我在 MySQL 中使用 Doctrine 2(更准确地说是 Doctrine ORM 2.1)并希望找到以数字开头的条目。使用本机 SQL,我会编写如下内容:
SELECT * FROM table WHERE name RLIKE '^[0-9]';
但是,当我尝试使用 DQL 执行此操作时,出现以下错误:
[Syntax Error] line 0, col 71: Error: Expected =, <, <=, <>, >, >=, !=, got 'RLIKE'
#0 .../Doctrine/ORM/Query/Parser.php(396): Doctrine/ORM/Query/QueryException::syntaxError('line 0, col 73:...')

我尝试的是:
$regex = '^[0-9]';
$em
->createQuery('
SELECT t
FROM MyEntity t
WHERE t.visible = true
AND t.name RLIKE ?1
ORDER BY t.name ASC')
->setParameter(1, $regex)
->getResult();
然后:
$regex = '^[0-9]';
$em
->createQueryBuilder()
->select('t')
->from('MyEntity', 't')
->where('t.visible = true')
->andWhere(new Doctrine\ORM\Query\Expr\Comparison('t.name', 'RLIKE', '?1'))
->orderBy('t.name', 'ASC')
->getQuery()
->setParameter(1, $regex)
->getResult();
您知道如何在 DQL 中使用 RLIKE 吗?
此致 ;)
