Sql server 从现有表创建表（结构）,sql-server,Sql Server,如何创建新表，该表的结构应与另一个表相同我试过了 CREATE TABLE dom AS SELECT * FROM dom1 WHERE 1=2 但出现了不工作错误请尝试： Select * Into <DestinationTableName> From <SourceTableName> Where 1 = 2 从1=2处选择*进入请注意，这不会复制索引、键等如果要复制整个结构，则需要生成表的创建脚本。可以使用该脚本创建具有相同结构的新表。如果需要，还可

如何创建新表，该表的结构应与另一个表相同

我试过了

CREATE TABLE dom AS SELECT * FROM dom1 WHERE 1=2

但出现了不工作错误

请尝试：

Select * Into <DestinationTableName> From <SourceTableName> Where 1 = 2

从1=2处选择*进入

请注意，这不会复制索引、键等

如果要复制整个结构，则需要生成表的创建脚本。可以使用该脚本创建具有相同结构的新表。如果需要，还可以将数据转储到新表中

如果您使用的是Enterprise Manager，只需右键单击该表并选择“复制”即可生成一个创建脚本。

我不知道您为什么要这样做，但请尝试：

SELECT * 
INTO NewTable
FROM OldTable
WHERE 1 = 2

SELECT *
INTO NewTable
FROM OldTable
WHERE 1 = 2

应该有用。

在这里找到了我要找的东西。帮助我回忆起3-4年前我用过的东西

我希望重用相同的语法，以便能够使用表的联接产生的数据创建表

经过几次尝试后，提出了以下查询

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;

这是我用来克隆表结构（仅列）的

这将肯定会起作用

可能还值得一提的是，您可以执行以下操作：

右键单击要复制的表将表脚本化为创建到新查询编辑器窗口

然后，其中是您在已生成的脚本中右键单击的表的名称，请将该名称更改为您希望调用的新表的名称，然后单击执行。。下面的示例复制了现有表的整个结构，但不复制数据

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;

create table AT_QUOTE_CART as select * from QUOTE_CART where 0=1 ;

如果要复制数据，请使用以下方法：

create table AT_QUOTE_CART as select * from QUOTE_CART ;

对于MYSQL:

您可以使用：

CREATE TABLE foo LIKE bar;

仅复制结构（复制所有列）

仅复制结构（复制某些列）

用数据复制结构

Select * into NewTable from OldTable

如果您已经有一个具有相同结构的表，并且您只想复制数据，那么使用这个

Insert into NewTable Select * from OldTable

如果要复制相同的数据库

Select * INTO NewTableName from OldTableName

如果另一个数据库

Select * INTO NewTableName from DatabaseName.OldTableName

我使用以下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，但似乎很管用。我欢迎任何加快速度的想法：

如果要创建一个表，该表中只有要从原始表复制的结构，则可以使用以下命令执行此操作

create table <tablename> as select * from <sourcetablename> where 1>2;

创建表格为select*，其中1>2；

在这种错误的情况下，您可以保留记录并复制结构。

我需要从一个数据库复制一个表到另一个数据库。对于任何使用类似Sequel Ace的GUI的用户，您可以右键单击表，然后单击“复制创建表语法”并运行该查询（您可以编辑查询，例如更改表名、删除外键、添加/删除列，如果需要）

Kevin，只需在您的答案中进行一个小的格式更改：-选择*进入其中1=2Qutbuddin，1=2将阻止数据从源表复制到目标表。自己试试：-创建表Table1（Id int，Name varchar（200））插入表1值（1，'A'）插入表1值（2，'B'））--将创建表1中有数据的表2选择*从表1中进入表2，其中1=2--将创建表1中没有数据的表2选择*从表1中进入表2，其中1=2我认为1=2只是一个奇怪的错误参数，以避免复制数据。我想这也会复制数据吗？他只想要结构。@Ashis Gupta-谢谢，我忘记了“where”：）这不会复制约束和键问题被标记为

，该语法对其无效，仅供参考。由于与MySQL的关系，不应算作答案，而不是与sql server的关系仅供参考-这还保留了主键和索引。简单，很好；）我正在搜索MySQL语法感谢请使用代码标记以提高可读性，这对于解释代码更有用。感谢您提供此代码片段，它可能会提供一些即时帮助。通过说明为什么这是一个很好的解决问题的方法，正确地解释它的教育价值，并将使它对未来有类似但不完全相同问题的读者更有用。特别是，在未经培训的人看来，它似乎也会复制

Oldtable

的内容。如何避免这种情况？在MSSQL 2008 R2中为我提供了一个非常好的解决方案，简单而优雅。有没有一种方法可以使这个副本同时包含索引和主键？要使它更快，可能只需将游标声明为

游标本地快进

。就我个人而言，我试图在不使用游标的情况下创建一个类似的脚本，看看它的性能如何。Hi@mendosi我知道它很旧，但我目前正在考虑生成包含所有杂项（约束/索引/分区/触发器等）以及列定义的创建脚本。我想知道您是否成功地用非游标方法重新创建了它。如果是的话，你介意分享一下吗？非常感谢，谢谢我写的脚本复制了一个或多个表，不使用游标。它也太大了，无法发表评论。相反，我将链接到Hans Michiels的脚本：非常有用，有趣的是，where子句总是错误的！完美的感谢您注意，问题标记为

sql server

，这在sql server中不起作用。此解决方案比附加条件“1=2”更清晰，我建议这是现有答案的副本。在提交新答案之前，通读现有答案，并在适当的情况下添加评论/投票。但这与我在此处使用的create命令执行此操作的现有答案不同。如果您查看@AbhiUrs answer（2015年1月2日），您的答案与他们答案的第一部分类似，尽管有一个稍微不同的where子句。第一部分=>
