counting commun and different values

[taz803]

I have two columns (RE and RE_D) I want to compare the values ​​and after do a count on the common values ​​and count on the differenetes values ​​and display in a table.

My table should contain:

RE | RE_D | count(commun values) |  count(different values)

how can i hundle it ? , Thanks a lot

Common values: Sum(If(RE = RE_D, 1, 0))

Different values:  Sum(If(RE <> RE_D, 1, 0))
