SQL Server将所有行从一个表复制到另一个表，即复制表

Question

我想将一张表作为历史记录，并将其替换为空表。如何通过Management Studio完成此操作？

Answer 1

将您的表复制到要存档的表中：

SELECT * INTO ArchiveTable FROM MyTable

删除表格中的所有条目：

DELETE * FROM MyTable

Answer 2

select * into x_history from your_table_here;
truncate table your_table_here;

Answer 3

没有sql server可以测试，但我认为它只是：

insert into newtable select * from oldtable;

Answer 4

您可以使用RAW SQL：

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

或使用向导：

1. 右键单击数据库 - ＆gt;任务 - ＆GT;导出数据
2. 选择源/目标数据库
3. 选择源/目标表和 字段
4. 复制数据

然后执行：

TRUNCATE TABLE SOURCE_TABLE

Answer 5

尝试使用单个命令来删除和插入数据：

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

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

这将有效：

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