select *
into tmp
from orders

看起来不错，但只有当tmp不存在时才有效（创建并填充）。（SQL服务器）

要插入现有tmp表：

set identity_insert tmp on

insert tmp 
([OrderID]
      ,[CustomerID]
      ,[EmployeeID]
      ,[OrderDate]
      ,[RequiredDate]
      ,[ShippedDate]
      ,[ShipVia]
      ,[Freight]
      ,[ShipName]
      ,[ShipAddress]
      ,[ShipCity]
      ,[ShipRegion]
      ,[ShipPostalCode]
      ,[ShipCountry] )
      select * from orders

set identity_insert tmp off

Try:

INSERT INTO table1 ( column1 )
SELECT  col1
FROM    table2  

这是标准的ANSI SQL，适用于任何DBMS

它绝对适用于：

神谕MS SQL ServerMySQL数据库Postgres公司SQLite v3Teradata公司分布式数据库Sybase公司Vertica公司hsql数据库氢气AWS红移萨普哈纳谷歌扳手

大多数数据库遵循基本语法，

INSERT INTO TABLE_NAME
SELECT COL1, COL2 ...
FROM TABLE_YOU_NEED_TO_TAKE_FROM
;

我使用的每个数据库都遵循这种语法，即DB2、SQL Server、MY SQL、PostgresQL

从任何其他表插入多条记录的最佳方法。

INSERT  INTO dbo.Users
            ( UserID ,
              Full_Name ,
              Login_Name ,
              Password
            )
            SELECT  UserID ,
                    Full_Name ,
                    Login_Name ,
                    Password
            FROM    Users_Table
            (INNER JOIN / LEFT JOIN ...)
            (WHERE CONDITION...)
            (OTHER CLAUSE)

如果您想在表中插入一些数据而不想写入列名。

INSERT INTO CUSTOMER_INFO
   (SELECT CUSTOMER_NAME,
           MOBILE_NO,
           ADDRESS
      FROM OWNER_INFO cm)

其中表格如下：

            CUSTOMER_INFO               ||            OWNER_INFO
----------------------------------------||-------------------------------------
CUSTOMER_NAME | MOBILE_NO | ADDRESS     || CUSTOMER_NAME | MOBILE_NO | ADDRESS 
--------------|-----------|---------    || --------------|-----------|--------- 
      A       |     +1    |   DC        ||       B       |     +55   |   RR  

结果：

            CUSTOMER_INFO               ||            OWNER_INFO
----------------------------------------||-------------------------------------
CUSTOMER_NAME | MOBILE_NO | ADDRESS     || CUSTOMER_NAME | MOBILE_NO | ADDRESS 
--------------|-----------|---------    || --------------|-----------|--------- 
      A       |     +1    |   DC        ||       B       |     +55   |   RR
      B       |     +55   |   RR        ||

只需在INSERT中使用SELECT子句的括号。例如：

INSERT INTO Table1 (col1, col2, your_desired_value_from_select_clause, col3)
VALUES (
   'col1_value', 
   'col2_value',
   (SELECT col_Table2 FROM Table2 WHERE IdTable2 = 'your_satisfied_value_for_col_Table2_selected'),
   'col3_value'
);
