Use PostgreSQL NOT SIMILAR TO in Symfony Doctrine query builder

Question

I am attempting to use PostgreSQL's NOT SIMILAR TO exclude a blacklist from the results of a query,

When I run the query in my repository method below:

$qb = $this->getEntityManager()->createQueryBuilder('p');

$query = $qb
    ->select('p')
    ->from('CRMPiccoBundle:Person', 'p')
    ->where("lower(p.email) not similar to '(" . implode('|', $blacklist) . ")%'")
    ->getQuery();

return $query->getResult();

I get the following error:

[Doctrine\ORM\Query\QueryException]                                                                                                                
SELECT p FROM CRMPiccoBundle:Person p WHERE lower(p.email) not similar to '(abuse@|admin@|billing@|compliance@|devnull@)%' 

[Doctrine\ORM\Query\QueryException]                                     
[Syntax Error] line 0, col 94: Error: Expected end of string, got 'to'  

However, when I run this query against my local DB with PgAdmin it works.

How can I achieve this with Doctrine using the Symfony Doctrine Query builder (or similar)? I am using PostgreSQL 9.5.5

Answer 1

$qb = $this->getEntityManager()->createQueryBuilder('p');

$select = $qb
    ->select('p')
    ->from('CRMPiccoBundle:Person', 'p')
;

foreach ($blacklist as $key => $item) {
    $select
        ->where('lower(p.email) NOT LIKE :key'.$key)
        ->setParameter('key'.$key, "$item%")
    ;
}

$query = $select->getQuery();

return $query->getResult();
