Error description

  • A query may return SQL0901N when the following conditions are
    satisfied:
    
    1.  The query involves a UNION (could also be via view with
    UNION or full outer join, EXCEPT or INTERCEPT which the compiler
    will generate a UNION for), and
    
    2.  At least one branch below the UNION applies a NODENUMBER or
    DBPARTITIONNUM function
    
    The following is the error stack when the SQL0901N is returned:
    sqlnn_cmpl[380]
    sqlno_exe[900]
    sqlno_planning_phase[200]
    sqlno_planning_scan[400]
    sqlno_scan_utils_qgm[200]
    sqlno_each_qur[400]
    sqlno_top_qtb[100]
    ...
    sqlno_walk_qun[100]
    sqlno_each_opr[1200]
    sqlno_plan_end_opr[1700]
    sqlno_crule_mate[100]
    sqlno_itr_plan::next[300]
    
    SQL0901N  The SQL statement or command failed because of a
    database system
    error. (Reason "sqlno_itr_plan::next      [300]:rc(-2144272209)
    No plan found.
    ".)  SQLSTATE=58004
