在SQL Server中使用存储过程插入select语句

我试图将一些列从一个表移动到另一个表中，在此过程中，我希望在插入另一个表之前将datetime列转换为Date和time。为此，我使用一个存储过程来应用该条件。但我不能应用这样的条件。下面是我正在使用的表格

dbo.出席人数

Id                                      UserId                                  Status  CheckIn             CheckOut            Date

我应该在哪里将datetime分别转换为考勤表中的date、checkin和checkout列的时间和日期（从用户活动表加上

考勤表的id）？
您可以在您的过程中使用它

INSERT INTO dbo.Attendence(Id,UserId, Date, CheckIn, CheckOut) 
SELECT 
    NEWID() AS Id
    , UserId
    , CAST([DateTime] AS DATE) as dt
    , CAST([DateTime] AS TIME) as chkin
    , CAST([DateTime] AS TIME) as chkout 
FROM dbo.UserActivity UA
WHERE NOT EXISTS
    ( SELECT * FROM dbo.Attendence A 
        WHERE A.UserId = UA.UserId 
            AND A.Date = CAST(UA.[DateTime] AS DATE) 
            AND A.CheckIn = CAST(UA.[DateTime] AS TIME)
            AND A.CheckOut = CAST(UA.[DateTime] AS TIME) )

你可以用这个

SELECT Id=NEWID(),
        UserId,
        SELECT CAST(CONVERT(VARCHAR(10),DateTime,111) AS DATE) AS dt,
        SELECT CONVERT(VARCHAR(12), DateTime, 108) AS chkin,
        SELECT CONVERT(VARCHAR(12), DateTime, 108) AS chkout,
FROM dbo.UserActivity

我应该在哪里将id声明为newId（）？您可以将like
newId（）添加为id
您想对所有行使用相同的id还是对每行使用唯一的id？每行使用唯一的id加上排除已存在的行考勤表中相同用户id和日期时间的记录非常感谢@sarslan:）
SELECT Id=NEWID(),
        UserId,
        SELECT CAST(CONVERT(VARCHAR(10),DateTime,111) AS DATE) AS dt,
        SELECT CONVERT(VARCHAR(12), DateTime, 108) AS chkin,
        SELECT CONVERT(VARCHAR(12), DateTime, 108) AS chkout,
FROM dbo.UserActivity
