In QGIS 3.6.3 I'm trying to create a Virtual Layer obtained by merging 12 shapefiles (with the columns named and ordered in the same way) using the expression
SELECT * FROM _January, _February, _March, _April, _May, _June, _July, _August, _September, _November, _October, _December
but the software crashes.
If I wanted to create a Virtual Layer by taking data from a single column called
"TEST", how can I modify the expression? I could not find the correct form.
