Symptoms
OBIEE 12c - Impala - Nested TIMESTAMPADD,TIMESTAMPDIFF does not get submitted in the physical query
After installing the <Patch 26437161> - IMPALA TRIM AND TIMESTAMPADD,TIMESTAMPDIFF ISSUE, the nested timestampadd functions does not get propagated/submitted in the physical SQL to the DB.
For example TimeStampAdd(SQL_TSI_MONTH, -12, Current_Date) gets submitted as add_months('2017-09-26', -12) but TimeStampAdd(SQL_TSI_DAY,-(DayOfMonth(Current_Date)), TimeStampAdd(SQL_TSI_MONTH, -12, Current_Date)) does not show up on the physical SQL.
Nested timestampadds are supported with Oracle as a DB, the function gets translated and gets pushed down to the DB in the SQL.
