MySQL Error 4107: Unused SRS Projection Parameter
Description
This error indicates that a Spatial Reference System (SRS) definition for a specific SRID contains one or more projection parameters that are not recognized or are redundant for the defined coordinate system. It typically occurs when creating or altering spatial tables, or when MySQL attempts to validate an existing SRS definition.
Error Message
The spatial reference system definition for SRID %u contains unused projection parameter %s.
Known Causes
4 known causesIncorrect SRS Definition
The SRID definition was manually created or modified with parameters that do not apply to the specified coordinate system or are syntactically incorrect.
Obsolete or Redundant Parameters
The SRS definition includes projection parameters that are no longer used or are superseded by other parameters within the same definition, making them redundant.
Migration Inconsistencies
Spatial data or schema migrated from another system might contain SRS definitions that are incompatible with MySQL's expected parameter set for a given SRID.
Typographical Errors
A simple typo in a projection parameter name or value within the SRS definition can cause MySQL to interpret it as an unused or unrecognized parameter.
