IDalDriver.CreateDescriptor

Syntax

CreateDescriptor: IDalConnectionDescriptor;

Description

The CreateDescriptor method creates a description of the database connection using this driver.

Example

Executing the example requires that the repository contains a database with the BD identifier.

Add links to the Collections and Dal system assemblies.

Sub UserProc;
Var
    DBDriv: IDalOleDbDrivers;
    Driv: IDalDriver;
    ConnectDesc: IDalConnectionDescriptor;
    Params: IDalConnectionDescriptorParams;
    Params_name: IStringList;
    i: Integer;
Begin
    Params_name := New StringList.Create;
    DBDriv := New DalOleDbDrivers.Create;
    Driv := DBDriv.Driver(0);
    ConnectDesc := Driv.CreateDescriptor;
    Params := ConnectDesc.Params;
    For i := 0 To Params.Count - 1 Do
        Params_name.Add(Params.Item(i).Name);
    End For;
    i := Params.Count;
End Sub UserProc;

After executing the example the "i" variable contains the number, and the Params_name variable contains the names of all parameters that are necessary for connection using the first OLE DB driver installed in the system.
