Answer 1

you may take this onto consideration.

1. ISNULL function required two parameters: the value to check and the replacement for null values

   2.COALESCE function works a bit different COALESCE will take any number of parameters and return the first non-NULL value , I prefer COALESCE over ISNULL 'cause meets ANSI standarts, while ISNULL does not.
