Replace & with & - mysql

Question

When running the following code, I'm encountering an error message saying that the semicolon that I used on this line:
$select_stock->addExpression("REPLACE(b.corporateName, '&', '&')");
for the ampersand is incorrectly placed
InvalidArgumentException: ; is not supported in SQL strings. Use only one statement at a time.
Is there another way to solve this?
public function c_form_db_2($cName) {
$select_stock = $this->connection->select('stock', 'a');
$select_stock->fields('a', ['high', 'low', 'stockname']);
$select_stock->innerJoin('stockdetails', 'b', 'b.high = a.high');
$select_stock->condition('a.isCurrentPrice', 'Yes');
$select_stock->condition('a.isActive', 'Yes');
$select_stock->condition('b.status', 'Closing');
$select_stock->addExpression("REPLACE(b.corporateName, '&', '&')");
$select_stock->escapeLike($cName);
$select_stock->orderBy('a.tickerId', 'DESC');
$select_stock->orderBy('a.volId', 'DESC');
$select_stock_rows = $select_stock->execute()
->fetchAll(\PDO::FETCH_ASSOC);
return $select_stock_rows;
}

I do not know Drupal but I assume REPLACE is the standard MySql function and that Drupal supports all of them. In that case, if by chance you are running MySql 8, then instead of using REPLACE, use REGEXP_REPLACE and match against the regular expression '&amp.' using the wildcard '.' for the ';' character on the assumption that ';' is the only character that will ever be matched by the wildcard.
