Hello Dave,
As far as I research, there are three override GetSchema methods of the
ODBCConnection. They are documented in the following
OdbcConnection.GetSchema(),
http://msdn.microsoft.com/en-us/library/ms135851.aspx
OdbcConnection.GetSchema(String),
http://msdn.microsoft.com/en-us/library/ms135852.aspx
OdbcConnection.GetSchema(String, String[]),
http://msdn.microsoft.com/en-us/library/ms135853.aspx.
I think we can use the reflector to see what caller/callee relations are
there in these three GetSchema methods. The following disassembly codes are
got from the reflector,
public override DataTable GetSchema()
{
return this.GetSchema(DbMetaDataCollectionNames.MetaDataCollections,
null);
}
public override DataTable GetSchema(string collectionName)
{
return this.GetSchema(collectionName, null);
}
public override DataTable GetSchema(string collectionName, string[]
restrictionValues)
{
ExecutePermission.Demand();
return this.InnerConnection.GetSchema(this.ConnectionFactory,
this.PoolGroup, this, collectionName, restrictionValues);
}
The first and second GetSchema method calls into the GetSchema(String,
String[]). And they all goes into the InnerConnection's GetSchema() method.
Are these you want?
