Summary: in this tutorial, you will learn how to use the SQL Server IIF () function to add if-else logic to queries.

Introduction to SQL Server IIF () function. The IIF () function accepts three arguments. We can consider the Sql Server IIF as the shorthand way of writing IF Else, and CASE statements. The function IIF returns one of values depends of the evaluation of an expression.

This is not a standard SQL function and exist for compatible with MS Access. IIF statement with multiple conditions. Służą one do tworzenia tak zwanych instrukcji warunkowych – czym one są oraz jak ich użyć opowiem w dalszej części niniejszej.

It is a shorthand form of writing CASE statement logic or IF-ELSE logic. We explored Case Statement in SQL in my earlier article. We use a case statement to return a result based on the defined condition.

The Institute of International Finance is the global association of the financial industry, with close to 4members from countries. The behavior of function IIF() is quite similar to CASE and IF statements in SQL Server.

Using IIF(), you can use fewer lines of code, and your code will be more readable. Let’s explore the IIF() function with some examples. IIF (Con Result Result2) is a shortcut for “ CASE WHEN Cond THEN ResultELSE ResultEND ”. Web page addresses and e-mail addresses turn into links automatically. Lines and paragraphs break automatically. For example: Dim x As Boolean = True Dim result = IIf (x = True, DoSomething DoSomething2) This calls both DoSomethingand DoSomething event if x = True.

Sin embargo CASE es uno de los comandos más poderosos en el lenguaje Transact-SQL. En contraste con sentencias IF IIF, por su puesto!
