I have a dataset that queries an Oracle DB. I am getting an error when I try
to set a parameter in the query. Basically I have the following:
WHERE x.system_num = s.system_num
and na.service_id = x.service_id
and na.location_num = sl.location_num
and sd.device_mux_id = dm2.device_mux_id
and (x.auth_date >= @.param_start)
ORDER BY m.mso_name, sl.system_name, system_type, d.device_address
The error I get is the following:
ORA-00936: missing expression
(System.Data.OracleClient)
When I remove the "and (x.auth_date >= @.param_start)" the error goes away.
The missing expression sounds like I have a comma at the end of the SELECT or
FROM line; but when the param line is removed the error goes away. So I
don't think that is it.
Could it be in how the parameter is set up? Just throwing out ideas here.
Thank you for any help offered.

After several HOURS of silly errors someone found the solution to this
problem. I wanted to post it here so that others can gain from my hours of
frustration. I will not say that it will work in ALL cases; but that it
works in mine and it is something for others to try if they are stuck.
Problem, using Reporting Services 2005 and accessing an Oracle database with
parameters.
In Reporting Services queries of a SQL DB, I have seen the @.param_startdate
used in the query and then the parameter is defined in the "Report
Parameters" option on the "Reports" top menu option.
So, for example
Select *
From sometable
Where sometable.datefield >= @.param_startdate
Then you go modify the Report Parameters option for the project.
If you try this with an ORACLE DB you will get several errors (ORA-00936:
missing expression is one of them).
SOLUTION: To solve this for an ORACLE DB, use the following:
SELECT *
FROM sometable
WHERE sometable.datefield = :param_startdate
-----
Now I am sure that this little ( : ) is documented somewhere in a document
out there somewhere. BUT for crying out loud... such a simple solution that
took 6 hours to find.
Please feel my frustration and I hope I prevent this from happening elsewhere.

I have been having the same problem and my queries look up an Oracle DB
also. I ended up getting so frustrated at mine, that our Oracle DB
Administrator told me to use a program called Toad for Oracle. Used that
which the SQL module in that program works very similar as the Microsoft
Query tool (Data, Import External Data,
New Database Query).
Anyway, I looked at the SQL Statement after building the Query (joining
tables, adding fields, adding criteria filters, etc). And I saw the same
Where table.field LIKE :whatever
Well, I tried using that in the Microsoft Query (SQL Statement) and I end up
getting some other error which I can't duplicate right now. I tried it again
and now it just completely bails me out of excel with the ever famous Debug,
Send Error Report, etc.
Anyway, wasn't sure if you ran into anything more you could share that might
help in my situation.
I also posted this issue somewhere else on here explaining more in detail
about how originally I created the query with one line of criteria where 3 of
my criteria having 5 "or" conditions. When I refresh or return data to Excel
it works fine.
Problem starts occurring if I ever have to go back in to the query to edit
and then try and refresh or return the data again. That's where I get the
ORA-00936 Missing expression error message.
I'm so stuck on this and really need to resolve somehow, because the data
that's returned from this query is used for charts, graphs, pivot tables,
that are all part of a giant VBA I wrote to automate dashboards for a bunch
of engineers.
Anwyay, any suggestions you or anyone might have on this would be greatly
appreciated.
