IF Function

Syntax

IF(expr1,expr2,expr3)

Description

If expr1 is TRUE (expr1 <> 0 and expr1 <> NULL) then IF() returns expr2; otherwise it returns expr3. IF() returns a numeric or string value, depending on the context in which it is used.

Note: There is also an IF statement which differs from theIF() function described here.

Examples

SELECT IF(1>2,2,3); +-------------+ | IF(1>2,2,3) | +-------------+ | 3 | +-------------+

SELECT IF(1<2,'yes','no'); +--------------------+ | IF(1<2,'yes','no') | +--------------------+ | yes | +--------------------+

SELECT IF(STRCMP('test','test1'),'no','yes'); +---------------------------------------+ | IF(STRCMP('test','test1'),'no','yes') | +---------------------------------------+ | no | +---------------------------------------+
