SQL Server將所有行從一個表複製到另一個表，即重複表

Question

我想保留一個表作爲歷史記錄並將其替換爲空白表。我如何通過Management Studio來完成此操作？

Answer 1

複製你的表到一個表歸檔：

SELECT * INTO ArchiveTable FROM MyTable 

刪除表中的所有條目：

DELETE * FROM MyTable 

Answer 2

沒有SQL服務器周圍進行測試，但我認爲這只是：

insert into newtable select * from oldtable; 

Answer 3

要麼你可以使用原始SQL：

INSERT INTO DEST_TABLE (Field1, Field2) 
SELECT Source_Field1, Source_Field2 
FROM SOURCE_TABLE 

或者使用嚮導：

1. 右鍵點擊數據庫 - >任務 - >導出數據
2. 選擇源/目標數據庫
3. 選擇源/目標表和 領域
4. 將數據複製

然後執行：

TRUNCATE TABLE SOURCE_TABLE 

Answer 4

select * into x_history from your_table_here; 
truncate table your_table_here; 

Answer 5

試試這個一個命令就都刪除和插入數據：

DELETE MyTable 
    OUTPUT DELETED.Col1, DELETED.COl2,... 
     INTO MyBackupTable 

工作樣本：

--set up the tables 
DECLARE @MyTable table (col1 int, col2 varchar(5)) 
DECLARE @MyBackupTable table (col1 int, col2 varchar(5)) 
INSERT INTO @MyTable VALUES (1,'A') 
INSERT INTO @MyTable VALUES (2,'B') 
INSERT INTO @MyTable VALUES (3,'C') 
INSERT INTO @MyTable VALUES (4,'D') 

--single command that does the delete and inserts 
DELETE @MyTable 
    OUTPUT DELETED.Col1, DELETED.COl2 
     INTO @MyBackupTable 

--show both tables final values 
select * from @MyTable 
select * from @MyBackupTable 

OUTPUT：

(1 row(s) affected) 

(1 row(s) affected) 

(1 row(s) affected) 

(1 row(s) affected) 

(4 row(s) affected) 
col1  col2 
----------- ----- 

(0 row(s) affected) 

col1  col2 
----------- ----- 
1   A 
2   B 
3   C 
4   D 

(4 row(s) affected) 

Answer 6

這將工作：

select * into DestinationDatabase.dbo.[TableName1] from (
Select * from sourceDatabase.dbo.[TableName1])Temp
