Terminates SQL*Plus and returns control to the operating system.
Syntax
{EXIT|QUIT} [SUCCESS|FAILURE|WARNING|n|variable] [COMMIT|ROLLBACK]
Terms and Clauses
Refer to the following list for a description of each term or clause:
| {EXIT|QUIT} | Can be used interchangeably (QUIT is a synonym for EXIT). |
| n | Represents an integer you specify as the return code. |
| variable | Represents a user-defined or system variable (but not a bind variable), such as SQL.SQLCODE. EXIT variable exits with the value of variable as the return code. |
| SUCCESS | Exits normally. |
| FAILURE | Exits with a return code indicating failure. |
| WARNING | Exits with a return code indicating warning. |
| COMMIT | Saves pending changes to the database before exiting. |
| ROLLBACK | Executes a ROLLBACK statement and abandons pending changes to the database before exiting. |
Usage Notes
EXIT allows you to specify an operating system return code. This allows you to run SQL*Plus command files in batch mode and to detect programmatically the occurrence of an unexpected event. The manner of detection is operating system specific. See the Oracle installation and user's manual(s) provided for your operating system for details.
The key words SUCCESS, WARNING, and FAILURE represent operating-system-dependent values. On some systems, WARNING and FAILURE may be indistinguishable.
Note: SUCCESS, FAILURE, and WARNING are not reserved words.
The range of operating system return codes is also restricted on some operating systems. This limits the portability of EXIT n and EXIT variable between platforms. For example, on UNIX there is only one byte of storage for return codes; therefore, the range for return codes is limited to zero to 255.
If you make a syntax error in the EXIT options or use a non-numeric variable, SQL*Plus performs an EXIT FAILURE COMMIT.
For information on exiting conditionally, see the WHENEVER SQLERROR and WHENEVER OSERROR commands later in this chapter.
Example
The following example commits all uncommitted transactions and returns the error code of the last executed SQL command or PL/SQL block:
SQL> EXIT SQL.SQLCODE
The location of the return code depends on your system. Consult your DBA for information concerning how your operating system retrieves data from a program. See TTITLE in this chapter for more information on SQL.SQLCODE.
