Hive Functions via ODBC Driver (QlikView)

Hi,

I'm having some trouble executing function-based Hive queries in QlikView (ODBC connector parse error), and I'm looking to understand if the fault lies in the QV syntax, or if functions are simply not supported by the Hive ODBC driver.

Example...

The following works in Hive command line:

select distinct a_date, reverse(a_date) from a_table where a_date > '20151201';

The following fails in QV:

SQL SELECT 
	reverse("a_date")
FROM HIVE.a_db."a_table"
WHERE "a_date" > '20151201';

The QV and connector implementation is fine otherwise; substituting 'reverse' with 'max' executes happily.

Thanks,

J.

@Joanna Waligora are you still having issues with this? Can you accept best answer or provide your own solution?

The QV support team is currently investigating this problem. I will provide an update / closure once I receive their feedback.

Also, I want to correct my initial statement - max, and length functions work fine, but reverse, instr, and regexp_extract don't.
