Example

The following statement uses LINQ query syntax to retrieve Task entity data from the OData interface of the Project Server reporting tables. To use the statement in an application, set a service reference to the ProjectDataService, and initialize the ReportingData context. The Tasks entity set can then be accessed as context.Tasks. For more information, see Querying OData feeds for Project 2013 reporting data.

var query =
    from t in Tasks
    where (t.TaskIndex > 0)
    orderby t.ProjectName, t.TaskIndex
    select new
    {
        Project = t.ProjectName,
        Task = t.TaskName,
        TaskWork = t.TaskWork,
        TaskCost = t.TaskCost,
        TaskDuration = t.TaskDuration,
        TaskDurationVariance = t.TaskDurationVariance,
        TaskCostVariance = t.TaskCostVariance
    };

The preceding statement can be written by using Lambda expression syntax, as follows:

var query = Tasks
    .Where(t => (t.TaskIndex > (Int32)0))
    .OrderBy(t => t.ProjectName)
    .ThenBy(t => t.TaskIndex)
    .Select(t => new
    {
        Project = t.ProjectName,
        Task = t.TaskName,
        TaskWork = t.TaskWork,
        TaskCost = t.TaskCost,
        TaskDuration = t.TaskDuration,
        TaskDurationVariance = t.TaskDurationVariance,
        TaskCostVariance = t.TaskCostVariance
    });

Either statement creates the following REST URL (all on one line).

https://ServerName/pwa/_vti_bin/client.svc/ProjectServerData/Tasks()?
     $filter=TaskIndex gt 0&
     $orderby=ProjectName,TaskIndex&$select=ProjectName,TaskName,TaskWork,
     TaskCost,TaskDuration,TaskDurationVariance,TaskCostVariance

All three of the sample queries get the same data.

Sample results of the Task query

Project	Task	TaskWork	TaskCost	TaskDuration	TaskDurationVariance	TaskCostVariance
ProjectA	T1	24.0 hrs	$404.00	24.0 hrs	0.0 hrs	$0.00
ProjectA	T2	8.0 hrs	$156.00	8.0 hrs	-16.0 hrs	-$272.00
ProjectA	T3	32.0 hrs	$564.00	32.0 hrs	8.0 hrs	$136.00
ProjectB	T1	48.0 hrs	$836.00	48.0 hrs	16.0 hrs	$272.00
ProjectB	T2	24.0 hrs	$428.00	24.0 hrs	0.0 hrs	$0.00
ProjectB	T3	40.0 hrs	$740.00	40.0 hrs	0.0 hrs	$0.00
ProjectB	T4	8.0 hrs	$168.00	8.0 hrs	-8.0 hrs	-$168.00

Remarks

Each entity set has a specific page-size limit. For information about page limits for on-premises and online ProjectData queries and how to set the on-premises page limit, see ProjectData - OData service reference.
