Subj:   Qualifying on encrypted passwordstring
From:   Leszek Kosinski

I am trying to use database security on a web application which sends queries to Teradata.

When a user logs on to the web application, he types his Teradata user and password. Then application logs on to the database (with an access level to system tables) in order to check whether his username and password is correct. Since password is encrypted, is it possible to apply an encrypt/decrypt function to a "where" clause and qualify on passwordstring attribute?


select username
from dbc.dbase
username = #username // variable from the interface
and passwordstring = ENCRYPT(#password) //variable from the interface

Thank you,
