* Firebird and Interbase Data Provider
- ADO.NET Data Provider for Firebird and Interbase databases
- Does not exist in Mono, but is a separate project
- The Firebird Relational Database is
is an independent project which uses source code based on the Interbase source code released
by Borland under the Interbase Public License
- Both the Firebird Relational Database and the Firebird .NET Data Provider can be
downloaded from here
- The Firebird .NET Data provider has been made
available by Carlos Guzmán Álvarez (aka "Carlos G.A."), who has also made a
number of contributions to the OdbcJdbc code
- Bugs with Mono or the data provider should be reported
in Mono's Bugzilla here. If you
do not have Bugzilla user account, it is free
and easy to create one here.
** Current Status
- Current stable version: 1.0
- Current developement version: 1.5
- The new data provider/driver is written in C# and provides a high-performance native
implementation of the GDS32/API functions. This means that .Net developers
will be able to access Firebird databases without the need of Firebird
client install
- In support of the new module, a new mailing list
firebird-net-provider has
been created. Please use this list for any
questions that you may have about the provider
** New features & enhancements in 1.5 version
- Better fit to ADO.NET
- New GDS implementation
- Implicit transaction support
- Array datatype support
- Firebird services API support
- Firebird events API support
- Stored procedure calls using Sql Server style
- Support for retrieve database schema information ( FbConnection.GetDbSchema )
- Improved Commandbuilder implementation
** Testing
- Need a working mono and mcs
- Need access to a Firebird Relational Database or you can download
it from here
- Get the Firebird .NET data provider from here as
firebird-net-provider. Make
sure the Firebird .NET data provider binary assembly FirebirdSql.Data.Firebird.dll is
installed in the same place as the mono class libraries.
- Has a ConnectionString format:
"Database=databasefile.gdb;User=user;Password=pass;Dialect=3;Server=hostname"
- C# Example:
using System;
using System.Data;
using FirebirdSql.Data.Firebird;
public class Test
{
public static void Main(string[] args)
{
string connectionString =
"Database=C:\\PROGRAM FILES\\FIREBIRD\\EXAMPLES\\EMPLOYEE.GDB;" +
"User=SYSDBA;" +
"Password=masterkey;" +
"Dialect=3;" +
"Server=localhost";
IDbConnection dbcon = new FbConnection(connectionString);
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();
string sql = "SELECT * FROM employee";
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while(reader.Read()) {
object dataValue = reader.GetValue(0);
string sValue = dataValue.ToString();
Console.WriteLine("Value: " + sValue);
}
// clean up
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbcon.Close();
dbcon = null;
}
}
- Building C# Example:
- Save the example to a file, such as, TestExample.cs
- Build on Linux:
mcs TestExample.cs -r System.Data.dll \
-r FirebirdSql.Data.Firebird.dll
- Build on Windows via Cygwin:
mono C:/cygwin/home/MyHome/mono/install/bin/mcs.exe \
TestExample.cs \
-lib:C:/cygwin/home/MyHome/mono/install/lib \
-r System.Data.dll -r FirebirdSql.Data.Firebird.dll
- Running the Example:
mono TestExample.exe
