Select single * query will retrieve all the records from
the database table with respect to the condition specified
and finally select one single row among the retrieved.
In case of Select up to 1 row,the query starts retrieving
the database and once it gets the 1 row w.r.t its condition
it stops further retrieval.Performancewise using select
single * is not gud.
