ER_GIS_DIFFERENT_SRIDS is raised when a MySQL spatial function receives two geometry values that have different SRID identifiers.
ER_GIS_DIFFERENT_SRIDS occurs when MySQL spatial routines receive geometries stored in different SRIDs. Align the SRID of every geometry column or literal with ALTER TABLE or cast them with ST_SRID or ST_Transform to eliminate the mismatch and let the query run.
ER_GIS_DIFFERENT_SRIDS
MySQL throws ER_GIS_DIFFERENT_SRIDS when a spatial function such as ST_Intersects, ST_Distance, or ST_Within is called with two geometry operands that carry different Spatial Reference System Identifiers (SRID).
Spatial routines require operands to reside in the same coordinate system so that distances, areas, and relations are computed correctly. When SRID values differ, MySQL aborts the statement to prevent incorrect calculations.
Fixing the mismatch is important because silently converting or ignoring SRIDs would compromise spatial accuracy, leading to faulty analytics or geospatial application bugs.
The error surfaces most often when geometry columns were created with different SRIDs or when literals are constructed without explicitly setting SRID using ST_GeomFromText().
Migrations, data imports, and third-party tools can also introduce mixed SRIDs if they default to 0 or EPSG:4326 while the existing table uses another system.
First identify the SRID of each geometry with the ST_SRID() function, then align them by updating data, altering column definitions, or casting operands on the fly.
Stable production fixes alter the column SRID so that all future inserts follow the same reference system. Quick ad-hoc fixes cast literals or columns inside the query.
Queries joining a WGS-84 point column (SRID 4326) with a planar metric column (SRID 3857) fail until you convert one column to match the other.
Imported shapefiles often default to SRID 0. Update those rows to the correct SRID to unblock spatial predicates.
Standardize on a single SRID per database or schema, document it, and enforce it with check constraints or BEFORE INSERT triggers.
During ETL, always set SRID when calling ST_GeomFromText or ST_PointFromText. Validate incoming files with ogrinfo or similar tools before loading.
ER_GIS_INVALID_DATA (3034) occurs when geometry WKB or WKT is malformed, not just mismatched. Validate geometries with ST_IsValid.
ER_GIS_UNSUPPORTED_ARGUMENT (3026) appears when a spatial function is called with wrong argument types. Cast to the expected geometry subtype to resolve.
Two tables were created with different SRIDs and later joined in a spatial comparison.
Bulk loads that omit SRID leave rows at 0, diverging from the target table.
Developers create points with ST_GeomFromText without setting the third SRID argument.
Migrations add new geometry columns using a new SRID without updating the legacy columns.
Raised when a spatial function receives mismatched argument types. Cast geometries to compatible subtypes.
Occurs when geometry binary text or WKB is malformed. Validate inputs with ST_IsValid.
Different code number but similar cause - indicates invalid geometry rather than SRID mismatch.
Setting SRID without transformation only tags the geometry. Use ST_Transform to reproject coordinates safely.
No. MySQL enforces matching SRIDs to guarantee spatial correctness. Always align or convert geometries.
SRID 0 means undefined reference system. Mixing defined and undefined SRIDs triggers the error.
Galaxy highlights SRID metadata in autocomplete and warns when spatial joins mix mismatched SRIDs, preventing faulty queries before execution.
