Unix gurus,

I have a requirement in shell script where I have to connect to the DB and execute a script (Disabling Constraints) and subsequently do some loading process, if the disabling of the constraints is successful. Else, I have to write to the error file and abandon the process.

Error message is basically I want to take the first line in the Variable PM_Error.

The following is the Logic I wrote.

Is this valid? Any help on this is very much appreciated.

### SqlCall For Disabling the Constraints on anp_pmk_item_xref table
export PM_Error=`sqlplus -s $PM_UP <<END
      set heading off
      set verify off
      set feedback off
      set newp NONE
      @anp_pmk_item_xref_dis_cons.sql
/
END`

if [expr $PM_Error : 'ORA-'] 
then
   echo 'Unable to Disable the Constraints on anp_pmk_item_xref table>>${PM_ERRORFILE}
   export err_mess= substr($PM_Error,1,match($PM_Error,' '))
   echo $PM_Error>>${PM_ERRORFILE}
   exit
fi

Try something like this:

OUTPUT=`sqlplus -s scott/tiger <<END
      SELECT * FROM dual;
      EXIT 0;
END`

ERROR=`echo $OUTPUT | grep ORA-`

if [ "$ERROR" = "" ]; then
   echo 'No error - continue'
else
   echo 'Error - stop!'
fi

Do a "man" on the shell you are using. For example, if you use bash:

$ man bash

You should also be able to get it on the web. For example: http://www.gnu.org/software/bash/manual/bashref.html
