[Qgis-user] Dealing with tables that have composite keys.

[Bob and Deb]

Hello qgis-users,

It has been a while since I've looked at QGIS, but I'm excited to hear
about the new stuff in QGIS3.  I'm hoping that it will help me with an old
problem that has kept me from fully embracing QGIS.

If I have a table called Sample_Data with attributes (official_name,
sample_id, top_depth, bottom_depth) and another table called
Soil_Indices_Lab with attributes (official_name, sample_id, parameter_name,
parameter_value, parameter_units), and I want to use QGIS Relations using
(official_name,sample_id), I run into this issue (
https://issues.qgis.org/issues/9531).  Can anyone tell me if QGIS3 will
address this problem or if there are other features in QGIS3 that will
allow me to work around this limitation?

Thank you,

Bob
