Paul Rogers commented on DRILL-4673:
------------------------------------
>From user mailing list from Vitalii:
I'm going to implement "DROP TABLE IIF EXISTS" and "DROP VIEW IIF EXISTS"
statements in Drill. The reason of using "IIF" is inability of adding "IF"
keyword to non-reserved words list (due to SQL:2011 standard which calcite
parser uses). Adding of "IF" to reserved words list leads to not working hive
"IF" UDF.
I'm interested are there any concerns with using "IIF"?
