Subj:   Performance of COUNT(Integer Constant) over COUNT(*)
 
From:   Kambhoji, Naveen Ram Prasanna

Hi All,

Is there any performance gain in COUNT(Integer Constant) over COUNT(*) ... If not so any specific use of using count(1) over count(*). How does count(*) and count(1) are calculated internally.
