Answer / bharathi
No it is not a good idea. Indexes are very expensive to
maintain. Indexes are created mainly to improve performace.
If there are only 10 rows in a table, creating index would
not make any difference in the performace.

Answer / subhash
No it's not a good idea.
Table scan would be fine for smaller tables with less records. Moreover indexes need disk space. It's not necessary to create an index and waste the disk space.
