将 SQL 查询转换为 TypeORM

我正在尝试将此查询转换为 TypeORM。这是原始查询：

SELECT s.status, COUNT(o.order_status) as count
FROM (SELECT 'pending' as status
      UNION
      SELECT 'pendingPayment'
      UNION
      SELECT 'processingPayment'
      UNION
      SELECT 'processing'
      UNION
      SELECT 'shipping') s
LEFT JOIN `order` o ON s.status = o.order_status
GROUP BY s.status

我不确定我做错了什么。谁能帮我？我希望有人能帮助你解决这个问题。
