ZF2 Doctrine with Symfony < OR null query

Question

如何以与 Doctrine 兼容的方式编写此 "WHERE" 条件？

( ( `translations_es_google`.`translation_date` < `translations_masters`.`translation_date` ) OR ( `translations_es_google`.`translation_date` is null ) )

我尝试过（未成功）的是：

$query1
    ->andWhere('((t.translationDate < m.translationDate) OR (t.translationDate is NULL))');

$query1
    ->andWhere('(t.translationDate < m.translationDate) OR (t.translationDate is NULL)');

Table Doctrine 查询的别名是

t代表tabletranslations_es_google
m代表tabletranslations_masters

当我删除此 "andWhere" 条件时，QueryBuilder 查询的其余部分将按预期执行。

我要执行的查询是

SELECT 
    `translations_masters`.`translation_key` , `translations_masters`.`text_domain` , `translations_masters`.`translation_date` 
FROM 
    `translations_masters` 
LEFT JOIN 
    `translations_es_google` ON ( ( `translations_masters`.`text_domain` = `translations_es_google`.`text_domain` ) AND ( `translations_masters`.`translation_key` =`translations_es_google`.`translation_key` ) ) 
WHERE 
    `translations_masters`.`language_iso` NOT LIKE 'es-Google' AND ( ( `translations_es_google`.`translation_date` < `translations_masters`.`translation_date` ) OR ( `translations_es_google`.`translation_date` is null ) ) 
GROUP BY 
    `translations_masters`.`translation_key` , `translations_masters`.`text_domain` 
ORDER BY 
    `translations_masters`.`translation_date` ASC

根据要求，此查询的 QueryBuilder 版本为：

$query1 = $this->entityManager
    ->createQueryBuilder()
    ->select('m.textDomain , m.translationKey , m.translationDate , m.translationDate AS translationMasterDate , t.translationDate')
    ->from(
        'AMDatabase\Entity\TheVerse\Translations' . $explode1 . $explode2,
        't'
    )
    ->leftJoin(
        'AMDatabase\Entity\TheVerse\TranslationsMasters',
        'm',
        Join::WITH,
        '(m.textDomain = t.textDomain) AND (m.translationKey = t.translationKey)'
    )
    ->groupBy('m.textDomain , m.translationKey')
    ->orderBy(
        'm.translationDate',
        'ASC'
    )
    ->setMaxResults('1');

$query1
    ->andWhere(
        $query1->expr()
               ->notLike(
                   'm.languageIso',
                   ':languageIso'
               )
    )
    ->setParameter(
        'languageIso',
        $value
    );

$query1->andWhere(
    $query1->expr()->orX(
        't.translationDate < m.translationDate',
        't.translationDate IS NULL'
    )
);

$result1 = $query1->getQuery()
                ->getArrayResult();

$query1->getQuery()->getSQL()的输出是

SELECT 
    t0_.text_domain AS text_domain_0, t0_.translation_key AS translation_key_1, t0_.translation_date AS translation_date_2, t0_.translation_date AS translation_date_3, t1_.translation_date AS translation_date_4
FROM 
    thev1010_theverseoftheday.translations_es_google t1_ 
LEFT JOIN 
    thev1010_theverseoftheday.translations_masters t0_ ON ((t0_.text_domain = t1_.text_domain) AND (t0_.translation_key = t1_.translation_key)) 
WHERE 
    t0_.language_iso NOT LIKE ? AND (t1_.translation_date < t0_.translation_date OR t1_.translation_date IS NULL) 
GROUP BY 
    t0_.text_domain, t0_.translation_key 
ORDER BY 
    t0_.translation_date ASC 
LIMIT 1

? 值为 'es-Google'

$query1->getQuery()->getDQL();的输出是

SELECT 
    m.textDomain , m.translationKey , m.translationDate , m.translationDate AS translationMasterDate , t.translationDate 
FROM 
    AMDatabase\Entity\TheVerse\TranslationsEsGoogle t 
LEFT JOIN 
    AMDatabase\Entity\TheVerse\TranslationsMasters m WITH (m.textDomain = t.textDomain) AND (m.translationKey = t.translationKey) 
WHERE 
    m.languageIso NOT LIKE :languageIso AND (t.translationDate < m.translationDate OR t.translationDate IS NULL) 
GROUP BY 
    m.textDomain , m.translationKey 
ORDER BY 
    m.translationDate ASC

? 值为 'es-Google'

Answer 1

orX表达式怎么样？

你可以这样试试：

$query1->andWhere(
    $query1->expr()->orxX(
         't.translationDate < m.translationDate',
         't.translationDate IS NULL'
    )
);

orX 使您能够添加多个条件，以逗号分隔。您还可以将 orX 条件分离到它自己的变量，并将添加到它的所有内容传递给 andWhere 条件。
