There are plenty of ODBC drivers, both open source and commercial, for almost any data source. For users who are not familiar with the ODBC technology, I’ll briefly explain what it is: ODBC is a standard application programming interface that allows applications such as Power BI, Microsoft Excel, and hundreds of other apps that support ODBC connectivity, to access data in various databases and cloud applications. By cloud applications, I mean the likes of MailChimp, Salesforce, BigCommerce, etc. The driver serves as an intermediary between the data source and the application you want to pull the data into, and is really easy to install and configure.

I’ll show you how to load data from the PostgreSQL database into Power BI with the help of the corresponding ODBC driver, but the steps covered here are almost the same for other databases, feel free to replicate them for other data sources.  For the purpose of this post, I’ve created a ‘cars’ table in my Postgres database and populated it with mock data. 

 

In Power BI Desktop, click Get Data, then select Other > ODBC category. Click Connect.

In the From ODBC dialog box, expand the Data Source Name (DSN) drop-down list and select the DSN that you’ve configured for your data source. Optionally, you can enter a SQL statement to execute against the ODBC driver in the Advanced options -- for example, if you want to filter or sort the data in the table rather than to load the entire dataset. Click OK.  If your data source is password-protected, Power BI will prompt you for the username and password. Type them into the respective fields and click OK.

With the above SQL statement executed, I’ve received only one record in the results.

If I don’t specify any SQL statement, Power BI will retrieve the metadata from the Postgres database and offer you to select the table to load. You can preview the data by selecting the needed table.

Click Load to import the data into Power BI to work on it. Power BI doesn’t display the loaded data in a grid by default, it only creates models and identifies relationships in the data, which it caches in-memory for reports. 

 

Let’s say we want to create a line and stacked column chart that will display how many car models each manufacturer has in our database. In the right pane, select the needed columns - id, manufacturer, and model, and the needed chart type.

As a result, we get the following chart, we get the following chart.

An ODBC driver takes over the task of data retrieval, allowing you to concentrate on the data analysis.

Importing SQL Server Data into Power BI Through an ODBC Connection

Power BI is a polular business intelligence solution which is comprised of services, apps, and connectors that allow you to pull in raw data from various sources and create meaningful reports. To connect Power BI to a data source such as SQL Server, you can use a corresponding ODBC driver.


This tutorial explores how to connect to SQL Server and import data into Power BI Desktop using an ODBC driver. It is assumed that you have already installed and configured a DSN for ODBC driver for SQL Server.

  1. Run Power BI Desktop and click Get Data.
  2. Select the Other category in the Get Data dialog box, then select ODBC. Click Connect to confirm the choice.
  3. In the From ODBC dialog box, expand the Data Source Name (DSN) drop-down list and select the previously configured DSN for SQL Server
  4. If you would like to enter a SQL statement to narrow down the returned results, click the Advanced options arrow, which expands the dialog box, and type or paste your SQL statement.
  5. Click OK. If your data source is password-protected, Power BI will prompt you for user credentials. Type your Username and Password in the respective fields and click.
  6. Now you should see the data structures in your data source. You can preview the contents of the database objects by clicking on them.
  7. To load the SQL Server data into Power BI for analysis, select the needed table and click Load.

Chris Webb's BI Blog

A few weeks ago I received a great tip from Simon Nuss about a Power Query feature relating to ODBC data sources that I hadn’t seen before (although it’s in Power BI Desktop and Excel 365, so it can’t be that new) and which is potentially important for the performance of data refresh and of the Power Query Editor’s preview pane. It’s only visible if you click “Advanced options” when creating your ODBC data source:

image

It’s the “Supported row reduction clauses” option:

image

What does it do? Well, first of all let’s see what happens if you don’t set it. Let’s say you have an ODBC data source that uses the Microsoft ODBC Driver for SQL Server to connect to the Adventure Works DW database. If you create a new query that uses this data source to get the contents of the DimDate table it works pretty much as you’d expect; here’s the M code:

let Source = Odbc.DataSource( "dsn=Test SQL", [HierarchicalNavigation=true] ), #"Adventure Works DW_Database" = Source{ [Name="Adventure Works DW",Kind="Database"] }[Data], dbo_Schema = #"Adventure Works DW_Database"{ [Name="dbo",Kind="Schema"] }[Data], DimDate_Table = dbo_Schema{[Name="DimDate",Kind="Table"]}[Data] in DimDate_Table

image

However, if you look in Profiler when the contents of the Preview window is refreshed, you’ll see that the Power Query engine is running a query that gets the entire contents of the table:

image

Obviously, if you are connecting to a big table this could make the Power Query Editor slow. What’s more, as this blog post shows, the Power Query Editor only actually wants to display 1000 rows and the fact that the query is requesting all the rows from the table suggests that even basic query folding is not happening on this ODBC data source.

