am not sure about it. maybe you can help me to confirm it:I wrote the SQL as followed:create
or replace view groupview asselect         usertable.username,        decode(usertable.locked,0,'Authorizers','UnAuthorizers')
as groupnamefrom        usertablewhere in the usertable there is a field named locked that
indicates whether the user is locked. so now I can allow everyone in the database to login
to the system if the user is Authorizers,and I judge the user's role.The reason I do so is
because there are existed API for doing all these and there are more than thousand users in
the database,though the userid and groupid never be the same.Now I got another problem,the
password stored in the database is encrypted,which is a common way,but the encrypting method
is not using some sql script but SHA.So,How can I parse the clear-text that  I input to SHA
password and then compare with that sto

SHA to encode it then compare it with the password stored in the database?
