CREATE SCHEMA
 AUTHORIZATION userid
[  create-table-statement
   | create-view-statement
   | grant-statement  
]  ... ;

The CREATE SCHEMA statement creates a schema. A schema is a collection of tables and views along with their associated permissions.

The userid must be the user ID of the current connection. You cannot create a schema for another user.

If any statement contained in the CREATE SCHEMA statement fails, the entire CREATE SCHEMA statement is rolled back.

The CREATE SCHEMA statement is a way of collecting together individual CREATE and GRANT statements into one operation. There is no SCHEMA database object created in the database, and to drop the objects you must use individual DROP TABLE or DROP VIEW statements. To revoke permissions, you must use a REVOKE statement for each permission granted.

The individual CREATE or GRANT statements are not separated by statement delimiters. The statement delimiter marks the end of the CREATE SCHEMA statement itself.

The individual CREATE or GRANT statements must be ordered such that the objects are created before permissions are granted on them.

Although you can create more than one schema for a user, doing so is not recommended.

Must have RESOURCE authority.

• CREATE TABLE statement
• CREATE VIEW statement
• GRANT statement

The following CREATE SCHEMA statement creates a schema consisting of two tables. The statement must be executed by the user ID sample_user, who must have RESOURCE authority. If the statement creating table t2 fails, neither table is created.

CREATE SCHEMA AUTHORIZATION sample_user
CREATE TABLE t1 ( id1 INT PRIMARY KEY )
CREATE TABLE t2 ( id2 INT PRIMARY KEY );

The statement delimiter in the following CREATE SCHEMA statement is placed after the first CREATE TABLE statement. As the statement delimiter marks the end of the CREATE SCHEMA statement, the example is interpreted as a two statement batch by the database server. If the statement creating table t2 fails, the table t1 is still created.

CREATE SCHEMA AUTHORIZATION sample_user
CREATE TABLE t1 ( id1 INT PRIMARY KEY );
CREATE TABLE t2 ( id2 INT PRIMARY KEY );
