The reason is that the dimensions of sum_range are determined by Excel automatically based on the dimensions of the range argument. 5, 5, blank, blank, blank, total = 5x5 Creating subsets allows you to compute values over just that specified sub-group of rows. For non-window functions, all arguments are usually passed explicitly to the function, for example: Window functions behave differently; although the current row is passed as an argument the normal way, the window is passed through a separate clause, called Rank salespeople on revenue (sales), from highest to lowest.

Snowflake minimizes potential overflow (due to chained multiplication) by adding the number of digits in the scale of both inputs, up to a maximum threshold of 12 digits, unless either of the inputs has a scale larger than 12, in which case the larger . In other words, assuming a division operation with numerator L1.S1 and denominator L2.S2, the maximum number of digits in the output are calculated as follows: If the result of the division operation exceeds the output scale, Snowflake rounds the output (rather than truncating the output). The exceptions include: Because rank-related window functions are order-sensitive, the ORDER BY clause is required, not optional. This is mathematics.

Thankfully in Snowflake this is unnecessary as we have the pivot clause available, but to use this clause we do first have to reduce the table to just the row column (remains as rows), pivot column (distinct values spread into multiple columns), and value columns (populates the cell values). A function can be both a rank-related function and a window-frame function. Though we have to update it if anything changes in the data set.Nice analysis, especially with the sumproduct and sum functions. I hope itll be helpful.
