PH34873: OFFLOADING QUERY USING CAST OF DATE TIME VALUE WILL ALWAYS RETURN THE RESULT IN ISO AND NOT AS DEFINED IN DSNHDECP, E.G. EUR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Offloading a query to IBM DB2 ANALYTICS ACCELERATOR V7 using CAS
  T of DATE or TIME value does return the result always in ISO reg
  ardless if DSNHDECP DATE TIME VALUE is different. E.g. HDEPC DAT
  E TIME EUR return from IDAA always as ISO.
  Sample of incorrout:
  SELECT CAST(DATE(current timestamp)    AS CHAR(10))
     FROM sysibm.sysdummy1  with ur ;
  ==> 2021/02/26  instead if EUR as set in HDECP 26.02.2021.
  

Local fix

• Change:
  SELECT CAST(DATE(current timestamp)    AS CHAR(10))
     FROM sysibm.sysdummy1  with ur ;
  to
  SELECT CHAR(DATE(CURRENT TIMESTAMP),EUR)
     FROM sysibm.sysdummy1  with ur ;
