关于OpenDataSource, OpenRowSet

一、SQL Server(这里测试的是sql server2005；以下6条语句实现的功能均是“取AdventureWorks.HumanResources.Employee表的第一条记录”)

<一>、使用OPENROWSET
1. MSDASQL驱动
SELECT TOP 1 *
FROM OPENROWSET('MSDASQL', 'DRIVER={SQL Server};SERVER=192.168.1.100,1433;UID=myid;PWD=mypassword;', 'select * from AdventureWorks.HumanResources.Employee')

2. SQLNCLI驱动
SELECT TOP 1 *
FROM OPENROWSET('SQLNCLI', 'SERVER=192.168.1.100,1433;UID=myid;PWD=mypassword;', 'select * from AdventureWorks.HumanResources.Employee')

3. SQLOLEDB驱动
SELECT TOP 1 *
FROM OpenRowSet('SQLOLEDB', '192.168.1.100,1433'; 'myid'; 'mypassword', AdventureWorks.HumanResources.Employee)

<二>、使用OPENDATASOURCE
4. MSDASQL驱动
SELECT TOP 1 *
FROM OPENDATASOURCE('MSDASQL', 'DRIVER={SQL Server};SERVER=192.168.1.100,1433;UID=myid;PWD=mypassword;').AdventureWorks.HumanResources.Employee;

5. SQLOLEDB驱动
SELECT  TOP 1 *
FROM OPENDATASOURCE('SQLNCLI', 'SERVER=192.168.1.100,1433;UID=myid;PWD=mypassword;').AdventureWorks.HumanResources.Employee;

6. SQLOLEDB驱动
SELECT TOP 1 *
FROM OpenDataSource('SQLOLEDB', 'Data Source=192.168.1.100,1433;User ID=myid;Password=mypassword').AdventureWorks.HumanResources.Employee

二、Access
1. OpenRowSet
SELECT *
FROM OpenRowSet('Microsoft.Jet.OLEDB.4.0', 'c:\student.mdb'; 'Admin'; '', Access表名)

2. OpenDataSource
SELECT   *
FROM OpenDataSource('Microsoft.Jet.OLEDB.4.0',  'Data Source=c:\student.mdb;User ID=Admin;Password=;')...[Grades]

3. ODBC;Driver=SQL Server;
INSERT INTO test(id, tmp)
SELECT id, temptext
FROM [ODBC;Driver=SQL Server;SERVER=192.168.1.100,1433;UID=myid;PWD=mypassword;database=dbname].dbo.tablename;

三、Excel
<一>、使用OpenRowSet(注意当HDR，IMEX设置不同时查询结果的差异)
1. HDR=No; IMEX=0;
SELECT *
FROM OpenRowSet('MICROSOFT.JET.OLEDB.4.0', 'Excel 8.0; HDR=No; IMEX=0; DATABASE=c:\test.xls', WorkSheetName$)

2. HDR=No; IMEX=1;
SELECT *
FROM OpenRowSet('MICROSOFT.JET.OLEDB.4.0', 'Excel 8.0; HDR=No; IMEX=1; DATABASE=c:\test.xls', WorkSheetName$)

3. HDR=Yes; IMEX=0;
SELECT *
FROM OpenRowSet('MICROSOFT.JET.OLEDB.4.0', 'Excel 8.0; HDR=Yes; IMEX=0; DATABASE=c:\test.xls', WorkSheetName$)

4. HDR=Yes; IMEX=1;
SELECT *
FROM OpenRowSet('MICROSOFT.JET.OLEDB.4.0', 'Excel 8.0; HDR=Yes; IMEX=1; DATABASE=c:\test.xls', WorkSheetName$)

<二>、使用OpenDataSource
SELECT *
FROM OpenDataSource('MICROSOFT.JET.OLEDB.4.0', 'Excel 8.0; HDR=No; IMEX=1; DATABASE=c:\test.xls')...[WorkSheetName$]
