![]() However, you have to be careful when you use them on a list, because most of the times, query folding might happen, and then you get the same number for every row in the list after loading it into Power BI. There are two other random functions in Power Query: Number.Random and Number.RandomBetween, they both give you a random number. If you don’t like this to happen, and you want the list to be generated randomly only once, and doesn’t change with every function call, then you can specify the seed parameter: It means for every step, you will see the random list changing! You might also want to add a row number to the table, here is how you can do it: Under Add Column -> Index ColumnĪnd here is the dataset loaded into Power BI:Ĭhanging the Random List on Every Function Callīy default when you use List.Random with one parameter, it will recreate the list of random numbers after each function call. Now, we have a table with values up to 1000 Let’s say, for example, I want this to be a random number up to 1000. If you want this to be on a higher value, you can always multiply it with something. the table output now should have one column:Īs you see, the random number generated is between zero and one. When you convert a list to a table, you can split it based on a delimiter, which is not what we want here, so just click OK, on the “To Table” dialogue box. You can convert this list now to a table: You can even use this for generating a list of 10 million numbers! However, be careful when you load all that data into Power BI! It might consume all the memory □ In the Formula Bar, use the expression below = List.Random(10) If you don’t see the formula bar in Power Query Editor, this is where you can enable it: In the View tab, check the Formula Bar: To use this function to create a sample list, it is always easier to start from a blank query. You just specify the number of random numbers that you want to generate:įor example, if I want to create a list of ten random values, it would be List.Random(10). List.Random is one of those functions, which is very helpful. There are some functions that help with creating a random value. If you like to learn more about Power BI, read Power BI book from Rookie to Rock Star. You can use the generated output for building a sample dataset to work on with Power BI Desktop. In this short blog post, I’ll explain how to create this random list. There is a great and quick way that you can create a random list of numbers in Power BI using Power Query. The main objective of this German number is to deter telemarketers and the likes.I’ve been asked from one of my friends who were trying to create a random dataset for his presentation. There's also a landline number, but be prepared to explain why your number is based in the Bielefeld area:Īctually, if your goal is to disappear, this particular number is quite fitting since, much like the number itself, Bielefeld doesn't actually exist. You can preview Frank’s message on the site it’s German, of course. Because it's neutral in terms of location and message, you can use it in all sorts of situations, for example in official forms. Next time you feel forced to share your phone number, let Frank answer the phone for you.įrank will politely tell the person calling that you do not wish to be contacted by them. Since cell phone prefixes in Germany, like in Australia, are provider-specific, this number won't give away a location. Add +49 and kill the leading 0 if you're giving one of the numbers below to someone outside of Germany.
