Update a firewall rule for an Azure SQL Database server.

Important

The recommended REST commands to work with SQL Database are the Resource Manager based Azure SQL Database REST API. While there is no change to SQL Database, be aware that the classic deployment model command in this article is scheduled for deprecation on December 1, 2019. For a table providing links to the specific new commands you should use, see Operations for Azure SQL Databases.

Request

The Set Firewall Rule request must be specified as follows:

Replace {subscriptionId} with your subscription ID.
Replace {serverName} with the name of the server to set the firewall rule on.
Replace {firewallRuleName} with your firewall rule name.

Method	Request URI	HTTP Version
PUT	https://management.core.windows.net:8443/{subscriptionId}/services/sqlservers/servers/{serverName}/firewallrules/{firewallRuleName}	HTTP/1.1

If the operation returns success, the operation is complete, but changes will be effective five minutes later. If the operation returns failure, and the error is user error, no changes will be applied. If there is a communication error or an internal server error, the current state needs to be determined with Get Firewall Rule (classic).

In SQL Database, login data required to authenticate a connection and server-level firewall rules are temporarily cached in each database. This cache is periodically refreshed. To force a refresh of the authentication cache and make sure that a database has the latest version of the logins table, execute DBCC FLUSHAUTHCACHE (Transact-SQL).

URI Parameters

None.

Request Headers

The following table describes the required and optional request headers:

Request Header	Description
