  • Artikkeli

Applies to: Azure Synapse Analytics Analytics Platform System (PDW)

sp_pdw_add_network_credentials stores network credentials in Azure Synapse Analytics and associates them with a server. For example, use this stored procedure to give Azure Synapse Analytics appropriate read/write permissions to perform database backup and restore operations on a target server, or to create a backup of a certificate used for transparent data encryption (TDE).

Transact-SQL syntax conventions

Syntax

Syntax for Azure Synapse Analytics and Analytics Platform System (PDW).

sp_pdw_add_network_credentials
    'target_server_name'
    , 'user_name'
    , 'password'
[ ; ]

Note

This syntax is not supported by serverless SQL pool in Azure Synapse Analytics.

Arguments

'target_server_name'

Specifies the target server host name or IP address. target_server_name is nvarchar(337) with no default. Azure Synapse Analytics accesses this server with the username and password credentials passed to this stored procedure.

To connect through the InfiniBand network, use the InfiniBand IP address of the target server.

'user_name'

Specifies the user_name that's permissions to access the target server. user_name is nvarchar(513) with no default. If credentials already exist for the target server, they're updated to the new credentials.

'passwordꞌ

Specifies the password for user_name.

Return code values

0 (success) or 1 (failure).

Permissions

Requires ALTER SERVER STATE permission.

Error Handling

An error occurs if adding credentials doesn't succeed on the Control node and all Compute nodes.

Remarks

This stored procedure adds network credentials to the NetworkService account for Azure Synapse Analytics. The NetworkService account runs each instance of SMP SQL Server on the Control node and the Compute nodes. For example, when a backup operation runs, the Control node and each Compute node use the NetworkService account credentials to gain read and write permission to the target server.

Examples: Azure Synapse Analytics and Analytics Platform System (PDW)

A. Add credentials for performing a database backup

The following example associates the user name and password credentials for the domain user seattle\david with a target server that's an IP address of 10.172.63.255. The user seattle\david has read/write permissions to the target server. Azure Synapse Analytics stores these credentials and uses them to read and write to and from the target server, as necessary for backup and restore operations.

EXEC sp_pdw_add_network_credentials
    '10.172.63.255',
    'seattle\david',
    '********';

The backup command requires that the server name is entered as an IP address.

Note

To perform the database backup over InfiniBand, be sure to use the InfiniBand IP address of the backup server.
