DataBind Wijmo Grid to SQL Analysis Services Data



Provide real-time SQL Analysis Services data to interactive controls.

The Connect Server enables you to use Web services to connect to and query SQL Analysis Services data. This article details how to import an OData feed of SQL Analysis Services data into Wijmo Grid.

Configuring Connect Server

To work with live SQL Analysis Services data in Wijmo Grid, we need to connect to SQL Analysis Services from Connect Server, provide user access to the new virtual database, and create OData endpoints for the SQL Analysis Services data.

Add a Connect Server User

Create a User to connect to SQL Analysis Services from Wijmo Grid through Connect Server.

  1. Click Users -> Add
  2. Configure a User
  3. Click Save Changes and make note of the Authtoken for the new user

Connect to SQL Analysis Services from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Open Connect Server and click Connections
  2. Select "SQL Analysis Services" from Available Data Sources
  3. Enter the necessary authentication properties to connect to SQL Analysis Services.

    To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to SQL Server Analysis Services.

    To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.

    • HTTP Authentication

      Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.

    • Windows (NTLM)

      Set the Windows User and Password and set AuthScheme to "NTLM".

    • Kerberos and Kerberos Delegation

      To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User, Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.

    • SSL/TLS:

      By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

    You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

    See the Getting Started section of the CData documentation, under Retrieving Analysis Services Data, to execute SQL-92 queries to the cubes.

  4. Click Save Changes
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add SQL Analysis Services OData Endpoints in Connect Server

After connecting to SQL Analysis Services, create OData Endpoints for the desired table(s).

  1. Click OData -> Tables -> Add Tables
  2. Select the SQL Analysis Services database
  3. Select the table(s) you wish to work with and click Next
  4. (Optional) Edit the resource to select specific fields and more
  5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

  • Enable cross-origin resource sharing (CORS): ON
  • Allow all domains without '*': ON
  • Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
  • Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Connect to SQL Analysis Services Data using Wijmo Grid

Create a Real-Time Grid

Follow the steps below to consume SQL Analysis Services data from the Wijmo JavaScript controls:

  1. Load the required Wijmo, jQuery, and Knockout libraries:
    			
    			<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
    			<script src="http://code.jquery.com/ui/1.11.0/jquery-ui.min.js"></script>
    
    			<!--Theme-->
    			<link href="http://cdn.wijmo.com/themes/aristo/jquery-wijmo.css" rel="stylesheet" type="text/css">
    
    				<!--Wijmo Widgets CSS-->
    				<link href="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.css" rel="stylesheet" type="text/css">
    
    					<!--Wijmo Widgets JavaScript-->
    					<script src="http://cdn.wijmo.com/jquery.wijmo-open.all.3.20161.90.min.js"></script>
    					<script src="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.js"></script>
    					<script src="http://cdn.wijmo.com/interop/wijmo.data.ajax.3.20161.90.js"></script>
    
    					<!--Knockout JS Library-->
    					<!-- Both of the links below can work -->
    					<script src="http://cdn.wijmo.com/wijmo/external/knockout-2.2.0.js"></script>
    					<!--<script src="http://cdn.wijmo.com/amd-js/3.20161.90/knockout-3.1.0.js"></script>-->
    
    					<!--Wijmo Knockout Integration Library-->
    					<script src="http://cdn.wijmo.com/interop/knockout.wijmo.3.20161.90.js"></script>
    		
  2. Create a ViewModel and connect to it using the ODataView. You will need to replace the placeholder values for the URL of the API Server, an API Server user, and the authtoken for that user.
    			
    			<script id="scriptInit">
    			$.support.cors = true;
    			var viewModel;
    
    			function ViewModel() {
    			var adventure_worksView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/Adventure_Works", {
    			ajax: {
    			dataType: "jsonp",
    			username: "MyUser",
    			password: "MyAuthtoken",
    			data: { "$inlinecount": null }
    			},
    			pageSize: 10
    			});
    			adventure_worksView.refresh();
    			adventure_worksView.nextPage();
    			this.adventure_works = adventure_worksView;
    			this.prevPage = function () {adventure_worksView.prevPage();};
    			this.nextPage = function () {adventure_worksView.nextPage();};
    			}
    
    			$(document).ready(function () {
    			viewModel = new ViewModel();
    			ko.applyBindings(viewModel, $(".container").get(0));
    			});
    			</script>
    		
  3. DataBind: Below is a simple table with some paging buttons, which you can paste into the body section of your markup.
    			
    			<h2>Connect to Live SQL Analysis Services Data in Real Time</h2>
    
    			<h3>Adventure_Works</h3>
    			<div>
    				<button title="previous page" class="pagebuttons" data-bind="click: prevPage, button: {}">
    					<span class="ui-icon ui-icon-seek-prev" />
    				</button>
    				<button title="next page" class="pagebuttons" data-bind="click: nextPage, button: {}">
    					<span class="ui-icon ui-icon-seek-next" />
    				</button>
    			</div>
    			<table id="demo-grid" data-bind="wijgrid: { 
          data: adventure_works, 
          showFilter: true, 
          allowPaging: true,
          pagerSettings: { position: 'none'},
          columnsAutogenerationMode: 'append',
        }" >
    			</table>
    		

At this point, you may be prompted to re-enter the username and authtoken. After doing so, a resulting table or grid should appear, as seen below. You can filter and sort through pages of SQL Analysis Services data.
