RE: Parse Vs Execute

Don't do this:

	Loop
		Parse
		Execute
		Fetch
	End loop

Do this:

	Parse
	Loop
		Execute
		Fetch
	End loop

If you parse inside your loop, then all that using bind variables will gain you is a reduced "hard parse" count. If you parse outside the loop (in which case, you MUST use bind variables), then you reduce your number of parse calls. A "soft parse" is a little cheaper than a "hard parse." NO PARSE is a lot cheaper than a "soft parse."

Hi List,

Almost fro all SQLs I am getting Prase count is same as Execute count. How to reduce parse count?

1. We are using bind variable
2. session_cached_cursors set to 100

  call count cpu elapsed disk query current rows

• ------ -------- ---------- ---------- ---------- ----------

  ---

  Parse 11 0.01 0.02 0 0 0 0 Execute 11 0.00 0.00 0 0 0 0 Fetch 22 0.01 0.00 0 33 44 110
• ------ -------- ---------- ---------- ---------- ----------

  ---

  total 44 0.02 0.02 0 33 44 110

Any somebody give more hint on this?

Thanks
Jay
