Hello I want to create a new column in QGIS from a cross-information of two tables. The first table are communes of my country and the second are some electrical faults plotted as points. Then I want to create a new column in table 1, by means of the following logic:
NewColumn = Sum (column_value2_ of_table2) I have been using MapInfo for a long time and recently I occupy QGIS with the intention of changing and I was getting convinced until I could not perform this operation, which in MapInfo was very easy with SQL queries. I already appreciate your comments Sincerely, Daniel Montecinos Rubilar Electrical Civil Engineer
