I have an Excel Spreadsheet that is populated from a SQL Database. There
are several fields to be updated on a daily basis. I am looking for help
on the code necessary to write the changes back to the SQL database. I
used some ADODB connections strings in other script, but cannot figure out
in Excel VBA.

Thanks
