Question: I have problems with paths to the database when I use Firebird Embedded at run-time and Firebird at design-time. Can you give me some advice?
Answer: We have consulted with Dmitry Emanov about Firebird Embedded and now we can tell you about possible problems with it.
1. You can not use Firebird or Yaffil Embedded in the debug-mode. The debug-mode allows a single connection to a database; when you try to navigate through your application step-by-step using Delphi debugger it tries to create two connections.
2. If you use related paths to a database (without absolute paths) at design-time you can not be sure that Delphi IDE considers a directory with your current project as default. That's why Firebird (and Yaffil) Embedded sometimes can not find your database file.
Dmitry Emanov recommends to use Firebird SS for development and Firebird Embeddded for distribution. Since the embedded server exclusively locks the database file, it's impossible to access a database from different applications using fbembed.dll. That's exactly the case with Delphi, if your datasets are open in the design-mode and you're running your application under debugger. Just small correction - the embedded server does support multiple connections if they're being established from the single parent process (in different threads).

What a good job you did! Keep coding great pieces of fast and efficient software:) We started using FIBPlus back in 2001. Since then, every project we offer uses FIBPlus to connect to FirebirdSQL. You library has always been stable, flexible and rocket fast ! Our major project, an helpdesk/data mining application, concurrently used daily by more that a hundred technicians and analysts, uses FIBPlus. Now that FirebirdSQL 2.0 is available, we have been able to upgrade our application quickly and painlessly - that's another reason you can be proud of your work ! >>
