如何在SQL Server 2008中使用新名称创建重复的表

Question

如何在SQL Server 2008中创建只有与新名称重复的结构的重复表？

我有45个字段的表,所以我想创建具有相同结构但新名称的新表.

Answer 1

右键单击SQL Management Studio中的表.

选择脚本...创建到...新查询窗口.

这将生成一个脚本,以在新的查询窗口中重新创建表.

将脚本中的表名更改为您希望命名新表的名称.

执行脚本.

Answer 2

SELECT * 
INTO target
FROM  source
WHERE 1 = 2

Answer 3

  SELECT * INTO newtable FROM oldtable where 1=2

Where 1=2 当您需要复制表的完整结构而不复制数据时使用。

 SELECT * INTO newtable FROM oldtable 

要创建包含数据的表，您可以使用此语句。

Answer 4

从现有表创建新表：（将 Old_Table 中的所有行复制到 de New_Table）：

SELECT * INTO New_table FROM  Old_Table

要将数据从一个表复制到另一个表（当您已经创建它们时）：

Insert into Table_Name2 select top 1 * from Table_Name1

请记住删除top 1参数并在需要时应用相关的 where 子句Select

Answer 5

Here, I will show you 2 different implementation:

First:

If you just need to create a duplicate table then just run the command:

SELECT top 0 * INTO [dbo].[DuplicateTable]
FROM [dbo].[MainTable]

Of course, it doesn't work completely. constraints don't get copied, nor do primary keys, or default values. The command only creates a new table with the same column structure and if you want to insert data into the new table.

Second (recommended):

But If you want to duplicate the table with all its constraints & keys follows this below steps:

1. Open the database in SQL Management Studio.
2. Right-click on the table that you want to duplicate.
3. Select Script Table as -> Create to -> New Query Editor Window. This will generate a script to recreate the table in a new query window.
4. Change the table name and relative keys & constraints in the script.
5. Execute the script.
