How to pass a variable to a IN clause?

Question

Lets say I have a SP that has a SELECT statements as follows,

SELECT product_id, product_price FROM product 
WHERE product_type IN (\'AA\',\'BB\         


        

Answer 1

Pass parameter value like this - 'AA,BB,CC'. Then, it is enough to use FIND_IN_SET function -

SELECT product_id, product_price
FROM product
WHERE FIND_IN_SET(product_type, param);

Answer 2

Try using a prepared statement: http://dev.mysql.com/doc/refman/5.5/en/sql-syntax-prepared-statements.html

Answer 3

passing a string using a variable was a problem assume this solution

DELIMITER $$

CREATE DEFINER=`root`@`localhost` PROCEDURE `spTestListValues`(_list varchar(200))
BEGIN
        SET @LIST=_list; -- assume this a paramter from the stored procedure
    SELECT NULL AS Id,  '' AS Description --insert null value to be used for list box population
    UNION  
    (SELECT id, Description
    FROM test_table
    WHERE FIND_IN_SET(id,@LIST) ORDER BY Description ASC) ;

END

Calling the procedure from other query window

call `spTestListValues`('4,5,3'); --no paramter currently for test

output

ID Description
NUll 
1   TEST1 
4   TEST2
5   TEST3

Answer 4

create a user-defined function that will convert the comma separated value into table, and by join this two can get the desired result.
