10. SET TERMOUT SET TERMOUT OFF suppresses the display so that you can spool output from a script without seeing it on the screen If both spooling to file and writing to terminal are not required use SET TERMOUT OFF in SQL scripts to disable terminal output SET TERMOUT is not supported in iSQL Plus SET TRIMOUT ON SET TRIMSPOOL ON UNDEFINE SET TRIMOUT ON or SET TRIMSPOOL ON removes trailing blanks at the end of each displayed or spooled line Setting these variables ON can reduce the amount of data written However if LINESIZE is optimal it may be faster to set the variables OFF The SQL Plus output line is blank filled throughout the query processing routines so removing the spaces could take extra effort SET TRIMOUT and SET TRIMSPOOL are not supported in iSQL Plus Deletes substitution variables that you defined either explicitly with the DEFINE command or implicitly with an argument to the START command or COLUMN NEW_VAL1OLD_VAL Use the UNDEFINE command to remove unnecessary substitution variables This can reduce the time taken for any operation that uses amp new_value or old_value variables 8 10 SQL Plus User s Guide and Reference 9 SQL Plus Security This chapter describes the available methods for controlling access to database tables SQL Plus and iSQL Plus commands and iSQL Plus access It covers the following topics a PRODUCT_USER_PROFILE Table a Disabling SQL Plus SQL and PL SQL
