Hello and thank you for your time. I feel like this should be simple but I can’t seem to work it out….maybe I have been working on it so long that I need another perspective.
I have a Lab_result_obr_p table that contains labs that have been resulted: The PK is LabNum which is the lab Number and the FK is OrderNum which is the order number.
So in this table one order# can have multiple lab#s
Table: Lab_result_obr_p:
LabNum OrderNum
A29E02FED2C6DDA8
4A563D24D2C6DDA8
0F53BC60DC01E4EB
GS43A689DC01E4EB
F943C7034DF2654G7
The other table is Lab_rsults_obx and it contains the lab components and individual component results. In this table, each lab# (uique_obr_Number) from above will have multiple lab comments and results
Table: Lab_rsults_obx
LabNem LabC Flag Value
A29E02FEWBC N 3.5
A29E02FERBC N 260
4A563D24LMP: N 50
4A563D24RH TYPE N DNR
0F53BC60BACTERIA N TNP
GS43A689MCV N 30
GS43A689MCH N 40
F943C7034RH TYPE Y Negative
I need to select all ngn_order_num from Lab_result_obr_p where all components of all labs has a Abnormal_Flag of N and does not have a value of TNP. So if an Order has two labs, I need all the components for both labs to have an N for Abnormal_Flag and to not have a value of TNP for the order number to be selected
So for the data above my result would look like:
ngn_order_num
D2C6DDA8

Total guess but here is two ways that might work.
select *
from Lab_result_obr_p o
left join Lab_rsults_obx r on o.LabNum = r.LabNem and r.Flag = 'N' and Value <> 'TNP'
where re.LabNem is null
select *
from Lab_result_obr_p o
WHERE NOT EXISTS( SELECT 1 FROM Lab_rsults_obx r WHERE o.LabNum = r.LabNem and r.Flag = 'N' and Value <> 'TNP')
If you need more detailed help we will need a few things:
1. Sample DDL in the form of CREATE TABLE statements
2. Sample data in the form of INSERT INTO statements
3. Expected results based on the sample data
Please take a few minutes and read the first article in my signature for best practices when posting questions.

Thank you for your reply and I will read your article about posting
However, both examples fail to evaluate all records in the related table before returning the OrderNum
If an OrderNum has 2 #LabNum's each with 10 componets, I need all 10 components from both LabNum's to satisfy the conditions before returning the OrderNum. I have tried every exists combination that I know of but it never accounts for all components. I believe it grabs the first case that meets the condition instead of evaluating them all.
I will post the additional scripts you suggested soon
Thanks

Yeah those are the kinds of things that are hard to see when coding blind. 😉 Once you post some ddl and sample data we can knock this out.
You could possibly change the subquery in the exists version to something like this:
select top 1
FROM Lab_rsults_obx r
WHERE o.LabNum = r.LabNem
order by case when Flag = 'N' and Value <> 'TNP then 1 else 0 end

select distinct OrderNum as ngn_order_num
from Lab_result_obr_p o
join Lab_rsults_obx r on o.LabNum = r.LabNem and r.Flag = 'N' and Value <> 'TNP'
where OrderNum not in
(select distinct OrderNum as ngn_order_num
from Lab_result_obr_p o
join Lab_rsults_obx r on o.LabNum = r.LabNem and r.Flag = 'N' and Value = 'TNP')
-- OR depending on how you want to evaluate Value = 'TNP'
select distinct OrderNum as ngn_order_num

Seeing as I work in medical these tables look a lot like NextGen tables 😉

Ha....got to love NextGen!!

Thanks for all the help!
Edit....Out of all the offerings, this one seemed to work the best when testing

);
INSERT@Orders

chrissorric (7/17/2013)Thanks for all the help!
This is what I finally came up with
SELECTp.OrderNum
FROM@Orders AS p
INNER JOIN@Results AS x ON x.LabNum = p.LabNum
GROUP BYp.OrderNum
HAVING SUM(Case when x.Flag = 'N'THEN 1 ELSE 0 END)= COUNT (x.Flag) and
Max(CASE WHEN x.Value = 'TNP' THEN 1 ELSE 0 END) = 0
Interesting ... that is exactly the HAVING logic that I posted on the "SQL Team Forum" site in response to requestor "csorric". But I'm glad "you finally came up with" something that worked well for you.

I have corrected my English above Sir.
My Script has your name and Link to the post in the documentation. I posted here so that somebody else could find the answer if they needed. I appreciate your help and will be much more cognizant of documenting credit

A simple join seems to do the trick as well. It seems that I get TWO orders that meet the required condition though. Maybe you are just looking for the TOP(1)?
SELECT DISTINCT
p.OrderNum
--,r.LabNum
--,r.Lab_C
--,r.Flag
--,r.Value
FROM
@Orders AS p
INNER JOIN
@Results AS r
ON p.LabNum = r.LabNum
WHERE
r.Flag = 'N'
AND r.Value <> 'TNP'

Dunno much about NextGen but "OBR" and "OBX" are sure indicators that HL7 is involved 🙂

SELECT DISTINCT
p.OrderNum
--,r.LabNum
--,r.Lab_C
--,r.Flag
--,r.Value
FROM
@Orders AS p
INNER JOIN
@Results AS r
ON p.LabNum = r.LabNum
WHERE
r.Flag = 'N'
AND r.Value <> 'TNP'
I orginally created a report using just this simple join. But when I was testing the data, it doesn't account for orders having mulitple labs. ORder# DC01E4EB has two Labs ('0F53BC60','GS43A689'). Lab # GS43A689 has two componets (Lab_C) both of which pass the conditions, but Lab #0F53BC60 has one componet and it contains 'TNP' and does not meet both the conditions. The only Order that meets all conditions is 'D2C6DDA8'
