Passing a parameter from a shell script to sqlplus

Shell Programming and Scripting

Hi All,

I'm new to Linux and scripting, apologies in advance for 'stupid' questions.

Please help... Im writing a script that calls a sqlplus script but the sqlplus requires inputs and i cant seem to get this to work.

here is my code.

#!/bin/sh
TERM=vt100
export TERM
WORKDIR=/mnt/sr_scripts/PER
export WORKDIR
cd $WORKDIR
 
DEV="dev" #this is dev environment.
TEST="test" #this is TEST environment.
 
echo "Enter Environment"
read mENV
echo "Enter a valid PERSON_ID for the employee:"
read PID
echo "Display Payroll Element Entries (Y|N):"
read PEE

if [ "$mENV" == "$DEV" ]; then
 sqlplus -silent apps/apps @PER12.sql
 expect "Enter a valid PERSON_ID for the employee:"
 send "$PID"
 expect "Display Payroll Element Entries (Y|N):"
 send "$PEE"
elif [ "$mENV" == "$TEST" ]; then
 sqlplus -silent apps/apps123 @PER12.sql
 expect "Enter a valid PERSON_ID for the employee:"
 send "$PID"
 expect "Display Payroll Element Entries (Y|N):"
 send "$PEE"
fi

Please note that the first step of the script executes, im able to kick off the sql script but the sql script dont accept the parameters ie: PID and PEE... It just prompts for it again.

Thanking you in advance.

Regards
Mahomed

Hi Durden_Tyler,

Thank you kindly for your reply.

Please excuse my dumb question...

where must this go? in the sql script?
:confused::confused:

cat -n per12.sql
1 begin
2 dbms_output.put_line ('You entered PID = ' || '&1');
3 dbms_output.put_line ('You entered PEE = ' || '&2');
4 end;

Yes, that is my sample SQL script.
I don't know the contents of your SQL script - "PER12.sql", so I created my own sample script to demonstrate how you could pass parameters to it.

Since you put the "expect" command after calling "PER12.sql", my guess is that your SQL script prompts for the inputs when it is run directly in sqlplus. So, I'd think you have an "accept" statement in there somewhere in your SQL script that accepts substitution variables.

What I meant to say in my post was - you could remove the named substitution variables in your original "PER12.sql" script and use "&1", "&2" instead. That way you can pass them in the invocation line itself.

Hi Durden_Tyler,

Thank you very much for your help.

You are correct, the PER12.sql script does have the ACCEPT statement, I will now modify and try...

before:
ACCEPT v_personId PROMPT 'Enter a valid PERSON_ID for the employee: '
PROMPT
ACCEPT v_payElements PROMPT 'Display Payroll Element Entries (Y|N): '

After:
ACCEPT v_personId = &1
REM PROMPT 'Enter a valid PERSON_ID for the employee: '
REM PROMPT
ACCEPT v_payElements = &2
REM PROMPT 'Display Payroll Element Entries (Y|N): '

Let me give this a bash.

Cheers!!!
