![]() ![]() Drop the OrderName column in the Dimensions pane onto the dashboard.The CData driver discovers data types automatically, allowing you to leverage the powerful data processing and visualization features of Tableau. Columns are listed as Dimensions and Measures, depending on the data type. The optimized data processing native to CData ODBC drivers enables unmatched performance in live connectivity. In the Connection menu, select the Live option, so that you skip loading a copy of the data into Tableau and instead work on real-time data. At this point, you can include multiple tables, leveraging the built-in SQL engine to process complex data requests. In the Table box, enter a table name or click New Custom SQL to enter an SQL query.Select the CData Data Source Name (for example: CData OData Source). Click Connect to Data -> More Servers -> Other Databases (ODBC).This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations. When you configure the DSN, you may also want to set the Max Rows connection property. In addition, you will need to specify a URL to a valid OData server organization root or The User and Password properties, under the Authentication section, must be set to valid OData userĬredentials. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs. This is the last step of the driver installation. If you have not already, first specify connection properties in an ODBC DSN (data source name). With built-in dynamic metadata querying, you can visualize and analyze OData services using native Tableau data types. When you issue complex SQL queries from Tableau to OData, the driver pushes supported SQL operations, like filters and aggregations, directly to OData and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. The CData ODBC drivers offer unmatched performance for interacting with live OData services in Tableau due to optimized data processing built into the driver. In this article, you will integrate OData services into a dashboard that reflects changes to OData services in real time. The CData ODBC Driver for OData enables you to access live OData services in business intelligence tools like Tableau. ![]()
