Answer / nawazish sultan
In sql server 2005 we create 250 indexes (1 clustered + 249
non clustered) where as in sql server 2008 it 999.
It is not a best practice to create indexes on all the
columns.Create index on whichever it is necessary becoz it
wont affect too much on DRL but it will obviously slowdown
the DML operation.

Answer / surendra
we can create number of indexes we want but these are useful to us to speed up the retreive the records
such as these columns are simultaneously used in where clause
when we create more indexes that are not necessary to us at that time the performance is definitely decreased.
so, create indexes depends upon the usage.
