Li Xian created CALCITE-3100:
--------------------------------

             Summary: cast(? as DATE) won't work with PreparedStatement
                 Key: CALCITE-3100
                 URL: https://issues.apache.org/jira/browse/CALCITE-3100
             Project: Calcite
          Issue Type: Bug
            Reporter: Li Xian


When I do something like

 
{code:java}
Connection connection =
        DriverManager.getConnection("jdbc:calcite:", info);
PreparedStatement ps = connection.prepareStatement("select * from EMPS where JOINEDAT=cast(? as DATE)");
ps.setString(1, "1996-08-03");
ps.execute();{code}
 

It will produce error like below

 
{code:java}

It looks like that the 'cast' clause doesn't make effect here with the '?' placeholder parameter.

I am able to reproduce this error by adding the below testcase to org.apache.calcite.test.CsvTest and run it
{code:java}
public void testDate() throws Exception {
  Properties info = new Properties();
  info.put("model", jsonPath("model"));
  Connection connection =
          DriverManager.getConnection("jdbc:calcite:", info);
  PreparedStatement ps = connection.prepareStatement("select * from EMPS where JOINEDAT=cast(? as DATE)");
  ps.setString(1, "1996-08-03");
  ps.execute();
}
{code}
