My requirement is to store the result of an sqlplus operation into a variable in my shell script. I need the result of the following operation which is in my .sh file
sqlplus 'user/pwd' @test.sql
I have already tried
testvar = 'sqlplus 'user/pwd'
@test.sql'
but that doesn't work.
EDIT::
I changed it to开发者_Python百科
testvar=sqlplus foo/bar@SCHM @test.sql
and it says
SQL*Plus:: not found [No such file or directory]
I tried with
testvar=$(sqlplus foo/bar@SCHM
@test.sql)
and it gives the same error. When I try without the variable assignment like below
sqlplus foo/bar@schm @test.sql
it works fine
Try this instead:
testvar=`sqlplus -s foo/bar@SCHM <<EOF
set pages 0
set head off
set feed off
@test.sql
exit
EOF`
-s switch will turn off all the header info when sqlplus launches. You also want to turn off the feedback, headers, and pagesize to 0. I am old school so I still use the back ticks :)
Employ backticks:
testvar=`sqlplus foo/bar @test.sql`
or should that be of syntactical eyesore:
testvar=$(sqlplus foo/bar @test.sql)
You clearly know to take the right sql*plus commands to limit superfluous output, yes? :) and of course beware the backticking will collapse the whitespace of the output.
As commands within $()
are executed in a subshell, make sure you have everything you need for the invocation of sqlplus exported. Right now you obviously stumbled into the PATH
issue.
The solutions here are all hacks.
Your sql file should look like this...
set termout off
set showmode off
set heading off
set echo off
set timing off
set time off
set feedback 0
set pagesize 0
set embedded ON
set verify OFF
spool courses.sh
SELECT 'term="' || sfrstcr_term_code || '";', 'subj="' || sfrstcr_subj_code || '";' FROM sfrstcr WHERE sfrstcr_pidm = 1234567;
spool off
The following shell script will read and print out the shell environment variables.
while read -r row; do
eval "$row"
echo "term=$term";
echo "subj=$subj";
done < courses.sh
It's important that all the variables are on one line, as the read command ensures that you can read each DB row per loop.
