Question: What are the important SQL*Plus
"set" commands?
Answer: Here are the set command for
SQL*Plus and thri functions:
set pages or pagesize ? this parameter
determines how many lines SQL*Plus will print to the screen before
starting a new page and reprinting the column headings. To
turn off column headings, set pages to zero. To have the
column headings appear only once, set pages very high (pages 999).
pages defaults to 14.
set line or linesize - determines how long a
line is. It defaults to 80 characters.
set feedback on/off ? This is the comment at the
end of your listing that tells you how many rows were returned.
If you turn feedback off, and you query returns no rows, you will
simply return to the SQL prompt.
set timing on - The most important SQL*plus set
command, it times the response time for SQL and PL/SQL, used for
tuning.
set verify off/on: This enables/disables
the feedback for substitution characters (with ampersands)
set trims or trimspool - normally SQL*Plus will
fill out a column with blank spaces. trimspool causes SQL*Plus
to not fill spaces at the end of a line when spooling the results.
You can also run the SQL*Plus "help set" command to see all of
the set commands:
