Implement a SQL query in Crystal reports - sql

Question

I want to generate a report in Crystal Reports and I am very new to it. I am unaware of how to manipulate the Crystal Report. I made a SQL query which gives me all the required output from the Oracle(10g) database. But I need to convert it to be used inside Crystal Reports.
This is the SQL query which gives me required output:
SELECT
ins.ins_name,ins.ins,crdi.ct, crdi.bn,
sum(DECODE(cardh.crd_st, 'PO', 1, 0)) POCount,
sum(DECODE(cardh.crd_st, 'CN', 1, 0)) CNCount
FROM
crdh, crdi, ins
WHERE
crdh.crd_st IN ('PO','CN')
and crdi.bn in (select unique bn from crdh)
and crdh.bn = crdi.bn
and crdi.ins = ins.ins
GROUP BY
ins.ins, crdi.bn, ins.ins_name, crdi.ct
ORDER BY
ins.ins, crdi.bn;
When I implemented the above query I got the following error:
a) When I put the above query in Database|Show SQL Query..., the following part of the query is removed:
sum(DECODE(cardh.crd_st, 'PO', 1, 0)) POCount,
sum(DECODE(cardh.crd_st, 'CN', 1, 0)) CNCount
GROUP BY ins.ins, crdi.bn, ins.ins_name,crdi.ct
b) When I added a group for ins.ins, Crystal reports adds a lots of spaces in the report.
c) How can I print the value of POCount and CNCount in the crystal report?
I am also adding the screenshot of the output for better understanding.
There can be multiple BN for one INS and for one BN there are multiple CNs and POs. Like INS 3 has two BN ('123456','789012') and there are 3 POs and 0 CN in BN '123456', but there is only one CN in BN '789012'. I hope this is helpful to replier.
Please help me to get a report same as the output of the above mentioned query. Thanks in advance.
I got the following result :

Dont implement sum in query instead implement it in crystal. so change the query like this.
SELECT ins.ins_name,ins.ins,crdi.ct, crdi.bn,
cardh.crd_st,cardh.crd_st
FROM crdh, crdi, ins
Add above query in crystal report command when you make a connection to the report.
Now for your report to display in the required format.
Create a formula #PO
if cardh.crd_st= 'PO'
then 1
else 0
Create formula for CN
if cardh.crd_st='CN'
then 1
else 0
Place above formula in detail
Create a group by ins.ins_name
Place all your columns in group footer and at the same time take sum for the formulas #po and CN
As you are using where condition in query to get that condition in CR. Implement your where clause in Select Expert ---> Record Selection Formula, If you are not comfortable then try implement the where clause in query itself.
Let me know how it goes.
