query-builder

问题 it's a WHY-question, not How-to one:) I have assigned a Query Bulder to a variable $query: $query = table::where(['id'=>1, 'this_version'=> 1]); $versions['slug1'] = $query->select('tourist_id', 'tourist_version')->get()->toArray(); print_r($versions); outputs array with 2(!) sub-arrays: Array ( [slug1] => Array ( [0] => Array ( [tourist_id] => 1 [tourist_version] => 1 ) [1] => Array ( [tourist_id] => 2 [tourist_version] => 1 ) ) ) But if I add another line using $query between my $query

问题 I need to create a dynamic linq expression for a dynamic search.The basic search is working but it fails to work with collection. I am able to get the book's title and author but fails to get the required page heading. I get the exception in line "left11 = Expression.Property(page1, "Heading");" . I think the expression that i built is unable to recognise the List. How could this be possible? Please see the below code and stacktrace exception. using System; using System.Collections.Generic;

问题 I am trying to add to two different search variations to my project. There is a model "User" and a model "Tag". A User has many Tags. Now I want to be able to search the Users with specific Tags. Either I want to show all Users that has any of the specified tags.

问题 I have a problem with Laravel 4 query builder, i want make a re-usable method public function getData($where=array()) { // $where = array('city' => 'jakarta', 'age' => '25'); return User::where($where)->get(); // this will produce an error, because i think laravel didn't support it } In CodeIgniter it easy to passing array to active record : public function getData($where=array()) { $rs = $this->db->where($where)->from('user')->get(); return $rs->result(); } // it will produce : // SELECT *

问题 Below is my query using Laravel query builder: $begin = new DateTime('2016-07-01'); $end = new DateTime('2016-07-31'); $startDate = $begin->format('Y-m-d 00:00:00'); $endDate = $end->format('Y-m-d 23:59:59'); $deposit = $depositModel->select(DB::raw('user_deposit.user_id as user_id, sum(user_deposit.amount) as total_deposit, null as total_withdraw')) ->whereBetween('date_time', [$startDate, $endDate]) ->where('user_deposit.status', 1) ->groupBy('user_deposit.user_id'); $withdraw =

问题 I'm new with Symfony2 and I built successfully my first join through QueryBuilder and Doctrine 2. Probably this is a stupid question but both on-line and in the Symfony2's methods I was unable to find anything for understanding the difference between the join clauses "WITH" and "ON". For example this is my join code: ->leftJoin('EcommerceProductBundle:ProductData', 'pdata', 'WITH', 'prod.id = IDENTITY(pdata.product)') It works good but if I put ON instead of WITH I get the following error:

问题 I'm using createQueryBuilder to construct queries in Symfony2. But, I don't want to take all columns in this entity. How can I select only the ID and Name? $query = $this->getEntityManager()->createQueryBuilder(); $query ->select('d') ->from('AcmeBundle:Demo', 'd') ->leftjoin('d.otherEntity', 'o'); $query->setMaxResults(10); $results = $query->getQuery()->getResult(); Thank you so much, 回答1: Try following, $fields = array('d.id', 'd.name', 'o.id'); //$fields = 'partial d.{id, name}, partial o

问题 I have no qlue why I can't get the following to work: DB::table('twitter_hashtags')->paginate(5); Every single time I get (the second number tends to differs) Allowed memory size of 134217728 bytes exhausted (tried to allocate 95735352 bytes) I tried using as in (18776710), but that did not make any difference DB::connection()->disableQueryLog(); Removing ->paginate(5) does not make any difference. When I try: DB::select('SELECT * FROM twitter_hashtags'); It works fine, but then I can't use

问题 I want to run a MySQL query like this- SELECT country_ID*2/id*3.159 as my_id FROM `state` WHERE my_id>2; When I run it, I am getting an error like this- 1054 - Unknown column 'my_id' in 'where clause' Is there any alternative solution to search in my new created virtual column my_id ?
