CONCAT'ing NULL fields

Question

I have a table with three fields, FirstName, LastName and Email.

Here\'s some dummy data:

FirstName | LastName | Email
Adam        West       adam@west.c         


        

Answer 1

Try

ISNULL(FirstName, '') -- In SQL Server
IFNULL(Firstname, '') -- In MySQL

So,

CONCAT(ISNULL(FirstName,''),ISNULL(LastName,''),ISNULL(Email,'')) -- In SQL Server
CONCAT(IFNULL(FirstName,''),IFNULL(LastName,''),IFNULL(Email,'')) -- In MySQL

would return the same thing without the null issue (and a blank string where nulls should be).
