Dynamic Parameter Setup to Denodo in Power BI

[Vasanthrk]

Hi Team,

I am creating reusable template in Power BI, I want to setup Dynamic parameter connection for Denodo, I tried multiple ways but not able to setup that, able to set for source file.now using ODBC to connect Denodo from POwer BI. please provide clear steps to setup the Parameters.

Thanks

Hi @Vasanthrk

Connecting Power BI to Denodo with dynamic parameters isn’t straightforward since ODBC doesn’t allow parameterization directly. The trick is to build the connection string yourself in Power Query.

• First, create parameters for ServerName, Port, and DatabaseName in Manage Parameters.

• Then add a blank query and write a custom connection string like:
  "Driver={DenodoODBCDriver};Server=" & ServerName & ";Port=" & Number.ToText(Port) & ";Database=" & DatabaseName & ";UID=your_username;PWD=your_password;"

• Use this string inside Odbc.DataSource() to connect.

• Don’t hardcode credentials store them in the gateway or Windows Credential Manager.

• Finally, save the report as a .pbit template so users can input values (Dev, Test, Prod) when opening.

Hi @Vasanthrk,

Thank you for reaching out to the Microsoft fabric community forum. Also thanks @Akash_Varuna, for his inputs on this thread. I have identified few workarounds that may help resolve the issue.

Based on your description, it appears you are developing a reusable Power BI template that connects to Denodo via ODBC, and you aim to make the connection dynamic by using parameters for the server, database, etc. Although this approach works well for file-based sources, you are encountering difficulties when trying to implement the same technique with Denodo over ODBC.

Note: Power BI does not support directly parameterizing ODBC connection strings through the standard UI in a dynamic way. As a result, you're unable to switch servers or databases dynamically when connecting to Denodo using parameters especially within reusable .pbit templates.

Create Parameters: Go to Home > Manage Parameters > New Parameter, and create: ServerName (e.g., denodo-dev.company.com). Port (e.g., 9999). DatabaseName (e.g., my_db)

Create a Dynamic Connection String: In Power Query Editor, add a Blank Query and paste the following code:

let

    ServerName = ServerNameParameter,

    Port = PortParameter,

    DatabaseName = DatabaseNameParameter,



    ConnectionString =

        "Driver={DenodoODBCDriver};" &

        "Server=" & ServerName & ";" &

        "Port=" & Number.ToText(Port) & ";" &

        "Database=" & DatabaseName & ";" &

        "UID=your_username;" &

        "PWD=your_password;",



    Source = Odbc.DataSource(ConnectionString, [HierarchicalNavigation=true])

in

    Source

Replace your_username and your_password as needed. For production purposes, it is advisable to store credentials securely using Power BI Gateway or Windows Credential Manager instead of embedding them.

Navigate to Your Denodo Tables: After connecting, expand the source to locate your tables. Apply any necessary transformations.

Save as a Template: Go to File > Export > Power BI Template (.pbit). Upon opening, users will be prompted to enter the parameters, such as those for different environments like Dev, Test, or Prod.

Hi @Vasanthrk  After connecting to Denodo via ODBC in Power BI, create a dynamic parameter in Manage Parameters with the required settings. Use the parameter in your query by referencing it in the SQL statement dynamically in Power Query (e.g., SELECT * FROM Table WHERE Column = '" & ParameterName & "').
