Also asked, what is the difference between IF and IIF?

The critical difference between IIF (available from VS 2002 forward) and IF (available in VS 2005 forward) is that IIF is a function and evaluates all of its arguments prior to returning a value, while IF is an operator that executes like a short-circuiting conditional, only evaluating the true or false argument

is true SQL Server? SQL Server does not have literal true or false values. You'll need to use the 1=1 method (or similar) in the rare cases this is needed. You can use the values 'TRUE' and 'FALSE' . The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.

Likewise, people ask, what is the use of Nullif in SQL?

In SQL Server (Transact-SQL), the NULLIF function compares expression1 and expression2. If expression1 and expression2 are equal, the NULLIF function returns NULL. Otherwise, it returns the first expression which is expression1.

What is the IIF function?

In computing, IIf (an abbreviation for Immediate if) is a function in several editions of the Visual Basic programming language and ColdFusion Markup Language (CFML), and on spreadsheets that returns the second or third parameter based on the evaluation of the first parameter.
