Hi,
in sqlloader, I have to clean up one table before
loading fresh data.
Which one is better option in the control file?
TRUNCATE INTO TABLE ITM_MSTR_TEMP
OR
REPLACE INTO TABLE ITM_MSTR_TEMP
And why?
TIA,
Debby

actaully,
even if you specify replace,
an internal truncate is used by sql*loader is different (it will re-use tables extents) and is slower (a bit...not a big difference unless it is a real huge table).
I prefer to truncate the table before loading the data
