Simple Shell script
echo "Enter 1 for month of March"
echo "Enter 2 for month of April"
echo "Enter 3 for month of May"
read Month
case "$Month" in
1)
echo "enter establishment name"
read a;
mysql -u root -p $a < "March.sql";;
2)
echo "enter establishment name"
read b;
mysql -u root -p $b < "April.sql";;
3)
echo "enter establishment name"
read c;
mysql -u root -p $c < "May.sql";;
esac
done
In this i have three other query files March.sql, April.sql, May.sql. i'm linking this in shell script .
Example of .sql file:
SELECT DISTINCT substr(
a.case_no, 3, 2
), b.case_type, b.type_name, a.case_no into outfile '/tmp/April.csv'
FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n'
FROM Civil_t AS a, Case_type_t AS b, disposal_proc AS c
WHERE substr(
a.case_no, 3, 2
) = b.case_type
AND a.date_of_decision
BETWEEN '2014-04-01'
AND '2014-04-30'
AND a.case_no = c.case_no
AND a.court_no =1;
I have to alter the .sql script every time.
Is there any method to read the variables from shell script and use it in mysql. For example:-
echo "enter date"
read a #input date
Now i have read a "date" and i want to use it in March.sql query in where clause. Is there is any method of using this variable in .sql query.
