sp_set_database_firewall_rule (Azure SQL Database)
Applies to: Azure SQL Database
Creates or updates the database-level firewall rules for your Azure SQL Database. Database firewall rules can be configured for the master
database, and for user databases on SQL Database. Database firewall rules can be useful when using contained database users. For more information, see Make your database portable by using contained databases.
sp_set_database_firewall_rule
[ @name = ] N'name'
, [ @start_ip_address = ] 'start_ip_address'
, [ @end_ip_address = ] 'end_ip_address'
[ ; ]
The name used to describe and distinguish the database-level firewall setting. @name is nvarchar(128) with no default.
The lowest IP address in the range of the database-level firewall setting. IP addresses equal to or greater than this value can attempt to connect to the SQL Database instance. The lowest possible IP address is 0.0.0.0
. @start_ip_address is varchar(50) with no default.
The highest IP address in the range of the database-level firewall setting. IP addresses equal to or less than this value can attempt to connect to the SQL Database instance. The highest possible IP address is 255.255.255.255
. @end_ip_address is varchar(50) with no default.
The following table demonstrates the supported arguments and options in SQL Database.
Note
Azure connection attempts are allowed when both this field and the @start_ip_address field equals 0.0.0.0
.
The names of database-level firewall settings for a database must be unique. If the name of the database-level firewall setting provided for the stored procedure already exists in the database-level firewall settings table, the starting and ending IP addresses are updated. Otherwise, a new database-level firewall setting is created.
When you add a database-level firewall setting where the beginning and ending IP addresses are equal to 0.0.0.0
, you enable access to your database in the SQL Database server from any Azure resource. Provide a value to the @name parameter that helps you remember what the firewall setting is for.
Requires CONTROL
permission on the database.
The following code creates a database-level firewall setting called Allow Azure
that enables access to your database from Azure.
EXECUTE sp_set_database_firewall_rule N'Allow Azure', '0.0.0.0', '0.0.0.0';
The following code creates a database-level firewall setting called Example DB Setting 1
for only the IP address 0.0.0.4
. Then, the sp_set_database firewall_rule
stored procedure is called again to update the end IP address to 0.0.0.6
, in that firewall setting. This example creates a range that allows IP addresses 0.0.0.4
, 0.0.0.5
, and 0.0.0.6
to access the database.
Create database-level firewall setting for only IP 0.0.0.4:
EXECUTE sp_set_database_firewall_rule N'Example DB Setting 1', '0.0.0.4', '0.0.0.4';
Update database-level firewall setting to create a range of allowed IP addresses:
EXECUTE sp_set_database_firewall_rule N'Example DB Setting 1', '0.0.0.4', '0.0.0.6';
