Hi,

I need to determine the version of SQL Server (2000, 2005 or 2008 in this particular case) that a connection string connects a C# console application (.NET 2.0). Can anyone provide any guidance on this?

Thanks, MagicAndi

Update

I would like to be able to determine the SQL Server version form the ADO.NET connection object if possible.

Try

Select @@version

thijs, I could use this, but was looking for an way of determining the version information from the ADO.NET connection. I will update the question accordingly.

fire this select with an ExecuteScalar and parse the result...

This code will determine the version of SQL Server database being used - 2000, 2005 or 2008:

try
{
    SqlConnection sqlConnection = new SqlConnection(connectionString);
    Microsoft.SqlServer.Management.Smo.Server server = new Microsoft.SqlServer.Management.Smo.Server(new Microsoft.SqlServer.Management.Common.ServerConnection(sqlConnection));

    switch (server.Information.Version.Major)
    {
      case 8:
        MessageBox.Show("SQL Server 2000");
        break;
      case 9:
        MessageBox.Show("SQL Server 2005");
        break;
      case 10:
        MessageBox.Show("SQL Server 2008");
       break;
      default:
        MessageBox.Show(string.Format("SQL Server {0}", server.Information.Version.Major.ToString())); 
        break;   
    }
}
catch (Microsoft.SqlServer.Management.Common.ConnectionFailureException)
{
    MessageBox.Show("Unable to connect to server",
        "Invalid Server", MessageBoxButtons.OK, MessageBoxIcon.Error);

}

The code below will do the same, this time using NinthSense's answer:

try
{    
    SqlConnection sqlConnection = new SqlConnection(connectionString);
    sqlConnection.Open();

    string serverVersion = sqlConnection.ServerVersion;
    string[] serverVersionDetails = serverVersion.Split( new string[] {"."}, StringSplitOptions.None);

    int versionNumber = int.Parse(serverVersionDetails[0]);

    switch (versionNumber)
    {
     case 8:
         MessageBox.Show("SQL Server 2000");
      break;
     case 9:
      MessageBox.Show("SQL Server 2005");
      break;
     case 10:
      MessageBox.Show("SQL Server 2008");
      break;
     default:
      MessageBox.Show(string.Format("SQL Server {0}", versionNumber.ToString()));  
      break;  
    }
}
catch (Exception ex)
{
    MessageBox.Show(string.Format("Unable to connect to server due to exception: {1}", ex.Message),
        "Invalid Connection!", MessageBoxButtons.OK, MessageBoxIcon.Error);

}
finally
{
    sqlConnection.Close();
}

Richard, excellent catch on the Smo.Server! My bad :-(

+2  A: 

Run this script from a normal SqlCommand - it's quite extensive and useful!

SELECT  
    SERVERPROPERTY('productversion') as 'Product Version', 
    SERVERPROPERTY('productlevel') as 'Patch Level',  
    SERVERPROPERTY('edition') as 'Product Edition',
    SERVERPROPERTY('buildclrversion') as 'CLR Version',
    SERVERPROPERTY('collation') as 'Default Collation',
    SERVERPROPERTY('instancename') as 'Instance',
    SERVERPROPERTY('lcid') as 'LCID',
    SERVERPROPERTY('servername') as 'Server Name'

Marc_s, Wasn't quite what I was looking for, but very useful regardless! +1

+5  A: 
SqlConnection con = new SqlConnection("Server=localhost;Database=test;user=admin;password=123456;");
con.Open();
Text = con.ServerVersion;
con.Close();

con.ServerVersion will give you:

  • 9.x.x for SQL Server 2005
  • 10.x.x for SQL Server 2008
