Use Servoy Developer to easily connect to Azure Analysis Services data and build web apps with connectivity to live Azure Analysis Services data.
Servoy is a rapid application development and deployment platform. When paired with the CData JDBC Driver for Azure Analysis Services, users can build Azure Analysis Services-connected apps that work with live Azure Analysis Services data. This article describes how to connect to Azure Analysis Services from Servoy and build a simple web app to display and search Azure Analysis Services data.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Azure Analysis Services data. When you issue complex SQL queries to Azure Analysis Services, the driver pushes supported SQL operations, like filters and aggregations, directly to Azure Analysis Services and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying lets you work with Azure Analysis Services data using native data types.
Connect to Azure Analysis Services in Servoy Developer
To build Azure Analysis Services-connected apps, you need to first create a data provider in Servoy Developer using the CData JDBC Driver for Azure Analysis Services.
- Install the JDBC Driver.
- Copy the JDBC Driver JAR file. (cdata.jdbc.aas.jar) to the /application_server/drivers/ directory in the installation directory for Servoy.
- Open Servoy Developer.
- In the Solution Explorer, right-click Database Server (under Resources) and choose "Connect to existing database" -> "empty."
- Name the server.
- Click to show the advanced server settings.
Set the URL, for example: jdbc:aas:URL=asazure://REGION.asazure.windows.net/server;InitiateOAuth=GETANDREFRESH
Built-In Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Azure Analysis Services JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.aas.jar
Fill in the connection properties and copy the connection string to the clipboard.
To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.
Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.
- Select the Driver class you just copied, for example, cdata.jdbc.aas.AASDriver
Build a Azure Analysis Services-Connected Web App
Once you have configured the connection to Azure Analysis Services in the Servoy Developer resources, you are ready to build apps with access to live Azure Analysis Services data.
Create a New Solution
- In the Server Explorer, right-click "All solutions" and select "Create new solution."
- Name the solution.
- Select the checkbox to include the "search" module.
- Click "Finish."
Create a New Form
Right-click "Forms" and select "Create new form."
- Name the form.
- Select a Datasource.
- Set the type (e.g., Simple) and click "Finish."
Add a Data Grid to the Form
- Drag a Data Grid component (from Servoy NG-Grids) onto the form.
Drag a column component onto the Data Grid and set the "dataprovider" property for each column component to a column from the Azure Analysis Services "table" (e.g., Country from the Customer table).
Continue adding columns as desired.
Add Searching to the App
Note that the "svySearch" extension is required to add search functionality (included by default when you create a new solution). If you did not add the extension when you created the solution or you are modifying an existing solution, you can add the search module by right-clicking Modules (in the solution) and selecting "Add Module." Select "svySearch" and click "OK."
- Drag a Text Field component onto the Form.
- Right-click the Form and select "Open in Script Editor."
- Create a new variable (JavaScript) to hold the search value:
var searchText = '';
- Back on the Form, in the Text Field properties:
- Set the "dataprovider" property to the Form variable you just created.
- Double-click to add a method for the onAction event.
- Click to create the method in "Form," name the method (e.g., onEnter), and click "Create private."
- Click "OK & Show."
- Add the following JavaScript to the JavaScript file to use the Servoy framework to implement searching bound data based on the text in the Text Field:
var search = scopes.svySearch.createSimpleSearch(foundset).setSearchText(searchText); search.setSearchAllColumns(); search.loadRecords(foundset);
Save and Launch the App
Save the form and JavaScript file, then click Run -> Launch NGClient to start the web app.
