             Summary: EXTRACT function not working in CSVTest
                 Key: CALCITE-1629
                 URL: https://issues.apache.org/jira/browse/CALCITE-1629
             Project: Calcite
          Issue Type: Bug
            Reporter: hongbin ma
            Assignee: Julian Hyde


According to this doc https://calcite.apache.org/docs/reference.html the 
EXTRACT function should work in Calcite. So I'm trying a query with EXTRACT in 
CSVTest:

@Test public void testSelectx() throws SQLException {
  checkSql("model", "select extract(year from JOINEDAT) from EMPS ");
}
the query failed due to:

java.lang.ClassCastException: java.sql.Date cannot be cast to java.lang.Integer

I also tried to change column JOINDAT's type to timestamp and datetime, but end 
up with similar exceptions.
