帝国CMS标签的SQL查询调用,支持调用mysql数据库的所有数据。

本节通过用灵动标签的SQL语句查询来讲解调用方法。

用灵动标签调用外部数据:

例一:调用Discuz的最新贴子

<table width="100%" border="0" cellspacing="1" cellpadding="3"> [e:loop={"select tid,subject,dateline from discuzdb.cdb_threads order by tid desc limit 10",10,24,0}] <tr> <td><a href="/bbs/viewthread.php?tid=<?=$bqr[tid]?>" target="_blank"><?=$bqr[subject]?></a> (<?=date('Y-m-d',$bqr[dateline])?>) </td> </tr> [/e:loop] </table>

discuzdb.cdb_threads为Discuz的贴子表名,其中“discuzdb”为Discuz的数据库名称。

limit 10为显示贴子数量。

如果用伪静态地址可以用:/bbs/thread-<?=$bqr[tid]?>-1-1.html

如果指定单个版块的贴子,SQL用:select tid,subject,dateline from discuzdb.cdb_threads where fid=版块ID order by tid desc limit 10

如果指定多个版块的贴子,SQL用:select tid,subject,dateline from discuzdb.cdb_threads where fid in (1,2,3) order by tid desc limit 10

例二:调用Discuz的最新贴子(含调用论坛版块名)

<table width="100%" border="0" cellspacing="1" cellpadding="3"> [e:loop={"select tid,subject,dateline,fid from discuzdb.cdb_threads order by tid desc limit 10",10,24,0}] <?php $fr=$empire->fetch1("select name from discuzdb.cdb_forums where fid='$bqr[fid]'"); ?>  <tr> <td>[<?=$fr[name]?>] <a href="/bbs/viewthread.php?tid=<?=$bqr[tid]?>" target="_blank"><?=$bqr[subject]?></a> (<?=date('Y-m-d',$bqr[dateline])?>) </td> </tr> [/e:loop] </table>

discuzdb.cdb_forums为Discuz的版块表名,其中“discuzdb”为Discuz的数据库名称。

例三:调用DiscuzX的最新贴子

<table width="100%" border="0" cellspacing="1" cellpadding="3"> [e:loop={"select tid,subject,dateline from discuzdb.pre_forum_thread order by tid desc limit 10",10,24,0}] <tr> <td><a href="/bbs/forum.php?mod=viewthread&tid=<?=$bqr[tid]?>" target="_blank"><?=$bqr[subject]?></a> (<?=date('Y-m-d',$bqr[dateline])?>) </td> </tr> [/e:loop] </table>

discuzdb.pre_forum_thread为DiscuzX的贴子表名,其中“discuzdb”为DiscuzX的数据库名称。

limit 10为显示贴子数量。

如果用伪静态地址可以用:/bbs/thread-<?=$bqr[tid]?>-1-1.html

如果指定单个版块的贴子,SQL用:select tid,subject,dateline from discuzdb.pre_forum_threadwhere fid=版块ID order by tid desc limit 10

如果指定多个版块的贴子,SQL用:select tid,subject,dateline from discuzdb.pre_forum_threadwhere fid in (1,2,3) order by tid desc limit 10

例四:调用DiscuzX的最新贴子(含调用论坛版块名)

<table width="100%" border="0" cellspacing="1" cellpadding="3"> [e:loop={"select tid,subject,dateline,fid from discuzdb.pre_forum_thread order by tid desc limit 10",10,24,0}] <?php $fr=$empire->fetch1("select name from discuzdb.pre_forum_forum where fid='$bqr[fid]'"); ?>  <tr><td> [<?=$fr[name]?>] <a href="/bbs/forum.php?mod=viewthread&tid=<?=$bqr[tid]?>" target="_blank"><?=$bqr[subject]?></a> (<?=date('Y-m-d',$bqr[dateline])?>)  </td></tr> [/e:loop] </table>

discuzdb.pre_forum_forum为DiscuzX的版块表名,其中“discuzdb”为DiscuzX的数据库名称。

例五:调用PHPwind的最新贴子

<table width="100%" border="0" cellspacing="1" cellpadding="3"> [e:loop={"select tid,subject,postdate from phpwinddb.pw_threads order by tid desc limit 10",10,24,0}] <tr><td> <a href="/bbs/read.php?tid=<?=$bqr[tid]?>" target="_blank"><?=$bqr[subject]?></a> (<?=date('Y-m-d',$bqr[postdate])?>)  </td></tr> [/e:loop] </table>

phpwinddb.pw_threads为phpwind的贴子表名,其中“phpwinddb”为phpwind的数据库名称。

limit 10为显示贴子数量。

如果用伪静态地址可以用:/bbs/read-htm-tid-<?=$bqr[tid]?>.html

如果指定单个版块的贴子,SQL用:select tid,subject,postdate from phpwinddb.pw_threadswhere fid=版块ID order by tid desc limit 10

如果指定多个版块的贴子,SQL用:select tid,subject,postdate from phpwinddb.pw_threadswhere fid in (1,2,3) order by tid desc limit 10

例六:调用PHPwind的最新贴子(含调用论坛版块名)

<table width="100%" border="0" cellspacing="1" cellpadding="3"> [e:loop={"select tid,subject,postdate,fid from phpwinddb.pw_threads order by tid desc limit 10",10,24,0}] <?php $fr=$empire->fetch1("select name from phpwinddb.pw_forums where fid='$bqr[fid]'"); ?> <tr> <td>[<?=$fr[name]?>] <a href="/bbs/read.php?tid=<?=$bqr[tid]?>" target="_blank"><?=$bqr[subject]?></a> (<?=date('Y-m-d',$bqr[postdate])?>) </td> </tr> [/e:loop] </table>

phpwinddb.pw_forums为phpwind的版块表名,其中“phpwinddb”为phpwind的数据库名称。
