Subj:		Does Count(*) and count(1) has any difference?

From:		Vinoth Raj Prabhakaran

Hi.

I need to perform a count of records on a huge table which is approx 80GB, based on a date condition which is not indexed. Does "SELECT COUNT(*) FROM tablenname WHERE datecolumn>1070101" and "SELECT COUNT(1) FROM tablenname WHERE datecolumn>1070101" perform the same way?.

Thanks,

Vinoth
