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();

 

要达到这样子查询：

1、首先引用： use think\db\Where;

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
