Connect to Oracle Financials Cloud Data from Blazor Apps



Build ASP.NET Core Blazor C# apps that integrate with real-time Oracle Financials Cloud data using standard SQL.

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 Financials Cloud can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live Oracle Financials 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 Financials Cloud using standard SQL queries.

Install the CData ADO.NET Provider for Oracle Financials Cloud

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

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

Create a Oracle Financials Cloud-Connected Blazor App

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

  1. Create a Blazor project on Visual Studio.
  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.OracleERP.dll, typically located at C:\Program Files\CData\CData ADO.NET Provider for Oracle Financials Cloud\lib etstandard2.0).

SELECT Oracle Financials Cloud Data from the Blazor App

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

    Using Basic Authentication

    You must set the following to authenticate to Oracle ERP:

    • Url: The Url of the account to connect to. Typically, the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
    • User: The username of your account.
    • Password: The password of your account.

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

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

          @page "/"
          @using System.Data;
          @using System.Data.CData.OracleERP;
          
          <h1>Hello, world!</h1>
          
          Welcome to your Data app.
          
          <div class="row">
              <div class="col-12">
          
                  @using (OracleERPConnection connection = new OracleERPConnection(
                    "Url=https://abc.oraclecloud.com;User=user;Password=password;"))
                  {
                      var sql = "SELECT InvoiceId, Amount FROM Invoices WHERE Supplier = 'CData Software'";
                      var results = new DataTable();
          
                      OracleERPDataAdapter dataAdapter = new OracleERPDataAdapter(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 Financials Cloud data as an HTML table in the Blazor app.

    At this point, you have a Oracle Financials Cloud-connected Blazor app, capable of working with live Oracle Financials Cloud data just like you would work with a SQL Server instance.
