使用jconnect在远程表中插入时出错

Question

当我使用jconnect在远程tabke中执行插入操作时，会出现以下错误：

Unexpected exception : java.sql.SQLException: This transaction has been rolled back, rather than only the current statement.
, sqlstate = ZZZZZjava.sql.SQLException: This transaction has been rolled back, rather than only the current statement.

你知道这可能是什么吗？

下面是我的完整代码：

import java.io.*;
import java.sql.*;

public class connectSybase {

    public static void main(String args[])
    {
        try
        {
            // jconn3 <-- do pessoal do OMS
            //Class.forName("com.sybase.jdbc3.jdbc.SybDriver");

            // jconn4 <-- do servidor de OMS1_PAR_DEV_SQL
            Class.forName("com.sybase.jdbc4.jdbc.SybDriver");

        }
        catch (ClassNotFoundException cnfe)
        {
            System.out.println("BUM!");
        }
        try
        {
            System.out.println("Any of the following may throw an SQLException.");

            System.out.println("Opening a connection.");

            Connection con = java.sql.DriverManager.getConnection
                    ("----------------------------");
            // more code to use connection ...


            System.out.println("Creating a statement object.");

            Statement stmt = con.createStatement();

            System.out.println("Executing the query.");

            ResultSet rs = stmt.executeQuery("Select top 10 * from OMS_DEV..SCRIBE_AR");

            System.out.println("Process the result set.");

            while (rs.next())
            {
                System.out.println("Fetched value " + rs.getString(1));
            }

            System.out.println("Executing the query.");
            int result = stmt.executeUpdate("---------------");


            System.out.println("Process the result set: " + result );

        }

        catch (SQLException sqe)
        {
            sqe.printStackTrace();


            System.out.println("Unexpected exception : " +
                    sqe.toString() + ", sqlstate = " +
                    sqe.getSQLState());
            System.exit(1);
        }
        System.exit(0);
    }
}

我省略了insert和connection，但两者都可以工作，因为我得到了第一次select的结果(只有insert失败)，而且insert也是正确的，因为它使用isql或dbartisan工作。

Sybase错误消息不是特定的，但问题与数据包大小有关。在ASE中是8192，而在IQ中只有2048。

当数据包超过2k时会产生错误。
