Default Concatination

I have a query that selects fields from the database and places a seperator between each field. For example:

SELECT Concat_WS(",",Firstname,MI,Lastname) From Customers

The problem is that if MI is blank it does not write a comma signifying that there is another field that does not contain any data. Is there a way to solve this?

Try this.

SELECT Concat_WS(",",Firstname,Replace(MI,NULL,'NULL'),Lastname) From Customers
SELECT Concat_WS(",",Firstname,Replace(MI,NULL,''),Lastname) From Customers
