I have the following table. Now I want to count the amount of each value in this table.

value count
1 1
-1 1
2 1
3 1

-1 and 1 should be seen as 1, so the output should be

value count
1 2
2 1
3 1

Does someone know a quick fix?

Grouping by value, and making such values the absolute value so you ignore the negative sign:

SELECT
ABS(VALUE) VALUE, COUNT() COUNT
FROM
table
GROUP BY 
ABS(VALUE)
