修改查詢以使用INSERT INTO

Question

我已經開發了一個非常復雜的查詢，現在很難修改它以使用INSERT INTO語句。

查詢（VS語法）：

           @"SELECT s.TagID, se.SessionID, " +
           " @todaysDate " +
           " AS ScanningTime " +
           " FROM (((Student s " +
           " LEFT JOIN [CourseID-ModuleID] cm ON s.CourseID = cm.CourseID) " +
           " LEFT JOIN [ModuleID-SessionID] ms ON cm.ModuleID = ms.ModuleID) " +
           " LEFT JOIN [Session] se ON ms.SessionID = se.SessionID) " +
           " WHERE s.TagID = @tagNo " +
           " AND se.SessionDate = cast(getdate() as date) " +
           " AND se.SessionTimeStart <= @Plus30Min " +
           " AND se.SessionTimeEnd >= @Plus30Min ";

該查詢運行完美，但是我想將查詢結果放入數據庫中已經存在的空表Attendance中。

Attendance table data types

TagID - int
SessionID - varchar
ScanningTime - datetime.

請注意，“出勤表”的數據類型與其他表的數據類型匹配。

我曾嘗試在SELECT語句之前放置“ INSERT INTO Attendance（s.TagID，se.SessionID，ScanningTime）”，但隨后我的查詢不會產生任何結果。

修改查詢以包含INSERT INTO語句的正確方法是什么？ 謝謝

您所有的答案和建議都非常有幫助。 謝謝！

Answer 1

刪除(s.TagID, se.SessionID, ScanningTime) ，然后在選擇之前添加INSERT INTO Attendance

@"INSERT INTO Attendance
 SELECT s.TagID, se.SessionID, "
 etc...

Answer 2

INSERT INTO table2
(column_name(s))
SELECT column_name(s)
FROM table1;

Answer 3

您可以參考以下代碼：

@"INSERT INTO Attendance(
   TagID , 
   SessionID,
   ScanningTime )
SELECT s.TagID, se.SessionID, " +
           " @todaysDate " +
           " AS ScanningTime " +
           " FROM (((Student s " +
           " LEFT JOIN [CourseID-ModuleID] cm ON s.CourseID = cm.CourseID) " +
           " LEFT JOIN [ModuleID-SessionID] ms ON cm.ModuleID = ms.ModuleID) " +
           " LEFT JOIN [Session] se ON ms.SessionID = se.SessionID) " +
           " WHERE s.TagID = @tagNo " +
           " AND se.SessionDate = cast(getdate() as date) " +
           " AND se.SessionTimeStart <= @Plus30Min " +
           " AND se.SessionTimeEnd >= @Plus30Min ";
