If what you are trying to do is something like:
- archive contents of live table from current period
- empty live table
- start collecting input again
you might want to look at the "rename" capability. Doing something
like:
rename <current> -> <old>
rename <empty template> -> <current>
will be much faster than trying to dump and empty a live table. With
"rename" you'll have your data from the last period in "<old>" so can
handle it at will.
You'll want to look at what a rename vs. truncate vs. delete do to
make certain there isn't something with one of them that might cause
you a problem.
