TEMP_TABLESPACE_SPACE

Hi,
Can any one tell me which statement uses more TEMP SPACE , select / insert /update like that ...which one occupy more space in TEMP TABLESPACE...
Thanks,

Depends. If your select does a sort that needs to use temp segments, it can use a lot, a cartesian join can use a whole lot, big sort area or PGA could use less. If you have a lot of indices, dml can use a lot. You can see v$sort_usage for your system. See the classic MOS Temporary Segments: What Happens When a Sort Occurs [ID 102339.1] for a list of what statements use temp.
What are you really asking?
