WITH cte AS ( SELECT COALESCE (State, Country, Region) AS Place, SUM (ValueX) AS ValueX, SUM (ValueY) AS ValueY FROM MY_TABLE GROUP BY GROUPING SETS (Region, Country, State) ) SELECT T1.Place, T1.ValueX, T1.ValueY, T2.SEC FROM cte AS T1 . SELECT ID, SUM(VALUE1 + VALUE2 + VALUE3) FROM tableName GROUP BY ID. Creating subsets allows you to compute values over just that specified sub-group of rows. Snowflake minimizes potential overflow in the output (due to chained division) and loss of scale by adding 6 digits to the scale of the numerator, up to a maximum threshold of 12 digits, unless the 500 WAIVED 120 #N/A 50. 17.6K Followers. In dynamic array Excel 365 and 2021, a normal formula will work fine as shown in the screenshot: The easiest way to sum multiple columns based on multiple criteria is the SUMPRODUCT formula: As you can see, it's very similar to the SUM formula, but does not require any extra manipulations with arrays. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? If the cast A1 B1 E1 F1 H1, 1. The idea is to write a separate SUMIF formula for each of the columns you want to sum, and then add up the results: A practical implementation looks as follows: =SUM(SUMIF(A2:A10,H1,C2:C10), SUMIF(A2:A10,H1,D2:D10), SUMIF(A2:A10,H1,E2:E10)), =SUMIF(A2:A10, H1, C2:C10) + SUMIF(A2:A10, H1, D2:D10) + SUMIF(A2:A10, H1, E2:E10). in Using Window Functions. More precisely, a window function is passed 0 or more expressions. Thanks for your quick reply Alexander! frame, make it an explicit window frame. .
