MySQL Error 3516: Unexpected Geometry Type in Queries
Description
MySQL Error 3516 indicates that a spatial value provided in a query or operation is of a geometry type that is not expected or compatible with the context it's being used in. This typically occurs when working with spatial data (GIS) functions or columns, where there's a mismatch between the actual geometry type (e.g., a POINT) and the type that MySQL expects (e.g., a LINESTRING) for a specific operation or column definition.
Error Message
%s value is a geometry of unexpected type %s in %s.
Known Causes
3 known causesMismatched Spatial Data Format
Providing spatial data in a format (e.g., Well-Known Text or Well-Known Binary) that does not conform to the geometry type expected by the target column or spatial function.
Invalid Geometry Type for Function
Using a spatial function with a geometry type (e.g., a MULTIPOINT) when the function specifically expects a different, incompatible type (e.g., a LINESTRING or POLYGON) for its arguments.
Geometry Column Type Mismatch
Attempting to insert or update a geometry value into a spatial column that is defined for a different, incompatible geometry type (e.g., inserting a POLYGON into a POINT column).
