Is there a solution for Ctrl C only to interrupt and not to exit SQL Plus in
windows.
As Andy pointed out, beginning with Oracle 18.2, pressing CTRL+C aborts a
long-running SQL and returns the cursor to the SQL> prompt, or is equivalent to
pressing Enter if the session is idle.
Apparently, this version of sqlplus.exe has added CTRL+C handling by calling
the function SetConsoleCtrlHandler, probably in response to enhancement request
8890996. You can find the string in this version of the executable:
C:\Temp>strings -q
C:\app\client\username\product\18.0.0\client_1\bin\sqlplus.exe | findstr
SetConsoleCtrlHandler
SetConsoleCtrlHandler
Interestingly, CTRL+BREAK during normal run of sqlplus seems to be left as
default. So, pressing that key combination will still abort.
If you're used to pressing CTRL+C to abort and exit Sqlplus, now you type exit
or quit, or undocumentedly, CTRL+Z and Enter or CTRL+Z alone. (But if you have
an uncommitted transaction, CTRL+Z will commit.) A minor annoyance is that if
you type the connect identifier wrong as in "sqlplus user/pass@nosuchdb", you
either wait about 20 seconds for the network timeout or use Task Manager or
some kill program to kill it. Neither CTRL+C nor CTRL+BREAK works.
