Francis Chuang updated CALCITE-1198:
------------------------------------
Issue Type: Bug (was: Improvement)
> Wrong rep type returned for date, time and timestamps in column metadata
> ------------------------------------------------------------------------
>
> Key: CALCITE-1198
> URL: https://issues.apache.org/jira/browse/CALCITE-1198
> Project: Calcite
> Issue Type: Bug
> Components: avatica
> Affects Versions: avatica-1.7.1
> Environment: Phoenix 4.7.0
> Reporter: Francis Chuang
>
> To reproduce the problem:
> 1. Create a table containing date, time and timestamp columns using
> SquirrelSQL or similiar:
> {code}
> CREATE TABLE test (id INTEGER PRIMARY KEY, tm TIME,dt DATE,tmstmp TIMESTAMP)
> TRANSACTIONAL=false
> {code}
> 2. Use curl to query the phoenix query server/avatica:
> {code}
> curl localhost:8765 -XPOST --data '{"request":
> "openConnection","connectionId": "my-conn"}'
> curl localhost:8765 -XPOST --data '{"request": "prepare","connectionId":
> "my-conn","sql": "SELECT * FROM test","maxRowCount": 1}'
> {code}
> This is the result of the prepare request:
> {code}
> {
> "response": "prepare",

> In the results, {time} and {date} has a rep of {PRIMITIVE_INT} and
> {timestamp} has a rep type of {PRIMITIVE_LONG}. I believe they should have
> rep types of {JAVA_SQL_TIME}, {JAVA_SQL_DATE} and {JAVA_SQL_TIMESTAMP}
> respectively.
> A work around is to use the {name} property which contains the correct JDBC
> name and check to see if it is one of {TIME}, {DATE} or {TIMESTAMP} and
> manually set the correct rep type to decode.
