in that case only think i can understand is you need to ask your api provider to give old password on load and when a user type current password you can match lenth string and everything on spot using javascript .. that could i understand from your question

1. Set @Vsupwd = (select Password from user where id = @id)
4. If @Pcurrentpassword = @Vsupwd
5. Begin
7. Update [dbo].[user] Set [Password] = @Pnewpassword Where Id = @id
9. end
