SQL Server SELECT到现有表

我试图从一个表中选择一些字段，并将它们插入到存储过程中的一个现有表中。以下是我正在尝试的:

SELECT col1, col2
INTO dbo.TableTwo 
FROM dbo.TableOne 
WHERE col3 LIKE @search_key

我认为选择…成……是用于临时表的，这就是为什么我得到一个dbo错误。表2已经存在。

如何从dbo中插入多行。table1变成dbo。table2 ?

当前回答

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

它的工作原理如下:

insert into Gengl_Del Select Tdate,DocNo,Book,GlCode,OpGlcode,Amt,Narration 
from Gengl where BOOK='" & lblBook.Caption & "' AND DocNO=" & txtVno.Text & ""

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

选择……成……只有当INTO子句中指定的表不存在时才有效-否则，你必须使用:

INSERT INTO dbo.TABLETWO
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

假设dbo中只有两列。TABLETWO -你需要指定列，否则:

INSERT INTO dbo.TABLETWO
  (col1, col2)
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

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
