Finding if particular operation(edit,delete,merge) is done from Command column values of tbl_version

Hi,

We are using TFS 2012. We noticed tbl_version keeps information about changeset and command column represents the operation done at that changeset. I got this list of commands after searching

    * Edit = 2		    * Type = 4		    * Add folder = 5		    * Add file = 7		    * Rename = 8		    * Rename,edit = 10		    * Delete = 16		    * Delete,rename = 24		    * Undelete = 32		    * Undelete,edit = 34		    * Branch = 68		    * Branch,delete = 84		    * Merge = 128		    * Merge, edit = 130		    * Merge,type,edit = 134		    * Merge, rename, edit = 138		    * Merge,delete = 144		    * Merge,delete,rename = 152		    * Merge,undelete = 160		    * Merge,undelete,edit = 162		    * Merge,branch = 196		    * Merge,branch,edit = 198		

My problem is how to find out if some operation is done in particular changeset using command values? I know can find out easily if only single operation is done by using command values directly. But how can I find out in case of multiple operations(Where command values are added I.e merge,edit=128+2=130)?
