The following example displays the result of the SVV\$1RLS\$1POLICY.

```
-- Create some policies.
CREATE RLS POLICY pol1 WITH (a int) AS t USING ( t.a IS NOT NULL );
CREATE RLS POLICY pol2 WITH (c varchar(10)) AS t USING ( c LIKE '%public%');

-- Inspect the policy in SVV_RLS_POLICY
SELECT * FROM svv_rls_policy;
