Information in Error Interfaces
The SQL Server Native Client OLE DB provider reports some error and status information in the OLE DB-defined error interfaces IErrorInfo, IErrorRecords, and ISQLErrorInfo.
The SQL Server Native Client OLE DB provider supports IErrorInfo member functions as follows.
| Member function | Description |
|---|---|
| GetDescription | Descriptive error message string. |
| GetGUID | GUID of the interface that defined the error. |
| GetHelpContext | Not supported. Always returns zero. |
| GetHelpFile | Not supported. Always returns NULL. |
| GetSource | String "Microsoft SQL Server Native Client". |
The SQL Server Native Client OLE DB provider supports consumer-available IErrorRecords member functions as follows.
| Member function | Description |
|---|---|
| GetBasicErrorInfo | Fills an ERRORINFO structure with basic information about an error. An ERRORINFO structure contains members that identify the HRESULT return value for the error, and the provider and interface to which the error applies. |
| GetCustomErrorObject | Returns a reference on interfaces ISQLErrorInfo, and ISQLServerErrorInfo. |
| GetErrorInfo | Returns a reference on an IErrorInfo interface. |
| GetErrorParameters | The SQL Server Native Client OLE DB provider does not return parameters to the consumer through GetErrorParameters. |
| GetRecordCount | Count of error records available. |
The SQL Server Native Client OLE DB provider supports ISQLErrorInfo::GetSQLInfo parameters as follows.
| Parameter | Description |
|---|---|
| pbstrSQLState | Returns a SQLSTATE value for the error. SQLSTATE values are defined in the SQL-92, ODBC and ISO SQL, and API specifications. Neither SQL Server nor the SQL Server Native Client OLE DB provider defined implementation-specific SQLSTATE values. |
| plNativeError | Returns the SQL Server error number from master.dbo.sysmessages when available. Native errors are available after a successful attempt to initialize a SQL Server Native Client OLE DB provider data source. Prior to the attempt, the SQL Server Native Client OLE DB provider always returns zero. |
