what is meant by sql injection with example and one more question how to catch the errors in sqlse..

Answer / sudheer

sql injection attacks are used to steal information from a
database from which normally not be available and /or to
gain access to an organaization 's host computers through
the computer that is hosting the database.
EXAMPLE:
select email,pwd,login_id,fullname from members where
email='x'

Now somebody does not put 'x' as the input but
puts 'x ;drop table members;' so the actual sql wich will
execute is
select email,pwd,login_id,fullname from members where
email=x;drop table members;
Think once what happens to ur database.
