dbExpress "database unavailable"

Recommended Posts



I finally manage to success a TSQLConnection with all the required params.

Before i run my program i test it and change the connection from false to true.

Add the password and it connects successfully.

Return to True to False propertie.

Try to run my program and i get the below message




Am i doing something wrong or embarcadero have some default about dbexpress components and make me drive crazy?

After many tries  and a lot of read i found that the dbExpress components simple aren't to stable.

So i change to FireDac and everything works just fine.

So please do not use dbExpress components at least for Interbase Database embedded.


Thank you for all the awnsers.
