Question

我正在使用Doctrine 2（Doctrine ORM 2.1，更准确地说）与MySQL，并希望从数字开始查找条目。使用本机SQL，我会写一些类似的东西：

SELECT * FROM table WHERE name RLIKE '^[0-9]';

但是当我尝试使用DQL时，我收到以下错误：

[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:...')
#1 .../Doctrine/ORM/Query/Parser.php(2746): Doctrine/ORM/Query/Parser->syntaxError('=, <, <=, <>, >...')

#8 .../Doctrine/ORM/Query/Parser.php(1218): Doctrine/ORM/Query/Parser->ConditionalExpression()
#9 .../Doctrine/ORM/Query/Parser.php(769): Doctrine/ORM/Query/Parser->WhereClause()
#10 .../Doctrine/ORM/Query/Parser.php(738): Doctrine/ORM/Query/Parser->SelectStatement()

#15 .../Doctrine/ORM/AbstractQuery.php(586): Doctrine/ORM/Query->_doExecute()
#16 .../Doctrine/ORM/AbstractQuery.php(392): Doctrine/ORM/AbstractQuery->execute(Array, 1)

我试过的是：

$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();

那：

$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();

你有什么想法，我如何在DQL中使用RLIKE？

最好的问候;）

好问题，遗憾的是我没有一个好的答案。

唯一想到的是创建自己的DQL函数，如documentation中所述。祝你好运;）

另请查看this question，也许会有所帮助。

如果你解决了这个问题，请发一个答案。
