Subject How to login to a local database without password?
Author Ted Miglautsch
How can I attach to a local firebird database? I have a program that was
originally written for Interbase but I wanted to run it against a
firebird database. Every time it tries to connect it gets gives the error:

SQL error in Database attach:
SQLCODE = -902 IN Database attach.
SQLCODE: -902
SQL ERROR:
Unsuccessful execution caused by a system error that precludes
successful execution of subsequent statements

ISC STATUS:
-Your user name and password are not defined. Ask your database
administrator to set up a Firebird login.
Terminating...

I have no problems attaching to that same local database with isql and qli.
