[Qgis-user] Problems to create new columns through two tables

[Daniel Alejandro Montecinos Rubilar]

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
