SPOOL

Syntax

SPO[OL] [file_name[.ext] [CRE[ATE] | REP[LACE] | APP[END]] | OFF | OUT]

Stores query results in a file, or optionally sends the file to a printer.

Terms

file_name[.ext]

Represents the name of the file to which you wish to spool. SPOOL followed by file_name begins spooling displayed output to the named file. If you do not specify an extension, SPOOL uses a default extension (LST or LIS on most systems). The extension is not appended to system files such as /dev/null and /dev/stderr.

CRE[ATE]

Creates a new file with the name specified.

REP[LACE]

Replaces the contents of an existing file. If the file does not exist, REPLACE creates the file. This is the default behavior.

APP[END]

Adds the contents of the buffer to the end of the file you specify.

OFF

Stops spooling.

OUT

Stops spooling and sends the file to your computer's standard (default) printer. This option is not available on some operating systems.

Enter SPOOL with no clauses to list the current spooling status.

Usage

To spool output generated by commands in a script without displaying the output on the screen, use SET TERMOUT OFF. SET TERMOUT OFF does not affect output from commands that run interactively.

You must use quotes around file names containing white space.

To create a valid HTML file using SPOOL APPEND commands, you must use PROMPT or a similar command to create the HTML page header and footer. The SPOOL APPEND command does not parse HTML tags.

SET SQLPLUSCOMPAT[IBILITY] to 9.2 or earlier to disable the CREATE, APPEND and SAVE parameters. See SQL*Plus Compatibility Matrix to determine what functionality is controlled by the SET SQLPLUSCOMPAT[IBILITY] command.

Examples of SPOOL Command

To record your output in the new file DIARY using the default file extension, enter

SPOOL DIARY CREATE

To append your output to the existing file DIARY, enter

SPOOL DIARY APPEND

To record your output to the file DIARY, overwriting the existing content, enter

SPOOL DIARY REPLACE

To stop spooling and print the file on your default printer, enter

SPOOL OUT

set linesize (라인당 출력될 문자 수)

OAS — Tue, 12 Jan 2010 08:12:07 +0900

테이블의 전체 내용을 출력하다보면 2라인에 걸쳐 출력됨을 확인 할수 있다. 오라클은 기본적으로 한 라인에 출력할 수 있는 문자수가 80자로 제한되어 있다. 하지만 80자 이상이기 때문에 2라인에 걸쳐 출력될수 있다.오라클은 라인당 출력될 문자수를 변경 하기 위한 시스템 변수로 LINESIZE를 제공한다.

SQL> set linesize;
P2-0267: linesize 옵션이 0 범위(1 에서 32767)를 초과했습니다.
set linesize 함수의 범위는 1~32767까지 옵션 범위 설정 할수 있나보다.
