Note the effects of the vertical bar (|) in the COL SALARY command and the LIKE option for the COMMISSION column.

The NEW_VALUE feature of the COLUMN command is very nice, and you can use it for various tricks in SQL*Plus scripts. As you can see in Listing 11-29, the user-defined BLAH variable remembers the last EMPNO value for you. Listing 11-29.

The SQL*Plus TTITLE and BTITLE Commands
As you have seen so far, the SQL*Plus COLUMN command allows you to influence the report layout at the column level, and you can influence the overall page layout with the SQL*Plus SET PAGESIZE and SET LINESIZE commands. You can further enhance your SQL*Plus reports with the SQL*Plus TTITLE and BTITLE commands, which allow you to add page headers and footers to your report. The syntax is as follows: SQL> ttitle [<print-spec> {<text>|<variable>}...] | [OFF|ON] SQL> btitle [<print-spec> {<text>|<variable>}...] | [OFF|ON] As Listing 11-30 shows, you can also use these commands to display their current settings (by specifying no arguments) or to enable/disable their behavior with ON and OFF. Listing 11-30. Using TTITLE and BTITLE SQL> set pagesize 22 SQL> set linesize 80 SQL> ttitle left 'SQL*Plus report' > right 'Page: ' format 99 SQL.PNO > skip center 'OVERVIEW' > skip center 'employees department 30' > skip 2 SQL> btitle col 20 'Confidential' tab 8 > 'Created by: ' SQL.USER SQL> / SQL*Plus report OVERVIEW employees department 30 month EMPNO last_name BDATE salary ------ -------------------- ----------- --------7499 ALLEN 20-FEB-1961 $1600.00 7521 WARD 22-FEB-1962 $1250.00

Note that we use two predefined variables: SQL.PNO for the page number and SQL.USER for the current username. The TTITLE and BTITLE commands have several additional features. SQL*Plus also supports the REPHEADER and REPFOOTER commands, which allow you to add headers and footers at the report level, as opposed to the page level. See SQL*Plus User s Guide and Reference for more information about these commands.
