ALTER CONNECTION¶

Syntax¶

ALTER CONNECTION [ IF EXISTS ] <name> ENABLE FAILOVER TO ACCOUNTS <organization_name>.<account_name> [ , <organization_name>.<account_name> ... ]
                        [ IGNORE EDITION CHECK ]

ALTER CONNECTION [ IF EXISTS ] <name> DISABLE FAILOVER [ TO ACCOUNTS <organization_name>.<account_name> [ , <organization_name>.<account_name> ... ] ]

ALTER CONNECTION [ IF EXISTS ] <name> PRIMARY

ALTER CONNECTION [ IF EXISTS ] <name> SET COMMENT = '<string_literal>'

ALTER CONNECTION [ IF EXISTS ] <name> UNSET COMMENT

Parameters¶

name

Identifier for the connection to alter.

ENABLE FAILOVER TO ACCOUNTS organization_name.account_name [ , organization_name.account_name ... ]

Specifies a comma-separated list of accounts in your organization where a secondary connection for this primary connection can be promoted to serve as the primary connection. Include your organization name for each account in the list.

Each account in the list must be located in a different region than the account with the primary connection. Otherwise, the command fails.

DISABLE FAILOVER [ TO ACCOUNTS organization_name.account_name [ , organization_name.account_name ... ] ]

Disables failover for this primary connection, meaning no secondary connection for this primary connection can be promoted to serve as the primary connection.

To disable failover to selected accounts (rather than to all accounts), specify a comma-delimited list of those accounts.

PRIMARY

Promote connection to serve as primary connection.

SET ...

Specifies the properties to set for the connection:

COMMENT = 'string'

Adds a comment or overwrites an existing comment for the connection.

UNSET ...

Specifies the properties to unset for the connection, which resets them to the defaults.

Currently, the only property you can unset is COMMENT, which removes the comment, if one exists, for the connection.

Usage notes¶

• Only account administrators (users with the ACCOUNTADMIN role) can execute this SQL command.

• If private connectivity to the Snowflake service is enabled for your Snowflake account, your network administrator must update the DNS CNAME record for your connection URL when a connection is promoted to serve as the primary connection. For more information, see Configuring the DNS settings for private connectivity to the Snowflake service.

• Regarding metadata:

  Attention

  Customers should ensure that no personal data (other than for a User object), sensitive data, export-controlled data, or other regulated data is entered as metadata when using the Snowflake service. For more information, see Metadata fields in Snowflake.

Examples¶

Allow accounts myaccount2 and myaccount3 in the myorg organization to each store a secondary connection for the myconnection connection:

ALTER CONNECTION myconnection ENABLE FAILOVER TO ACCOUNTS myorg.myaccount2, myorg.myaccount3;

Add a comment for a connection:

ALTER CONNECTION myconnection SET COMMENT = 'New comment for connection';

Promote a secondary connection to primary connection:

ALTER CONNECTION myconnection PRIMARY;
