Youcan use SET TERMOUT OFF to prevent the script output from displaying on the screen.When running a script, you should include the full path name unless the script islocated in the directory where SQL*Plus was launched.10.2.7 Spooling From SQL*PlusThe SPOOL command can be used to direct the output from SQL*Plus to a disk file,which enables you to save the output for future review.To start spooling the output to an operating system file, you can enter:SQL> SPOOL my_log_file.logIf you want to append the output to an existing file:SQL> SPOOL my_log_file.log APPENDTo stop spooling and close a file, enter the following:SQL> SPOOL OFF10.2.8 Using Variables With SQL*PlusYou can write queries that use variables to make your SELECT statements moreflexible.
