I have 3 tables:
'CouponType' table:
AutoID Code Name
1 CouT001 SunCoupon
2 CouT002 GdFriCoupon
3 CouT003 1for1Coupon
'CouponIssued' table:
AutoID CouponNo CouponType_AutoID
1 Co001 1
2 Co002 1
3 Co003 1
4 Co004 2
5 Co005 2
6 Co006 2
'CouponUsed' table:
AutoID Coupon_AutoID
1 2
2 3
3 5
I am trying to join 3 tables together using this query below but apparently I am not getting right values for CouponIssued column:
select CouponType.AutoID, Code, Name, Count(CouponIssued.CouponType_AutoID), count(CouponUsed.Coupon_AutoID)
from (CouponType left join CouponIssued
on (CouponType.AutoID = CouponIssued.CouponType_AutoID))
left join CouponUsed
on (couponUsed.Coupon_AutoID = CouponIssued.AutoID)
group by CouponType.AutoID, code, name
order by code
The expected result should be like:
**Auto ID Code Name Issued used**
1 CouT001 SunCoupon 3 2
2 CouT002 GdFriCoupon 3 1
3 CouT003 1for1Coupon 0 0
Thanks!
SELECT t.AutoID
,t.Code
,t.Name
,count(i.CouponType_AutoID) AS issued
,count(u.Coupon_AutoID) AS used
FROM CouponType t
LEFT JOIN CouponIssued i ON i.CouponType_AutoID = t.AutoID
LEFT JOIN CouponUsed u ON u.Coupon_AutoID = i.AutoID
GROUP BY 1,2,3;
You might consider using less confusing names for your table columns. I have made very good experiences with using the same name for the same data across tables (as far as sensible).
In your example, AutoID is used for three different columns, two of which appear a second time in another table under a different name. This would still make sense if Coupon_AutoID was named CouponIssued_AutoID instead.
change count(Coupon.CouponType_AutoID) to count(CouponIssued.CouponType_AutoID) and count(Coupon.Coupon_AutoID) to count(CouponUsed.Coupon_AutoID)

I'm having two tables (relation between themTest_case.id = Test_tag.test_id) like this:
Test_case table
id
name
1
Test name 1
2
Test name 2
3
Test name 3
4
Test name 4
Test_tag table
test_id
tag
1
feature:example1
1
package:Reports
1
QA
2
feature:example1
2
package:Reports
2
QA
3
feature:example1
3
package:Reports
3
QA
4
feature:newexample1
4
package:Charts
4
QA
The database tables and structure were already defined as I'm using a oublic library to push the results.
So, I need to return in the result the count of the id's and the value feature:example1
knowing that is a test that contains the tag package:Reports
So, it should return something like
Results
count(id)
tag
3
feature:example1
I already tried some different approaches without success.
How can I do that?
I think I'm as confused as everyone else, but this is a shot in the dark based on the various comments. There are much easier ways to arrive at this dataset, but I'm trying to read between the lines on your comments:
select
count (t.test_id), t.tag
from
test_case c
join test_tag t on c.id = t.test_id
where
t.tag like 'feature%' and
exists (
select null
from test_tag t2
where t2.test_id = t.test_id and t2.tag = 'package:Reports'
)
group by
t.tag
This is a modification to a previous question original answer , I hope the proper thing to do is start a new thread.
I have a table called Parts, PartRefID is the PK
PartRefID PartDefID AssemblyID
1 2 c63df10b-8250-4aa5-9889-9e8046331dbf
11 1 db51f4a8-3ffa-41f7-81c1-a9accbbb299a
67 6 136fc5d8-7b65-41b5-bca3-7d4180a1e0ab
77 5 38fa8b7a-2945-4546-8eab-7865a1e515b2
133 2 c63df10b-8250-4aa5-9889-9e8046331dbf
134 6 136fc5d8-7b65-41b5-bca3-7d4180a1e0ab
I need to extract rows with a unique AssemblyID. This was answered by GMB with the following sql:
select *
from parts as p
where [PartRefID] = (
select max(p1.[PartRefID])
from parts as p1
where p1.[AssemblyID] = p.[AssemblyID] and p1.[PartDefID] = 2
)
which worked beautifully. However requirements have changed and I must ignore the PartDefID field and there could also be AssemblyID's which represent parts I do not want.
The AssemblyID's shown in the above table represent an electrical connector part.
Electrical connector parts will ALWAYS have a Partclass of 1 which is defined in another table called PartDefinitions shown here:
PartDefID PartClass PartNumber
1 1 MS27467T23F55P
2 1 330-00186-09
3 2 336-00024-00
4 2 336-00022-00
5 1 MS27468T23F55S
6 1 330-00184-09
with my limited sql knowledge I decided a join was necessary and came up with the following code:
SELECT Parts.*, PartDefinitions.PartClass
From PartDefinitions
INNER Join Parts
On PartDefinitions.PartDefID = Parts.PartDefID
Where (((PartDefinitions.PartClass) = 1))
this gets me close, it produces all the parts in the parts table which are connectors. However there are some duplicate AssemblyID's.
what I need is to produce the following:
PartRefID PartDefID AssemblyID
1 2 c63df10b-8250-4aa5-9889-9e8046331dbf
11 1 db51f4a8-3ffa-41f7-81c1-a9accbbb299a
67 6 136fc5d8-7b65-41b5-bca3-7d4180a1e0ab
77 5 38fa8b7a-2945-4546-8eab-7865a1e515b2
my apologies if I have not made a clear and concise question
thanks for any help
and thanks again GMB
If I understand correctly, you want to filter by the PartClassId in both the subquery and the outer query:
select p.*, pd.PartClass
From Parts as p inner join
PartDefinitions as pd
on pd.PartDefID = p.PartDefID
where pd.PartClassId = 1 and
p.pPartRefID = (select max(p2.pPartRefID)
from parts as p2 inner join
PartDefinitions as pd2
on pd2.PartDefID = pd.PartDefID
where p2.AssemblyID = p.AssemblyID and
p2.PartClassId = 1
)
I want to show the combinations of "offers" that have the same number of "bids". The Both "OID" of the combination and the number of "bids" should be output.
