我有一个SQL Server 2008查询：

select
    account_hcc_id, account_name
from
    [ACCOUNT_HISTORY_FACT]
where
     TOP_ACCOUNT_KEY = (select TOP 1 TOP_ACCOUNT_KEY
                        from ACCOUNT_HISTORY_FACT
                        where account_hcc_id = '3362')
     and ACCOUNT_LEVEL = 1;

我需要将其转换为C＃linq语句。请让我知道我该怎么做。

最佳答案

from ahf in db.ACCOUNT_HISTORY_FACT
where ahf.ACCOUNT_LEVEL == 1 &&
      ahf.TOP_ACCOUNT_KEY == db.ACCOUNT_HISTORY_FACT
                               .Where(x => x.account_hcc_id == "3362")
                               .Select(x => x.TOP_ACCOUNT_KEY)
                               .FirstOrDefault()
select new { ahf.account_hcc_id, ahf.account_name };
