Select rows where values of one column are equal to each other in powerpivot

Question

I want select a,b,c,d,e,f,g,h,i from a big table"Data" where column"f" values are equal to each other and column"a" value is biggest and column"f" values are not equal to each other.

Answer 1

Use GROUP BY clause.

GROUP BY aggregates records based on column value equality.

For example:

SELECT f, max(a) as a
FROM yourtable
GROUP BY f;

You can use this as a subquery to select records from your table with the result's f and max(a) values.
