Can't update required field through jdbc


FileMaker Server



Description of the issue

With FMS 11 I can't even prepare a statement that updates a required text field. I have the same problem with the 11.2.70 and 11.3.76 drivers.
It was never a problem with FMS 8.

Steps to reproduce the problem

Create a table "test" with 2 text fields "field1" and "field2". Make "field2" required (not empty).
Then run this program (with the appropriate adjustments for the connection information):

import java.sql.Connection;
import java.sql.SQLException;

import com.filemaker.jdbc3.J3SimpleDataSource;

public class FMTest {
     public static void main(final String... args) throws SQLException {
          final J3SimpleDataSource ds = new J3SimpleDataSource();
          final Connection conn = ds.getConnection();
          conn.prepareStatement("UPDATE test SET field1=?");
          conn.prepareStatement("UPDATE test SET field2=?");

Expected result


Actual result

Configuration information

The server is running on a mac. I don't know what else could be relevant.


Use a real database server, NOT filemaker.
