Use CData Power BI Connectors to visualize SingleStore data in Power BI.
CData Power BI Connectors provide self-service integration with Microsoft Power BI. The CData Power BI Connector for SingleStore links your Power BI reports to real-time SingleStore data. You can monitor SingleStore data through dashboards and ensure that your analysis reflects SingleStore data in real time by scheduling refreshes or refreshing on demand. This article details how to use the Power BI Connector to create real-time visualizations of SingleStore data in Microsoft Power BI Desktop.

Collaborative Query Processing
The CData Power BI Connectors offer unmatched performance for interacting with live SingleStore data in Power BI due to optimized data processing built into the connector. When you issue complex SQL queries from Power BI to SingleStore, the connector pushes supported SQL operations, like filters and aggregations, directly to SingleStore and utilizes the embedded SQL Engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze SingleStore data using native Power BI data types.
Connect to SingleStore as a Power BI Data Source
Installing the Power BI Connector creates a DSN (data source name) called CData Power BI SingleStore. This the name of the DSN that Power BI uses to request a connection to the data source. Configure the DSN by filling in the required connection properties.
You can use the Microsoft ODBC Data Source Administrator to create and configure the DSN: From the Start menu, enter "ODBC Data Sources" and select the CData PowerBI REST DSN. Ensure that you run the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit). You can also use run the ConfigureODBC.exe tool located in the installation folder for the connector.
The following connection properties are required in order to connect to data.
- Server: The host name or IP of the server hosting the SingleStore database.
- Port: The port of the server hosting the SingleStore database.
- Database (Optional): The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.
Connect Using Standard Authentication
To authenticate using standard authentication, set the following:
- User: The user which will be used to authenticate with the SingleStore server.
- Password: The password which will be used to authenticate with the SingleStore server.
Connect Using Integrated Security
As an alternative to providing the standard username and password, you can set IntegratedSecurity to True to authenticate trusted users to the server via Windows Authentication.
Connect Using SSL Authentication
You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:
- SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
- SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
- SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
- SSLClientCertType: The certificate type of the client store.
- SSLServerCert: The certificate to be accepted from the server.
Connect Using SSH Authentication
Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:
- SSHClientCert: Set this to the name of the certificate store for the client certificate.
- SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
- SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
- SSHClientCertType: The certificate type of the client store.
- SSHPassword: The password that you use to authenticate with the SSH server.
- SSHPort: The port used for SSH operations.
- SSHServer: The SSH authentication server you are trying to authenticate against.
- SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
- SSHUser: Set this to the username that you use to authenticate with the SSH server.
How to Query SingleStore Tables
Follow the steps below to build a query to pull SingleStore data into the report:
- Open Power BI Desktop and click Get Data -> Other -> CData SingleStore.
- Select CData PowerBI SingleStore in the Data Source Name menu and select a data connectivity mode:
Select Import if you want to import a copy of the data into your project. You can refresh this data on demand.
Select DirectQuery if you want to work with the remote data. - Select tables in the Navigator dialog.
In the Query Editor, you can customize your dataset by filtering, sorting, and summarizing SingleStore columns. Click Edit to open the query editor. Right-click a row to filter the rows. Right-click a column header to perform actions like the following:
- Change column data types
- Remove a column
- Group by columns
Power BI detects each column's data type from the SingleStore metadata retrieved by the connector.
Power BI records your modifications to the query in the Applied Steps section, adjusting the underlying data retrieval query that is executed to the remote SingleStore data. When you click Close and Apply, Power BI executes the data retrieval query.
Otherwise, click Load to pull the data into Power BI.
How to Create Data Visualizations in Power BI
After pulling the data into Power BI, you can create data visualizations in the Report view by dragging fields from the Fields pane onto the canvas. Follow the steps below to create a pie chart:
- Select the pie chart icon in the Visualizations pane.
- Select a dimension in the Fields pane: for example, ShipName.
- Select a measure in the Fields pane: for example, ShipCity.
You can change sort options by clicking the ellipsis (...) button for the chart. Options to select the sort column and change the sort order are displayed.
You can use both highlighting and filtering to focus on data. Filtering removes unfocused data from visualizations; highlighting dims unfocused data. You can highlight fields by clicking them:
You can apply filters at the page level, at the report level, or to a single visualization by dragging fields onto the Filters pane. To filter on the field's value, select one of the values that are displayed in the Filters pane.
Click Refresh to synchronize your report with any changes to the data.
At this point, you will have a Power BI report built on top of live SingleStore data. Learn more about the CData Power BI Connectors for SingleStore and download a free trial from the CData Power BI Connector for SingleStore page. Let our Support Team know if you have any questions.
