<p class="xmsonormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"> </span><o:p></o:p></p>
<p class="xmsonormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">in a QGIS project I have a PostGIS polygon layer where I joined two tables (from PostgrSQL DB). Then I created a virtual layer, containing all the attributes of the polygon
layer and all the attributes of the joined tables. This works well so far.</span><o:p></o:p></p>
<p class="xmsonormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"> </span><o:p></o:p></p>
<p class="xmsonormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">When I close the QGIS project an open it again, the virtual layer attribute table first doesn’t show the joined attributes. They only appear, when I save the virtual layer again
with the same select statement.</span><o:p></o:p></p>
<p class="xmsonormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Does anyone have any tips on how to ensure that the virtual layer permanently retains the joined attributes?</span><o:p></o:p></p>
