![]() Select tables in DirectQuery modeĪfter selecting tables, click on Load. In the Navigator window, you can select some tables from the AdventureWorksDW database, such as DimDate, and FactInternetSales. Please note that data sources which support DirectQuery, Also, support Import Data (Any data sources support Import Data). Also, you need to put your server name If your SQL Server instance is the default instance on your machine, you can use (.) for the server. The very first query you will get when connecting to SQL Server data source includes an option for choosing the Data Connectivity mode. Open a Power BI Desktop and start with the Get Data from SQL Server. We’ll only talk about the Power BI part of the example So, I’m not going to explain how to do that. This post is not about installing and configuring SQL Server or setting up a database on it. Then set up AdventureWorksDW database on it. ![]() You can download the SQL Server Developer Edition from here: How to Use DirectQueryįor running this example, you need to have a SQL Server instance installed. To view the up-to-date list always use this link. This list may change, with every new update in Power BI connectors, some new data sources may be added to the DirectQuery supported lists of Power BI. Here are some of the data sources supported through DirectQuery Usually, data sources that are relational database models, or have a modeling engine, support DirectQuery mode. You cannot create a connection as a DirectQuery to an Excel File. Unlike Import Data which is supported in all types of data sources, DirectQuery is only supported by a limited number of data sources. Anytime you see a visualization in a report the data comes straight from a query sent to the data source. DirectQuery means Power BI is directly connected to the data source. DirectQuery doesn’t consume memory because there will be no second copy of the data stored. If you remember from the previous post, Power BI loads data into memory (when Import Data or Scheduled Refresh is used as a connection type). What is DirectQuery?ĭirectQuery is a type of connection in Power BI which does not load data into the Power BI model. DirectQuery is different from another type of connection which I’ll talk about it in the next post named Live Connection. This type of connection is only supported by a limited number of data sources, and mainly targets systems with a huge amount of data. In this post, you’ll learn about the second type of connection named DirectQuery. With that said though, thank you for your work on this and just please be more cognizant of the message you put out as it might turn others away.In the last post, you learned about Import Data or Scheduled Refresh as a connection type. I get its open source and we aren't paying for the software outside of donations, so I'm not going to bitch too much about it, but at the same time, that sort of mentality and dismissal is not cool and really puts a bad taste in the mouth of those that might be newer to open source software and stumbling upon this thread for the first time. There are a plethora of reasons to need to open multiple tables in different tabs, and just because you can't think of any you feel are valid, is no reason to dismiss the suggestion and a feature that literally just about any other DB management tool offers by default. Not cool to even suggest that to be honest. Imagine in an IDE or VS Code you could only have one tab/file open at a time, asked for the ability to open multiple things at once, and they came back and told you to learn the system better and just open up multiple instances of VS Code or your IDE to see different files. Your suggestion of just opening another instance of Heidi seems a bit disingenuous. Literally just about every other DB software has the ability to open multiple tables at once under different tabs so we don't have to write queries just to view basic data and keep going back into the explorer to open another table we might need to look at.
