How to assign permissions by schema in SQL Server

To assign permissions to a schema in SQL Server, you must first create a security role and assign permissions to the role. Then, assign the role to the desired user or group of users. Here is an example of code to assign SELECT permissions to a «test_schema» schema:

sqlCopy code-- Create a security role
CREATE ROLE test_role;

-- Grant SELECT permission on the schema to the role
GRANT SELECT ON SCHEMA::test_schema TO test_role;

-- Assign the role to a user
EXEC sp_addrolemember 'test_role', 'user_name';

Replace «user_name» with the name of the user or group of users you want to assign permissions to.
