Subject Tableau / filter issues
Date Mon, 17 Aug 2015 15:02:07 GMT
Hello Driller,
I'm facing issues using the Filter function of Tableau with Drill : Tableau always populates
values of the filter with "null".The action is translated into 2 queries within Drill :
SELECT * FROM (SELECT field FROM Table GROUP BY field ORDER BY field ASC) T LIMIT 0 
SELECT field FROM Table GROUP BY field ORDER BY field ASC
It seems that Tableau is fetching the result of the first query (null - which seems to by
generated to catch exceptions) instead of the second one.
Anyone already met this issue ? Is there a workaround or customization parameter to ajust
?
conf : Tableau v9.0 + MapRDrillODBC driver with TDC file deployedDrill V1.1.0
