Creating a spatial column (SQL Central)

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.

The table must have a primary key. Update and delete operations are not supported for tables that contain a spatial column unless a primary key is defined.

Procedure

Connect to the database.
Create a new column:
- In the left pane, expand the Tables list.
- Right-click a table, then click New Column .
Set the spatial data type:
1. Right-click the column name, then click Properties.
2. Click the Data Type tab.
3. Select Built-in type and choose a spatial data type from the dropdown list.
4. Select Set spatial reference system and choose a spatial reference system from the dropdown list.
5. Click OK.
Click File Save .

Results

A spatial column is added to the existing table.

Next Steps

You can place SRID constraints on the column to place restrictions on the values that can be stored in a spatial column by using the ALTER TABLE statement. You can also add spatial data to the column.
