An exception occurred while executing a query: SQLSTATE[42883]: Undefined function: 7 ERROR: operator does not exist: json

Question

我正在将 PostgreSQL 与 Symfony 结合使用。

我有一个用户 table 如下：

id | email         | roles
---------------------------------------
1  | abc@gmail.com | ["ROLE_IVM_USER"]

角色列是 JSON 类型，如上所示。

我想使用以下代码获取具有 ROLE_IVM_USER 角色的用户列表：

$queryBuilder
            ->andWhere(sprintf('%s.roles IN (:roles)', $rootAlias))
            ->setParameter('roles', [User::ROLE_IVM_USER]);

导致以下错误：

An exception occurred while executing a query: SQLSTATE[42883]: Undefined function: 7 ERROR: operator does not exist: json = unknown\nLINE 1: ... u0_ WHERE u0_.organization_id =  AND u0_.roles IN () OR...\n ^\nHINT: No operator matches the given name and argument types. You might need to add explicit type casts."

我是 PostgreSQL 的新手，让我知道如何让用户具有 ROLE_IVM_USER

的角色

Answer 1

你可以做 LIKE 而不是 IN :

$queryBuilder
  ->andWhere(sprintf('%s.roles LIKE :roles', $rootAlias))
  ->setParameter('roles', '%' . User::ROLE_IVM_USER . '%');

Answer 2

下面是我如何在不使用任何第三方库的情况下获得预期结果的：

$rsm = $this->createResultSetMappingBuilder('u');

        $rawQuery = sprintf(
            'SELECT %s
                    FROM public.user u
                    WHERE u.roles::jsonb ?? :role',
            $rsm->generateSelectClause()
        );

        $query = $this->getEntityManager()->createNativeQuery($rawQuery, $rsm);
        $query->setParameter('role', $role);
        return $query->getResult();

希望这会对某人有所帮助并节省调查时间
