SQL Server将所有行从一个表复制到另一个表，即重复表

Question

我想保留一个表作为历史记录并将其替换为空白表。我如何通过Management Studio来完成此操作？

Answer 1

复制你的表到一个表归档：

SELECT * INTO ArchiveTable FROM MyTable 

删除表中的所有条目：

DELETE * FROM MyTable 

Answer 2

没有SQL服务器周围进行测试，但我认为这只是：

insert into newtable select * from oldtable; 

Answer 3

要么你可以使用原始SQL：

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

或者使用向导：

1. 右键点击数据库 - >任务 - >导出数据
2. 选择源/目标数据库
3. 选择源/目标表和 领域
4. 将数据复制

然后执行：

TRUNCATE TABLE SOURCE_TABLE 

Answer 4

select * into x_history from your_table_here; 
truncate table your_table_here; 

Answer 5

试试这个一个命令就都删除和插入数据：

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

工作样本：

--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

这将工作：

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