Hi,
I was looking for something like this.
InMssql when I use a query like selece a,b from some table where
a.x=b.y,then if a is having say 30000 records and b is having 4 records then
it will compare all the 30000 records with the 4 records one by one,but if I
make it where b.y=a.x then it will be faster.
I know with index I could increase the performance by 50 %,but what other
possibilities are there to improve the performance
