Goal: Inserting an excel file to an existing sql server datatable

By google search, there are some code for importing an excel file to a datatable. But it may infer an empty datatable, if I understand it correctly.



So please help me a little bit of C# code.
SQL Server 2008 and C# 4.0/3.5.

Thanks.

--Use a Linked Server
--To simplify queries, you can configure an Excel workbook as a linked server in SQL Server. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
--Q306397 HOWTO: Use Excel with SQL Server Linked Servers and Distributed Queries
--The following code imports the data from the Customers worksheet on the Excel linked server "EXCELLINK" into a new SQL Server table named XLImport1:
SELECT * INTO XLImport1 FROM EXCELLINK...[Customers$]
--You can also execute the query against the source in a passthrough manner by using OPENQUERY as follows:
SELECT * INTO XLImport2 FROM OPENQUERY(EXCELLINK,
    'SELECT * FROM [Customers$]')


--Use Distributed Queries
--If you do not want to configure a persistent connection to the Excel workbook as a linked server, you can import data for a specific purpose by using the OPENDATASOURCE or the OPENROWSET function.
--The following code samples also import the data from the Excel Customers worksheet into new SQL Server tables:
SELECT * INTO XLImport3 FROM OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0',
'Data Source=C:\test\xltest.xls;Extended Properties=Excel 8.0')...[Customers$]

SELECT * INTO XLImport4 FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=C:\test\xltest.xls', [Customers$])

SELECT * INTO XLImport5 FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=C:\test\xltest.xls', 'SELECT * FROM [Customers$]')

The sql table is an existing one. I want to append excel data to the table. If I use import method, I worry that the old table will be overwritten.

Hi,

I would import the new data to a #temp table (either by using "select into" or rather bcp which is faster), then insert the data to the existing table.

Do however consider the amount of data you're inserting. Reason is that "select into" is not logged in the same way as regular "mass-inserts".

Good luck!

:)
