how to pass parameter to stored procedure using mysql

Im trying to add parameter to this stored procedure
DELIMITER $$
DROP PROCEDURE IF EXISTS `mifostenant-default`.`test` $$
CREATE PROCEDURE `mifostenant-default`.`test` ()
BEGIN
select * from employees
END $$
DELIMITER ;

Here is the way to make a procedure and pass a parameter to it:
delimiter $$
DROP PROCEDURE IF EXISTS `mifostenant-default`.`test`;
CREATE PROCEDURE `mifostenant-default`.`test` (IN empName CHAR(20))
BEGIN
SELECT * FROM employees WHERE employee_name=empName;
END $$
delimiter ;
And you call your procedure as below:
CALL mifostenant-default.test(the_parameter_to_pass);

Mysql simple stored procedure syntax error

I write a simple mysql stored procedure in workbench, however, it complains syntax error. What is wrong with my syntax?
CREATE DEFINER=`root`#`localhost` PROCEDURE `SelectIndicatorsByExistReferenceID`()
BEGIN
select * from indicators;
END

Check out this link for a simple example of a Stored Procedure.
To your question: When you define a SP, you always start with setting a new delimiter in order to use the normal delimiter (;) in your SP. If you don't do this, SQL thinks that you finished your query after the smicolon, which isn't at the end of your query so it throws an error. To set a new delimiter, do the following:
DELIMITER //
CREATE DEFINER=`root`#`localhost` PROCEDURE `SelectIndicatorsByExistReferenceID`()
BEGIN
SELECT * FROM indicators;
...
END //
DELIMITER ;
So now, you first set the delimiter to // and sql just stores the simicolons in your SP. At the END, you say that your query is done and type // - the new delimiter. Then you set it back to the normal simicolon in order to continue as always.

You'd better post your error messages, even though I can guess the problem you are suffering.
The default delimiter of MySQL is ";". So MySQL Workbench treat the statement below as a complete statement:
CREATE DEFINER=`root`#`localhost` PROCEDURE `SelectIndicatorsByExistReferenceID`()
BEGIN
select * from indicators;
It's definitely wrong!
So you should change the delimiter expilictly when you write procedures. Here is an example:
delimiter // -- change the delimiter temporarily
CREATE DEFINER=`root`#`localhost` PROCEDURE `SelectIndicatorsByExistReferenceID`()
BEGIN
select * from indicators;
END //
delimiter ; -- restore the default delimiter

DELIMITER $$
CREATE DEFINER=`root`#`locahost` PROCEDURE `SelectIndicatorsByExistReferenceID`()
BEGIN
SELECT * from indicators;
END $$
DELIMITER ;

Use this
DELIMITER $$
CREATE DEFINER=`root`#`locahost` PROCEDURE `SelectIndicatorsByExistReferenceID`()
BEGIN
SELECT * from indicators;
END $$
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')

ERROR when send table as parameter in MySQL store procedure

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 ;
