[Firebird-net-provider] Dynamic SQL Error -901 Feature is not supported

[Michael S. <mic...@on...>]

Hi,
i have read an article in this newsgroup about a problem in executing an
SQL-Query. I have exactly the same problem, but unfortunately there was no
solution posted. So i will make a new attempt.
Im using VC# with .NET Vers. 1.1 and try to execute an SQL-Query via the
.NET-Provider for Firebird 1.6.2. The Database resides on a remote Windows
PC and is connected via NetBEUI. I'm able to succesfully test the
connection, but i cannot execute any kind of SQL-Command. I always get the
same Error Code: "Dynamic SQL Error; SQL Error Code = -901; Feature is not
supported." In Fact i get this error message if i use ANYTHING as the
Commandstring, even if it doesn't resemble SQL at all.
Some Further Information: It is possible to execute the queries using the
odbc-Provider on the same Database. I also noticed the following: when i use
the CommandTextEditor which is integrated in PropertiesPage of an
FbCommand-Object, the same error message returns, but the whitespaces in the
error message are not correctly interpreted. Charset?

Here's some code which doesn't execute:


//Created a Connection 'Verbindung'
Verbindung.Open();
string sqlCom = "Select * from RECHNER";
FbCommand Kommando = new FbCommand(sqlCom, Verbindung);
//The following Statement raises Error -901
FbDataReader Reader = Kommando.ExecuteReader();
//Using the Reader


It's certainly all the same if i use a dataAdapter instead. I'm quite new to
DB-Programing, so it might be something very dumb, nevertheless i would be
glad if s.o. could help with that.

Thanks in Advance

Michael
