> Dear all,
> I'm facing a very critical problem. When I use Tableau 10.5 with Kylin 2.1.0, the Tableau Server will send many SQL with "{fn CURRENT_DATE()}" via ODBC Driver(2.1.0), and the Kylin Server 2.1.0 will parse the CURRENT_DATE() to "2018-07-20 00:00:00"(the real current date). the logs are as below
> {noformat}
> Query Id: 14e7b152-6be0-4539-8fd0-c28bbffa6b25
> SQL: SELECT "APP_DAILY_ACTIVE_USER_PROPERTY_DI"."AV" AS "AV",
> COUNT(DISTINCT "APP_DAILY_ACTIVE_USER_PROPERTY_DI"."MC") AS "usr_Calculation_267682710052360192_ok"
> FROM "ADL"."APP_DAILY_ACTIVE_USER_PROPERTY_DI" "APP_DAILY_ACTIVE_USER_PROPERTY_DI"
> LEFT JOIN "DIM"."APP" "APP" ON ("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."AC" = "APP"."ID")
> INNER JOIN "DIM"."CALENDAR" "CALENDAR" ON ("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."ACTION_DT" = "CALENDAR"."CAL_DT")
> WHERE ((CAST("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."ACTION_DT" AS TIMESTAMP) >= {ts '2018-06-20 00:00:00'})
> AND (CAST("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."ACTION_DT" AS TIMESTAMP) < {ts '2018-07-20 00:00:00'})
> AND ("APP"."NAME" = 'xxx'))
> GROUP BY "APP_DAILY_ACTIVE_USER_PROPERTY_DI"."AV"
> User: ADMIN
> Success: true
> Duration: 0.06
> Project: app
> {noformat}
> However, recently, I upgrade my Kylin Server to 2.3.1 even 2.4.0, then there are many Tableau reports get the same error due to the SQL contain {fn CURRENT_DATE()}

> Besides, I found that the logs(2.3.1&2.4.0) are different from the logs(2.1.0), the logs(2.4.0) are as below
> {noformat}
> Query Id: b160f20c-84e4-4b81-bfe9-54ed22a723d6
> SQL: SELECT "APP_DAILY_ACTIVE_USER_PROPERTY_DI"."AV" AS "AV",

> FROM "ADL"."APP_DAILY_ACTIVE_USER_PROPERTY_DI" "APP_DAILY_ACTIVE_USER_PROPERTY_DI"
> LEFT JOIN "DIM"."APP" "APP" ON ("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."AC" = "APP"."ID")
> INNER JOIN "DIM"."CALENDAR" "CALENDAR" ON ("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."ACTION_DT" = "CALENDAR"."CAL_DT")
> WHERE ((CAST("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."ACTION_DT" AS TIMESTAMP) >= {fn TIMESTAMPADD(SQL_TSI_DAY,-29,{fn CURRENT_DATE()})})
> AND (CAST("APP_DAILY_ACTIVE_USER_PROPERTY_DI"."ACTION_DT" AS TIMESTAMP) < {fn TIMESTAMPADD(SQL_TSI_DAY,1,{fn CURRENT_DATE()})})
> AND ("APP"."NAME" = 'xxx')
> AND ("APP"."PLATFORM" = 'Android'))
> GROUP BY "APP_DAILY_ACTIVE_USER_PROPERTY_DI"."AV"
> User: ADMIN
> Success: false
> Duration: 0.029
> Project: app
> {noformat}
> The problem that bothers me the most is that why the older version can parse the "fn CURRENT_DATE()" but the newer can't. :( :( :(
