Pro*C - PERCENT_RANK() compilation issue

Question

Hello,
I have a pro*C compilation issue, while using PERCENT_RANK() in-built function. I am using Oracle 10.2.0.4.
Here are the details :
The Pro*C code :
================================================== ========
int srccct2_insert()
EXEC SQL
select * from (
select
trad_code,
comp_code,
file_code,
insp_yymm,
poly_numb,
entr_numb,
data_code,
caus_date,
insd_code,
rule_ordr,
sex_code,
entr_age,
resd_numb,
entr_name,
hire_date,
entr_date,
work_year,
hire_grad,
datt_entr,
ijry_entr,
wkdt_entr,
base_saly,
expt_amnt,
rsrv_rato,
rsrv_amnt,
PERCENT_RANK() OVER (ORDER BY base_saly) pr FROM SRCCCT2 where trad_code = 'N' AND
comp_code = '01' AND
insp_yymm = '200403' AND
data_code = 'B' AND
hire_grad = '2' AND
base_saly > 0)
where pr > 0.05 and pr < 0.95 and base_saly > 641840;
return SUCCESS;
================================================== ======
I am compiling it like this :
/oracle/product/10.2.0/bin/proc iname=srascs01.pc ireclen=320 oreclen=320 sqlcheck=full userid=retr/rteru maxopencursors=32 dbms=v8 char_map=varchar2 release_cursor=yes include=/oracle/product/10.2.0/precomp/public include=/ihome/hp/../common/include include=/ihome/retr/include include=/usr/include include=/ihome/hp/portlib DEFINE=HPUX
I have put the same sql statements in the sql promt and it works fine. But in Pro*C when i compile it using above options, here is the error :
================================================== ======

After searching in this website, i saw a related thread. But that solution did not work for me. I have posted a reply on that aswell, for Mark_Williams. Here is the related link:

Hi Sumit,
Thanks much for a reply.
I am very novice for Pro*C. Please bear with me, if i sound odd anywhere.
I did check the program again. When i leave EXEC SQL and put the whole SELECT statement in double quotes and then postfix back slashes at each line in the SELECT statement, compilation succeeds. But I am just wondering, if this works fine, even if we don't use, "EXEC SQL" ?
When we use "EXEC SQL" and double quotes also, there seems to be two double quotes before SELECT and so compilation fails, with the below error msg. I think "EXEC SQL" is also appending a double quote.(??)
I did not really understand when you said "declaring the sql statement and calling EXEC SQL PREPARE". Are you talking about declaring the sql statement in sqlplus ?
If the above method of removing "EXEC SQL" and using double quotes and slashes is correct, then i think we anyway need not do anything else as the compilation went through.
Thanks again,
-Kumar
