Hi ,

I am new to metamatrix and it would be helpful if anyone give me the sample code for connector to connect to excel or any links to refer for this.

Thanks,

    MetaMatrix has limited abilities to connecto to Excel spreadsheets as sources. Is this the kind of connection you are looking for? If so, I can follow up with more detailed information.

    You can import meatadata from the spreadsheet using the JDBC importer and the jdbd:odbc bridge driver. The correct syntax for the URL is:

    "jdbc:odbc:Driver={MicroSoft Excel Driver(*.xls)};DBQ=<path-to-excel-file>"

    Once you have created the metamodel and the VDB, you can use the Excel connector to bind to the spreadsheet.

    Some important considerations, there a many more minor considerations:
    This is a read only solution, as Update and Delete are not supported.
    The first row in each spreadsheet should contain the column name, not data.
    The fils should not be open in Excel while importing or querying data.

    BTW, what version of MeataMatrix do you have? Since we're not open yet (we're working very hard on it now), you should be able to get assistance from support?

    We already have the the abilty to import metadata from a spreadsheet with existing importers and we have a conector that can query data contained in a spreadsheet. You would only need to write a connector if the existing technology didn't meet your needs.

    If your use case it to expose data contained in a spreadsheet through metamatrix, then you do the following:

    1. Create a new project.
    2. Import the metadata from the spreadsheet to create a new model.
    3. Add the model to a VDB.
    4. Bind the VDB to the spreadsheet with the existing Excel connector.
    5. Query the data.
