对不起标题,很难获得冠军。但请尝试阅读下面的陈述。
我想合并具有相同名称项但具有不同信息的表中的数据。 表格示例:
form_no | name | status | date_added
1 | keyboard | OK | 19-APR-2013 (today)
2 | keyboard | NG | 18-APR-2013 (yesterday)
现在我想在我的页面中显示它,只有1个信息合并为:
表视图示例:
No | Item Name | Yesterday Status | Today Status
1 | keyboard | NG | OK
就是这样,我想在表视图中显示它只有1个信息合并。它具有相同的名称,但具有基于date_added的不同状态。
<table>
<td>Item Name</td><td>Yesterday Status</td><td>Today Status</td>
</table>
include ("includes/_db_.php");
$today = date("j-F-Y");
$yesterday = date("j-F-Y", time() - 60 * 60 * 24);
$query = "SELECT * from t_production_status";
$result = mysql_query($query);
while ($data = mysql_fetch_array($result))
{
$item_name = $data['name'];
$status = $data['status'];
$date_added = $data['date_added'];
<tr>
<td><?php echo $item_name; ?></td>
<td><?php echo $status; ?></td> <- this what I want show for yesterday status
<td><?php echo $status; ?></td> <- this what I want show for today status
<td><?php echo $date_added; ?></td>
有什么建议吗?
答案 0 :(得分:0)
您是否尝试在状态表上进行自我加入..
SELECT status1, status2 FROM t_production_status status1 JOIN t_production_status status1
WHERE status1.name = status2.name
AND status1.date = (today)
AND status2.data = (yesterday)
(未经过测试,但它应该是这些内容)
