Java 代码

        try {

            // 创建存储过程的对象

            CallableStatement c = conn.prepareCall("{call test_in_out_exception(?,?,?)}");



            // 给存储过程的第一个参数设置值

            c.setString(1, "7369");// 7369结果是 800    736900结果是 报错

            c.setInt(2, 24);

            // 注册存储过程的第二个参数

            c.registerOutParameter(3, java.sql.Types.INTEGER);

            // 执行存储过程

            c.execute();

            // 得到存储过程的输出参数值

            System.out.println(c.getInt(3));

        } catch (SQLException e) {

            System.out.println("SQLState : " + e.getSQLState());

            System.out.println("ErrorCode : " + e.getErrorCode());

            System.out.println("Message : " + e.getMessage());

            System.out.println("LocalizedMessage : " + e.getLocalizedMessage());

            //e.printStackTrace();

        } finally {
