This guide will walk you through the process of creating users in Snowflake, including the necessary syntax, parameters, and best practices to ensure security and efficiency. Whether you are new to Snowflake or looking to refine your user management skills, this tutorial will provide you with the knowledge you need.
Creating a user in Snowflake involves using the CREATE USER command, which allows administrators to define user accounts with specific properties and parameters. This command can be executed by users with the appropriate privileges, such as user administrators. Understanding the syntax and options available is essential for configuring user accounts to meet organizational requirements.
CREATE [ OR REPLACE ] USER [ IF NOT EXISTS ] <name>
[ objectProperties ]
[ objectParams ]
[ sessionParams ]
[ [ WITH ] TAG ( <tag_name> = ' <tag_value> ' [ , <tag_name> = ' <tag_value> ' , ... ] ) ]
This syntax provides flexibility in user creation, allowing for various configurations through optional properties and parameters. Below, we break down each component of the command:
The only required parameter for creating a user in Snowflake is the name. This unique identifier must start with an alphabetic character and cannot contain spaces or special characters unless enclosed in double quotes. The name ensures that each user account is distinct within the Snowflake environment.
Optional object properties allow for additional customization of the user account. These properties include:
Optional object parameters control specific settings for the user. These parameters include:
Session parameters control various aspects of the user's session behavior. Some of these parameters include:
For a complete list of session parameters, refer to the Snowflake documentation.
CREATE USER john_doe
PASSWORD = 'StrongPassword123'
LOGIN_NAME = 'john_doe'
EMAIL = 'john.doe@example.com'
DISPLAY_NAME = 'John Doe';
This example demonstrates the creation of a basic user with essential properties such as password, login name, email, and display name.
CREATE USER jane_doe
PASSWORD = 'AnotherStrongPassword456'
LOGIN_NAME = 'jane_doe'
EMAIL = 'jane.doe@example.com'
DISPLAY_NAME = 'Jane Doe'
FIRST_NAME = 'Jane'
LAST_NAME = 'Doe'
MUST_CHANGE_PASSWORD = TRUE
DISABLED = FALSE
DEFAULT_WAREHOUSE = 'compute_wh'
DEFAULT_NAMESPACE = 'database.schema';
This example includes additional properties such as the user's first and last names, a requirement to change the password on the next login, and default settings for the warehouse and namespace.
CREATE USER mike_smith
PASSWORD = 'YetAnotherStrongPassword789'
LOGIN_NAME = 'mike_smith'
EMAIL = 'mike.smith@example.com'
DISPLAY_NAME = 'Mike Smith'
FIRST_NAME = 'Mike'
LAST_NAME = 'Smith'
ENABLE_UNREDACTED_QUERY_SYNTAX_ERROR = TRUE
NETWORK_POLICY = 'corp_network_policy'
SESSION TIMEZONE = 'America/Los_Angeles'
AUTOCOMMIT = TRUE;
This example demonstrates the creation of a user with both object and session parameters, providing a comprehensive configuration for the user account.
When creating users in Snowflake, it is essential to follow best practices to ensure security, efficiency, and maintainability.
DAYS_TO_EXPIRY parameter to enforce regular password changes.DISABLED parameter to disable accounts that are no longer in use.DEFAULT_WAREHOUSE and DEFAULT_NAMESPACE to streamline user sessions.The first step in creating a user is to define the user name, which must be unique within the Snowflake account. This name serves as the primary identifier for the user.
CREATE USER john_doe;
This command creates a user with the name john_doe. At this stage, no additional properties or parameters are set.
Next, set a password and login name for the user. These properties are essential for user authentication and access.
CREATE USER john_doe
PASSWORD = 'StrongPassword123'
LOGIN_NAME = 'john_doe';
This command sets a strong password and a login name for the user. The login name can be the same as the user name or different, depending on your preference.
To enhance the user account, add optional properties such as email, display name, and default settings.
CREATE USER john_doe
PASSWORD = 'StrongPassword123'
LOGIN_NAME = 'john_doe'
EMAIL = 'john.doe@example.com'
DISPLAY_NAME = 'John Doe'
DEFAULT_WAREHOUSE = 'compute_wh'
DEFAULT_NAMESPACE = 'database.schema';
This command includes additional properties to provide a more comprehensive configuration for the user account.
For advanced user management, configure object and session parameters to control specific settings and behaviors.
CREATE USER john_doe
PASSWORD = 'StrongPassword123'
LOGIN_NAME = 'john_doe'
EMAIL = 'john.doe@example.com'
DISPLAY_NAME = 'John Doe'
ENABLE_UNREDACTED_QUERY_SYNTAX_ERROR = TRUE
NETWORK_POLICY = 'corp_network_policy'
SESSION TIMEZONE = 'America/Los_Angeles'
AUTOCOMMIT = TRUE;
This command demonstrates the inclusion of both object and session parameters, providing a detailed configuration for the user account.
While creating users in Snowflake, administrators may encounter common challenges or errors. Here are some solutions to address these issues:
IF NOT EXISTS clause to avoid conflicts.MUST_CHANGE_PASSWORD parameter to require users to set a new password upon first login.Creating users in Snowflake is a straightforward yet highly customizable process. Key takeaways from this tutorial include:
By applying these principles, administrators can ensure that user accounts are configured correctly, securely, and efficiently, contributing to the overall success of their Snowflake implementation.
