Julian Hyde commented on CALCITE-3338:
--------------------------------------
xzh, Do you have a PR for this? Can you please update the subject/description
of the JIRA case. I would like to know what problem you are fixing. (And what
to put in the release notes.)

> Key: CALCITE-3338
> URL: https://issues.apache.org/jira/browse/CALCITE-3338
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.20.0
> Environment: apache calcite 1.20
> java version "1.8.0_191"
> Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
> Linux 4.15.0-60-generic #67-Ubuntu
> Reporter: Jacob Roldan
> Priority: Major
> Labels: pull-request-available, test
> Time Spent: 3h 50m
> Remaining Estimate: 0h

> I did a test similar to
> org.apache.calcite.jdbc.CalciteRemoteDriverTest#testInsertBatch but in this
> case using preparedStatement instead of statement:
> {code:java}
> @Test public void testInsertBatchWithPreparedStatement() throws Exception {
> final Connection connection = DriverManager.getConnection(
> "jdbc:avatica:remote:factory="
> + LocalServiceModifiableFactory.class.getName());
> assertThat(connection.getMetaData().supportsBatchUpdates(), is(true));
> assertThat(connection.isClosed(), is(false));
> PreparedStatement pst = connection.prepareStatement("insert into
> \"foo\".\"bar\" values (?,?,?,?,?)");
> pst.setInt(1,1);
> pst.setInt(2,1);
> pst.setString(3,"second");
> pst.setInt(4,1);
> pst.setInt(5,1);
> pst.addBatch();
> pst.addBatch();
> int[] updateCounts = pst.executeBatch();
> assertThat(updateCounts.length, is(2));
> assertThat(updateCounts[0], is(1));
> assertThat(updateCounts[1], is(1));
> ResultSet resultSet = pst.getResultSet();
> assertThat(resultSet, nullValue());
> // Now empty batch
> pst.clearBatch();
> updateCounts = pst.executeBatch();
> assertThat(updateCounts.length, is(0));
> resultSet = pst.getResultSet();
> assertThat(resultSet, nullValue());
> connection.close();
> }
> {code}
> And I got weird exceptions:
