从现有的表中创build表（结构）
如何创build新的表结构应该与另一个表相同
我试过了
CREATE TABLE dom AS SELECT * FROM dom1 WHERE 1=2 但没有发生工作错误
尝试：
Select * Into <DestinationTableName> From <SourceTableName> Where 1 = 2
请注意，这不会复制索引，键等
如果要复制整个结构，则需要生成表的“创build脚本”。 您可以使用该脚本创build具有相同结构的新表。 如果需要，也可以将数据转储到新表中。
如果您正在使用企业pipe理器，只需右键单击表并select复制以生成创build脚本。
这是我用来克隆表结构（仅列）…
SELECT TOP 0 * INTO NewTable FROM TableStructureIWishToClone
仅复制结构（复制所有列）
Select Top 0 * into NewTable from OldTable
只复制结构（复制一些列）
Select Top 0 Col1,Col2,Col3,Col4,Col5 into NewTable from OldTable
用数据复制结构
Select * into NewTable from OldTable
如果你已经有了一个结构相同的表，而你只是想复制数据，那就用这个
Insert into NewTable Select * from OldTable
它也许也值得一提，你可以做到以下几点：
右键单击要复制的表格>脚本表格>创build到>新build查询编辑器窗口
然后，在刚刚生成的脚本中右键单击表的名称，将名称更改为想要调用的新表的名称，然后单击“ Execute
Create table abc select * from def limit 0;
这将是确定的工作
您可以使用：
CREATE TABLE foo LIKE bar;
文档在这里 。
我不知道你为什么想这样做，但尝试：
SELECT * INTO NewTable FROM OldTable WHERE 1 = 2
它应该工作。
试试这个..下面的一个复制现有表的整个结构而不是数据。
create table AT_QUOTE_CART as select * from QUOTE_CART where 0=1 ;
如果你想复制数据，然后使用下面的一个：
create table AT_QUOTE_CART as select * from QUOTE_CART ;
我使用下面的存储过程来复制表的模式，包括PK，索引，分区状态。 这不是很快，但似乎做的工作。 我欢迎任何想法如何加快：

SELECT * INTO NewTable FROM OldTable WHERE 1 = 2
Copy the table structure:- select * into newtable from oldtable where 1=2; Copy the table structure along with table data:- select * into newtable from oldtable where 1=1;
在这里find我在找什么。 帮助我回想起3-4年前我用过的东西。
我想重复使用相同的语法，以便能够通过表的连接创build数据表。
经过几次尝试就find了下面的查询。
SELECT a.* INTO DetailsArchive FROM (SELECT d.* FROM details AS d INNER JOIN port AS p ON p.importid = d.importid WHERE p.status = 2) AS a;
-
如果你想复制相同的数据库
Select * INTO NewTableName from OldTableName -
如果另一个数据库
Select * INTO NewTableName from DatabaseName.OldTableName
SELECT * INTO newtable from Oldtable
