SQL Server 将一个表中的所有行复制到另一个表中，即重复表

Question

我想保留一张桌子作为历史并用空桌子替换它。我如何通过 Management Studio 执行此操作？

Answer 1

将表复制到要存档的表中：

SELECT * INTO ArchiveTable FROM MyTable

删除表中的所有条目：

DELETE * FROM MyTable

Answer 2

没有 sql server 可供测试，但我认为这只是：

insert into newtable select * from oldtable;

Answer 3

select * into x_history from your_table_here;
truncate table your_table_here;

Answer 4

您可以使用 RAW SQL：

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

或者使用向导：

1. 右键单击数据库 ->任务
   ->导出数据
2. 选择源/目标数据库
3. 选择源/目标表并
   fields
4. 复制数据

然后执行：

TRUNCATE TABLE SOURCE_TABLE

Answer 5

尝试这个单个命令来删除和插入数据：

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

工作示例：

--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

输出：

(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

这将起作用：

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