A DESCRIPTION OF THE PROBLEM :
I like to fill a MS Access Database table which contains a Memo field using PreparedStatement and INSERT. It works fine as long as I put a string with length less than 256 charakters into the Memo field. After filling in a string longer than 255 charakters PreparedStatement.setString(null) on the next VARCHAR column throws a SQLException 'Invalid precision value'.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In MS Access create a table which consists of a memo field followed by a simple VARCHAR column (TEXT(50)). Connect the database via ODBC interface and run the code example below.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
[Microsoft][ODBC Microsoft Access Driver]Invalid precision value.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.sql.*;
import java.util.*;

public class PreparedStatementInsert {

private static String driverName = "sun.jdbc.odbc.JdbcOdbcDriver";
private static String databaseName = "jdbc:odbc:PreparedStatementInsert";

private static void insert() {
PreparedStatement statement = null;
Connection connection = null;
try {
Class.forName(driverName);
} catch (ClassNotFoundException e) {
System.out.println(e.getMessage());
}

try {
connection = DriverManager.getConnection(databaseName, null, null);
char[] m500 = new char[500];
Arrays.fill(m500, 'm');
String s500 = new String(m500);
statement = connection.prepareStatement("INSERT INTO INSERT_TABLE VALUES (?, ?)");

// This works
statement.setString(1, "Memo text less than 256 characters");
statement.setString(2, null);
statement.execute();

// This crashes
statement.setString(1, s500);
statement.setString(2, null);
statement.execute();

} catch (SQLException e) {
System.out.println(e.getMessage());
} finally {
try {
statement.close();
connection.close();
} catch (SQLException e1) {
// ignore
}
}
}

public static void main(String[] args) {
insert();
System.out.println("Program finished.");
}
}

CUSTOMER SUBMITTED WORKAROUND :
Do not fill the memo field using PreparedStatement and INSERT. After inserting the whole row I set the memo value by PreparedStatement and UPDATE.
