Why are QGIS joins always inner from the join table?
QGIS joins are always inner from the join table’s perspective; the output attribute table will not include non-matching records from the join table. Same with ArcMap Selections:
How to join multiple records to single feature in QGIS?
Open the spatial located data as a layer in QGIS, then you select all the records in the attribute table in QGIS (clear selection, invert selection) and copy these into a new sheet in LibreOffice Calc. You will find the first field is WKT, which is a description of the feature which can be universally used in GIS.
Which is the latest version of QGIS for one to many relations?
In QGIS 1.7 there is a new engine for Joins (you find it in the vector properties). Geometryless tables can now be added to a project like any other (vector) layer. Starting at version 2.2 QGIS supports one-to-many relations.
Where do I find related records in QGIS?
Starting at version 2.2 QGIS supports one-to-many relations. Define them in the Project Properties though, not Vector Layer Properties. And then related records will appear in the layer’s Attribute Table or Identify Results via the form. See answer and link to good guide here.
How does parent / child relation work in QGIS?
The parent/child relation is displayed in the attribute form and let you easily update both at the same time (in your case a CSV won’t be editable, you will need to convert to another format if you need to edit from QGIS). See link at the bottom for more information on how it work
How to establish a relation in QGIS with Fulcrum?
Select your two Referencing Fields and click OK. With the relationship established, use the QGIS Identify tool to select one of the parent items.

What kind of data can I use with QGIS?
QGIS natively supports all of Fulcrum’s open data formats, including CSV, shapefile, SQLite/SpatiaLite, and geojson. For this guide, I’ll be using SQLite, a file-based database format that’s well-supported and simple to work with.
