IKeyParams Interface

IKeyParams lists the names and values of the fields a dataset adapter uses to uniquely identify database records.

Pascal

C++

__interface IKeyParams;

Description

Dataset adapters (TDataSetAdapter) use this interface internally to read the field values that uniquely identify database records. IKeyParams introduces two properties, Names and Values, that represent the names of dataset fields and the corresponding values on a desired record. The set of names and values obtained from this interface identify a single database record.

Note: Method declarations that use IKeyParams use the _di_IKeyParams type instead. This type is a DelphiInterface wrapper around the IKeyParams interface:

typedef System:: DelphiInterface < IKeyParams > _di_IKeyParams;
