推荐答案
SELECT A.Id, B1.Priority, B2.Status, A.Name
FROM A
INNER JOIN B as B1 ON B1.Id = A.Priority
INNER JOIN B as B2 ON B2.Id = A.Status;
我应该添加这是Microsoft SQL Server（T-SQL）。它在大多数SQL语言（Oracle，MySql）中可能非常相似，但我不能肯定地说。
为了改善您的问题，请说明数据库类型/ version etc。
I should add this is Microsoft SQL Server (T-SQL). It's probably very similar in most SQL languages (Oracle, MySql) but I can't say for sure.
To improve your question in future, please state the Database type/version etc.
