Lets look at the rank function, one that is relevant to ordering. If you wish to maintain the same values each time, you can simply enter a seed value as the parameter of the RANDOM function. Here, we have the sum of quantity by product. A seed can be Specifies whether to sample based on a fraction of the table or a fixed number of rows in the table, where: probability specifies the percentage probability to use for selecting the sample. I have used the code contained below to create date and time scaffolds for several clients for various reasons, such as populating records between the "CreateDate" and "CloseDate" of a data point. Manage Settings It's not an easy query to break down, but we can construct a simpler table. We can see this in our first example now, for which we will simply output the same value five times.
