示例

基本 UPDATE 语句

运行 UPDATE 语句，修改 Compute Engine Disk 资源的大小。

-- Update the size of a Compute Engine Disk resource
UPDATE google.compute.disks 
SET sizeGb = 20
WHERE project = 'stackql-demo' 
AND zone = 'australia-southeast1-a' 
AND name = 'test10gbdisk';

UPDATE 语句（阻塞）

运行 UPDATE 语句，修改 Compute Engine Disk 资源的大小。这是一次阻塞（同步）调用。

-- Synchronous update of a google firewall 
UPDATE /*+ AWAIT */ google.compute.firewalls
SET
 data__network = 'https://www.googleapis.com/compute/v1/projects/stackql-demo/global/networks/my-vpc',
 data__direction = 'INGRESS',
 data__sourceRanges = '["0.0.0.0/0"]',
 data__allowed = '[{"IPProtocol": "tcp", "ports": ["22"]}, {"IPProtocol": "tcp", "ports": ["6443"]},{"IPProtocol": "icmp"}]'
WHERE firewall = 'test-fw'
AND project = 'stackql-demo' 

修改 JSON 的 UPDATE 语句

运行 UPDATE 语句，通过 JSON 操作修改资源。

-- Update an Azure Network Interface's properties
UPDATE azure.network.network_interfaces
SET data__properties = json_replace(
  json_remove(data__properties,
    '$.auxiliarySku',
    '$.provisioningState',
    '$.resourceGuid',
    '$.macAddress'
  ),
  '$.ipConfigurations[0].name',
  'newIpConfigurationName'
)
WHERE subscription_id = '0123456789'
AND resource_group_name = 'vmss-flex'
AND network_interface_name = 'vmss-nic-01';
