I hope this little script can help in your DAX expressions, if you have any questions, feel free to write a comment below. This method is usually more useful when the value you want to extract is closer to the end of the string rather than the start. You can implement the Reverse substring as below: Reverse Substring = LEFT( For example, for “Reza Rad”, with ReverseSubstring(3,2), means “Ra”. For example, ReverseSubString (N, M) means to start from N which is the index from the right end of the string and extract M characters. Sometimes you want substring to start from the end of the text. Using the MID function, you just specify the starting index, and the length of characters to extract, similar to substring in many other languages. There is an easier way to do substring too, using MID function MID = MID(DimCustomer,5,7) if you want to start from the beginning of the text, use zero here.ģ, in the expression above, is the length of the output from the starting index. Will produce characters starting from index 1 for the length of 3.ġ, in the expression above, is the starting index. This can be implemented in DAX in different ways, this is one of the methods: Substring = LEFT( Substring means saying from character indexed N, extract M characters: Substring (N,M) Considering that the first character is index 0. Substring means getting part of a string, for example from “Reza Rad”, if I want to get the start starting from index 2, for 4 characters, it should return “za R”. There is a very simple way of doing it, which I am going to explain in this post. Substring is one of the most common functions in many languages, However, there is no function named Substring DAX.
