Hi all,

I have a simply question about a measurement.

if you have a table like that :

Name;post;value
stef;A;30
stef;B;15
stef;C;10
joan;A;40
joan;B;15
joan;C;5
...


and you want to add a line for each name that represents the diffrence between
A-C values and that I want to name D.

Name;post;value
stef;A;30
stef;B;15
stef;C;10
stef;D;20 <= substract from A-C
joan;A;40
joan;B;15
joan;C;5
joan;D;35 <= substract from A-C
...


without transposing, how you do that ?


Stéphane.
