What is the purpose of the spool command in Oracle?
In Oracle, the spool command is used to output SQL query results to a file. By using the spool command, users can save SQL query results to a file for later viewing or processing. This is very useful when needing to save large amounts of query results or generate reports. The syntax of the spool command is as follows:
SPOOL file_name
The file_name is the name of the file where the output results will be saved. Users can use the command “spool off” to stop the output to the file and close it.
SPOOL OFF
The spool command in Oracle database allows you to easily save query results to a file for future reference.
