If you don't have a stopwatch/timer and want to measure elapsed periods of time, you can SQL*Plus Built-in Timers with the following commands:

  • TIMING - Displays number of timers.
  • TIMING START [name] - Starts a new timer with or without a name.
  • TIMING SHOW [name] - Shows the current time of the named or not-named timer.
  • TIMING STOP [name] - Stops the named or not-named timer.

SQL> TIMING SHOW timer_1
timing for: timer_2
Elapsed: 00:00:19.43

(some seconds later)
