that particular record will be cleaned up immediately (or at least when the transaction gets some cycles). The dedicated garbage collection thread should clean up all the records on a page, but not until

expression in the grouping clause, saves keystrokes and bytes, but it is not a way of saving processing cycles! In addition to the required items, the grouping list may also contain: • Columns from the source so in a FROM clause. A great benefit of recursive CTEs is that they use far less memory and CPU cycles than an equivalent recursive stored procedure. Execution Pattern The execution pattern of a recursive
