[Typo3] For my comprehension only...

[Pierre Rouwens]

Hi list,

I just wanna know why when i use 
$GLOBALS['TYPO3_DB']->exec_SELECTquery($select,$from,$where); it works 
and when i use
t3lib_DB::exec_SELECTquery($select,$from,$where); it doesn't work ... 
aren't these two ways for the same result ?

Thanks a lot for helping me to understand

Pierre
