Update work items by WIQL query

Updates the same column(s) on every work item that matches a WIQL query. The query in WITH selects the target items; the SET clause defines the new values. Use this to bulk-update title, state, or other fields for a set of items (e.g. all tasks in a sprint). Verify the query scope before running.

UPDATE WorkItems
Set Title='New Title - Updated on <<FUN_NOW>>'
Where 1=1 
WITH(Query='SELECT * FROM WorkItems Where [System.TeamProject]=''MyProject'' AND ([System.Id]=6469 OR [System.Id]=6468) ')
