Passing variables to sql in a unix shell script
Posted on 2004-03-23
Hi
Hopefully this is the correct area for this question- was not sure if it should come under UNIX or Oracle.
Been struggling all morning with this and wondered if anyone could help. Basically I'm creating a variable from a sql statement and then passing this variable into another sql statement as a parameter and it does not work. If I create the variable manually i.e EOD_TYPE="'EOD'" and then pass the parameter to the 2nd sql statement as ${EOD_TYPE} it works, if I use a select to create the variable i get the following error:
SP2-0042: unknown command "'EOD'" - rest of line ignored.
It's quite a short script so I'll paste it below for reference.
thanks in advance
Paul
#!/bin/ksh
#EOD_TYPE="'EOD'"
EOD_TYPE=`sqlplus -s / <<EOF
set head off
set feedback off
set pages
select decode(to_char(bus_date,'D
EOF`
EOD_RUN_TIME=`sqlplus -s / <<EOF
set head off
set feedback off
set pages
select proc_time_min*60 from eod_run_time where eod_type=${EOD_TYPE};
EOF`
echo $EOD_RUN_TIME

Which sqlplus is causing error? If the first one works correctly does it set the value of EOD_TYPE correctly? Include echo $EOD_TYPE after the first sqlplus in your script.
both sql's work OK - it's the 2nd one that fails if the variable is created via the 1st sql. If I put the echo in I get 'EOD' which is what I would expect.
I've a feeling that you've got some extra characters at the start of EOD_TYPE
so that it is effectively executing :
select proc_time_min*60 from eod_run_time where eod_type=
'EOD';
Maybe something in a glogin.sql script ?
You can try something like
sqlplus -s / <<EOF
set serveroutput on size 100000
declare
v_char varchar2(2000);
begin
select substr(dump('${EOD_TYPE}')
dbms_output.put_line(v_cha
end;
.
/
EOF
to see what SQL is getting in that variable
Ideally you want something like
Typ=96 Len=3: 69,79,68
(ie a three character value with just ASCII characters)

Using SQL Scripts we can save all the SQL queries as files that we use very frequently on our database later point of time. This is one of the feature present under SQL Workshop in Oracle Application Express.
