PI20261: NOT REPORTING ACCESS TYPE OF NR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a SQL statement (like the one below) uses NR (Range-List
  Index Scan) as accesstype, SQLPA Explain does not provide the
  Statistics for the Index used on that accesstype or info about
  the access path used (as it does when other accesstype is used
  on the SQL statement explained).
  
     SELECT *
     FROM      SYSIBM.SYSTABLES  TB
     LEFT JOIN SYSIBM.SYSCOLDIST CD
            ON TB.CREATOR = CD.TBOWNER
           AND TB.NAME    = CD.TBNAME
     WHERE  TB.DBID  = ? AND TB.OBID = ?
        OR  TB.DBID  = ? AND TB.OBID = ?
     ;
