MySQL raises ER_GIS_INVALID_DATA (SQLSTATE 22023) when a spatial function receives an argument that is not a valid geometry value.
ER_GIS_INVALID_DATA appears when MySQL cannot parse the geometry you pass to a spatial function. Validate WKT/WKB, ensure SRIDs match, and reinsert the geometry with ST_GeomFromText to resolve the issue.
ER_GIS_INVALID_DATA
MySQL throws the ER_GIS_INVALID_DATA error when a spatial routine like ST_Length or ST_Contains receives geometry input that the server cannot interpret as valid GIS data. The error stops the query to prevent corrupt or ambiguous spatial results.
This condition first appeared in MySQL 5.7.5 when spatial functions were rewritten for GIS standard compliance. It returns SQLSTATE 22023, flagging an invalid parameter value.
The most frequent cause is malformed Well Known Text (WKT) or Well Known Binary (WKB) strings supplied to geometry constructors. Missing commas, extra parentheses, or misspelled geometry types break parsing.
Another common trigger is mixing SRIDs or supplying geometry without an SRID to functions that require one. MySQL validates that all operands share the same spatial reference system.
Storage layer corruption also manifests as invalid geometry. If a BLOB column that holds spatial data is truncated or encoded incorrectly, any read attempt raises ER_GIS_INVALID_DATA.
First, locate the exact row and column generating the error by selecting the geometry as WKT. Use ST_AsText to expose the raw string.
Next, validate and, if needed, rebuild the geometry with ST_GeomFromText or ST_GeomFromWKB, supplying the correct SRID.
If multiple rows are affected, script an update that reconstructs geometries in place or migrates them to a clean table.
When importing shapefiles, load data often stops at the first invalid row. Bypass the failure by using the --skip-failing option, then correct the bad records one by one.
If you upgraded from an older MySQL version, legacy geometries might lack SRIDs. Update them using ALTER TABLE ... MODIFY COLUMN ... SRID = n followed by an UPDATE that sets ST_SRID.
Always validate geometry on ingest with ST_IsValid and reject rows that fail. Wrap bulk loads in stored procedures that call these checks.
Standardize on a single SRID per table and document it in your schema. Enforce consistency with CHECK constraints in MySQL 8.0.16+.

ER_GIS_UNKNOWN_ERROR (3038) surfaces when geometry parsing fails for unknown reasons. The fix process mirrors ER_GIS_INVALID_DATA: validate, rebuild, and reinsert.
ER_GIS_UNSUPPORTED_ARGUMENT (3039) indicates that a geometry subtype is not supported by the called function. Convert the geometry to a compatible type or switch functions.
Extra commas, incorrect parentheses, or misspelled geometry types break the WKT parser and trigger ER_GIS_INVALID_DATA.
Spatial functions that compare or transform geometries require identical SRIDs. Discrepancies cause validation failure.
Truncated BLOBs or file-system corruption can damage stored geometries, making them unreadable.
Older MySQL versions allowed zero-area polygons and SRID-less data that current versions now reject.
Thrown when geometry parsing fails for unspecified reasons. Validate and rebuild the geometry similar to ER_GIS_INVALID_DATA.
Occurs when a spatial function receives a geometry subtype it cannot handle. Use a compatible function or convert the geometry.
Raised when MySQL cannot find an encoder for the given geometry type. Confirm server build includes the needed spatial libraries.
No. It can also stem from simple format mistakes like extra commas in WKT or missing SRIDs.
Use ST_IsValid in a staging table or run ogr2ogr with the -makevalid flag to cleanse data prior to import.
Strict mode does not affect spatial validation. MySQL validates geometry regardless of SQL mode.
Yes. Galaxy’s editor highlights failing rows, and its AI copilot can rewrite faulty INSERT statements with proper ST_GeomFromText syntax.
