    TABLES
    AND PLAN HAS IUD LOLEPOP ON AN INNER OF ROWSTORE NLJN AND THE
    INNER IS MORE COMPLEX THEN JUST CDE OPERATION,
    AND WE NEED TO IUD MORE THEN ONE ROW,  THEN THE TRAP WITH THE
    FOLLOWING STACK IS POSSIBLE:
    
          cdeInterface::getPRT
          sqlriCdeFastUpdate
          sqlriSectInvoke
          sqlrr_dss_router
          sqlrr_subagent_router
    
    delete could trap with the following stack:
    sqloEDUCodeTrapHandler
    cdeTableAccessorInterface::deleteRow
    cdeInterface::performDelete
    sqlriCdeFastDelete
    sqlriSectInvoke

  • Try to force a different plan, one that does not have a rowstore
    NLJN above an IUD operation.
