Excel 2007 - Oracle query with parameters

I have a spreadsheet that uses an odbc connection to an oracle database and returns a set of data for a report.  What I would like to do is parameterize the where clause.  I have researched on microsoft's office web site and found a couple of articles that show you how to do it if using an access database but not oracle.  The parameters button is never enabled since my query does not allow you to edit it in design view only sql view.  Is there a way to parameterize an oracle sql statement by storing the values on another sheet?

Would like to have:
1) Setting sheet that contains the release value in the cell(2,1).
2) StatusReport sheet contains the data retrieved from the paramaterize query

WHERE CLAUSE:
r.release = @releaseid

not sure how to reference the parameter

Thanks in advance!

SQL Statement:
SELECT * FROM
(
SELECT c.PROJ_NAME as "Project",
       coalesce(sum(decode(tc.tc_status,'No Run',1,'Failed',1,'Passed',1,'Not Completed',1)),0) as "# of Scenarios",
       coalesce(sum(decode(tc.tc_status,'Failed',1,'Passed',1,'Not Completed',1)),0) as "# Executed",
       coalesce(sum(decode(tc.tc_status,'Passed',1)),0) as "# Pass",
       coalesce(sum(decode(tc.tc_status,'Failed',1)),0) as "# Fail"
FROM
tables
WHERE
r.release = '1.0'
GROUP BY p.PROJ_NAME
)
ORDER BY 1

Did you build the query in code or in the query wizard?

Hi,
Here's how I am making this work in my environment:

1) Under "data" select "from other sources" then "From Microsoft query"
2) Select "new datasource"
3) In "create new datasource" dialog type in new name, select oracle driver and click "connect"
4) Input login details, pick server
5) under "options" pick the default database
6) click OK and return to choose data source dialog
7) click ok - query wizard opens. CANCEL out of it
8) dialog "do you want to continue?" say YES
9) Add tables dialog - add the table you want
10) press "SQL" button in the toolbar
11) Add where clause with "?" as parameter
12) when asked supply a parameter - don't worry this is temporary
13) Choose "return data to Excel ) button on toolbar
14) In import data dialog press "properties"
15) under "definition" tab click "parameters" button
16) I use "getthe value from the following cell" option but you can opt to prompt for a value too

Now every time you refresh the query gets rerun using the parameter supplied, either through a prompt or using a cell in the sheet.

I built the query using toad.  I tried manually adding the tables and kept getting errors with MS Query Wizard when trying to join them.  So, I couldn't get your example to work with multiple joined tabled since my query can't be edited by the Query Wizard.

have you tried rewriting the query in such a way that it might be editable in MS query? You don't need the subquery to get the results you want.

If the query is in VBA code it's easy to add parameters. You just do
query = "SELECT blah FROM table WHERE table.field = " & Range("A1").Value & " AND otherconditions"
I don't know what you meant by toad.

Toad is an oracle query tool.

Yes, I can get it to work using VBA code.  I was trying not to write code.

I could look at rewriting the query.  When I remove the first query select * from...ms query still chokes.

damerval, if you do the parameters in that way how does it affect the query when you view it? Does it show some useful code or does it hard code the values?

To the best of my ability to determine, the parameters are passed using ODBC logic, so the query is not changed, simply run with different parameters. Using the "?" and sequential values seems to be handled automatically.

Since I can't seem to get it to work...I am going to attempt to code the solution for now.
