Need help with script

Question

There is request to dump every day’s data from one table into text file. I need to write shell script and sql script for that
There are two tables (INSPECTION_RESULTS and NJAS) under NJSHDOWN schema. The table NJAS is child table of INSPECTION_RESULTS. The key is RES_SYS_NO. The script should get the MIN and MAX RES_SYS_NO from INSPECTION_RESULTS table for yesterday’s date. Then use these RES_SYS_NOs to fetch data from NJAS table. I then need to create comma delimited file for following columns. Also, to add the logic in shell script to check for oracle error (ORA-). If there is error, it should send email to DBAs group(first test it with your email address).
Following columns are needed from NJAS table.
NJA_RES_SYS_NO
NJA_TEST_REC_NO
NJA_LIC_ST_ID
NJA_ETS_ID
NJA_SW_VER
NJA_TECH_ID
NJA_VIN
NJA_LIC_NO
NJA_LIC_JUR
NJA_LIC_SRC
NJA_MODEL_YR
NJA_MAKE
NJA_MODEL
NJA_VHCL_TYPE
NJA_BODY_STYLE
NJA_CERT_CLASS
NJA_GVWR
Okay- here is the script that I have so far but now, I am stuck. I cannot figure out how to get my script to finish output to comma delimited file and to check for oracle errors. Can anyone help me out here? Thanks!

SELECT NJA_RES_SYS_NO, NJA_RES_SYS_NO, NJA_TEST_REC_NO,

FROM NJAS
WHERE NJA_RES_SYS_NO IN (SELECT MIN(NJA_RES_SYS_NO) FROM INSPECTION_RESULTS WHERE NJA_RES_SYS_NO IN
(SELECT MAX(NJA_RES_SYS_NO) FROM INSPECTION_RESULTS WHERE SYSDATE=SYSDATE-1)
Thanks!

Thanks here is thus far what I have, focusing on the sql script part which is the trickiest:
-- writedate.sql script for njas

How do I strip the comments from the output file? Also not sure if my subquery is performing the output correctly. Thanks.
