TP5中find_in_set的用法

$id=4;
Db::name('menu')->where('FIND_IN_SET(:id,pid_all)',['id' => $id])->update([$field => $title]);
 
$map[]=['exp','FIND_IN_SET(2,needID)'];
$db->where($map)->select();
 

TP5.1.21   版本之后数组查询支持:

要达到这样子查询:
1、首先引用: use thinkdbWhere;
2、定义数组:$where = new Where;
3、就可以用了:$where['title'] = ['like', "%".$sotitle."%"];
$where['class_id'] = ['in', '$cid_all'];
$where['id'] = ['in', $all_user_id];//或这样子
$where['title'] = ['like', '%php%'];
$where['id'] = ['<>', $id];
$where['id'] = ['notin', $all_user_id];//不等于
//值为数字
$id=419;
$where[] = ['exp',Db::raw("FIND_IN_SET($id,category)")];//category值为数字,例子:419,415,414
//值为字符串
$id值等于dfd 要注意'引号
$where[] = ['exp',Db::raw("FIND_IN_SET('$id',category)")];//category值为数字,例子:'349/417/419','349/413/415','349/413/416
