教义查询 - 忽略空格 [英] Doctrine query - ignoring spaces
问题描述
我正在寻找一种创建无视空格的教义查询的方法。
我尝试替换,但我收到所有的时间
I`m looking for a way to create a doctrine query with ignoring spaces. I try with replace but I receive all the time
预期的已知功能,替换
Expected known function, got 'replace'
我的查询看起来像:
$query = $em->createQueryBuilder();
$query->select('c')
->from('ACME\UserBudnle\Entity\User', 'c')
->where('replace(c.username," ","")'.' LIKE :searchName')
->setParameter('searchName', '%@' . $searchName. '%')
->orderBy('c.username', 'asc');
推荐答案
确定我写了一个替换DQL函数。 >
Ok I write a replace DQL Function.
<?php
namespace Acme\UserBundle\DQL;
use Doctrine\ORM\Query\Lexer;
use Doctrine\ORM\Query\AST\Functions\FunctionNode;
/**
* "REPLACE" "(" StringPrimary "," StringSecondary "," StringThird ")"
*/
class replaceFunction extends FunctionNode{
public $stringFirst;
public $stringSecond;
public $stringThird;
public function getSql(\Doctrine\ORM\Query\SqlWalker $sqlWalker) {
return 'replace('.$this->stringFirst->dispatch($sqlWalker) .','
. $this->stringSecond->dispatch($sqlWalker) . ','
.$this->stringThird->dispatch($sqlWalker) . ')';
}
public function parse(\Doctrine\ORM\Query\Parser $parser) {
$parser->match(Lexer::T_IDENTIFIER);
$parser->match(Lexer::T_OPEN_PARENTHESIS);
$this->stringFirst = $parser->StringPrimary();
$parser->match(Lexer::T_COMMA);
$this->stringSecond = $parser->StringPrimary();
$parser->match(Lexer::T_COMMA);
$this->stringThird = $parser->StringPrimary();
$parser->match(Lexer::T_CLOSE_PARENTHESIS);
}
}
下一个应用/ config.yml我添加:
Next in app/config.yml I add:
doctrine:
orm:
auto_generate_proxy_classes: "%kernel.debug%"
auto_mapping: true
dql:
string_functions:
replace: Acme\UserBundle\DQL\replaceFunction
最后我在我的Controller中创建一个DQL查询:
And finally I create a DQL query in my Controller:
$em = $this->getDoctrine()->getManager();
$query = $em->createQueryBuilder();
$query->select('u')
->from('Acme\UserBundle\Entity\User', 'u')
->where("replace(u.username,' ','') LIKE replace(:username,' ','') ")
->setParameter('username', '%' . $usernameForm . '%')
->orderBy('u.username', 'asc');
$result = $query->getQuery()->getResult();
最有趣的是引号非常重要。这意味着您可以在select,from,setParameter和orderBy中看到,我使用''但是在我使用和space的地方。相反的是没有工作。我不知道为什么
The most funny thing is that "quotes" are very important. It means that you can see that in select, from, setParameter and orderBy I use '' but in where I use "" and space ''. The opposite is not working. I don`t know why.
