在 SQL Server 中使用 INNER JOIN 从日期中删除时间戳

Question

我在这里找到了很多东西，但没有任何帮助。我可以删除时间戳，但是当我使用INNER JOIN 时无法删除它。我尝试了很多东西，但它不起作用。

这就是我想要做的：

SELECT 
    CAST(CURRENT_TIMESTAMP as DATE) "END_DATE", LO_ID 
FROM 
    dbo.LO as L 
INNER JOIN 
    dbo.IL as I ON L.LO_ID = I.LO_ID
INNER JOIN 
    dbo.PO as P ON P.LO_ID = I.LO_ID
INNER JOIN 
    dbo.CO as C ON P.CO_ID = C.ID 
WHERE 
    P.LO = 7

我在 LO_ID 处收到错误。使用 INNER JOIN 时如何删除时间戳？

我也尝试过CONVERT 方法而不是CAST。

PS：这是我想要得到的结果：

SELECT * FROM loan.LOANS as L 
INNER JOIN insurance.INSURANCES as I ON L.LOAN_ID = I.LOAN_ID 
INNER JOIN insurance.POLICIES as P ON P.LOAN_ID = I.LOAN_ID 
INNER JOIN insurance.COMPANIES as C ON P.COMPANY_ID = C.ID WHERE P.LOAN_ID = 7

这很好用，这是我所期望的，但总的来说 Date 有一个时间戳，我只想删除那个时间戳

这个查询有什么问题？

SELECT CONVERT(date, [L.END_DATE]) as LOAN_END_DATE, 
       CONVERT(date, [I.END_DATE]) as INSURANCE_END_DATE, 
       L.LOAN_ID 
FROM loan.LOANS as L 
     INNER JOIN insurance.INSURANCES as I ON L.LOAN_ID = I.LOAN_ID 
     INNER JOIN insurance.POLICIES as P ON P.LOAN_ID = I.LOAN_ID 
     INNER JOIN insurance.COMPANIES as C ON P.COMPANY_ID = C.ID WHERE P.LOAN_ID = 7

您应该能够使用 convert 函数删除每个返回字段的时间部分。返回的字段来自主表还是连接表都没有关系。
