Hi
Thank you very much for reading my post.
can you please explain me what is differences between 1 index for one
column and one index for multiple columns ?
in both performance view and technical differences.
example :
create index Index1 on SSiteRequest (BANNERBANNERID, WEBSITESWEBSITEID,
USERSUSERID);
and
create index Index13 on SSiteRequest (USERSUSERID);
create index Index12 on SSiteRequest (WEBSITESWEBSITEID);
create index Index1 on SSiteRequest (BANNERBANNERID);
does this two kind differ from each other ?
which one will have better performance?
