[英]MySql functions with kohana ORM
I'm bit confuse how to convert my query : 我有点混淆如何转换我的查询:
> SELECT COUNT(`id`) AS `total_logs`, `userlog`.* FROM `user_log` AS
> `userlog` WHERE `user_id` = '31' AND date(`date_created`) =
> '2012-04-30'
to Kohana 3.1 ORM? 到Kohana 3.1 ORM? currently im using :
目前即时使用:
> $isLoged = ORM::factory('Userlog')->select(array('COUNT("id")',
> 'total_logs'))
> ->where('user_id', '=', $user->id)
> ->and_where('Date(date_created)', '=', date('Y-m-d'))
> ->find_all();
unfortunately above one is giving error :( 不幸的是上面一个是错误的:(
Database_Exception [ 1054 ]: Unknown column 'Date(date_created)' in 'where cla....
Database_Exception [1054]:'where cla ...中的未知列'Date(date_created)'
'Date(date_created)'
string will be escaped and treated as a column name, unless you will first pass it to DB::expr()
. 'Date(date_created)'
字符串将被转义并视为列名,除非您首先将其传递给DB::expr()
。 Thus instead of 'Date(date_created)'
try the following: 因此,请尝试以下方法,而不是
'Date(date_created)'
。
DB::expr('Date(date_created)')
See the documentation on DB::expr()
. 请参阅有关
DB::expr()
的文档 。
