Replace function set as Store Procedure or Function in MySQL?

Question

How can I convert my replace function as a stored procedure or function in MySQL?

Here is a simplified update script:

mysql> UPDATE content SET url = REPLACE (url, 'testsite', 'livesite') WHERE URL LIKE '%testsite%';

I want to be able to store this and run this function via a query.

My goal is to to something like this:

CALL myupdatefunction ('testsite', 'livesite', @url);

This is what I have tried so far:

DELIMITER //
CREATE PROCEDURE updateURL(OUT url1, OUT url2)
BEGIN 
   UPDATE content SET url = REPLACE (url, url1, url2) WHERE URL LIKE url1;
END //
DELIMITER ;

And to CALL

CALL updateURL('stringOld','stringNew');

Not sure if this is the right approach?

Answer 1

You just have to make a little change, you have to add the percent sign in the like expression

DELIMITER //
CREATE PROCEDURE updateURL(OUT url1, OUT url2)
BEGIN 
   UPDATE content SET url = REPLACE (url, url1, url2) WHERE URL LIKE CONCAT('%', url1, '%');
END //
DELIMITER ;
