SPOOL Command Usage

This article explains :-

  • Known issues with SPOOL command and

  • Some of the common SET commands used with SPOOL command

SCOPE

This article is intended for SQL*Plus users.

SPOOL command in itself is a simple command. The issues are usually due to

the incorrect SQL*Plus environment setting (like linesize, heading, echo etc).

Following are some of the commands that have an impact of the output from spool.

More information can be found in SQL*Plus User's Guide and Reference documentation.

DETAILS

SET NUMWIDTH XX


E.g. select 345.34 from dual;

set numwidth 2 ===> ##

set numwidth 4 ===> 345

set numwidth 5 ===> 345.3

set numwidth 6 ===> 345.34

set numwidth 10 ===>____345.34 (where _ is a space)

SET NEWPAGE {1|n|None}


Sets the number of blank lines to be printed from the top of each page to

the top title.

0 - places a formfeed at the beginning of each page (including the

first page) and clears the screen on most terminals.

NONE - SQL*Plus does not print a blank line or formfeed between the report

pages.

SET SPACE


Determines the spacing between columns.

E.g. set space 1 ===> Col1_Col2 (_ is a space)

set space 5 ===> Col1_____Col2 (_ is a space)

SET LINESIZE


Determines the length of the line. If the linesize is too small then the

records will wrap around to the next line and the output may not be readable.

SET PAGESIZE


Sets the number of lines per page. If set to 0, then there are no pages.

SET FEEDBACK


Displays the number of records returned by a query when a query selects at

least n records. ON or OFF turns this display on or off. Setting feedback

to zero is equivalent to turning it OFF.

SET HEADING


Controls printing of column headings in reports.

ON prints column headings in reports; OFF suppresses column headings.

SET VERIFY


Lists each line of the command file before and after substitution.

SET TERMOUT


When running a script containing SQL commands and you have spooled the

output and if you do not want to see the output on your screen, you can

also add SET TERMOUT OFF to the beginning of the file and SET TERMOUT ON

to the end of the file.

E.g.

test.sql :

set termout off

spool t.t0

select* from emp;

spool off

exit

When running this file from SQL*Plus using @test.sql, the output will not

be display on the screen.

SET DOCUMENT


After you type DOCUMENT and enter [Return], SQL*Plus displays the prompt

DOC> in place of SQL> until you end the documentation. The "pound"

character (#) on a line by itself ends the documentation. If you have set

DOCUMENT to OFF, SQL*Plus suppresses the display of the block of

documentation created by the DOCUMENT command.

SET SQLPROMPT


If you do not want the SQL*Plus prompt to appear in the spooled file,

change the prompt to blank using set sqlprompt "".

SET TRIMSPOOL


Determines whether SQL*Plus allows trailing blanks at the end of each

spooled line. ON removes blanks at the end of each line. OFF allows

SQL*Plus to include trailing blanks.

E.g.

set numwidth 38

set NEWPAGE 0

set SPACE 0

set LINESIZE 80

set PAGESIZE 0

set FEEDBACK OFF

set HEADING OFF

set verify off

set doc off

set sqlprompt ""

set ECHO OFF

set trimspool on

Spool file not created in correct directory on Windows


Ensure that the SQL*Plus icon on the client PC desktop is created as a

shortcut and has the correct working directory (usually where you want

to create the spool file).

How does spool out know where to print on Unix


Set the following environment variables :

ORACLE_LPARGS='lpr arguments' e.g. -pr printername

ORACLE_LPPROG=/usr/local/bin/lpr'

SQLPATH and SPOOL


The SQLPATH registry entry or environment variable is used for the default

location/search path for stored SQL scripts and is not used for the SPOOL

command. This allows the user to be able to run scripts from SQL*Plus

without specifying a path. SPOOL command does not use this.
