I've built an excel application that I need to share with many people
within the company, problem is almost none of them have the
non-standard data source defined on their PC, and, seeing as this uses
a service account to access a SQL Server, it would be better that they
not have this data source defined in case they need to access that
server using their own user id... Here is my connection string in VBA:

ActiveSheet.QueryTables.Add(Connection:= _
"ODBC;DSN=aProduction SQLServer -
9;UID=*ServiceAccount*;PWD=*ServiceAccountPasswd*; APP=Microsoft Office
XP;WSID=SYS9962;DATABASE=QDB;Network=DBMSSOCN" _
, Destination:=Range("A1"))

This connection string includes the username and password used for the
connection, it does not include the hostname of the sql server, but
instead, the datasouce name, that is what i'm interested in changing...
Is there any chance I can bypass ODBC when connecting to SQL Server
from excel? or anyway i can, from within VBA, create and drop data
sources on the fly?

Thanks for your time,

-Tim

Tim,
You can use ActiveX Data Objects to connect directly to SQL Server without
an ODBC connection. There are a number of examples and instructions
regarding this subject in the MSDN library
(http://msdn.microsoft.com/library/de...tion1_ado.asp).

The following is a routine I use to extract data from a SQL Server database
and then display the results in Excel. You can modify the routine to prompt
the user to input information to be used in the query and set up the query to
use these variables to make the query more useful.

There are more elegant ways of doing this, but this has worked for me and it
is fairly easy to troubleshoot.

Hope this helps,

Raul

Raul,

Thanks a ton, i hadn't looking into ADO but its a much better way to do
this than through ODBC data sources... I had just spent the last hour
or so trying to build an msi package / installer for the users to run
to create the datasource if it didn't exist on their machine, and those
data sources are stored as hex values in the registry... its VERY
messy... Thanks again...

-Tim

Alternatively, you could create an OLE DB querytable (opposed to ODBC
querytable).
