In your SQL, do you have WHENEVER ERROR EXIT .something early on? The syntax allows you to set an exit code for your script to pick up, something like this perhaps:-

Code:

:
:
deck=sql1.sql                           # The deck of SQL commands you want to run
   sqlplus / <<-EOSQL                   # Logs on with external authentication.  For remote connection use sqlplus <<-EOSQL and include the credentials in the here document
   WHENEVER SQLERROR EXIT 1;            # Set the equivalent of a shell trap
   @$deck ;                             # Run what you want to do.
   exit ;                               # Terminate sensibly
EOSQL                                   # End the here document.
RC=$?

if [ $RC -ne 0 ]
then
   echo "Take some action because ${deck} failed with return code ${RC}"
fi

It's not tested at all because I no longer have an Oracle database to connect to. I might even have the here document wrong, but you get the idea.

I inherently shy away from putting credentials on the same line as the sqlplus because that would make them visible to a ps command whilst your code is running. There are plenty of examples on the board on how to do it properly.

I hope that this helps,
Robin

panel_show(3CURSES)					     Curses Library Functions					       panel_show(3CURSES)

NAME

       panel_show, show_panel, hide_panel, panel_hidden - panels deck manipulation routines

SYNOPSIS

       cc [ flag ... ] file ... -lpanel -lcurses [ library .. ]
       #include <panel.h>

       int show_panel(PANEL *panel);

       int hide_panel(PANEL *panel);

       int panel_hidden(PANEL *panel);

DESCRIPTION

       show_panel() makes panel, previously hidden, visible and places it on top of the deck of panels.

       hide_panel() removes panel from the panel deck and, thus, hides it from view. The internal data structure of the panel is retained.

       panel_hidden() returns TRUE(1) or FALSE(0) indicating whether or not panel is in the deck of panels.

RETURN VALUES

       show_panel() and hide_panel() return the integer OK upon successful completion or ERR upon error.
