ISNULL function

[ram krishna]

In a program, I work with SQLServer and MySql. In a particular select,
for SQLServer, I have something like this:

SELECT ISNULL(field,0) FROM TABLE.

If the field is not null, returns its value; otherwise, 0.

I have found isnull for MySQL, but it does not work exactly the same
way.

Any idea to convert that isnull from SQLServer to MySQL?

This is how i use in MSSql:-

fieldname = "ISNULL(Max(iClientID),0)+1"
ClientID = Convert.ToInt32(obj.ReturnSingleValue("UserClient", fieldname))

So in mysql ,what is its equivalent?
