Iterator Catchall Showplan Operator
The catchall icon is displayed when a suitable icon for the iterator cannot be found by the logic that produces graphical showplans. The catchall icon does not necessarily indicate an error condition. For more information, contact Customer Service and Support.
There are three catchall icons: blue (for iterators), orange (for cursors), and green (for Transact-SQL language constructs).
