Question

I was certain there was something like a “DifferentThan” method in SQL.
I am not looking for the <> operator, which will fail NULL comparisons.

For example, imagine a nullable bit column.

When checking for “not true” I could do something like this

WHERE COALESCE(myBit,0) = 0

and perhaps this is the best way… I’m not really interested in that. I’m particularly trying to remember the syntax for something like “DIFFERENTTHAN”

WHERE myBit DIFFERENTTHAN 1

EDIT: I’ve answered my own question below.

Answer 1

The syntax is

IS [NOT] DISTINCT FROM

Which is in the ANSI standard but not included in MSSQLServer
