Question

connection = ConnectionUtils.getConnection();
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date now = new Date();
        String dateValue = simpleDateFormat.format(now);
        sql = "insert into news_base(fid,title,date,author) values("+fid+",'"+title+"','"+dateValue+"','Admin')";
        statement = connection.createStatement();
        statement.executeUpdate(sql);

        sql1 = "insert into news_content (cid,fid,content) values("+cid+","+fid+",'"+content+"')";
        statement1 = connection.createStatement();
        statement1.executeUpdate(sql1);

＆＃39; news_base＆＃39;的ID是主键和自动增量。＆＃39; news_base＆＃39;的ID表是针对cid的＆＃39; news_content＆＃39;表

Answer 1

你可以试试这个： -

在statement.executeUpdate(sql);添加此

之后

ResultSet rs = statement.getGeneratedKeys();
if(rs.next())
{
     int your_id = rs.getInt(1);
}

如何获取＆＃39; news_base＆＃39;的ID表？
