I'd like to ask a question, which is interesting for me for a long time. Let's assume I have made a SELECT. the result set of this query contains many records. Then I made one fetch. Where in Oracle are the resting records of a result set stored?
All result sets of queries are stored in CURSORs defined either implicitly (by Oracle) or explicitly (by you). A cursor is really just a pointer (name) to an area in memory (the SGA or System Global Area). When a select statement runs, the rows that satisfy the query are placed into a named area of memory and the pointer is initially set to just above the first record. When you fetch a record, the pointer moves to the next record and retrieves it until it returns all the rows from the named memory area.
