Re: [Qgis-user] Compare and the most value

[Bia]

2 questions:
1) in the field calculator as I can, for example, find the greatest value
of a column?

2) Can I compare different tables (different shapfiles) to for example
obtain a value of contamination concentration in tables with different
concentrations and dates?

Tanks!
