Upload data to a Power BI real-time

This blog will show you how to load data into a Power BI real-time data set using Powershell.
The following code load to a Power BI dataset from a table in the adventureworks database

#Variables - details of the connection, stored procedure and parameters
$connectionString = "server=localhost;database='Adventureworksdw2017';trusted_connection=true;";
$storedProcedureCall = [your store procedure;

#SQL Connection - connection to SQL server
$sqlConnection = new-object System.Data.SqlClient.SqlConnection;
$sqlConnection.ConnectionString = $connectionString;

#SQL Command - set up the SQL call
$sqlCommand = New-Object System.Data.SqlClient.SqlCommand;
$sqlCommand.Connection = $sqlConnection;
$sqlCommand.CommandText = $storedProcedureCall;


#SQL Adapter - get the results using the SQL Command
$sqlAdapter = new-object System.Data.SqlClient.SqlDataAdapter
$sqlAdapter.SelectCommand = $sqlCommand
$dataSet = new-object System.Data.Dataset
$recordCount = $sqlAdapter.Fill($dataSet)

#Close SQL Connection
$sqlConnection.Close();

#Get single table from dataset
$data = $dataSet.Tables[0]

$endpoint = [your dataset url]

#Loop through each row of data and create a new file
#The dataset contains a column named FileName that I am using for the name of the file
foreach($row in $data)
{

$payload = @{
"ProductKey" =$row.Item("ProductKey")
"SalesAmount" =$row.Item("SalesAmount")
}
Invoke-RestMethod -Method Post -Uri "$endpoint" -Body (ConvertTo-Json @($payload))
write-Host $row.Item("ProductKey")
}
