 在SQL SERVER 2000/2005中除了使用DTS进行数据的导入导出,我们也可以使用Transact-SQL语句进行导入导出操作。在Transact-SQL语句中,我们主要使用OpenDataSource函数、OPENROWSET 函数,关于函数的详细说明,请参考SQL联机帮助。 利用下述方法,可以十分容易地实现SQL SERVER、ACCESS、EXCEL数据转换,详细说明如下:

  一、SQL SERVER 和ACCESS的数据导入导出

  常规的数据导入导出:

  使用DTS向导迁移你的Access数据到SQL Server,你可以使用这些步骤:

  1在SQL SERVER企业管理器中的Tools(工具)菜单上,选择Data Transformation

  2Services(数据转换服务),然后选择 czdImport Data(导入数据)。

  3在Choose a Data Source(选择数据源)对话框中选择Microsoft Access as the Source,然后键入你的.mdb数据库(.mdb文件扩展名)的文件名或通过浏览寻找该文件。

  4在Choose a Destination(选择目标)对话框中,选择Microsoft OLE DB Prov ider for SQL Server,选择数据库服务器,然后单击必要的验证方式。

  5在Specify Table Copy(指定表格复制)或Query(查询)对话框中,单击Copy tables(复制表格)。

  6在Select Source Tables(选择源表格)对话框中,单击Select All(全部选定)。下一步,完成。


  Transact-SQL语句进行导入导出:

  1. 在SQL SERVER里查询access数据:

SELECT *

FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',

'Data Source="c:\DB.mdb";User ID=Admin;Password=')...表名


  2. 将access导入SQL server

在SQL SERVER 里运行:

SELECT *

INTO newtable

FROM OPENDATASOURCE ('Microsoft.Jet.OLEDB.4.0',

'Data Source="c:\DB.mdb";User ID=Admin;Password=' )...表名


  3. 将SQL SERVER表里的数据插入到Access表中

  在SQL SERVER 里运行:

insert into OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',

'Data Source=" c:\DB.mdb";User ID=Admin;Password=')...表名

(列名1,列名2)

select 列名1,列名2 from sql表


实例:

insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0',

'C:\db.mdb';'admin';'', Test)

select id,name from Test

 

INSERT INTO OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'c:\trade.mdb'; 'admin'; '', 表名)

SELECT *

FROM sqltablename

    二、 SQL SERVER 和EXCEL的数据导入导出


  1、在SQL SERVER里查询Excel数据:

SELECT *

FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',

'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]


下面是个查询的示例,它通过用于 Jet 的 OLE DB 提供程序查询 Excel 电子表格。

SELECT * 
FROM OpenDataSource ( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\Finance\account.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions


  2、将Excel的数据导入SQL server :

SELECT * into newtable

FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',

'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]


实例:

SELECT * into newtable

FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',

'Data Source="c:\Finance\account.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions


  3、将SQL SERVER中查询到的数据导成一个Excel文件

T-SQL代码:

EXEC master..xp_cmdshell 'bcp 库名.dbo.表名out c:\Temp.xls -c -q -S"servername" -U"sa" -P""'

参数:S 是SQL服务器名;U是用户;P是密码

说明:还可以导出文本文件等多种格式


实例:EXEC master..xp_cmdshell 'bcp saletesttmp.dbo.CusAccount out c:\temp1.xls -c -q -S"pmserver" -U"sa" -P"sa"'


EXEC master..xp_cmdshell 'bcp "SELECT au_fname, au_lname FROM pubs..authors ORDER BY au_lname" queryout C:\ authors.xls -c -Sservername -Usa -Ppassword'


在VB6中应用ADO导出EXCEL文件代码:

Dim cn As New ADODB.Connection

cn.open "Driver={SQL Server};Server=WEBSVR;DataBase=WebMis;UID=sa;WD=123;"

cn.execute "master..xp_cmdshell 'bcp "SELECT col1, col2 FROM 库名.dbo.表名" queryout E:\DT.xls -c -Sservername -Usa -Ppassword'"


  4、在SQL SERVER里往Excel插入数据:

insert into OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',

'Data Source="c:\Temp.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...table1 (A1,A2,A3) values (1,2,3)


T-SQL代码:

INSERT INTO

OPENDATASOURCE('Microsoft.JET.OLEDB.4.0',

'Extended Properties=Excel 8.0;Data source=C:\training\inventur.xls')...[Filiale1$]

(bestand, produkt) VALUES (20, 'Test')


    注:如果你在Sql Server中查询一下Excel文件的时候出现问题:
SELECT *  FROM OPENROWSET( 'MICROSOFT.JET.OLEDB.4.0','Excel 8.0;IMEX=1;HDR=YES;DATABASE=D:\a.xls',[sheet1$])
    结果提示:
    SQL Server 阻止了对组件 'Ad Hoc Distributed Queries' 的 STATEMENT'OpenRowset/OpenDatasource' 的访问,因为此组件已作为此服务器安全配置的一部分而被关闭。系统管理员可以通过使用 sp_configure 启用 'Ad Hoc Distributed Queries'。有关启用 'Ad Hoc Distributed Queries' 的详细信息,请参阅 SQL Server 联机丛书中的 "外围应用配置器"。
    可以采用以下通过启用Ad Hoc Distributed Queries解决:

    启用Ad Hoc Distributed Queries:
exec sp_configure 'show advanced options',1
reconfigure
exec sp_configure 'Ad Hoc Distributed Queries',1
reconfigure
    使用完成后,关闭Ad Hoc Distributed Queries:
exec sp_configure 'Ad Hoc Distributed Queries',0
reconfigure
exec sp_configure 'show advanced options',0
reconfigure

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
