SQL IF Vs IIF Function
The primary distinction between
IIF functions will be discussed in this session.
SQL IF Function
The IF operator works as a short-circuiting conditional, only evaluating the true or false input based on the conditional's value.
Example 1:IF Operator
SELECT IF (5 < 6 ,'True', 'False');
Output: The result will be
The expression to evaluate in this example is 1 2 Because 1 is less than 2, the
SELECT statement was executed and the result was True.
Example 2: If the expression is false, nothing will happen.
SELECT IF (3 > 9 ,'True', 'Commands completed successfully');
Output: The result of above query is
The command was finished successfully, according to SQL Server. Because nothing else was given, nothing else was returned.
SQL IIF Function
IIF is a function that returns a value after evaluating all of its arguments.
The IIF() function is essentially a shorter version of the
IF... ELSE statement.
Example : Implement IIF Function
SELECT IIF( 3 > 4, 'Yes', 'No' );
Output: The result of above query will be
SQL DIFFERENCE BETWEEN IF AND IIF Function
Here , we discussed 5 main Conrasts in if Vs iif function mentioned in below table:-
|Type - Flow control statement.||Type - Logical function.|
|To run, you specify a SQL statement or statement block.||The actual value to return is specified.|
|The maximum number of nested levels is determined on the amount of memory available.||Only up to a maximum of 10 levels can be nested.|
||Both a true and a false value are required (i.e. you must cater for false outcomes).|
|It does not share the
||The IIF() function is really just a shortcut for writing a
