TKPROF Report - Do not understand report

[Natik]

1. Could someone help me make sense of the report. I am not clear on what to make sense of when the:

Parse and Execute = 33
but the Misses in library cache during parse = 0.

call count cpu elapsed disk query current rows
------- ---- --- ------ ----- ----- ------- ----
Parse 33 0.00 0.00 0 0 0 0
Execute 33 0.00 0.05 0 66 331 33
Fetch 0 0.00 0.00 0 0 0 0
------- ---- ---- ---- ---- ---- ----- ----
total 66 0.00 0.05 0 66 331 33

Misses in library cache during parse: 0
Optimizer goal: CHOOSE
