TFS2015-列出在TFS 2015本地工作项目中使用了多少次标签

Question

​Hello,

​I am trying to write an SQL query to list all tags along with the number of how many times they were used in Work Items in TFS2015. I cannot find the connection between tbl_WorkItemCoreLatest, tbl_PropertyDefinition and tbl_TagDefinition that would point me to tags used on work items. I tried to go with the solution from here , but with no success. The query results seems not to match what I see directly in VSTS (eg. searching for a particular tag returns me work items from which some don't have that particular tag, almost as if TFS would store previous states of work items...?) If there's a way to do that with REST API, that will work as well.

Any help will be much appreciated.

Answer 1

You can use TFS REST API below to get all work items with System.Tags field, then calculate how many times they were used：

`http://tfs2015:8080/tfs/DefaultCollection/teamproject/_apis/wit/reporting/workitemrevisions?fields=System.Tags&includeLatestOnly=true&api-version=2`

Another simple way is creating a work item query with Tags column and open this query in Excel to filter the Tags column.
