将新行插入mysql数据库

Question

我能够创建这一行：

20131115      user_jrFeed_item_count,user_jrForum_item_count        {"1":1,"1":2} 

从这个数据库表中：

Chart_date      chart_field                 chart_counts
20131115      user_jrFeed_item_count,      {"1":2}
20131115      user_jrForum_item_count,     {"1":1}

现在，我如何将新行插入现有表并获得以下结果：

 Chart_date     chart_field                                          chart_counts
  20131115      user_jrFeed_item_count ,                              {"1":2}
  20131115      user_jrForum_item_count,                              {"1":1}
  20131115      user_jrFeed_item_count,user_jrForum_item_count,       {"1":1,"1":2} 

Answer 1

你在找这个吗？

INSERT INTO table1(Chart_date, chart_field, chart_counts)
SELECT Chart_date, 
       GROUP_CONCAT(chart_field ) as chart_field, 
       REPLACE(GROUP_CONCAT(chart_counts),'2},{','2,') as chart_counts 
  FROM table1
 GROUP BY Chart_date
