MariaDBERRORNotableGIS / GeometryHIGH confidence
SRS is not Cartesian (alternate context)
Production Risk
Medium — DDL fails; spatial index cannot be created.
How to reproduce
trigger — this will error
trigger — this will error
ALTER TABLE t1 ADD SPATIAL INDEX (geom_col) WHERE ST_SRID(geom_col) = 4326;
expected output
ERROR 3282 (HY000): Function requires a Cartesian spatial reference system.
Fix
Use SRID 0 for spatial indexes
Use SRID 0 for spatial indexes
ALTER TABLE t1 MODIFY COLUMN geom_col GEOMETRY SRID 0 NOT NULL; ALTER TABLE t1 ADD SPATIAL INDEX (geom_col);
Why this works
Spatial indexes in MySQL 8.0 work with both Cartesian and geographic SRS.
