SELECT INTO使用联合查询

Question

我想在SQL Server中创建一个新表下面的查询。我无法理解，为什么这个查询不起作用。

查询1：工程

SELECT * FROM TABLE1
UNION
SELECT * FROM TABLE2 

QUERY2：不工作。 错误：Msg 170, Level 15, State 1, Line 7 Line 7: Incorrect syntax near ')'.

SELECT * INTO [NEW_TABLE]
FROM
(
SELECT * FROM TABLE1
UNION
SELECT * FROM TABLE2
)

谢谢！

Answer 1

您必须定义一个表别名在SQL Server派生表：

SELECT x.* 
  INTO [NEW_TABLE]
  FROM (SELECT * FROM TABLE1
        UNION
        SELECT * FROM TABLE2) x

“x” 是在该示例表的别名。

INSERT INTO #Temp1
SELECT val1, val2 
FROM TABLE1
 UNION
SELECT val1, val2
FROM TABLE2

Answer 3

您也可以尝试：

create table new_table as
select * from table1
union
select * from table2

Answer 4

select *
into new_table
from table_A
UNION
