Ctrl-C Fails to Interrupt UPDATE Statement Using SQL*Plus 10g (Doc ID 554350.1)

Last updated on APRIL 03, 2019

Applies to:

SQL*Plus - Version to [Release Oracle10g]
Information in this document applies to any platform.
This problem can occur on any platform.
Generic UNIX platforms.


When run a script with UPDATE command using a 9i SQL*Plus executable and press Ctrl-C
when the script prompts for input variable values, the script execution is
interrupted and Oracle updates zero rows. This is the expected behavior.

Now, when run the same script using a 10g SQL*Plus executable, the script does not stop after
pressing Ctrl-C  <ENTER> and proceeds to update all the rows on the table.

In checking V$SQL, the command is seen there without the WHERE clause. Oracle ignores that there
is a WHERE clause, and hence updates all records in the table.

Here is a sample script, call it test.sql, based on EMP demo table:

Notice that the UPDATE statement did not get cancelled and all records in table were updated.
The same problem does not happen using SQL*Plus 9i. With SQL*Plus 9i, zero rows get updated.

This problem reproduces on HP, Linux, and Sun Solaris; hence, problem is UNIX generic.
It does not reproduce on Windows.


Upgraded to Oracle Server 10g.
