I have these three Tables,
customers, cust_order, cust_debit
customers primary ID is added to cust_order and cust_order primary key is added to cust_debit.
I want records from customers and cust_order table on a condition which is associated to cust_debit. Tables Structure is as follow
cutomers cust_order cust_debit
cust_id fname, lname, ...... order_id, cust_id, order_date ID, order_id, amount
I need fname, lname, order_id, order_date from customers and cust_order where cust_debit.amount >=2000,
Now I need only one record of a particular customers.I used the following query
SELECT cust_order.order_id as order_id, customers.fname as fname , customers.lname as lname, cust_order.order_date as order_date,cust_order.order_status as order_status from cust_order,customers, cust_debit where customers.customer_id=cust_order.customer_id and cust_order.order_id = cust_debit.order_id and cust_debit.amount >=200
It works fine, But I need only one record of a customers, like when we use DISTINCT.
How can I use that.
Pls Help me
Thanks in Advance.

I'm not really sure what you are trying to acheive with the "cust_debit" table. It looks like it contains the amount outstanding for each order.
If it is the amount outstanding then the following change would give you the latest order for any customer who has a total of more than 2000 outstanding:
....
from (
select customer_id, max(order_id)
from cust_order
inner join cust_debit
on cust_debit.order_id = cust_order.order_id
group by customerId
having sum(cust_debit.amount) >= 2000
) as lastest_order_id
....The following uses a correlated-subquery to give you customers where any one single order has more than 2000 outstanding:
....
from (
select customer_id, max(order_id)
from cust_order
where 2000 <= (
select sum(cust_debit.amount) from cust_debit
where cust_debit.order_id = cust_order_id)
group by customerId
) as lastest_order_id
....Both examples give the details of the most-recent order. If you want the oldest order then use min(order_id). Hopefully you should now be able to solve your problem using one of these examples.

Dear there is a problem in ur query its not working correctly, infact system hangs when I execute ur query.
Pls help me. I m tied of this query.

Not half as tired as I am! I don't mind helping people, but it doesn't seem like you are trying very hard.
How about you putting some effort into understanding what the queries are trying to do. The SQL that I provided is basically three separate select-statements layered inside each other. I would suggest that you get the inner-most query working first:
select customer_id, max(order_id)
from cust_order
inner join cust_debit
on cust_debit.order_id = cust_order.order_id
group by customerId
having sum(cust_debit.amount) >= 2000 and the build up gradually to your final solution. If your machine is hanging then that may indicate that your database is not indexed properly.

Hi i have table like this format:
Id sMonth sYear value1
608 6 2007 100
608 7 2007 200
608 8 2007 150
608 6 2008 652
608 7 2008 120
608 8 2008 234
Suppose i need the records between the 6th month 2007 to 6th month 2008
O/P:
Id sMonth sYear value1
608 6 2007 100
608 7 2007 200
608 8 2007 150
608 6 2008 652
How to write the query???,
If its in date format we can use between condition...,
But in this case how u can compare the months and years ???,
Regards,
Magi

How about
select * from MyTable
where (sYear > 2007 or (sYear = 2007 and sMonth >= 6))
and (sYear < 2008 or (sYear = 2008 and sMonth <= 6)) or
select * from MyTable
where convert(varchar(6), (Year*100)+sMonth) between '200706' and '200806' Regards

Hi andy,
Thank u for ur reply...,
Ya i getting o/p for the first query...,
But second query is not giving proper o/p...,
Anyway one solution is enough...,
Thank's lot...,
keep in touch,
Regards,
Magi

|

You're welcome.
The second query should have used (sYear*100). I hadn't woken-up properly

5 votes to you man. I was about to say bad database design 
|
|
|
|
|
Sorry Magi,
Did not wanted to hurt your feelings about the design, But it is a bad practice, you should always use DateTime format. If you want to look at month and year only, you can still do that using datetime column. As you proceed further you will find data Access more and more difficult. That is why they say that make sure your design is right. Consult your senior developers about the design.
And finally, as you said, it might be right in your case, so thats good
Cheers

Actually, (Year*12)+sMonth wont get you those values at all

And looks like I wasn't reading properly either, before posting my message... pl ignore - I saw your clarification after I had hit the submit.
|

|

writing query for your requirement will be bit tough. Why don't you use date fields rather than storing date like this. In date fields you can use > or < operators to get the dates in between two dates.

Thanks for ur reply navaneeth...,
s navaneeth, i amn't getting date format from my end user...,
Just i am getting month and year only...,
So cant say in dateformat in my table...,
But any way thanks for ur suggestion...,
See andy's first query is giving solution for this probs...,
Keep in touch,
Friendly,

SELECT * FROM TblA
WHERE Convert(Datetime, '01/'+sMonth+'/'+sYear, 103) BETWEEN '01-Jun-2007' AND '30-Jun-2008'

You are right, the only thing is not all months have last day as 30, it can be 30, 28, 31... but well this is the right way to do anyway, there is a store procedure which gets the last day of the month in a particular year, can always use that.
|
|
|
|
|
given Month & Year are constant (june, 2007, 2008)
Also the date which is derived is always 1st.

Hi all
i have a case where i have 3 tables
table 1
blId blDesc
1 test1
----------
table 2
bl2Id bl2Desc blId
1 test2 1
-------------------
table 3
id name description
1 bilal test1.test2
the description of table3 (test1.test2) containing description from table1 and its child from table2
how can I query table3 and have instead of test1.test2, 1.1 (The Ids)
Please Help
|
|
|
|
|
For SQL-Server, you could try:
select table3.description,
convert(varchar, table1.blId) + '.' + convert(varchar, table2.bl2Id) as TheIds
from table3
inner join table1
on table3.description like table1.blDesc + '.%'
inner join table2
on table3.description like '%.' + table2.bl2Desc
order by table1.blId, table2.bl2IdRegards
Andy
