Limit function for MySQL, PostgreSQL, SQLite

[reclikp]

Hi, I just wanted to add a limit function that can be useful for nested queries. If we just try to use setMaxResults(1) in a QueryBuilder or LIMIT 1 at the end of a subquery, it will throw errors.

The function is currently available for MySQL, PostgreSQL and SQLite.

Usage of the function:

LIMIT((subquery), limit)

Example:

$subQb = $this->getEntityManager()->createQueryBuilder()
    ->select("category")
    ->from("App\Entity\Category", "category")
    ->orderBy("category.id", "DESC"));
    
$qb = $this->getEntityManager()->createQueryBuilder()
    ->select("expense")
    ->from("App\Entity\Expense", "expense")
    ->andWhere("expense.category = LIMIT((${subQb->getDQL()}), 1)");
