As explained earlier in the chapter, the SQL buffer is overwritten with every new SQL command you enter in SQL*Plus. If you want to save the contents of the SQL buffer, you can use the SQL*Plus SAVE command. The SAVE command creates a script file containing the contents of the SQL buffer. If a script file already exists, you can specify (with the options APPEND or REPLACE) what you want the SAVE command to do in that case. The APPEND option is useful if you want to save all your SQL commands in one single file; for example, to print that file later. Under Microsoft Windows, the options for saving the contents of the SQL buffer are also available via the File pull-down menu of SQL*Plus, as shown in Figure 2-6.

SQL> save BLA SP2-0540: File "BLA.sql" already exists. Use "SAVE filename[.ext] REPLACE". SQL> save BLA replace Created file BLA.sql SQL> Note the error message after the second SAVE BLA attempt; REPLACE (or APPEND) is mandatory if a file already exists. We have created two script files. These script files get the extension .SQL by default. If you prefer to use a different file name extension, you can change it with the SQL*Plus SUFFIX setting.
Running SQL*Plus Scripts
You can load script files saved with the SAVE command back into the SQL buffer with the GET command, followed by the name of the script. For example, you might reload a script and then edit it. If you want to load a script file and immediately execute it, you can use the START command (to get and run the script), as shown in Listing 2-16. Listing 2-16. Using the SQL*Plus GET and START Commands SQL> GET BLA 1* select * from courses SQL> START BLI DEPTNO -----10 20 30 40 SQL> Listing 2-17 shows that you can also use the @ shortcut for the SQL*Plus START command.
