CREATE USER
Function
The CREATE USER statement establishes a user as a prerequisite to having access.
Syntax
CREATE USER user_identifier [PASSWORD password] [SCHEMA [schema_identifier]]
where

user_identifier | A unique identifier for a user.
password | A valid password string with a maximum length of 20 bytes.
schema_identifier | A valid default schema identifier.

Description
CREATE USER defines a user with an optional password and optional character set. If a password has been specified, the user must enter it to gain access to the system. If no password has been specified, this user will have no password protection.
The SCHEMA option has an effect on the setting of the default schema after the user's CONNECT. The default is equal to the user identifier. If the schema does not already exist, it is created implicitly with the specified user as owner.
The CHARACTER SET option defines a default character set which is used when the user connects to the server without specifying a character set explicitly. The default is 'US-ASCII'.
All settings specified here can be changed later using the ALTER USER statement.
Note:
The provided password is visible in this statement. After the execution of the statement, the password is encrypted internally.
Limitations
In order to create users, you must be a database administrator. Database administrators are identified in the CONNX CDD as members of the group CONNXCDDAdministrators.
The user identifier must be unique.
Warning:
This statement is not subject to transaction logic. An implicit COMMIT will be performed after successful execution of this statement. If an error is detected during execution of this statement, an implicit ROLLBACK will be performed. Therefore, before executing this statement, it is strongly recommended to complete any open transaction containing INSERT, UPDATE and/or DELETE statements by issuing an explicit COMMIT or ROLLBACK statement.
ANSI Specifics
The CREATE USER statement is not part of the Standard.
Examples
The following example defines the user TIM with a password and a schema.
CREATE USER 'TIM' PASSWORD '&M%I?T' SCHEMA 'TIM';
