For more information, see IIF Function Query Hints in SQL Server Analysis Services 2008 and Execution Plans and Plan Hints for MDX IIF Function and CASE Statement. Examples The following query shows a simple use of IIF inside a calculated measure to return one of two different string values whe...
MS Access中的IIF函数是一个逻辑函数,用于根据指定的条件返回不同的结果。在IIF函数中,可以使用IN条件来判断某个值是否在一个给定的集合中。 IN条件是一个用于判断某个值是否在一个集合中的...
在SQL Server中,可以使用IIF函数来替代CASE语句。IIF函数是一个内置的逻辑函数,用于根据条件返回不同的值。 IIF函数的语法如下: IIF(condition, value_if_true, value_if_false) 其中,condition是一个逻辑表达式,如果为真,则返回value_if_true;如果为假,则返回value_if_false。 使用IIF函数可以简化复杂的CASE语句...
There are times where you need to write a single TSQL statement that is able to return different TSQL expressions based on the evaluation of another expression. When you need this kind of functionality you can use the CASE expression or IIF function to meet this requirement. In this article ...
iIF Function Posted by:Andreas Sämi Bünder Date: August 29, 2017 11:12AM Guten Abend zusammen, ich darf mich seit Jahren wieder einmal mit einer mySQL Abfrage rumschlagen, eigentlich super aber jetzt klemmt's. Ich bin in Access zuhause leider nicht in SQL. Ich muss aus 2 Tabellen die...
Thomas Kejser and I are doing some work to produce the SQL Server 2008 Analysis Services Performance Guide. Among a bunch of other things, it discusses the IIF function. But because I recently mentioned MDX query hints in a recent podcast, I wanted to get this out quickly....
The IIF logical function Returns one of two values, depending on whether the Boolean expression evaluates to true or false.
Any MDX expression can be followed by HINT LAZY which will evaluate that expression in cell-by-cell mode.EAGER and STRICT are mutually exclusive in the hint; they can be used in the same IIF(,,) over different expressions.For more information, see IIF Function Query Hints in SQL Server ...
The fact that IIF is translated into CASE also has an impact on other aspects of the behavior of this function. Since CASE expressions can be nested only up to the level of 10, IIF statements can also be nested only up to the maximum level of 10. Also, IIF is remoted to other serve...
