Question : Select MAX(ISNULL(variable, 0)) is returning NULL when it should be returning 0

I am trying to select a value before I do an insert.

In the table, I am trying to grab the next available ID, but, it is returning NULL.  I am trying to do this:

SELECT MAX(ISNULL(fedexid, 0)) FROM fedex

Since there are no records in the FedEx table, this is returning as NULL.  How do I get the above statement to return 0 if it is NULL.

Answer : Select MAX(ISNULL(variable, 0)) is returning NULL when it should be returning 0

try

SELECT ISNULL(MAX(fedexid),0) FROM fedex
