CREATE USER

Function

CREATE USER creates a user.

Important Notes

• A user created using the CREATE USER statement has the LOGIN permission by default.
• A schema named after the user is automatically created in the database where the statement is executed, but not in other databases. You can run the CREATE SCHEMA statement to create such a schema for the user in other databases.
• The owner of an object created by a system administrator in a schema with the same name as a common user is the common user, not the system administrator.
• Users other than system administrators cannot create objects in a schema named after a user, unless the users are granted with the role permissions of that schema. For details, see After the all Permission Is Granted to the Schema of a User, the Error Message "ERROR: current user does not have privilege to role tom" Persists During Table Creation in Troubleshooting.

Syntax

1

CREATE USER user_name [ [ WITH ] option [ ... ] ] [ ENCRYPTED | UNENCRYPTED ] { PASSWORD | IDENTIFIED BY } { 'password' | DISABLE };

The option clause is used for setting information including permissions and attributes.
