MySQL Error 3039: Empty Geometry Centroid Calculation
Description
This error indicates that a spatial function, specifically one designed to calculate a centroid (like `ST_Centroid()`), failed because the input geometry object was empty. It commonly occurs when attempting to calculate the centroid of an uninitialized, invalid, or truly empty geometry.
Error Message
Unable to calculate centroid because geometry is empty in function %s.
Known Causes
4 known causesUninitialized or Empty Geometry
A spatial column or variable was created but contains no valid geometry data, leading to an empty input for centroid calculation.
Invalid or Malformed Geometry
Geometry data might be malformed or topologically invalid, causing it to be interpreted as empty by the centroid function, even if it appears to contain data.
Query Filtering Resulted in No Geometries
A query attempting centroid calculation on a filtered dataset returned no matching geometries, resulting in an empty set for processing.
Null Geometry Values
The geometry column or expression contains NULL values, which are treated as empty when a centroid function is invoked.
