Username and password are not defined

[aim22]

i'm really new using Interbase/Firebird... im developing an application on Delphi 7, using MDO components and everything goes well except that sometimes after i do an update on a table using the application it tells me my username and password are not defined.

im using the defaults SYSDBA, masterkey. It only lets me log in again after i reboot.

You first have to look into your Interbase Log files - maybe your database is not active anymore for some reason.

If all seems to be good, you will have to put traces into your application -- seems to be "disconnected" or something like that (not sure). Your query seems to point on a closed database: so look for duplicate instance of your datamodule (if you are using one)
