MariaDB Error 1252: Spatial Index Requires NOT NULL
Description
This error occurs when you attempt to create or modify a table to include a `SPATIAL` index, but one or more of the columns participating in that index are defined to allow `NULL` values. MariaDB's `SPATIAL` indexes have a strict requirement that all indexed columns must be explicitly marked as `NOT NULL`.
Error Message
All parts of a SPATIAL index must be NOT NULL
Known Causes
3 known causesNullable Column Definition
The `CREATE TABLE` or `ALTER TABLE` statement attempts to define a `SPATIAL` index on a column that is specified as `NULLABLE` (i.e., it doesn't have the `NOT NULL` constraint).
Missing NOT NULL Constraint
When designing your table schema, the `NOT NULL` constraint was inadvertently omitted from the definition of a column intended for a `SPATIAL` index.
Existing NULL Data
You are attempting to add a `SPATIAL` index to an existing table, and the target column(s), even if later altered to `NOT NULL`, still contain `NULL` values from previous insertions.
