# Create a Database Schema
  This topic describes how to create a schema in [!INCLUDE[ssCurrent](../../../includes/sscurrent-md.md)] by using [!INCLUDE[ssManStudioFull](../../../includes/ssmanstudiofull-md.md)] or [!INCLUDE[tsql](../../../includes/tsql-md.md)].

     [Limitations and Restrictions](#Restrictions)  
  
     [Security](#Security)  
  
-   **To create a schema, using:**  
  
     [SQL Server Management Studio](#SSMSProcedure)  
  
     [Transact-SQL](#TsqlProcedure)  
  
##  <a name="BeforeYouBegin"></a> Before You Begin  
  
###  <a name="Restrictions"></a> Limitations and Restrictions  
  
-   The new schema is owned by one of the following database-level principals: database user, database role, or application role. Objects created within a schema are owned by the owner of the schema, and have a NULL **principal_id** in **sys.objects**. Ownership of schema-contained objects can be transferred to any database-level principal, but the schema owner always retains CONTROL permission on objects within the schema.  
  
-   When creating a database object, if you specify a valid domain principal (user or group) as the object owner, the domain principal is added to the database as a schema. The new schema is owned by that domain principal.  
  
###  <a name="Security"></a> Security  
  
####  <a name="Permissions"></a> Permissions  
  
-   Requires CREATE SCHEMA permission on the database.  
  
-   To specify another user as the owner of the schema being created, the caller must have IMPERSONATE permission on that user. If a database role is specified as the owner, the caller must meet one of the following criteria: membership in the role or ALTER permission on the role.  
  
##  <a name="SSMSProcedure"></a> Using SQL Server Management Studio  
  
##### To create a schema  
  
1.  In Object Explorer, expand the **Databases** folder.  
  
2.  Expand the database in which to create the new database schema.  
  
3.  Right-click the **Security** folder, point to **New**, and select **Schema**.  
  
4.  In the **Schema - New** dialog box, on the **General** page, enter a name for the new schema in the **Schema name** box.  
  
5.  In the **Schema owner** box, enter the name of a database user or role to own the schema. Alternately, click **Search** to open the **Search Roles and Users** dialog box.  
  
6.  [!INCLUDE[clickOK](../../../includes/clickok-md.md)]  
  
### Additional Options  
 The **Schema– New** dialog box also offers options on two additional pages: **Permissions** and **Extended Properties**.  
  
-   The **Permissions** page lists all possible securables and the permissions on those securables that can be granted to the login.  
  
-   The **Extended properties** page allows you to add custom properties to database users.  
  
##  <a name="TsqlProcedure"></a> Using Transact-SQL  
  
#### To create a schema  
  
1.  In **Object Explorer**, connect to an instance of [!INCLUDE[ssDE](../../../includes/ssde-md.md)].  
  
2.  On the Standard bar, click **New Query**.  
  
3.  The following example creates a schema named `Chains`, and then creates a table named `Sizes`.  
    ```sql  
    CREATE SCHEMA Chains;
    GO
    CREATE TABLE Chains.Sizes (ChainID int, width dec(10,2));
    ```

4.  Additional options can be performed in a single statement. The following example creates the schema `Sprockets` owned by Annik that contains table `NineProngs`. The statement grants `SELECT` to Mandar and denies `SELECT` to Prasanna.  

    ```sql  
    CREATE SCHEMA Sprockets AUTHORIZATION Annik  
        CREATE TABLE NineProngs (source int, cost int, partnumber int)  
        GRANT SELECT ON SCHEMA::Sprockets TO Mandar  
        DENY SELECT ON SCHEMA::Sprockets TO Prasanna;  
    GO  
    ```  
5. Execute the following statement, to view the schemas in this database:

   ```sql
   SELECT * FROM sys.schemas;
   ```
