# REPLACE

> REPLACE in StackQL: replace every field of a resource instance, equivalent to an HTTP PUT, as opposed to the partial update performed by UPDATE.

Source: https://stackql.io/language-spec/replace

Updates all fields in a resource (synonymous with a `put` operation).

## Examples

### Basic `REPLACE` statement
Run an `REPLACE` statement to modify a Compute Engine Disk resource's size.

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

### `REPLACE` statement (blocking)
Run an `REPLACE` statement to modify a Compute Engine Disk resource's size. This is a blocking (synchronous) invocation.

```sql
-- Synchronous update of a google firewall 
REPLACE /*+ 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' 
```

### `REPLACE` statement with JSON modification
Run an `REPLACE` statement to modify a resource using JSON manipulation.

```sql
-- Update an Azure Network Interface's properties
REPLACE 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';
```
