Hello everyone,
I need some help with the SQL query posted below:
SET NOCOUNT ON
DECLARE cursor resolverate is
select hcfadrgcode, insplancode, sum(f.TOTALPAYMENTS)/sum(f.totalactualcharges) rr
from encounter e, encounterfinancialrecord f
where e.encounterid = f.encounterid
and e.encountertypecode = 'I'
and to_char(dischargetimestamp, 'YYYY-MM') >= '2004-01'
and to_char(dischargetimestamp, 'YYYY-MM') <= '2005-02'
and e.totalactualcharges > 0
and (arbal = 0 or bdind = 'Y')
group by hcfadrgcode, insplancode;
Open resolverate;
BEGIN
FOR test in resolverate
loop
select e.encounterid, (f.totalactualcharges * test.rr)
from encounter e, encounterfinancialrecord f
where e.encounterid = f.encounterid
and e.encountertypecode = 'I'
and e.hcfadrgcode = test.hcfadrgcode
and e.insplancode = test.insplancode;
end loop;
END;
/
When I run this code, I get several errors. And I don't even think if the syntax are correct or not. In my first cursor, I'm trying to get a rate based on hcfadrgcode and insplancode. And then I would like to assign that rate in my loop to all accounts that has same hcfadrgcode and insplancode. Please let me know if you need more information.
Thanks,

You can not use "select col1, col2 from" in a cursor program.
Declare variables before "BEGIN" and use "INTO" clause to select the data.
e.g. "select col1 into var_col1 from"
Hope it helps.

How would I do that using my code. I have never done cursor before and I'm bit confused about declaring variable before begin statement. Please guide me through my code.
Thank you so much

Try this.
set serveroutput on
DECLARE
cursor resolverate is
select hcfadrgcode, insplancode, sum(f.TOTALPAYMENTS)/sum(f.totalactualcharges) rr
from encounter e, encounterfinancialrecord f
where e.encounterid = f.encounterid
and e.encountertypecode = 'I'
and to_char(dischargetimestamp, 'YYYY-MM') >= '2004-01'
and to_char(dischargetimestamp, 'YYYY-MM') <= '2005-02'
and e.totalactualcharges > 0
and (arbal = 0 or bdind = 'Y')
group by hcfadrgcode, insplancode;
var1 number;
var2 number;
BEGIN
FOR test in resolverate
loop
select e.encounterid, (f.totalactualcharges * test.rr) into var1, var2
from encounter e, encounterfinancialrecord f
where e.encounterid = f.encounterid
and e.encountertypecode = 'I'
and e.hcfadrgcode = test.hcfadrgcode
and e.insplancode = test.insplancode;
dbms_output.put_line(var1||' '||var2);
end loop;
END;
/
Make sure following query works on sqlplus if you get error.
select hcfadrgcode, insplancode, sum(f.TOTALPAYMENTS)/sum(f.totalactualcharges) rr
from encounter e, encounterfinancialrecord f
where e.encounterid = f.encounterid
and e.encountertypecode = 'I'
and to_char(dischargetimestamp, 'YYYY-MM') >= '2004-01'
and to_char(dischargetimestamp, 'YYYY-MM') <= '2005-02'
and e.totalactualcharges > 0
and (arbal = 0 or bdind = 'Y')
group by hcfadrgcode, insplancode;
Hope it helps.
