정의

SqlTrackingQueryOptions 클래스의 새 인스턴스를 초기화합니다.

public:
 SqlTrackingQueryOptions();
public SqlTrackingQueryOptions ();
Public Sub New ()

예제

다음 예제에서는 SqlTrackingQueryOptions 클래스의 인스턴스를 만드는 방법을 보여 줍니다. 이 예제는 Workflow Monitor SDK 샘플에 포함되어 있습니다. 자세한 내용은 Workflow Monitor 샘플합니다.

try
{
    List<SqlTrackingWorkflowInstance> queriedWorkflows = new List<SqlTrackingWorkflowInstance>();
    SqlTrackingQuery sqlTrackingQuery = new SqlTrackingQuery(connectionString);
    SqlTrackingQueryOptions sqlTrackingQueryOptions = new SqlTrackingQueryOptions();
    sqlTrackingQueryOptions.StatusMinDateTime = from.ToUniversalTime();
    sqlTrackingQueryOptions.StatusMaxDateTime = until.ToUniversalTime();
    // If QualifiedName, FieldName, or DataValue is not supplied, we will not query since they are all required to match
    if (!((string.Empty == trackingDataItemValue.QualifiedName) || (string.Empty == trackingDataItemValue.FieldName) || ((string.Empty == trackingDataItemValue.DataValue))))
        sqlTrackingQueryOptions.TrackingDataItems.Add(trackingDataItemValue);

    queriedWorkflows.Clear();

    if ("created" == workflowEvent.ToLower(CultureInfo.InvariantCulture))
    {
        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Created;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));
    }
    else if ("completed" == workflowEvent.ToLower(CultureInfo.InvariantCulture))
    {
        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Completed;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));
    }
    else if ("running" == workflowEvent.ToLower(CultureInfo.InvariantCulture))
    {
        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Running;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));
    }
    else if ("suspended" == workflowEvent.ToLower(CultureInfo.InvariantCulture))
    {
        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Suspended;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));
    }
    else if ("terminated" == workflowEvent.ToLower(CultureInfo.InvariantCulture))
    {
        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Terminated;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));
    }
    else if (("all" == workflowEvent.ToLower(CultureInfo.InvariantCulture)) || string.IsNullOrEmpty(workflowEvent))
    {
        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Created;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));

        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Completed;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));

        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Running;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));

        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Suspended;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));

        sqlTrackingQueryOptions.WorkflowStatus = WorkflowStatus.Terminated;
        queriedWorkflows.AddRange(sqlTrackingQuery.GetWorkflows(sqlTrackingQueryOptions));
    }
    return queriedWorkflows;
}
catch (Exception exception)
{
    throw new Exception("Exception in GetWorkflows", exception);
}

설명

다음 표에서는 SqlTrackingQueryOptions 클래스의 인스턴스에 대한 초기 속성 값을 보여 줍니다.

속성
StatusMaxDateTime MaxValue.
StatusMinDateTime MinValue.
TrackingDataItems List<T>입니다.
WorkflowStatus null 참조(Visual Basic의 경우 Nothing)
WorkflowType null 참조(Visual Basic의 경우 Nothing)

이 값은 SqlTrackingQuery.GetWorkflows 호출에서 데이터베이스에 추적 데이터가 있는 모든 워크플로 인스턴스에 대해 SqlTrackingWorkflowInstance 개체를 반환하도록 지정합니다.