Now let’s see what happens if you do select something from the “Supported row reduction clauses” dropdown. As the screenshot above shows, there are four values in the dropdown that relate to the form of SQL supported by your ODBC source to only get the first N rows from a table. If you don’t know which one to choose you can click the Detect button and it will select one for you. In this case I selected TOP:

image

Having done this, when you connect to the same DimDate table, you’ll see that now the Power Query Editor is only requesting the top 1000 rows from the table:

image

Also, if you look at the M code for the query, the Odbc.DataSource function has the as-yet undocumented SqlCapabilities option set in its second parameter,

Odbc.DataSource( "dsn=Test SQL", [HierarchicalNavigation=true, SqlCapabilities=[LimitClauseKind=LimitClauseKind.Top] ] )

Actually it’s not quite undocumented because it is mentioned here as something that is only available if you’re using Odbc.DataSource in a custom connector; obviously things have changed.

Setting this option can make a big difference to the responsiveness of the Power Query Editor when you’re working with large tables and/or slow data sources – I saw this myself this week when working with one of my customers. It’s also going to be important if you use the Keep Rows/Keep Top Rows button on the ribbon or the Table.FirstN() M function; I suspect there are other, more obscure, reasons why it might speed refresh up even if you aren’t filtering the rows of the table but I’m not 100% sure.

One last thing to mention is that there is another undocumented function which is what, I think, the Detect button in the screenshots above uses to find out how to set the SqlCapabilities option. It’s called Odbc.InferOptions and it can be used like so:

Odbc.InferOptions("dsn=Test SQL")

This function returns a record containing a field called LimitClauseKind that tells you the type of limit clause that is supported:

Here’s a list of the possible LimitClauseKind values I found using #shared:

Now discussing:

Power BI has many data connectors you can use to connect to your Data Source. If your Data Source is not listed from Get Data on Power BI Desktop, you can use one of the following generic data interfaces:

  • ODBC
  • OLE DB
  • OData
  • REST APIs
  • R Scripts

While working on a recent project,  I see that after adding an ODBC Data Source to Power BI Gateway using the same connection string on Power BI Desktop, the Gateway still shows ” Not configured correctly” similar to the screenshot below:

In this post, we will discuss how to configure and connect to ODBC data source(On-Premises) on Power BI Desktop and refresh on Power BI Service

There are 4 steps to complete the process

  1. Install the driver for the data source and configure the ODBC Data source
  2. Connect to the ODBC source from Power BI Desktop
  3. Add the Datasource to Power BI Gateway
  4. Publish the report to Power BI service and map the Data source to the Gateway.

Step one: Install the ODBC driver for the data source and configure the ODBC Data source

Ensure that the bit for Power BI Desktop and the driver are the same (64 bit recommended).

For this example, I am using Access database.

To create a DSN for an Access database:

  • Open ODBC data source from control panel
  • Select System DSN- for multiple users
  • Select Microsoft Access driver (*.mdb)
  • The ODBC Microsoft Access Setup dialog box opens.
  • The Select Database dialog box opens.
  • Browse to the drive where your data is located

Your Access database DSN is now created.

Step two: Connect to the ODBC source from Power BI Desktop

Ensure that you are using updated version of Power BI Desktop.

To connect to ODBC data source that has been configured on Power BI Desktop:

  • Select Get Data ->Other -> ODBC – Select Connect

On Power BI Desktop while creating a DataSet based on ODBC, you must select ‘(None)’ from the Data Source Name (DSN) dropdown and paste your connection string to ‘Connection String’ textbox under Advanced options section to see the gateway configured correctly on Power BI service after adding the data source to the Gateway.

  • Change the DSN to None and add a connection string.
    As an option, you can also specify a SQL statement to execute against the ODBC driver.
  • Select OK and authenticate to load or transform your data

Step three: Add the Datasource to Power BI Gateway

Ensure that you are using the updated version of Power BI Gateway.

To add the data source to the gateway:

Go to Gateway Management on Power BI Service

  • Click Add Data source -> Select ODBC for data source type
  • Add the same connection string and Authentication method on Power BI Desktop

Step four:Publish the report to Power BI service and map the Data source to the Gateway.

To map the data source to the gateway:

  • Go to settings -> Dataset
  • Expand Gateway connection
  • Select Maps to and select the name of the data source

You can now do On demand and scheduled refresh.

Happy reporting 🙂
