az dt twin query

Query the digital twins of an instance. Allows traversing relationships and filtering by property values.

In many twin queries, the $ character is used to reference the $dtId property of a twin. In bash-like shells or powershell the $ character has functional meaning and must be escaped as part of the query input. Please review the Digital Twins CLI concepts document https://docs.microsoft.com/en-us/azure/digital-twins/concepts-cli for more information.

az dt twin query --dt-name
                 --query-command

                 [--resource-group]

Examples

Query all digital twins in target instance and project all attributes. Also show cost in query units.

az dt twin query -n {instance_or_hostname} -q "select * from digitaltwins" --show-cost

Query by model and project all attributes.

az dt twin query -n {instance_or_hostname} -q "select * from digitaltwins T where IS_OF_MODEL(T, 'dtmi:com:example:Room;2')"
