Index example: Ordering and grouping on the same columns with a shared-weight sort sequence table

Ordering and grouping on the same columns with a shared-weight sort sequence table (SRTSEQ(*LANGIDSHR) LANGID(ENU)).

  SELECT JOB, SALARY FROM STAFF
   GROUP BY JOB, SALARY
   ORDER BY JOB, SALARY

When using the OPNQRYF command, specify:

OPNQRYF FILE((STAFF)) FORMAT(FORMAT3)
   GRPFLD(JOB SALARY)
   KEYFLD(JOB SALARY)
   SRTSEQ(*LANGIDSHR) LANGID(ENU) 

DB2 UDB for AS/400 could use SHRIX2 to satisfy both the grouping and ordering requirements. If index SHRIX2 did not exist, DB2 UDB for AS/400 would create an index using a sort sequence table of *LANGIDSHR.
