问题描述
我正在使用symfony2,doctrine 2.3和PostgreSQL 9.我一直在寻找几个小时,看看如何在地球上做一个 ILIKE
选择 QueryBuilder
。 似乎他们只有 LIKE
。在我的情况下,我正在搜索不区分大小写。
如何完成?
// - 这是喜欢;
$ search ='user';
$ query = $ this-> createQueryBuilder('users');
$ query-> where($ query-> expr() - > like('users.username',$ query-> expr() - > literal('%:username%') )) - > setParameter(':username',$ search);
// - 这是我得到的[Syntax Error] line 0,col 86:Error:Expected =,< =,>,> ;> =,!=,获得'ILIKE'
$ search ='user';
$ query = $ this-> createQueryBuilder('users');
$ query- > where('users.username ILIKE:username') - > setParameter(':username',$ search);
我不了解Symphony,但可以替换
a ILIKE b
与
lower(a)LIKE lower(b)
你也可以尝试运算符 ~~ *
,这是 ILIKE
的同义词它具有略低的运算符优先级,所以您可能需要使用连接字符串的括号,您不能使用 ILIKE
a ILIKE b || c
成为
a ~~ *(b || c)
。
我认为这个人有同样的问题,并得到一个答案:
显然,你可以使用SQL供应商特定的功能扩展Symfony2:
我不是ORM和框架的粉丝,只是为了保持便携式(几乎没有工作),捕捉Postgres的丰富功能。
I'm currently using symfony2, doctrine 2.3 and PostgreSQL 9. I've been searching for a couple of hours now to see HOW on earth do I do a ILIKE
select with QueryBuilder
.
It seems they only have LIKE
. In my situation, though, I'm searching case-insensitive.How on earth is it done?
// -- this is the "like";
$search = 'user';
$query = $this->createQueryBuilder('users');
$query->where($query->expr()->like('users.username', $query->expr()->literal('%:username%')))->setParameter(':username', $search);
// -- this is where I get "[Syntax Error] line 0, col 86: Error: Expected =, <, <=, <>, >, >=, !=, got 'ILIKE'
$search = 'user';
$query = $this->createQueryBuilder('users');
$query->where('users.username ILIKE :username')->setParameter(':username', $search);
I don't know about Symphony, but you can substitute
a ILIKE b
with
lower(a) LIKE lower(b)
You could also try the operator ~~*
, which is a synonym for ILIKE
It has slightly lower operator precedence, so you might need parenthesis for concatenated strings where you wouldn't with ILIKE
a ILIKE b || c
becomes
a ~~* (b || c)
The manual about pattern matching, starting with LIKE
/ ILIKE
.
I think this guy had the same problem and got an answer:

Obviously, you can extend Symfony2 with SQL vendor specific functions:
http://docs.doctrine-project.org/projects/doctrine-orm/en/2.1/cookbook/dql-user-defined-functions.html
I am not a fan of ORMs and frameworks butchering the rich functionality of Postgres just to stay "portable" (which hardly ever works).
