does it means when a column has an index, the records inside will no longer
duplicate?
if so, i can't put an index to that column because that record need to be
duplicate

I want to select 1 record from 200,000 rows of records. I use this SQL
statement:
SELECT password FROM TableUser WHERE username='jack00'
It takes me about 20 seconds just to view the password.
Is there any other way to decrease the time? (In about less then 1 second)
