Yii2.0中使用Union查询，并使用join，支持分页

$query1 = class1::find()->where($where);
$query2 = class1::find()->alias(‘a’)->join(‘left join’, class2::tablename() . ‘as b’, ‘b.id = a.objid’)->lect(‘a.*’)->where($where2);
$queryall = $query1->union($query2, true);
$qu猕猴桃的功能和作用ery = (new没工作 qu社会热点事件ery())->from([‘c’ => $queryall])->lect(‘c.*,d.type,d.title’)->join(‘left join’, class3::tablename() . ‘as d’, ‘d.id = c.objid’)->distinct(true)->orderby([‘c.time’=>sort_desc]);
$sql = $query-&幻城读后感gt;createcommand()->getrawsql();
$result = $query->offt(($page – 1) * 10)->limit(10)->all();

$totalcount = $query->count();
$pagination = new pagination([‘totalcount如何保护环境’=>$totalcount, ‘pagesize’=>10]);
$result = $query->offt($pagination->offt)->limit($pagination->limit)->all();
