熟悉SQL SERVER 2000的数据库管理员都知道,其DTS可以进行数据的导入导出,其实,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*
FROMOpenDataSource( '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
FROMOPENDATASOURCE ('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:
insertintoOpenDataSource( '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:
insertinto OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'C:\db.mdb';'admin';'', Test)
select id,name from Test
INSERTINTOOPENROWSET('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*
FROMOpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]
下面是个查询的示例,它通过用于 Jet 的 OLE DB 提供程序查询 Excel 电子表格。
SELECT*
FROMOpenDataSource ( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\Finance\account.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions
2、将Excel的数据导入SQL server :
SELECT*into newtable
FROMOpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:\book1.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...[Sheet1$]
实例:
SELECT*into newtable
FROMOpenDataSource( '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:
insertintoOpenDataSource( '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:
INSERTINTO
OPENDATASOURCE('Microsoft.JET.OLEDB.4.0',
'Extended Properties=Excel 8.0;Data source=C:\training\inventur.xls')...[Filiale1$]
(bestand, produkt) VALUES (20, 'Test')
总结:利用以上语句,我们可以方便地将SQL SERVER、ACCESS和EXCEL电子表格软件中的数据进行转换,为我们提供了极大方便!

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
