             Summary: Unable to use DATE type in prepared statements
                 Key: KYLIN-4382
                 URL: https://issues.apache.org/jira/browse/KYLIN-4382
             Project: Kylin
          Issue Type: Bug
          Components: Query Engine
            Reporter: Gabor Arki


h4. Environment
 * Kylin JDBC driver: 3.0.0
 * Kylin server: 3.0.0

h4. Reproduction steps
 * Use a cube with a DATE column (like the derived day_start)
 * Create a prepared statement and try to filter with this column in a where clause
 * Pass the values as java.sql.Date type

h4. Expected result
 * The proper response is provided for the query with the values for the specified date(s)

h4. Actual result
 * No data is returned
 * 
StreamStorageQuery's _Skip cube segment_ log message is containing the filter with an epoch day value, for example: {{}}{{DAY_START GTE [18231]}}
 * Executing the same query from the web UI you get the expected response. Now the same log message is containing the filter in epoch millis format, for example: {{DAY_START IN [1580774400000, 1580860800000]}}

 * Passing the value as String instead of java.sql.Date fails on server-side with: {{exception while executing query: java.lang.String cannot be cast to java.lang.Integer}}
 * Passing the value as java.sql.Timestamp or java.util.Date fails on server-side with: {{exception while executing query: java.lang.Long cannot be cast to java.lang.Integer}}
