> Hi Team,
>
> Is there a configuration property to disable Tableau Probing queries.
> Sometimes it is not necessary to probe SQL statements when Tableau publish
> the reports. These queries leads confusion and some sort of syntactical
> errors / exceptions.
>
> *sample query :*
> CREATE LOCAL TEMPORARY TABLE
> "XT01_11B3408A_5074_4E96_B7A9_2D4543569E63_1_Connect" ( "COL" INTEGER ) ON
> COMMIT PRESERVE ROWS
> DROP TABLE "XT01_11B3408A_5074_4E96_B7A9_2D4543569E63_1_Connect"
> SELECT 1 AS "COL"
> SELECT TOP 1 "COL" FROM ( SELECT 1 AS "COL" ) AS "CHECKTOP"
> SELECT "COL" FROM (SELECT 1 AS "COL") AS "CHECKTOP" LIMIT 1
> SELECT "SUBCOL" AS "COL" FROM ( SELECT 1 AS "SUBCOL" ) "SUBQUERY" GROUP BY 1
> *For example below query returns error like below*
> SELECT "SUBCOL" AS "COL" FROM ( SELECT 1 AS "SUBCOL" ) "SUBQUERY" GROUP BY 1
> ERROR [http-bio-XXXX-exec-7] controller.BasicController:62
> org.apache.kylin.rest.exception.InternalErrorException: group by 1????
>
> These are *TablueTestQueries* in *QueriesUtil.java* in Utility classes
>
> Regards,
> Anilkumar.
