You can use SQL to create a view and include the spatial column in the view definition. You would do this so you can view the features in ArcMap. You might also create a spatial view to allow you to use a table that contains more than one spatial column; your spatial view would only include one spatial column so you can use it with ArcGIS.
In this example, a spatial view is created to join data from the employees table and the region feature class.
Create a view with a spatial column
Define the view to include the spatial column and ObjectID from the feature class along with the other attribute columns you want in the view.
The owner of the employees table and region feature class is the gdb user; therefore, the user already has the necessary privileges to create the view.
psql testdb gdb
Enter password for user gdb:
CREATE VIEW emp_region_view
AS SELECT (
FROM employees, hbear.regions
WHERE employees.emp_id = hbear.regions.emp_id;
The reg_id is the not null, integer ObjectID column from the region feature class. Region is the spatial column from the region feature class. The tables are joined based on the emp_id column.
Grant privileges on the spatial view
Now that the view exists, grant select privileges to dispatch_mgr.
