Example

This enumeration is used by the DBProviderInfo class in the ProviderSubType property. The following example enumerates the properties of the database providers available on the computer, including the ProviderSubType which returns a value from this enumeration.

namespace dbproviderinfo
{
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            DBProviderInfos dbis = app.DBProviderInfos;
            foreach (DBProviderInfo dbi in dbis)
            {
                Console.WriteLine("Description = {0}, Name = {1}, ParseName = {2}", dbi.Description, dbi.Name, dbi.ParseName);
                Console.WriteLine("ProviderSubType ={0}, ProviderType = {1}", dbi.ProviderSubType, dbi.ProviderType);
                Console.WriteLine("SupportsNullColumns = {0}, UseFullTableName = {1}", dbi.SupportsNullColumns, dbi.UseFullTableName);
            }
        }
    }
}

Namespace dbproviderinfo
    Class Program
        Shared  Sub Main(ByVal args() As String)
            Dim app As Application =  New Application() 
            Dim dbis As DBProviderInfos =  app.DBProviderInfos 
            Dim dbi As DBProviderInfo
            For Each dbi In dbis
                Console.WriteLine("Description = {0}, Name = {1}, ParseName = {2}", dbi.Description, dbi.Name, dbi.ParseName)
                Console.WriteLine("ProviderSubType ={0}, ProviderType = {1}", dbi.ProviderSubType, dbi.ProviderType)
                Console.WriteLine("SupportsNullColumns = {0}, UseFullTableName = {1}", dbi.SupportsNullColumns, dbi.UseFullTableName)
            Next
        End Sub
    End Class
End Namespace

Sample output:

Description = MediaCatalogDB OLE DB Provider, Name = MediaCatalogDB OLE DB Provider, ParseName = {09E767A6-4481-4791-86A5-A739E5290E4C}

ProviderSubType =None, ProviderType = OleDb

SupportsNullColumns = True, UseFullTableName = True

Description = Microsoft OLE DB Provider for SQL Server, Name = SQLOLEDB, ParseName = {0C7FF16C-38E3-11d0-97AB-00C04FC2AD98}

ProviderSubType =SqlServer, ProviderType = OleDb

SupportsNullColumns = True, UseFullTableName = True
