MySQL raises ER_BOOST_GEOMETRY_UNKNOWN_EXCEPTION when a spatial function triggers an unexpected Boost.Geometry exception.
ER_BOOST_GEOMETRY_UNKNOWN_EXCEPTION (error 3043, SQLSTATE HY000) signals that a MySQL spatial function crashed inside the Boost.Geometry library, usually because the input geometry is invalid or its coordinates exceed allowable ranges. Validate and repair the geometry or upgrade to a patched MySQL build to fix the issue.
ER_BOOST_GEOMETRY_UNKNOWN_EXCEPTION
Error 3043 appears when a spatial function in MySQL 5.7.5 or later crashes inside the Boost.Geometry engine and bubbles up as an "unknown exception." The message includes the function name, helping identify the failing query.
The error belongs to SQLSTATE HY000 (general error) and halts the current statement, so reads and writes relying on the result fail until the offending data or code path is fixed.
The error surfaces during calls to ST_Contains, ST_Intersects, ST_Buffer, ST_IsValid, and other geometry functions. It typically follows malformed WKT, self-intersecting polygons, or coordinate values beyond SRID limits.
Developers upgrading from pre-5.7.5 often see 3043 after enabling strict spatial checks or migrating legacy GIS data that never passed validation.
Queries that hit 3043 abort, causing missing analytics, failed ETL jobs, or broken location features in production apps. Left unresolved, it can mask deeper data-quality issues and degrade user trust.
Invalid geometry topology such as self-crossing rings triggers Boost.Geometry to throw an internal logic_error, which MySQL re-labels as 3043.
Coordinates outside the defined spatial reference system (for example longitude > 180 in SRID 4326) overflow internal calculations, producing the same error.
Library bugs in early 8.0.x or 5.7.x releases occasionally mis-handle perfectly valid shapes, especially with ST_Buffer and high precision.
Corrupted blobs stored in geometry columns arise from application bugs or improper binary manipulation, yielding unreadable objects that crash the parser.
First reproduce the error in isolation with a SELECT using the same spatial function. This narrows down the specific geometry row causing failure.
Validate suspect shapes using ST_IsValid or the OpenGIS function ST_IsSimple. Invalid rows return 0 or NULL, confirming corruption.
Repair invalid polygons by exporting to WKT, running an external tool like PostGIS ST_MakeValid or GDAL ogr2ogr -makevalid, and re-importing the cleaned geometry.
If coordinates exceed SRID limits, transform them with ST_SwapXY or ST_Transform into a suitable SRID or clamp values within legal bounds.
For library bugs, upgrade MySQL to the latest 8.0 LTS or apply the specific patch level noted in the release notes for spatial fixes.
Bulk load of third-party shapefiles fails - run ogr2ogr with -nlt PROMOTE_TO_MULTI and -makevalid before loading.
Real-time inserts from a GPS feed throw 3043 - implement a CHECK constraint using ST_IsValid and range checks to reject bad rows early.
Legacy polygons break after upgrading MySQL - script a pass that SELECTs id WHERE NOT ST_IsValid(geom) and rebuild those rows.
Always validate external GIS data with ST_IsValid before inserting into production tables.
Use CHECK constraints or BEFORE INSERT triggers to enforce coordinate ranges and SRID consistency.
Keep MySQL upgraded; spatial libraries receive frequent bug fixes. Pin minor versions in CI to detect regressions early.
Galaxy’s editor surfaces error 3043 immediately in the results pane and lets you share the failing query with teammates via Collections. Its AI copilot can auto-generate a validation query using ST_IsValid, accelerating the fix.
ER_GIS_INVALID_DATA (3037) indicates geometry parsing failure before Boost.Geometry is called.
ER_BOOST_GEOMETRY_EMPTY_INPUT_EXCEPTION (3044) arises when the input geometry is NULL or empty.
ER_BOOST_GEOMETRY_NOT_IMPLEMENTED (3045) appears when a spatial operation is not yet supported for the geometry type.
Polygons that cross themselves or have duplicate points violate Boost.Geometry rules and trigger 3043.
Latitude, longitude, or projected coordinates outside SRID limits overflow calculations and raise an exception.
BLOBs manipulated outside MySQL can lose endian markers or length bytes and crash the parser.
Specific MySQL patch levels include bugs where otherwise valid geometries make Boost.Geometry throw an unknown exception.
Thrown when geometry parsing fails; fix by supplying valid WKB or WKT.
Occurs when input geometry is NULL or empty; check for missing data before calling functions.
Signals the spatial operation is not supported for the given geometry type; switch to a supported function.
No. The exception occurs inside Boost.Geometry regardless of strict mode. Only fixing or preventing bad geometry solves it.
Queries will continue to fail on each invalid row. Filter or repair the geometry first.
MySQL 8.0 lacks ST_MakeValid. Use external tools like PostGIS or GDAL to repair polygons and re-import them.
Galaxy flags the exact query, lets teammates collaborate on a fix, and its AI copilot drafts validation scripts that catch bad geometry before production.
