Lookup ID

The error lookup service uses the lookup ID in conjunction with the return code to identify the error description, Help file, and context ID for a specific error. The lookup ID also can be a special value, IDENTIFIER_SDK_ERROR, that tells the implementation of IErrorInfo that is shipped with the data access SDK to ignore the provider's lookup service and use the description supplied in the error resource DLL shipped with the SDK.
