CREATE TABLE geom (g GEOMETRY); SPATIAL indexes can be created on NOT NULL spatial columns, so if you plan to index the column, declare it NOT NULL: CREATE TABLE geom (g GEOMETRY NOT NULL); For other examples showing how to use spatial data types in MySQL, see Section 11.4.5, “Creating Spatial Columns”.
