How to Initialize sessions to a Oracle View from Jet Reports MS Excel

Posted on 2011-03-09

Hello Experts!!!

We have a customer trying to access our Oracle based applications using a Reports Engine so called Jet Reports. The data is then exported to MS Excel and treated there.

We have succesfully connected all application but we face an issue when accesing views.

To access data in views in our application usually we need to "LOGIN" using some simple SQL script.

Within the tools we normally use (Sql Developer, Toad, Oracle Reports Writer) basically the script can be louched and then you can create reports with no issues.

Our client is not seeing a way to sent this sql script from within Jet Reports or from Excel so he can´t access data in the views.

Is there any way to do this in Jet Reports or perhaps has to be done from Excel?

I'm afraid I don't know what is meant by 'Jet Reports'.  I presume it means that your customer means to use the Microsoft Jet OLEDB provider, and therefore probably intends on querying the database using ADO in excel VBA.

Rather than using the Jet provider he should be using a different one.  This will affect the connection string, but likely he won't need to change his SQL or the other ADO code.  See here for a list of providers for Oracle, and connection strings for each: http://www.connectionstrings.com/oracle

I think that your client should know what to do with it.

Best of luck! :)

I forgot to mention, notice how the username and password (optional) is passed via the connection string.  This serves as the 'LOGIN'.

Hello Jon,

Jet Reports is a reporting tool: http://www.jetreports.com/

They connect to different databases and pull data to create reports in Excel.

I hope that clarifies better.

Thank You

Sounds like I was going in the right direction.  Download the installation guide for Jet Reports and see page 16.
On the Connection tab, you can specify where your data is located and how to connect to it.  The fields displayed on this tab depend upon the OLE DB Provider selected.  For example, if you select the OLE DB Provider for Oracle, the Connection tab displays fields for the server name and login.  If you select the OLE DB Provider for SQL Server, then the server name, type of authentication, and database must be furnished.
Here's the guide

Hello Jon,

But I dont see where in that TAB I can enter some Pl/SQL.

We are connected to the DB succesfully but the problem is that we need to also initialize session to the actual application.

What do you think?

Thanks in advance

I'm out of my depth here because I don't know Jet Reports.  I had a bit of a browse on the web and I see that there are two different types of licenses.  One is viewer another is designer.  Designers appear to be given a control called 'Design'.  I wonder if one sets up the query in there.  I couldn't find any references for setting up queries with SQL.  I did however read that reports can be linked to stored procedures but I couldn't find examples how.

Sorry I can't be more helpful.
