I create a procedure. But when I try to call it I get this error message:
#1305 - PROCEDURE u941310304_menu.insert_or_update does not exist
What's wrong?
I tested you code and the call to procedure works.
Your default database is u941310304_menu, it seems you are creating the procedure in another db. You can create the procedure specifying the destination database.
DELIMITER $$
DROP PROCEDURE IF EXISTS `u941310304_menu`.`insert_or_update`$$
CREATE PROCEDURE `u941310304_menu`.insert_or_update(
[...]
If the procedure is in another database you must specify the db name as prefix:
call `another_database`.insert_or_update('sara',20,'math');

I m passing parameters in stored procedures but unable to fetch records when filtering with inputs.But when I store that Input into variables and pass it to fetch record I get the records.why?
Here is stored procedure
DELIMITER $$
DROP PROCEDURE IF EXISTS Demo_akg$$
CREATE PROCEDURE Demo_akg (IN ip_Id VARCHAR (100))
BEGIN
SELECT * FROM table_namel IAS WHERE Id = ip_Id;
END$$
DELIMITER;
I tried to take input in variable and pass it to where clause ti fetch records .
Here is the method that I have tried. And it works why?
DELIMITER $$
DROP PROCEDURE IF EXISTS Demo_akg$$
CREATE PROCEDURE Demo_akg (IN ip_Id VARCHAR (100))
BEGIN
Select ip_Id into #ip_Id;
SELECT * FROM table_namel IAS WHERE Id = #ip_Id;
END$$
DELIMITER;
We didn't know the structure of table_namel, but it seems the table have a field with same name as input parameter.
To prevent that use the parameters with some prefix/surfix:
DELIMITER $$
DROP PROCEDURE IF EXISTS Demo_akg$$
CREATE PROCEDURE Demo_akg (IN p_ip_Id VARCHAR (100))
BEGIN
SELECT * FROM table_namel IAS WHERE Id = p_ip_Id;
END$$

I have following store procedure. It is give me some error
DROP procedure IF exists getQueueMessage;
DELIMITER $$
CREATE DEFINER=`root`#`localhost` PROCEDURE `getQueueMessage`(msg varchar(100))
BEGIN
SELECT `Name` FROM queues WHERE Id IN (
SELECT PhysicalQueueId FROM indexqueuemaps WHERE ConditionFieldValue = msg)
END
END$$
DELIMITER ;
It is giving me missing semicolon error. Don't know Why this error is getting. Can someone help me?
Try like this:
DROP procedure IF exists getQueueMessage;
DELIMITER $$
CREATE DEFINER=`root`#`localhost` PROCEDURE `getQueueMessage`(msg varchar(100))
BEGIN
SELECT `Name` FROM queues WHERE Id IN (
SELECT PhysicalQueueId FROM indexqueuemaps WHERE ConditionFieldValue = msg);
END$$
DELIMITER ;
There's only one BEGIN and two ENDs, remove the 2nd END and you should be fine.
Replace root#localhost with root#localhost
I would like to execute a loop in phpmyadmin which inserts rows in a table. So far I have:
DELIMITER $$
DROP PROCEDURE IF EXISTS insert_my_rows()
CREATE PROCEDURE insert_my_rows()
BEGIN
DECLARE i INT DEFAULT 376;
WHILE i<405 DO
INSERT INTO wp_term_relationships(object_id,term_taxonomy_id,term_order) VALUES (i,16,0);
SET i=i+1;
END WHILE;
END $$
DELIMITER ;
CALL insert_my_rows()
With this, I get 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 'DELIMITER$$
DROP PROCEDURE IF EXISTS insert_my_rows()
CREATE PROCEDURE ins' at line 1
Syntax for the DROP PROCEDURE statement is incorrect!
Change
DROP PROCEDURE IF EXISTS insert_my_rows()
to
DROP PROCEDURE IF EXISTS insert_my_rows;
You need to end the statement with the proper delimiter. Change END to END$$.
You must change the delimiter only while you make blocks of statements, so during the procedure definition. The DROP PROCEDURE and CALL statements needs delimiters too.
DROP PROCEDURE IF EXISTS insert_my_rows;
DELIMITER $$
CREATE PROCEDURE insert_my_rows()
BEGIN
DECLARE i INT DEFAULT 376;
WHILE i<405 DO
INSERT INTO wp_term_relationships(object_id,term_taxonomy_id,term_order) VALUES (i,16,0);
SET i=i+1;
END WHILE;
END $$
DELIMITER ;
CALL insert_my_rows();

I have created a Stored Procedure
CREATE PROCEDURE GetAllRecords()
BEGIN
SELECT * FROM my_table;
END //
Now I want to add a parameter to this Stored Procedure like this :
CREATE PROCEDURE GetAllRecords(id1 INT(4))
BEGIN
SELECT * FROM my_table WHERE `id` = id1;
END //
How can I edit my Stored Procedure?
Delete the procedure
drop procecdure GetAllRecords//
And recreate it
CREATE PROCEDURE GetAllRecords(id1 INT(4)) ...
You have drop procedure first and then re-create it
DROP PROCEDURE IF EXISTS GetAllRecords;
CREATE PROCEDURE GetAllRecords(IN _id INT)
SELECT *
FROM my_table WHEREid = _id;
And since you're using the only statement in your procedure you can ditch BEGIN ... END block and use a usual delimiter.
In case you're wondering no you can not use ALTER PROCEDURE in this case
This statement can be used to change the characteristics of a stored
procedure. However, you cannot change the parameters or body of a
stored procedure using this statement; to make such changes, you
must drop and re-create the procedure using DROP PROCEDURE and CREATE PROCEDURE.
First of all ,This is not how you can pass the parameter in stored procedure.
You can not alter stored procedure, the way to do this is drop existing and create new one.
DELIMITER $$
DROP PROCEDURE IF EXISTS GetAllRecords$$
CREATE PROCEDURE GetAllRecords(IN param1 INT, OUT pram2 Varchar(100), INOUT param3 Date)
BEGIN
select * from <tbl>;
< Your queries>
END$$
DELIMITER ;

To Alter a stored Procedure check this link

The best way is to drop the stored proceure and create it again
DROP PROCEDURE IF EXISTS GetAllRecords
CREATE PROCEDURE GetAllRecords(IN _id INT)
AS
BEGIN
SELECT *
FROM my_table WHEREid = _id;
END
CREATE DEFINER = CURRENT_USER PROCEDURE `NewProc`(IN `pName` varchar)
BEGIN
SELECT * from ss
END;;
when I try to save this SP using navicat to MySql Db i face syntax error problem at line number 1, when i delete the parameter, SP is saved
You have to specify the length of pName in your parameter.
Try this:
DELIMITER $$
DROP PROCEDURE IF EXISTS `NewProc`$$
CREATE DEFINER = CURRENT_USER PROCEDURE `NewProc`(IN `pName` VARCHAR(100))
BEGIN
SELECT * FROM ss;
END$$
DELIMITER ;
