Regarding Performance

Hi,

I am curious to know about Left joins.At present we have less data so we are not facing any perofrmance problems.Later in the furture if we have huge data then will we have performance problems with

Left Join.if we have performance problems instead of changing them to hashing is there any way we can optimize the left joins.

I will reiterate my question .If we have performance problems with Left joins then is there any way to optimize it with out changing the codes to hashing.

I appreciate your patience and support.
