Creating a spatial column (SQL)

Add spatial data to any table by adding a column that supports spatial data.

Prerequisites

You must be the owner of the table, or have ALTER privilege on the table, or have the ALTER ANY TABLE or ALTER ANY OBJECT system privilege.

Procedure

Connect to the database.
Execute an ALTER TABLE statement.

Results

A spatial column is added to the existing table.

Example

The following statement adds a spatial column named Location to the Customers table. The new column is of spatial data type ST_Point, and has a declared SRID of 1000004326, which is a flat-Earth spatial reference system.

ALTER TABLE GROUPO.Customers
ADD Location ST_Point(SRID=1000004326);

Next Steps

You can place SRID constraints on the column to place restrictions on the values that can be stored in a spatial column.
