MySQL query - Invalid Use of Group Function - Using SUM -


i having "invalid use of group function" error while executing following query.

select id, faultdistribution, faulttype, faultseverity,  sum(if (faultdistribution='crs', sum(if(faultdistribution='crs',1,0))*8, 0)+ if (faultdistribution='configuration', sum(if(faultdistribution='configuration',1,0))* 6, 0)+ if (faulttype='business' , faultseverity='fatal', sum(if(faulttype='business' , faultseverity='fatal',1,0))* 4, 0)+ if (faulttype='business' , faultseverity='major', sum(if(faulttype='business' , faultseverity='major',1,0))* 2, 0)+ if (faulttype='business' , faultseverity='moderate', sum(if(faulttype='business' , faultseverity='moderate',1,0))* 5, 0)+ if (faulttype='business' , faultseverity='minor', sum(if(faulttype='business' , faultseverity='minor',1,0))* 3, 0)+ if (faulttype='look & feel' , faultseverity='fatal', sum(if(faulttype='look & feel' , faultseverity='fatal',1,0))* 2, 0)+ if (faulttype='look & feel' , faultseverity='major', sum(if(faulttype='look & feel' , faultseverity='major',1,0))* 1, 0)) tbl_fault product='das' , faultdistribution='missed'

where doing wrong? kindly help!

sum(), count(), avg(), min(), max(), etc. aggregate functions requires specify group by, unless you're using them on every column in select-list.

in case, query should work adding following @ bottom:

group id, faultdistribution, faulttype, faultseverity

...but judging many nested if's have, i'm not entirely sure give output you're looking for.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
