DBConnection.SecondCommand

DBConnection.SecondCommand property

Specifies a second command text string that is persisted when PivotTable server-based page fields are in use. For ODBC connections, serverCommand is usually a broader query than command (no WHERE clause is present in the former). Based on these 2 commands(Command and ServerCommand), parameter UI can be populated and parameterized queries can be constructed

public override string SecondCommand { get; set; }
