There is a command group 'az_dt_twin'. This group of commands could 'manage and configure the digital twins of a digital twins instance'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_dt_twin_query'.The syntax is: az dt twin query --dt-name
                 --query-command
                 [--cost {false, true}]
                 [--resource-group]. The 1th example of the child command would be to use it to 'query all digital twins in target instance and project all attributes  also show cost in query units', the syntax is: az dt twin query -n {instance_or_hostname} -q "select * from digitaltwins" --show-cost. The 2th example of the child command would be to use it to 'query by model and project all attributes', the syntax is: az dt twin query -n {instance_or_hostname} -q "select * from digitaltwins T where IS_OF_MODEL(T, 'dtmi:com:example:Room;2')". The 3th example of the child command would be to use it to 'query leveraging   dtid  with bash compatible syntax', the syntax is: az dt twin query -n {instance_or_hostname} --query-command "SELECT * FROM DigitalTwins T Where T.\$dtId = 'room0'". The 4th example of the child command would be to use it to 'query leveraging   dtid  with powershell compatible syntax', the syntax is: az dt twin query -n {instance_or_hostname} --query-command "SELECT * FROM DigitalTwins T Where T.`$dtId = 'room0'". The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name or hostname. if an instance name is provided, the user subscription is first queried for the target instance to retrieve the hostname. if a hostname is provided, the subscription query is skipped and the provided value is used for subsequent interaction.. The parameter '--query-command -q' is required. It is used to user query to be executed.. The parameter '--cost --show-cost' is optional. calculates and shows the query charge.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`..
