先把需求说一下吧。从 MSSQL 中导出一个文章表，需要插入到 PHPCMS 中的内容表 phpcms_content 去，需要做到文章可以发布到不同的栏目中去。也就是说，需要复制一条记录，并修改其 catid，再插入到表尾的位置上。
MySQL 复制一条数据并插入的语句：
1 |
INSERT INTO phpcms_content (SELECT ".$r[$i]['aid']." + 520, ".$r[$i]['cateid'].", news_catid, catid, typeid, areaid, title, style, thumb, keywords, keywords, posids, url, listorder, status, userid, username, inputtime, updatetime, searchid, islink, prefix FROM phpcms_content WHERE contentid = '".$r[$i-1]['aid']."') |
大致为：insert into a SELECT id+1, ...(其它字段) FROM a ;
下面PHP具体程序：
01 |
$query = "SELECT * FROM articleincategory ORDER BY ArticleID "; |
02 |
$result = $connector -> query($query); |
05 |
while($myrow = $connector -> fetch_array($result)) |
07 |
$r[$i]['aid'] = $myrow["ArticleID"]; |
08 |
$r[$i]['cateid'] = $myrow["CategoryID"]; |
12 |
for($i = 0; $i < count($r); $i++) |
16 |
if( $r[$i]['aid'] == $r[$i-1]['aid'] ) |
18 |
echo '第 '. $i. ' 条数据 '. $r[$i]['aid'] .' 与前一条数据 '. $r[$i-1]['aid'] .' 重复'.'<br/>'; |
19 |
$sql = " INSERT INTO phpcms_content (SELECT ".$r[$i]['aid']." + 520, ".$r[$i]['cateid'].", news_catid, catid, typeid, areaid, title, style, thumb, keywords, keywords, posids, url, listorder, status, userid, username, inputtime, updatetime, searchid, islink, prefix FROM phpcms_content WHERE contentid = '".$r[$i-1]['aid']."') "; |
26 |
else if( $r[$i]['aid'] != $r[$i-1]['aid'] ) |
28 |
$sql = " UPDATE phpcms_content SET origin_cateid = '".$r[$i]['cateid']."' WHERE contentid = '".$r[$i]['aid']."' "; |
如果不需要插入，则更简单：insert into mytable (select * from mytable where id=1) ON DUPLICATE KEY UPDATE id=2;
或者： update mytable set id=2 where id=1;
