If you want to create a new schema in an existing database, you can use the "CREATE SCHEMA" statement as shown in the tutorial example below:

USE GlobalGuideLineDatabase;

GO

CREATE SCHEMA ggl;

GO

Command(s) completed successfully.

A new schema called "ggl" has been created in "GlobalGuideLineDatabase" database. "ggl" is an empty schema at this moment since no objects has been moved into "ggl" yet.
