Provide real-time Snowflake data to interactive controls.
The Connect Server enables you to use Web services to connect to and query Snowflake data. This article details how to import an OData feed of Snowflake data into Wijmo Grid.
About Snowflake Data Integration
CData simplifies access and integration of live Snowflake data. Our customers leverage CData connectivity to:
- Reads and write Snowflake data quickly and efficiently.
- Dynamically obtain metadata for the specified Warehouse, Database, and Schema.
- Authenticate in a variety of ways, including OAuth, OKTA, Azure AD, Azure Managed Service Identity, PingFederate, private key, and more.
Many CData users use CData solutions to access Snowflake from their preferred tools and applications, and replicate data from their disparate systems into Snowflake for comprehensive warehousing and analytics.
For more information on integrating Snowflake with CData solutions, refer to our blog: https://www.cdata.com/blog/snowflake-integrations.
Getting Started
Configuring Connect Server
To work with live Snowflake data in Wijmo Grid, we need to connect to Snowflake from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Snowflake data.
Add a Connect Server User
Create a User to connect to Snowflake from Wijmo Grid through Connect Server.
- Click Users -> Add
-
Configure a User
-
Click Save Changes and make note of the Authtoken for the new user
Connect to Snowflake from Connect Server
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
-
Open Connect Server and click Connections
- Select "Snowflake" from Available Data Sources
-
Enter the necessary authentication properties to connect to Snowflake.
To connect to Snowflake:
- Set User and Password to your Snowflake credentials and set the AuthScheme property to PASSWORD or OKTA.
- Set URL to the URL of the Snowflake instance (i.e.: https://myaccount.snowflakecomputing.com).
- Set Warehouse to the Snowflake warehouse.
- (Optional) Set Account to your Snowflake account if your URL does not conform to the format above.
- (Optional) Set Database and Schema to restrict the tables and views exposed.
See the Getting Started guide in the CData driver documentation for more information.
- Click Save Changes
- 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 Snowflake OData Endpoints in Connect Server
After connecting to Snowflake, create OData Endpoints for the desired table(s).
- Click OData -> Tables -> Add Tables
- Select the Snowflake database
-
Select the table(s) you wish to work with and click Next
- (Optional) Edit the resource to select specific fields and more
- 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 Snowflake Data using Wijmo Grid
Create a Real-Time Grid
Follow the steps below to consume Snowflake data from the Wijmo JavaScript controls:
-
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>
-
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"> $.support.cors = true; var viewModel; function ViewModel() { var productsView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/Products", { ajax: { dataType: "jsonp", username: "MyUser", password: "MyAuthtoken", data: { "$inlinecount": null } }, pageSize: 10 }); productsView.refresh(); productsView.nextPage(); this.products = productsView; this.prevPage = function () {productsView.prevPage();}; this.nextPage = function () {productsView.nextPage();}; } $(document).ready(function () { viewModel = new ViewModel(); ko.applyBindings(viewModel, $(".container").get(0)); }); </script>
-
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 Snowflake Data in Real Time</h2> <h3>Products</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: products, 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 Snowflake data.
