[英]Is it possible to re-use a Kohana ORM query for the row count?
So I have my query as so...所以我有我的疑问......
$records = ORM::factory('category');
Add a WHERE clause as so...像这样添加一个 WHERE 子句...
$records = $records->where('categoryid', 'LIKE', 'aa');
Grab a count for pagination as so...抓住分页计数,这样......
$count = $records->count_all();
And my where clause gets cleared away as so...我的where子句被清除了......
SELECT `categories`.* FROM `categories` LIMIT 20 OFFSET 0
With this line commented out将此行注释掉
//$count = $records->count_all();
My SQL looks just fine...我的 SQL 看起来还不错……
SELECT `categories`.* FROM `categories` WHERE `categoryid` LIKE 'aa' LIMIT 20 OFFSET 0
Is it possible to use a single query the way I'm trying to or do I have to make two duplicate identical queries?是否可以按照我尝试的方式使用单个查询,或者我是否必须进行两个重复的相同查询? One for the count, and one for the actual results...
一个用于计数,一个用于实际结果...
Thanks!谢谢!
Use special reset(FALSE)
call:使用特殊
reset(FALSE)
调用:
$records = $records->where('categoryid', 'LIKE', 'aa');
$records->reset(FALSE); // !!!!
$count = $records->count_all();
$categories = $records->find_all();
