SPO[OL] [file_name[.ext] [CRE[ATE] | REP[LACE] | APP[END]] | OFF | OUT]
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.
Enter SPOOL with no clauses to list the current spooling status.
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.
