## Proposed changes
fix[ KYLIN-4382](https://issues.apache.org/jira/browse/KYLIN-4382) Unable to
use DATE type in prepared statements
## Github Branch
As most of the development works are on Kylin 4, we need to switch it as
main branch. Apache Kylin community changes the branch settings on Github since
2021-08-04 :
1. The original branch _kylin-on-parquet-v2_ for **Kylin 4.X** (Parquet
Storage) has been renamed to branch **main**, and configured as the **default**
branch;
2. The original branch _master_ for **Kylin 3.X** (HBase Storage) has been
renamed to branch **kylin3** ;
Please check [Intro to Kylin 4
architecture](https://kylin.apache.org/blog/2021/07/02/Apache-Kylin4-A-new-storage-and-compute-architecture/)
and [INFRA-22166](https://issues.apache.org/jira/browse/INFRA-22166) if you
are interested.

> Key: KYLIN-4382
> URL: https://issues.apache.org/jira/browse/KYLIN-4382
> Project: Kylin
> Issue Type: Bug
> Components: Query Engine
> Reporter: Gabor Arki
> Priority: Major
>
> 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}}
> * Trying to CAST a String to DATE fails with the error described here:
