task and subtask in TFS - tfs

I'd like to know which is parent/child relationship for task in th TFS datawarehouse or db.
For example the parentID=15662 and childID=15667, where I can find this information in the DW or db?

I think this will get you close to what you need. It just pulls the parent UserStory with a particular ID and all of it's children. The work item types may need to be changed based on your team project template. You can look at the different link types in DimWorkItemLinkType and adjust the query accordingly to get the desired result.
USE Tfs_Warehouse
GO
SELECT story.System_ID AS StoryID
, story.System_Title AS StoryTitle
, task.System_ID AS TaskID
, task.System_Title AS TaskTitle
, linkType.ReferenceName
, linkType.LinkName
FROM CurrentWorkItemView story
LEFT JOIN dbo.vFactLinkedCurrentWorkItem linkToStory
ON story.WorkItemSK = linkToStory.SourceWorkItemSK
LEFT JOIN CurrentWorkItemView task
ON linkToStory.TargetWorkitemSK = task.WorkItemSK
AND task.System_WorkItemType = 'Task'
LEFT JOIN dbo.DimWorkItemLinkType linkType
ON linkToStory.WorkItemLinkTypeSK = linkType.WorkItemLinkTypeSK
WHERE story.System_WorkItemType = 'User Story'
AND story.System_ID = 15662

Invalid table alias when joining multiple tables in hive

Can someone identify why this multi-table join is not accepted? When I bring in the third table, it then fails with invalid table alias. I am not seeing what is wrong:
This works (two table):
select
a.ri as `R_ID`
,oc3.name as `RET`
,a.rch as `RC`
from dev.sl a join dev.codes oc3
on (a.pk_business = oc3.pk_business
and a.pk_data_source = oc3.pk_data_source
and a.pk_frequency = oc3.pk_frequency
and oc3.pk_data_state = '123'
and oc3.code = a.ri and oc3.codeset = 'xyz')
Then add a third table and it fails:
(Three table):
select
a.ri as `R_ID`
,oc3.name as `RET`
,a.rch as `RC`
from dev.sl a join dev.codes oc3
on (a.pk_business = oc3.pk_business
and a.pk_data_source = oc3.pk_data_source
and a.pk_frequency = oc3.pk_frequency
and oc3.pk_data_state = '123'
and oc3.code = a.ri and oc3.codeset = 'xyz') join dev.items b
on (b.pk_business = a.pk_business
and b.pk_data_source = a.pk_data_source
and b.pk_frequency = a.pk_frequency
and b.pk_data_state = '123'
and a.ii = b.item_id
and a.cc = b.country_code)
SemanticException [Error 10009]: Line 1:2920 Invalid table alias 'a':
I have an update - it seems that this was caused by having one table created as an updatable table (TBLPROPERTIES ('transactional'='true')), and one without, and with my session settings of:
SET hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
SET hive.support.concurrency=true;
SET hive.enforce.bucketing=true;
SET hive.exec.dynamic.partition.mode=nonstrict;
This caused the problem. On another session without the settings AND repointing to an identical table "a" created as a non-ACID type table, the multi-table join worked fine. I don't know enough about HIVE to know why - I suspect that a transactional and non-transactional table cannot be joined in the same "transaction" (select statement).
One more update - It may not be due to the transactional table. With additional testing, I now also see it happens with non-transactional tables as well. It seems that the three table join works when I execute it from a putty session directly on the server, but when I use SQL Developer, it will produce the aforementioned error. It appears to be an issue with SQL Developer, but why still is unknown.

Yii2: How to do a inner join of three tables?

I have a many-to-many relationship so I have three tables (administrators, offices and the intermediate table):
I need to do a very simple innerjoin of the three tables to show lastnames and their offices with Active Record. I tried but I couldn't.
This is what I tried:
$admins = Admins::find()
->joinWith(Oficinas::tableName())
->all();
echo '<pre>';
print_r($admins);
echo '</pre>';
die();
Also I would like to know how to show the SQL query so it can help me to find a solution.
You need to specify the relation name for joinWith() rather than table names. Since there isn't any info on the relation names I will use simple innerJoin using table names as per your requirements to display the last name and the office name for the admins.
Admins::find()
->alias('a')
->select('a.lastnameadm, o.nombreofi')
->innerJoin('admin_oficinas ao','ao.idadm = a.idadm')
->innerJoin('oficinas o','o.idofi = ao.idofi')
->all();
Try this:
TABLE_NAME_1::find()
->join('inner join',
'table_name_2',
'table_name_2.column = table_name_1.column'
);
->join('inner join',
'table_name_3',
'table_name_3.column = table_name_2.column'
)->all();
but if you can also use Via like the following example:
public function getClassschedule()
{
return $this->hasOne(TABLE_NAME_2::className(), ['table_name_1.column' => 'table_name_2.column'])
->via('tableName3');
}
when excuded, the results should be obtained like the previous example. so there's no need to repeated relations. full documentation can be seen here :

Masterdata Services udpValidateModel Procedure

i've got a few tables in MDS.
One table (clients) ist filled via SQL and the other one is a masterdata table (country) filled by hand.
I have a business rule on table clients:
"Name must be unique" and no b-rule on Country.
I want to validate the data PROGRAMMATICALLY i do not want to CLICK "apply business rules" in explorer window on the webinterface.
I found several threads about how to use the sp mentioned in the title (udpValidateModel) to validate all entities in a model.
well...this thing does nothing. I can see the validationStatus in each of my tables "Awaiting Revalidation" after changing business rules or update data via sql. It doesnt matter what i do the status wont change (neither the validation icons in webui).
i also tried validateentity but the same "nothing" happens.
The SP below:
DECLARE #User_ID int
DECLARE #Model_ID int
DECLARE #Version_ID int
SET #User_ID = (SELECT ID FROM [MasterDataServices].[mdm].[tblUser] where userName = SYSTEM_USER )
SET #Model_ID = (SELECT Top 1 Model_Id FROM [MasterDataServices].[mdm].[viw_SYSTEM_SCHEMA_VERSION]
WHERE Model_MUID = 'MYMODELID')
SET #Version_ID = (SELECT Top 1 VersionNbr FROM [MasterDataServices].[mdm].[viw_SYSTEM_SCHEMA_VERSION]
WHERE Model_MUID = 'MYMODELID'
ORDER BY ID DESC )
EXECUTE [MasterDataServices].[mdm].[udpValidateModel] #User_ID, #Model_ID, #Version_ID, 1
Can anyone help?
SP 'udpValidateModel' works perfectly fine, looks like the parameters you are populating is not correct.
You may correct this as below and try; make sure that the system user has full authorization for the model.
SET #User_ID = (SELECT ID FROM [MasterDataServices].[mdm].[tblUser] where userName = SYSTEM_USER )
SET #Model_ID = (SELECT Top 1 Model_Id FROM [MasterDataServices].[mdm].[viw_SYSTEM_SCHEMA_VERSION]
WHERE Model_MUID = 'MYMODELID')
SET #Version_ID = (SELECT Top 1 VersionNbr FROM [MasterDataServices].[mdm].[viw_SYSTEM_SCHEMA_VERSION]
WHERE Model_MUID = #Model_ID
ORDER BY ID DESC )

Access the Kanban Column (a Team-Specific Field) for a Work Item

Is there a way to programmatically access the "Kanban Column" for a WorkItem using the TFS 2012 API?
Using the Scrum 2.2 template, the history of a Bug or Product Backlog Item shows "[MyProject\MyTeam] Kanban Column" as a changed field whenever a work item is dragged between Kanban columns on the Board, but the field is not accessible when specifically retrieving a work item through the TFS API.
It also shows up as a changed field in the WorkItemChangedEvent object when implementing the ProcessEvent method on the Microsoft.TeamFoundation.Framework.Server.ISubscriber interface.
Workaround:
A coworker found a blogpost about creating a read-only custom field to persist the value of the Kanban Column, taking advantage of the WorkItemChangedEvent to capture the latest value. It is then possible to query on this column. One problem with this approach is that only a single team's Kanban Column can be tracked.
Update:
According to this blogpost, the Kanban Column is not a field, rather a "WIT Extension". This may help lead to an answer.
I've found a way to read the value using the TFS 2013 API, inside the ISubscriber.ProcessEvent method:
var workItemId = 12345;
var extService = new WorkItemTypeExtensionService();
var workItemService = new WorkItemService();
var wit = workItemService.GetWorkItem(requestContext, workItemId);
foreach (var wef in extService.GetExtensions(requestContext, wit.WorkItemTypeExtensionIds))
{
foreach (var field in wef.Fields)
{
if (field.LocalName == "Kanban Column" || field.LocalName == "Backlog items Column")
{
// Access the new column name
var columnName = wit.LatestData[field.Field.FieldId];
}
}
}
If you are prepared to dig into the database you can mine this information out. I don't fully understand the modelling of the teams in TFS yet but first you need to work out which field id the team of interest is storing the Kanban state in as follows (TFS 2012):
USE Tfs_DefaultCollection
SELECT TOP(10)
MarkerField + 1 as FieldId,*
FROM tbl_WorkItemTypeExtensions with(nolock)
JOIN tbl_projects on tbl_WorkItemTypeExtensions.ProjectId = tbl_projects.project_id
WHERE tbl_projects.project_name LIKE '%ProjectName%
Then replace XXXXXXXX below with the FieldId discovered above
SELECT TOP 1000
wid.Id,
wia.State,
wid.StringValue as Kanban,
wia.[Work Item Type],
wia.Title,
tn.Name as Iteration
FROM tbl_WorkItemData wid with(nolock)
JOIN WorkItemsAre wia on wia.ID = wid.Id
JOIN TreeNodes tn on wia.IterationID = tn.ID
WHERE FieldId = XXXXXXXX and RevisedDate = '9999-01-01 00:00:00.000'
ORDER BY Id
I am not familiar with the Scrum 2.2 template, but the works are the same for CMMI or Scrum templates when it comes to TFS Work Item tracking.
Try something like this:
public string GetKanbanColumn(WorkItem wi)
{
if (wi != null)
{
return wi["Kanban"].ToString();
}
return string.Empty;
}
Depending on the actual name of the column, specified in the Work Item Template XML file. Hope this helps.

What tfs 2010 object references are available for Tfs_DefaultCollection.dbo.tbl_ReleaseNoteDetails

We have a Team Project Collection Source Control Setting for Check-in Notes that requires each check-in to capture a "Tracking Number". This number is external to TFS. I need to search for all the changesets that have a specific Tracking number.
The resulting changeset list tells me what to GetLatest on, for our monthly deployment.
-- We don't use Work Items
This .SQL gives me the list I'm looking for. I want to access this in code from Visual Studio.
SELECT ReleaseNoteId, FieldName, BaseValue
from Tfs_DefaultCollection.dbo.tbl_ReleaseNoteDetails
where ReleaseNoteId in (SELECT ReleaseNoteId
FROM Tfs_DefaultCollection.dbo.tbl_ReleaseNote
where DateCreated between '2013-01-01' and '2013-01-31')
and FieldName = 'Tracker #'
and BaseValue = '18570'
What object references are available for Tfs_DefaultCollection.dbo.tbl_ReleaseNoteDetails?
There is no 1to1 object reference in the TFS API, because you usually don't work on the structure like the database looks like.
What I understand from your description, you have the information you need in the changesets. In that case you could use the VersionControlServer to get the changesets and get the information from there.
TfsTeamProjectCollection tfsConnection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://TFS:8080/TFS/DefaultCollection"));
VersionControlServer sourceControl = (VersionControlServer)tfsConnection.GetService(typeof(VersionControlServer));
IEnumerable changesets = sourceControl.QueryHistory(ServerPath, VersionSpec.Latest, 0, RecursionType.Full, null, new DateVersionSpec (new DateTime(2013,1,1)), new DateVersionSpec (new DateTime(2013,1,31)), Int32.MaxValue, true, false);
foreach (Changeset change in changesets)
{
// check where the information is stored in the changeset, may change.Changes
}
Just an idea to get in the right direction.
If you want easy querying and searching, you're better off creating a new work item field and associate the work item during checkin. Work items have complete querying capabilities in the UI and are even transported to the Reporting warehouse.
You could retrieve the history for a specific folder, date range etc using a QueryHistoryParameters object and then iterate over the CheckinNotes to filter:
var projectCollection = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(
new Uri("http://localhost:8080/tfs/DefaultCollection"));
var versionControlServer = projectCollection.GetService<VersionControlServer>();
var query = new QueryHistoryParameters("$/Scrum/**", RecursionType.Full);
var changesets = server.QueryHistory(query);
changesets.Where(cs => cs.CheckinNotes.Any(note => note.PropertyName == "Tracker #"
&& note.Value == "18570"))
This is not going to be terribly fast. To get a quick solution, use work item association.
