如果目标表存在，但你不想指定列名:

DECLARE @COLUMN_LIST NVARCHAR(MAX);
DECLARE @SQL_INSERT NVARCHAR(MAX);

SET @COLUMN_LIST = (SELECT DISTINCT
    SUBSTRING(
        (
            SELECT ', table1.' + SYSCOL1.name  AS [text()]
            FROM sys.columns SYSCOL1
            WHERE SYSCOL1.object_id = SYSCOL2.object_id and SYSCOL1.is_identity <> 1
            ORDER BY SYSCOL1.object_id
            FOR XML PATH ('')
        ), 2, 1000)
FROM
    sys.columns SYSCOL2
WHERE
    SYSCOL2.object_id = object_id('dbo.TableOne') )

SET @SQL_INSERT =  'INSERT INTO dbo.TableTwo SELECT ' + @COLUMN_LIST + ' FROM dbo.TableOne table1 WHERE col3 LIKE ' + @search_key
EXEC sp_executesql @SQL_INSERT

有两种不同的方法实现将数据从一个表插入到另一个表。

对于现有表- INSERT INTO SELECT

当先前已经在数据库中创建了表，并且数据将从另一个表插入到这个表中时，使用此方法。如果insert子句和select子句中列出的列相同，则不需要列出它们。出于可读性和可伸缩性的目的，最好总是列出它们。

----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

对于不存在的表- SELECT INTO

如果之前没有创建表，并且需要将一个表中的数据插入到新创建的表中，则使用此方法。使用与所选列相同的数据类型创建新表。

----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

select *
into existing table database..existingtable
from database..othertables....

如果您已经从其他表名中使用了select *到tablename，那么下次要追加时，您可以从其他表名中使用select *到现有表tablename中

如果你想从Table_B插入到Table_A，只有当列不在Table_A时，然后使用以下方法:

BEGIN TRANSACTION

INSERT INTO dbo.Table_A (Column_1)
SELECT DISTINCT Some_Column AS Column_1
FROM dbo.Table_B 
WHERE Some_Column 
    NOT IN (SELECT DISTINCT GroupId 
            FROM dbo.Table_A)

COMMIT

如果你想在新表中创建一个标识列，那么可以如下所示。

SELECT 
 ID = IDENTITY(INT, 1, 1),
        name
INTO    table2
FROM table1    

如果目标表存在，但你不想指定列名:

DECLARE @COLUMN_LIST NVARCHAR(MAX);
DECLARE @SQL_INSERT NVARCHAR(MAX);

SET @COLUMN_LIST = (SELECT DISTINCT
    SUBSTRING(
        (
            SELECT ', table1.' + SYSCOL1.name  AS [text()]
            FROM sys.columns SYSCOL1
            WHERE SYSCOL1.object_id = SYSCOL2.object_id and SYSCOL1.is_identity <> 1
            ORDER BY SYSCOL1.object_id
            FOR XML PATH ('')
        ), 2, 1000)
FROM
    sys.columns SYSCOL2
WHERE
    SYSCOL2.object_id = object_id('dbo.TableOne') )

SET @SQL_INSERT =  'INSERT INTO dbo.TableTwo SELECT ' + @COLUMN_LIST + ' FROM dbo.TableOne table1 WHERE col3 LIKE ' + @search_key
EXEC sp_executesql @SQL_INSERT
