You can use SQL to create a view on tables and feature classes in an enterprise geodatabase.
The examples in this topic show how to create a simple view in PostgreSQL to restrict user access to specific columns. The example is based on a table with the following definition:
CREATE TABLE employees(emp_id integer not null, name varchar(32),
department smallint not null, hire_date timestamp without time zone not null
Grant privileges on the table
If the user creating the view is not the owner of the table or tables on which the view is based, the table owner must grant the view creator at least the privilege to select from the table.
In this example, the table on which the view is based (employees) is owned by the user gdb. The user creating the view is user rocket.
psql testdb gdb
Enter password for user gdb:
GRANT SELECT
ON gdb.employees
TO rocket;
Create a view
In this example, user rocket creates a view on the employees table to restrict access to only those records where the department is 201:
psql testdb rocket
Enter password for user rocket:
CREATE VIEW view_dept_201
AS SELECT emp_id, name, hire_date
FROM gdb.employees
WHERE department = 201;
Grant privileges on the view
You can grant privileges on the view to specific users without having to grant those users access to the base table (employees). In this example, the user mgr200 is granted SELECT privileges on the view, view_dept_201:
GRANT SELECT
ON rocket.view_dept_201
TO mgr200;
Test privileges
Log in as mgr200 and select records from view_dept_201:
psql testdb mgr200
Enter password for mgr200:
SELECT * FROM rocket.view_dept_201;
emp_id name hire_date

As expected, only records for employees in department 201 are returned.
