对多行使用SELECT INTO [英] using SELECT INTO with multiple rows

问题描述

这是 我想通过利用SELECT INTO使用查询结果创建一个表. 语法

This is re I want to create a table using the results of a query by utilizing SELECT INTO. The syntax

SELECT *
INTO Persons_Backup
FROM Persons

与我要实现的目标非常接近，不同之处在于我希望FROM将查询用作源.

is very close to what I want to achieve, with the difference being that I want the FROM to use a query as source.

我的情况比这些简单的例子要复杂一些.

My situation is a bit more complicated than these simple examples.

我需要创建一个表并同时插入多行.如果可以(不能)使用以前创建的表，则该语句应如下所示:

I need to create a table and insert multiple rows at the same time. If I could (I can't) use a previously created table the statement would look like this:

INSERT INTO Person_Backup12 (Col1, Col2, Col3)
Select 1, 'a','2001-01-01 12:00'
UNION ALL
Select 83, 'z','2011-09-30 13:27'
UNION ALL
Select 777, 'k','1997-04-25 09:27'

我可以在同时创建表的同时这样做吗?

Can I do that while creating a table at the same time?

推荐答案

您可以将查询放入公共表表达式或派生表中，然后从该表中放入SELECT ... INTO.

You can put your query into a common table expression or derived table then SELECT ... INTO from that.

;WITH cte (Col1, Col2, Col3) AS
(
Select 1, 'a','2001-01-01 12:00'
UNION ALL
Select 83, 'z','2011-09-30 13:27'
UNION ALL
Select 777, 'k','1997-04-25 09:27'
)
SELECT *
INTO NewTable
FROM cte

在这种情况下，您可能需要进行一些显式转换才能获得所需的列数据类型(datetime而不是char等)

In this case you would probably need some explicit casts to get the desired column datatype (datetime rather than char etc.)
