Oracle Spool to File in SQLPlus

I will explain Oracle Spool to File in SQLPlus in this post.

 

Oracle Spool to File

Sometimes you want to log the output of a MaxL Shell session to a file. Send standard output, informational messages, error messages, and/or warning messages generated by the execution of MaxL statements to a file.

If specified filename does not exist, it is created. If filename already exists, it is overwritten. If a directory path is not specified for filename, filename is created in the current directory of the MaxL Shell. Directories cannot be created using the spool command.

 

 

 

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.

 

 

Output of logging begins with spool on and ends with spool off as follows.
