IF Function




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 the IF() function described here.


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                                    |
