MySQL多表之间字段的匹配实现代码

$sql=$empire->query("select table.title,lianxi,table.dizhi,table.id from table,table1 where table1.sid like concat( '%|',table.id,'|%') and table1.id=".$navinfor[id]."");
while($r=$empire->fetch($sql))
{
$title=$r['title'];
$lianxi=$r['lianxi'];
$dizhi=$r['dizhi'];
}

select info.id, info.name from tag,info where info.name like ‘%'+tag.name+'%'

select info.id, info.name from tag,info where info.name like concat( '%',tag.name, '%')
