Hi Cosmin,
Hopefully I didn't miss the point of your question, but is there a
reason you can't just say
X := FbCommand.Create('SELECT * FROM TAB WHERE ID=''7''', Connection,
Transaction);
(not the use of the double "'" around the thing you are looking for).
I use Firebird quite extensively in a number of C# projects, and in the
beginning I battled with parameters too. Now it doesn't appear as if
they are often necessary as long as you "quote" your values and criteria
properly.
Hope that helps?
John.