I know the logic I want to show which article has the same bids in combination of other article, but I don't know how I can write it down. Some code can help me to understand this.
More information about the structure of the tables "offer" and "bid". Also a "Expected result" which is shown the result
I really want to learn SQL.
Try running this..
SELECT temp1.OID as OID1,temp2.OID as OID2,temp1.count1 as numberOfBids
FROM
(SELECT t1.OID,COUNT(t1.BID) as count1
FROM bid t1 group by t1.OID) temp1
JOIN
(SELECT t2.OID,COUNT(t2.BID) as count2
FROM bid t2 group by t2.OID) temp2
ON temp1.count1= temp2.count2
AND temp1.OID <> temp2.OID
But it will give output as below table
OID1 OID2 numberOfBids
1 2 2
1 5 2
2 5 2
5 1 2
5 2 2
I have below given query which is working fine but I want to use "Not In" operator instead of "In" but its giving no results:
SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails
WHERE (((OrderProdDetails.Priority) In (SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails WHERE (((OrderProdDetails.OrdID)=[Forms]![UpdateOrder]![OdrID])))));
Desired Query:
SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails
WHERE (((OrderProdDetails.Priority) Not In (SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails WHERE (((OrderProdDetails.OrdID)=[Forms]![UpdateOrder]![OdrID])))));
Basically it is referencing a control on parent form and based on that in a subform I want to populate the priority numbers i.e 1,2,3 and if for that record 1 is entered I want to get only 2 and 3 as drop-down option.
ReocordID OrdID Brand Name Priority
2 1 Org 1 2
3 2 Org 2 1
4 1 Org 1 1
6 1 Org 1 3
7 3 Org 3 1
8 4 Org 1 1
9 5 Org 2 1
10 5 Org 2 2
11 6 Org 1 1
12 6 Org 2 2
If there is any other better approach for the same please suggest.
Thanks in advance for your help.
In all likelihood, your problem is that Priority can take on NULL values. In that case, NOT IN doesn't work as expected (although it does work technically). The usual advice is to always use NOT EXISTS with subqueries rather than NOT IN.
But, in your case, I would suggest conditional aggregation instead:
SELECT opd.Priority
FROM OrderProdDetails as opd
GROUP BY opd.Priority
HAVING SUM(IIF(opd.OrdID = [Forms]![UpdateOrder]![OdrID], 1, 0)) = 0;
The HAVING clause counts the number of times the forms OdrId is in the orders. The = 0 means it is never there. Plus, you no longer need a select distinct.
Thanks for your prompt answers however I figured out what the problem was and the answer to problem is.
SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails
WHERE (((OrderProdDetails.Priority) Not In (SELECT OrderProdDetails.Priority
FROM OrderProdDetails WHERE (((OrderProdDetails.OrdID)=[Forms]![UpdateOrder]![OdrID])
and ((OrderProdDetails.Priority) Is not null) ))));
I realized that the problem was happening only to those where there was a null value in priority so I puth the check of not null and it worked fine.
Thanks
I am a long time fan of Stack Overflow but I've come across a problem that I haven't found addressed yet and need some expert help.
I have a query that is sorted chronologically with a date-time compound key (unique, never deleted) and several pieces of data. What I want to know is if there is a way to find the start (or end) of a region where a value changes? I.E.
DateTime someVal1 someVal2 someVal3 target
1 3 4 A
1 2 4 A
1 3 4 A
1 2 4 B
1 2 5 B
1 2 5 A
and my query returns rows 1, 4 and 6. It finds the change in col 5 from A to B and then from B back to A? I have tried the find duplicates method and using min and max in the totals property however it gives me the first and last overall instead of the local max and min? Any similar problems?
I didn't see any purpose for the someVal1, someVal2, and someVal3 fields, so I left them out. I used an autonumber as the primary key instead of your date/time field; but this approach should also work with your date/time primary key. This is the data in my version of your table.
pkey_field target
1 A
2 A
3 A
4 B
5 B
6 A
I used a correlated subquery to find the previous pkey_field value for each row.
SELECT
m.pkey_field,
m.target,
(SELECT Max(pkey_field)
FROM YourTable
WHERE pkey_field < m.pkey_field)
AS prev_pkey_field
FROM YourTable AS m;
Then put that in a subquery which I joined to another copy of the base table.
SELECT
sub.pkey_field,
sub.target,
sub.prev_pkey_field,
prev.target AS prev_target
FROM
(SELECT
m.pkey_field,
m.target,
(SELECT Max(pkey_field)
FROM YourTable
WHERE pkey_field < m.pkey_field)
AS prev_pkey_field
FROM YourTable AS m) AS sub
LEFT JOIN YourTable AS prev
ON sub.prev_pkey_field = prev.pkey_field
WHERE
sub.prev_pkey_field Is Null
OR prev.target <> sub.target;
This is the output from that final query.
pkey_field target prev_pkey_field prev_target
1 A
4 B 3 A
6 A 5 B
Here is a first attempt,
SELECT t1.Row, t1.target
FROM t1 WHERE (((t1.target)<>NZ((SELECT TOP 1 t2.target FROM t1 AS t2 WHERE t2.DateTimeId<t1.DateTimeId ORDER BY t2.DateTimeId DESC),"X")));
