How Do I Hide an ADO Database Connection String from the Client?

Hello,

I have inherited webmaster duties  and am trying to make a page that allows users to select search criteria from a series of dropdowns on a web page and then click a "submit" button to retrieve a list of matching documents.  The code behind the "submit" button builds a query against our SQL Server database and returns the results in an HTML table.  The "old" page hid the database connection string by putting it in an ASP include file.  Since that code ran on the server, it isn't available to my JavaScript routines.  My company requires that the connect string be hidden.  I'm very limited in the tools I can use to do this job so I don't have the flexibility to just pitch evrything and use the ideal language/database.  In addition, everything is "done" except for hiding the string and the deadline is pretty close so there isn't time for massive re-development.  Most of the solutions I've seen on various web sites are of the "you should have used X" variety and these are not at all helpful.  So, does some JavaScript guru know how to do this?

Thanks!
