DBAL Prepared statement not properly narrowing type? #762
Description
Using DBAL's (4.x) prepare() method does not seem to properly narrow the result type.
#197 shows that the prepare method is properly supported, so I'm not entirely sure why this isn't working
public function temp(): void
{
$sql = <<<SQL
SELECT
product.productId
FROM
product
SQL;
$data = $this->connection->fetchAssociative($sql);
\PHPStan\dumpType($data); // Works fine
$stmt = $this->connection->prepare($sql);
$result = $stmt->executeQuery();
$data = $result->fetchAssociative();
\PHPStan\dumpType($stmt);
\PHPStan\dumpType($result);
\PHPStan\dumpType($data);
