Spider Creates Query With Non-Existent Function

Details

    Description

      First time submitting a bug so please let me know what additional information I should include.

      Query with a GROUP BY on a timestamp datatype executed against a Spider table results in a query that contains a non-existent function on the remote end. Remote tables are partitioned by the SiteID field. SiteID=43 resolves on tr_00043 on the remote server.

      Query errors out with: `SQL Error (1305): FUNCTION trendrecord.add_time does not exist`

      Executed Query on Main: No inclusion of a function called 'add_time' 

      SELECT PointID, DATE_SUB(DATE_FORMAT(TIMESTAMP(datevalue,timevalue), '%Y-%m-%d %H:%i:%s'), INTERVAL IF(MOD(UNIX_TIMESTAMP(timevalue),30)>(30/2),-(30- MOD(UNIX_TIMESTAMP(timevalue),30)), MOD(UNIX_TIMESTAMP(timevalue),30)) SECOND) AS 'ts', ROUND(NumericValue,0) AS 'value'
      		 
      		FROM tr
      		 
      		WHERE SiteID=43 AND PointID IN(88236,88240,490361,88234,88235,88239,490360,88242,1971427,1971428) AND datevalue = '2018-06-04' AND timevalue >= '02:36:08'
      		 
      GROUP BY PointID, UNIX_TIMESTAMP(TIMESTAMP(datevalue,timevalue)) DIV 30

      Resultant Query on Remote Database Table: Function Called 'add_time' appears
