ERROR when send table as parameter in MySQL store procedure - mysql

I wrote a store procedure. It executes properly, but when I call the procedure, it shows the error:
Error Code : 1327 Undeclared variable:
Third
Please see my procedure below:
DELIMITER $$
USE `db_test`$$
DROP PROCEDURE IF EXISTS `test_proc`$$
CREATE DEFINER=`root`#`localhost` PROCEDURE `test_proc`(IN newsInfoTable VARCHAR(100))
BEGIN
SET #sql_stam = CONCAT('SELECT news INTO ', #news,' FROM ',newsInfoTable,' WHERE ',CURDATE(),'=?;');
PREPARE s1 FROM #sql_stam;
SET #where_param = DATE_FORMAT(date_time,'%Y-%m-%d');
EXECUTE s1 USING #where_param;
SELECT #news;
END$$
DELIMITER ;
Calling parameter:
USE db_test;
CALL test_proc('tbl_morning_news');


Change your code into:
DELIMITER $$
USE `db_test`$$
DROP PROCEDURE IF EXISTS `test_proc`$$
CREATE DEFINER=`root`#`localhost` PROCEDURE `test_proc`(IN newsInfoTable VARCHAR(100))
BEGIN
SET #sql_stam = CONCAT( 'SELECT news INTO #news FROM ',newsInfoTable
,' WHERE DATE(`date_time`) = CURDATE()' );
PREPARE s1 FROM #sql_stam;
SELECT #news;
END$$
DELIMITER ;

mysql stored procedure error: missing semicolon

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

Stored Procedure using Select Error 1064

I have a simple procedure to select data from an column and show them
DELIMITER //
DROP PROCEDURE IF EXISTS `testing`
CREATE PROCEDURE `testing`(IN param1 VARCHAR(40))
BEGIN
SELECT * FROM testingdatabase,
END //
DELIMITER;
However I keep getting error 1064

SELECT * FROM testingdatabase;
use ; not ,
So it should be:
DELIMITER //
DROP PROCEDURE IF EXISTS `testing`//
CREATE PROCEDURE `testing`(IN param1 VARCHAR(40))
BEGIN
SELECT * FROM testingdatabase;
END //
DELIMITER ;

DELIMITER //
DROP PROCEDURE IF EXISTS `testing`//
CREATE PROCEDURE `testing`(IN param1 VARCHAR(40))
BEGIN
SELECT * FROM testingdatabase;
END //
DELIMITER ;

DELIMITER //
DROP PROCEDURE IF EXISTS testing//
CREATE PROCEDURE testing(IN param1 VARCHAR(40)) BEGIN
SELECT * FROM testingdatabase;
END //
DELIMITER ;

Check this
DELIMITER $$
CREATE
PROCEDURE `testing`(IN param1 VARCHAR(40))
BEGIN
SELECT * FROM `test_table` WHERE `test_cdeo` LIKE param1;
END$$
DELIMITER ;
You can call and check your procedure via sql command like below code
CALL testing('149514')

MySQl navicat :: Error in adding parameters

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 ;

mysql query help (like statement)

I am using mysql which i have a stored procedure which has an input variable.
I want to use this variable in a select statement (with like clause).
Eg:
DELIMITER $$
DROP PROCEDURE IF EXISTS `DeleteDataByTransactionID` $$
CREATE DEFINER=`root`#`%` PROCEDURE `DeleteDataByTransactionID`(in **$TransactionID** varchar(50))
BEGIN
delete from sqlstatements where tempsql like '%'+ **$TransactionID** + '%';
END $$
DELIMITER ;
Thanks

DELIMITER $$
DROP PROCEDURE IF EXISTS `DeleteDataByTransactionID`
$$
CREATE DEFINER=`root`#`%` PROCEDURE `DeleteDataByTransactionID`(TransactionID VARCHAR(50))
BEGIN
DELETE
FROM sqlstatements
WHERE tempsql LIKE CONCAT('%', TransactionID, '%');
END
$$
DELIMITER ;

Actually, the accepted answer's version is open to SQL injection if the caller does not properly parameterize the call to the stored procedure. I would recommend utilizing a prepared statement in the stored procedure as follows to be safe instead of relying on the caller:
DELIMITER $$
CREATE PROCEDURE `DeleteDataByTransactionID`
(
TransactionID VARCHAR(50)
)
BEGIN
SET #sql =
"DELETE
FROM sqlstatements
WHERE
tempsql LIKE CONCAT('%', ?, '%')";
SET #transid = TransactionID;
PREPARE stmt FROM #sql;
EXECUTE stmt USING #transid;
DEALLOCATE PREPARE stmt;
END
