EXEC [ queryHint ] <multipartIdentifier>.<methodName> [ <methodArguments> ];

Query Hints​

Query hints supported for the EXEC command are summarised below:

HintDescription
/*+ SHOWRESULTS */Returns result set, designed for methods that return data, use SELECT however if possible.
/*+ AWAIT */Makes the operation blocking (synchronous), provides script control for long running operations (e.g. mutation operations).

Examples​

Stopping a Google Compute Engine instance​

Run an EXEC statement to stop a running Compute Engine instance in an authenticated session.

-- Stop a running Compute Engine resource instance
EXEC compute.instances.stop 
@instance = 'demo-instance-1', 
@project = 'stackql-demo', 
@zone = 'australia-southeast1-a';

Starting a Google Compute Engine instance (synchronous option)​

Run an EXEC statement to start a stopped Compute Engine instance in an authenticated session, uses the /*+ AWAIT */ query hint to make the operation blocking (synchronous).

-- Start a stopped Compute Engine resource instance
EXEC /*+ AWAIT  */ compute.instances.stop 
@instance = 'demo-instance-1', 
@project = 'stackql-demo', 
@zone = 'australia-southeast1-a';

Attach a Disk to a Google Compute Engine instance​

Run an EXEC statement to attach a Disk to a Compute Engine instance in an authenticated session.

-- Attach a Disk resource to a Compute Engine instance
EXEC compute.instances.attachDisk 
@zone='australia-southeast1-a', 
@project='stackql-demo', 
@instance='demo-instance-1'

}';
