Data from Excel into SQL
 

Please excuse the cross posting I was not sure which newsgroup would produce
the required advice.

I have a requirement to update a SQL table with data from an Excel
worksheet.

Can anyone suggest the best way to do this....ADO?????

There are numerous variables here. Is this a one-time requirement, or an on-going need? Do you
want to write a program, or just use a utility? If programming, what languages are you open to
using?

ADO is a great way - IMHO. There are many others too. If you fancy
taking the ADO route here's a few useful links:

'Exhaustive list of objects, properties, methos etc.
http://www.devguru.com/Technologies/...cts_index.html

'getting started
http://msdn.microsoft.com/library/de...tml/sqlado.asp

'a good FAQ for commonly experienced problems - beats waiting for
replies on an NG!
http://www.oblique.ch/ms/ADO_Faq.html

And here's some sample code to get you started. Note, there's many ways
to work with ADO and Access - I use RecordSet to retrieve data and
Command to insert or update. Seems to work ok....

This might be a help for getting data to and from Excel and Access: It
includes examples of using variables in SQL queries.
http://www.bygsoftware.com/examples/sql.html

Or you can get there from the "Excel with Access Databases" section on page:
http://www.bygsoftware.com/examples/examples.htm

It demonstrates how to use SQL in Excel's VBA to:

* create a database,
* create a table
* insert records
* select records,
* update records,
* delete records,
* delete a table,
* delete a database.

DAO and ADO files available.

You can also download the demonstration file called "excelsql.zip".

The code is open and commented.

I found the chicken vindaloo recipe particularly useful too - made it,
ate it, loved it. Thanks
