = 0;
for prefix in SELECT code
FROM tab_len
while (length(phone_num)) > 0
do
if prefix<>left(phone_num, length(phone_num)-x)
then set x=x+1 ;
else return 1 ;
END while ;
END $$;
and I receive this error :
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'for prefix in SELECT code
FROM tab_len while (length(phone_n' at line 9
DELIMITER $$
DROP FUNCTION IF EXISTS GetPrefix $$
CREATE FUNCTION GetPrefix
(
phone_num VARCHAR(30)
)
RETURNS varchar(30)
BEGIN
DECLARE var_x INT DEFAULT 0;
DECLARE var_prefix VARCHAR(100);
SET phone_num = IFNULL(phone_num,'');
-- your logic will go here.
return phone_num;
END$$
DELIMITER ;
SELECT GetPrefix('test');
This is right syntax to write a function in mysql.
check out the differences. Take a look Here
I am trying to create a function that returns rowcount. But it returns error again and again.

Most probably your version of PHPMyAdmin does not support the DELIMITER statement which is not MySQL statement. Here you can find how to create the function in PHPMyAdmin: Store procedures in phpMyAdmin
Yes. This was helpfull
I have created the solution:
DELIMITER $$

DECLARE var_name INT;

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"
