Question

I ve got the following WIQL query for a TFS project:

string query = "SELECT * FROM Issue WHERE [System.TeamProject] = @Project "+
                "AND [Assigned To] IN (@AssignedTo)";

Dictionary<string, object> parameters = new Dictionary<string, object>();
parameters.Add("Project","test");
parameters.Add("AssignedTo"," chris , tfsuser ");
WorkItemStore.Query(query, parameters);

This is being run via the .NET TFS API.

My problem is with the AssignedTo parameter. How is this meant to be specified? I ve tried it as a string[], List<string> as well as with and without quotes as above. Each one doesn t seem to work.

Answer 1

I understand what you re trying to do, but it doesn t look like it s possible. The query that you want is this:

WHERE [System.AssignedTo] in ( John Smith ,  Jane Citizen )

Which is semantically the same as this:

WHERE [System.AssignedTo] =  John Smith  OR [System.AssignedTo] =  Jane Citizen

The only way I can work out how to achieve it in code is by specifying the identities as separate parameters:

TfsTeamProjectCollection tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://localhost:8080/tfs/"));
WorkItemStore wis = tfs.GetService<WorkItemStore>();

Dictionary<string, string> values = new Dictionary<string, string>();

values.Add("parameter1", "John Smith");
values.Add("parameter2", "Jane Citizen");

Query query = new Query(wis, "SELECT [System.Id] FROM WorkItems WHERE [System.AssignedTo] IN (@parameter1, @parameter2)", values);

WorkItemCollection workItems = wis.Query(query.QueryString);
WorkItem workItem = workItems[0];

Answer 2

Assigned To field is actually [System.AssignedTo]. I don t believe using the display name of the field will work.
