I have the following structure

Column1 Column2
Foo     100
Baa     200

How can I have a value that is the sum of all column2 values where its column1 value is equal to Foo?

CodePudding user response：

a lot of solutions for this like:

=SUMIF(A1:A; "Foo"; B1:B)

=SUMIFS(B1:B; A1:A; "Foo")

=INDEX(SUM((A1:A="foo")*B1:B))

=SUM(FILTER(B1:B; A1:A="Foo"))

=SUMPRODUCT(B1:B*(A1:A="Foo"))

=QUERY(A1:B; "select sum(B) where A = 'Foo'")
