Passing a unix variable to sql query [message #140037]

Hi,
I am writing a function in unix which takes two parameters, say "param1" and "param2". This function consists of a simple sql query, say

function ABC(){
# assuming that connection to oracle went fine
# mentioning only the sql
SELECT * FROM TABLE123
WHERE C_DATE > SYSDATE - $param1
AND C_DATE < SYSDATE - $param2.
}
Can anyone help me out how to get it?

Thanks in advance....

Regards,
N.V Smile

Hi Naveen,
Place the sql in a file and invoke the sql file with command line parameters.

If you are using Oracle then you could easily use the command line sequential parameter feature like the &1, &2 etc.

An example:

----------------
sql file : test.sql
SELECT
A.ENAME,
A.ENO,
FROM EMP A,
WHERE E.ENO='&1';
quit;
-----------------
In the shell script invoke this sql file after logging into SQL*Plus client and redirect the output to a file.

sqlplus -S user/pass@sid @get_camps.sql $param1 > my_log.log

Hope this helps !

Best Regards,
Somnath
