Connect to Oracle Service Cloud Data from Blazor Apps

Blazor is a framework for developing modern, client-side web UIs using .NET technology. Instead of coding in JavaScript, developers can use the familiar C# language and .NET libraries to build app UIs.

The CData ADO.NET Provider for Oracle Service Cloud can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Oracle Service Cloud data. Since Blazor supports .NET Core, developers can use CData ADO.NET Providers in Blazor apps. In this article, we will guide you to build a simple Blazor app that talks to Oracle Service Cloud using standard SQL queries.

Install the CData ADO.NET Provider for Oracle Service Cloud

CData ADO.NET Providers allow users to access Oracle Service Cloud just like they would access SQL Server, using simple SQL queries.

Install the Oracle Service Cloud ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "Oracle Service Cloud ADO.NET Data Provider."

Create a Oracle Service Cloud-Connected Blazor App

Start by creating a Blazor project that references the CData ADO.NET Provider for Oracle Service Cloud

1. Create a Blazor project on Visual Studio.
👁 Create a Blazor app project.

2. From the Solution Explorer, right click Dependencies, then click Add Project Reference.
3. In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.OracleServiceCloud.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Oracle Service Cloud\lib etstandard2.0).
👁 Reference ADO.NET for Oracle Service Cloud .dll in the Blazor app.

SELECT Oracle Service Cloud Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a OracleServiceCloudConnection object, set the connection string:

   Using Basic Authentication

   You must set the following to authenticate to Oracle Service Cloud:

   • Url: The Url of the account to connect to.
   • User: The username of the authenticating account.
   • Password: The password of the authenticating account.

   For example: Url=https://abc.rightnowdemo.com;User=user;Password=password;

3. The code below creates a simple Blazor app for displaying Oracle Service Cloud data, using standard SQL to query Oracle Service Cloud just like SQL Server.

    @page "/"
    @using System.Data;
    @using System.Data.CData.OracleServiceCloud;
    
    <h1>Hello, world!</h1>
    
    Welcome to your Data app.
    
    <div class="row">
    <div class="col-12">
    
    @using (OracleServiceCloudConnection connection = new OracleServiceCloudConnection(
    "Url=https://abc.rightnowdemo.com;User=user;Password=password;"))
    {
    var sql = "SELECT Id, LookupName FROM Accounts WHERE DisplayOrder = 12";
    var results = new DataTable();
    
    OracleServiceCloudDataAdapter dataAdapter = new OracleServiceCloudDataAdapter(sql, connection);
    dataAdapter.Fill(results);
    
    <table class="table table-bordered">
    <thead class="thead-light">
    <tr>
    @foreach (DataColumn item in results.Rows[0].Table.Columns)
    {
    <th scope="col">@item.ColumnName</th>
    }
    </tr>
    </thead>
    <tbody>
    @foreach (DataRow row in results.Rows)
    {
    <tr>
    @foreach (var column in row.ItemArray)
    {
    <td>@column.ToString()</td>
    }
    </tr>
    }
    </tbody>
    </table>
    }
    </div>
    </div>
    

4. Rebuild and run the project. The ADO.NET Provider renders Oracle Service Cloud data as an HTML table in the Blazor app. 👁 Query Oracle Service Cloud from Blazor app.
