Retrieves a TOraLob object for a field with known name.
function GetLobLocator(const FieldName: string): TOraLob;
Call the GetLobLocator method to retrieve a TOraLob object for a field when only its name is known. FieldName is the name of an existing field. The field should have the ftOraClob or ftOraBlob type.
Note: GetLobLocator is an obsolete method. In newer projects call GetLob instead.
