Connecting to Relational Database with .NET Core

Requirements

  • Flexmonster Pivot Component version 2.213 or higher
  • Microsoft .NET Core 1.0 and 1.1
  • Driver for the database

Supported databases

  • Oracle Database
  • MySQL
  • Microsoft SQL Server – driver is built-in
  • PostgreSQL
  • Other ADO.NET / ODBC databases

Step 1: Embed the component into your web page

You already have in your HTML page an empty component. If Flexmonster Component is not embedded – return to Quickstart. Your code should look like the following example:

<div id="pivotContainer">The component will appear here</div>
<script src="flexmonster/lib/jquery.min.js"></script>
<script src="flexmonster/flexmonster.js"></script>

<script>
	var pivot = $("#pivotContainer").flexmonster({
		toolbar: true,
		licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
	});
</script>

Step 2: Setup Data Compressor on the server

First of all, you need to install Flexmonster Compressor. Please download it on nuget.org or run the following command in the Package Manager Console:

Install-Package Flexmonster.Compressor

Then add the appropriate database driver to your project. Below is the connection and query sample for MySql:

string connetionString = "server=localhost;database=XXX;";
string sql = "SELECT * FROM YYY";
MySqlConnection sqlConnection = new MySqlConnection(connetionString);
sqlConnection.Open();
MySqlCommand command = new MySqlCommand(sql, sqlConnection);
DbDataReader dataReader = command.ExecuteReader();

The following line of code will convert DbDataReader to compressed Stream:

Stream inputStream = Compressor.CompressDb(dataReader);

Now, you can create a response from the Stream. For simple cases, it is enough to read all content:

StreamReader reader = new StreamReader(inputStream);
string output = reader.ReadToEnd();

Step 3: Enable cross-origin resource sharing (CORS).

By default, browser prevents JavaScript from making requests across domain boundaries. CORS allows web applications to make cross-domain requests. Here are some useful links explaining how to setup CORS on your server:

Step 4: Configure report with your own data

Now it’s time to configure Flexmonster Pivot Component on the web page. Let’s create a minimal report for this (replace filename and other parameters with your specific values):

var pivot = $("#pivotContainer").flexmonster({
	toolbar: true,
	report: {
		dataSource: {
			dataSourceType: "ocsv",
			/* URL to the Data Compressor .NET Core */
			filename: "http://localhost:55772/api/flexmonster/get"
		}
	},
	licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});

Launch the web page from browser — here you go! A pivot table is embedded into your project.

Examples

Saving to file

string connetionString = "server=localhost;database=XXX;";
string sql = "SELECT * FROM YYY";
MySqlConnection sqlConnection = new MySqlConnection(connetionString);
sqlConnection.Open();
MySqlCommand command = new MySqlCommand(sql, sqlConnection);
DbDataReader dataReader = command.ExecuteReader();

Stream inputStream = Compressor.CompressDb(dataReader);
FileStream fileStream = File.Create("data.ocsv");
inputStream.CopyTo(fileStream);
fileStream.Dispose();
