MySQL Error 1252: SPATIAL Index NULL Constraint
Description
This error indicates an attempt to create or modify a SPATIAL index on a table where one or more columns intended for the index are defined to permit NULL values. MySQL requires all columns participating in a SPATIAL index to explicitly be declared as NOT NULL to ensure data integrity and efficient indexing of spatial data.
Error Message
All parts of a SPATIAL index must be NOT NULL
Known Causes
3 known causesColumn defined as NULLable
Attempting to create a SPATIAL index on a column that was originally defined without the NOT NULL constraint during table creation or modification.
ALTER TABLE to add SPATIAL index
Executing an ALTER TABLE statement to add a SPATIAL index to an existing column that allows NULLs, rather than first modifying the column's NULL constraint.
Incorrect table schema design
Designing a table with spatial data types that permits NULL values in columns intended for spatial indexing, violating MySQL's requirements.
