MSFT_UCCommandTraceEvent class
The MSFT_UCCommandTraceEvent class is an extension of MSFT_UCTraceEventBase. By using this class, you can observe the execution of individual statements in an updating consumer. For statements associated with data queries, there is an event fired for each data object that is returned from the query. The event object that causes the execution of the updating consumer is also stored in this object. These tracing events are represented by MSFT_UCUpdateCommandTraceEvent, MSFT_UCInsertCommandTraceEvent, and MSFT_UCDeleteCommandTraceEvent.
Note For more information about support and installation of this component on a specific operating system, see Operating System Availability of WMI Components.

Members
The MSFT_UCCommandTraceEvent class has these types of members:
- Properties
Properties
The MSFT_UCCommandTraceEvent class has these properties.
CommandIndex
Data type: uint32
Access type: Read-only
Index of the statement that is being executed. This property is inherited from MSFT_UCTraceEventBase.
Consumer
Data type: MSFT_UpdatingConsumer
Access type: Read-only
Instance of MSFT_UpdatingConsumer that is being executed. This property is inherited from MSFT_UCTraceEventBase.
Data
Data type: object
Access type: Read-only
Data object that is used when executing the statement.
ErrorStr
Data type: string
Access type: Read-only
Information about an error (StatusCode greater than 1). For example, if an updating consumer contains an UPDATE statement that is not valid, the ErrorStr property contains information about the part of the query that is not valid. This property is inherited from MSFT_UCTraceEventBase.
Event
Data type: __Event
Access type: Read-only
Object that contains the event being indicated to the updating consumer instance. This property is inherited from MSFT_UCTraceEventBase.
ExecutionId
Data type: string
Access type: Read-only
Unique identifier that represents the execution of the updating consumer. Each execution of an updating consumer for an event has a unique identifier. The identifier permits correlation of the command trace events because all commands executed for an updating consumer have the same ExecutionId value. This property is inherited from MSFT_UCTraceEventBase.
SECURITY_DESCRIPTOR
Data type: uint8 array
Access type: Read-only
Descriptor that the event provider uses to determine the users that can receive the event. This property is inherited from MSFT_UCTraceEventBase.
StatusCode
Data type: uint32
Access type: Read-only
Status code that represents the outcome of a command or consumer trace event. This property is inherited from MSFT_UCTraceEventBase.
TIME_CREATED
Data type: uint64
Access type: Read-only
Unique value that indicates the time when an event is generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Time (UTC) format. This property is inherited from MSFT_UCTraceEventBase.
