Shell script to call sql file

Shell Programming and Scripting
1

hi ,

the below script contains sql query and after executed it sends the output of the query (output.txt) to an email body with conditional subject line based on the output of all_counts_match.txt.

i want to make this script generic so that it can accept the sql file as parameter and can be reuse for any other sql query and generates the output in a same way as it does..the problem is there are two sql queries so how to achive this?

thanks in advance..

sqlplus -s abc/yahoo@xe <<EOF
set feedback off trimspool on
set linesize 4000
set newpage 0
set pagesize 0
set wrap on
set echo off
set verify off
SET COLSEP "|"
alter session enable parallel dml;
spool output.txt
SELECT PROCESS_DATE  ,table_name ,
(CASE WHEN table_row_count = input_record_cnt THEN 'Yes' ELSE 'No' END) COUNTS_MATCHING
FROM t1
WHERE insert_date = TRUNC(SYSDATE);
spool off
spool all_counts_match.txt
select case when sum(case when table_row_count = input_record_cnt then 1 else 0 end) = count(*)
then 1 else 0
end as x
from t1
where insert_date = trunc(sysdate);
spool off
exit
EOF

if [[ $(cat all_counts_match.txt) -eq 1 ]]; then
<output.txt mail -s "load counts Match for  $(date '+%C%y%m%d')" sk@xyz.com
else
<output.txt mail -s "WARNING- load counts do not match for $(date '+%C%y%m%d')" sk@xyz.com
fi
rm -f output.txt
rm -f all_counts_match.txt

Without digging deeper into this - some ideas (untested; no guarantee they will work):

  • source a respective sql text file
  • have a case statement with the different sql queries
  • assign the sql queries to several variables and have those expanded in the here document

Give any of these a try and come back with the results.

You can't dump sql code in shell and expect it to go into your database. The shell is trying to process it as shell code and not understanding it.

To feed it into sqlplus, tell the shell to feed it into sqlplus, like so:

sqlplus sqlparameters <<EOF
text
text
text
EOF

The ending EOF cannot be indented, at all.

sorry i am not able to get your point..
i want to use this sql query inside the script ...pls let me know how can i do this..

select case when sum(case when table_row_count = input_record_cnt then 1 else 0 end) = count(*)
then 1 else 0
end as x
from t1
where insert_date = trunc(sysdate);

replace 'text' with your query.
