What is Schema in SQL Server 2005? Explain its properties with example?
A schema is nothing more than a named, logical container in which you can create database objects. A new schema is created using the CREATE SCHEMA DDL statement.
Properties
- Ownership of schemas and schema-scoped securables is transferable.
- Objects can be moved between schemas
- A single schema can contain objects owned by multiple database users.
- Multiple database users can share a single default schema.
- Permissions on schemas and schema-contained securables can be managed with greater precision than in earlier releases.
- A schema can be owned by any database principal. This includes roles and application roles.
- A database user can be dropped without dropping objects in a corresponding schema.
