Abstract
Embodiments relate to a method and computer program product for error handling. The method includes performing at least one query operation. The processing of query operation also includes generating error information data based at least an error encountered during performance of the query operation and generating a data result relating to any portion of the query operation successfully completed. The data result is processed together with the error information data based on encountering any errors. The data result and error information are provided together in a package but separated by an indicator to distinguish between them.
