             Summary: when filter is a derived column equals another column query failed
                 Key: KYLIN-5025
                 URL: https://issues.apache.org/jira/browse/KYLIN-5025

          Issue Type: Bug
          Components: Query Engine

Just use the following SQL query to learn_kylin. 
{quote}SELECT
count(*)
FROM KYLIN_SALES as KYLIN_SALES
INNER JOIN KYLIN_CAL_DT as KYLIN_CAL_DT
ON KYLIN_SALES.PART_DT = KYLIN_CAL_DT.CAL_DT
WHERE KYLIN_SALES.PART_DT = KYLIN_CAL_DT.MONTH_BEG_DT
{quote}
that was OK, but if you put the derived column to the left of the filter like the following SQL, query failed.
{quote}SELECT
count(*)
FROM KYLIN_SALES as KYLIN_SALES
INNER JOIN KYLIN_CAL_DT as KYLIN_CAL_DT
ON KYLIN_SALES.PART_DT = KYLIN_CAL_DT.CAL_DT
WHERE  KYLIN_CAL_DT.MONTH_BEG_DT = KYLIN_SALES.PART_DT
{quote}
