Command Reference, 3 of 52

@ ("at" sign)


Runs the specified command file.


@ file_name[.ext] [arg...]

Terms and Clauses

Refer to the following list for a description of each term or clause:


      Represents the command file you wish to run. If you omit ext, SQL*Plus assumes the default command-file extension (normally SQL). For information on changing the default extension, see the SUFFIX variable of the SET command in this chapter.

      When you enter @ file_name.ext, SQL*Plus searches for a file with the filename and extension you specify in the current default directory. If SQL*Plus does not find such a file, SQL*Plus will search a system-dependent path to find the file. Some operating systems may not support the path search. Consult the Oracle installation and user's manual(s) provided for your operating system for specific information related to your operating system environment.


      Represent data items you wish to pass to parameters in the command file. If you enter one or more arguments, SQL*Plus substitutes the values into the parameters (&1, &2, and so forth) in the command file. The first argument replaces each occurrence of &1, the second replaces each occurrence of &2, and so forth.

      The @ command DEFINEs the parameters with the values of the arguments; if you run the command file again in this session, you can enter new arguments or omit the arguments to use the current values.

    For more information on using parameters, refer to the subsection "Passing Parameters through the START Command" under "Writing Interactive Commands" in Chapter 3.

Usage Notes

You can include in a command file any command you would normally enter interactively (typically, SQL, SQL*Plus commands, or PL/SQL blocks).

An EXIT or QUIT command used in a command file terminates SQL*Plus.

The @ command functions similarly to START.

If the START command is disabled (see "Disabling SQL*Plus, SQL, and PL/SQL Commands" in Appendix E), this will also disable the @ command. See START in this chapter for information on the START command.

SQL*Plus removes the SQLTERMINATOR (a semicolon by default) before the @ command is issued. A workaround for this is to add another SQLTERMINATOR. See the SQLTERMINATOR variable of the SET command in this chapter for more information.
