…aphic with MySQL >= 8 (fixes qgis/QGIS#55463) It seems spatial predicates are not directly usable when using geographic SRS. For some reason select MBRIntersects(ST_GeomFromText('POLYGON((-90 -90, 90 -90, 90 90, -90 90, -90 -90))', 4326), ST_GeomFromText('POINT(0 0)', 4326)); returns true as expected But select MBRIntersects(ST_GeomFromText('POLYGON((-179 -89, 179 -89, 179 89, -179 89, -179 -89))', 4326, 'axis-order=long-lat'), ST_GeomFromText('POINT(0 0)', 4326)); returns false !!!! And select MBRIntersects(ST_GeomFromText('POLYGON((-179 -89, 179 -89, 179 89, -179 89, -179 -89))', 32631), ST_GeomFromText('POINT(0 0)', 32631)); returns true as expected Consequence, we need to force a projected SRS for the arguments of MBRIntersects()

returns true as expected
But
returns false !!!!
And
returns true as expected
Consequence, we need to force a projected SRS for the arguments of MBRIntersects()
