I have a large raw data table. It's long and I'm trying to sort of transpose it. I'm joining two select statements from within it. As such I get multiple columns with the same name. It's a full outer join and I would like to have the two separate columns of the same name as one column. Since it is an outer join I don't want to pick just one tables column for it either like select t1.c1
Thanks!
SELECT *
FROM (SELECT * FROM [LabData].[dbo].[FermHourlyDCSData] where Attribute='Urea') P
full outer JOIN
(SELECT * FROM [LabData].[dbo].[FermHourlyDCSData] where Attribute='Water to Mash Total Water') FPD ON
P.[TimeStamp] = FPD.[TimeStamp]
and P.Site = FPD.Site
and P.Element = FPD.Element
Actual:
Site Attribute Timestamp Value Site Attribute Timestamp Value
AD Urea 1/1/2019 127 Null Null Null Null
Null Null Null Null AD Water 1/1/2019 7.5
Expected/Desired:
Site Attribute Timestamp Value Value
AD Urea 1/1/2019 127 Null
AD Water 1/1/2019 Null 7.5
Try this, it's not very pretty, but it does work:
SELECT
[Site] = ISNULL(P.[Site], FPD.[Site]),
[Attribute] = ISNULL(P.[Attribute], FPD.[Attribute]),
[Timestamp] = ISNULL(P.[Timestamp], FPD.[Timestamp]),
[Value] = ISNULL(P.[Value], FPD.[Value]),
[Element] =ISNULL(P.[Element], FPD.[Element])
FROM (SELECT * FROM [dbo].[FermHourlyDCSData] where Attribute='Urea') P
full outer JOIN
(SELECT * FROM [dbo].[FermHourlyDCSData] where Attribute='Water to Mash Total Water') FPD ON
P.[TimeStamp] = FPD.[TimeStamp]
and P.Site = FPD.Site
and P.Element = FPD.Element
ISNULL is what you should use for this
ISNULL(p.Site,fpd.Site) as [Site]
Maybe I'm missing something, but you seem to want a much simpler query:
select Site, Attribute, Timestamp,
(case when Attribute = 'Urea' then Value end) as value_u,
(case when Attribute = 'Water to Mash Total Water' then Value end) as value_2
from [LabData].[dbo].[FermHourlyDCSData]
where Attribute in ('Urea', 'Water to Mash Total Water')

I'm working on generating a report merging multiple tables. The report requires only showing projects that did not have any document marked 'Not Received' These document markings are listed in a table that lists each document in an individual line. So when merged into my other table it creates multiple rows of the same project. For example the following table
Project Number
ChecklistValue
565
Received
565
Not Received
465
Received
465
Not Applicable
As you can see really only two projects are listed on this table but the desired output is:
Project Number
Other Info
465
etc
I do not need the checklist value on the actual report, so I can use the GROUP BY to combine all the good rows, but where I have an Issue is that would still include project 565 even if I include something like where ChecklistValue <> 'Not Received', 565 needs to be hidden from the report entirely because any row for 565 contains 'Not Received'.
So that's my actual question, how do I exclude all project numbers rows that have any row containing 'Not Received'?
I'm adding the entire query will generalized names below:
SELECT
Project Number
,Name
,Contractor
,ABS(DATEDIFF(day,(ActualDate),(EstDate))) AS DelayPeriod
,S.NoteDate
,S.FinalAppDate
,Status
,S.ONE
,S.TWO
,S.THREE
,S.FOUR
,CH.ChecklistValue
FROM [DB1] A
INNER JOIN [DB2] C ON A.Contractor = C.Contractor
INNER JOIN [DB3] S ON A.AppID = S.AppID
INNER JOIN [DB4] LS ON S.StatusID = LS.StatusID
LEFT OUTER JOIN [DB5] CH ON A.AppID = CH.AppID AND CH.OtherID = 1
WHERE C.TypeID = 4 AND A.YEAR = 2022, AND S.THING = 1 AND
(CH.CheckListValue IS NULL OR A.AppID NOT IN (SELECT * FROM [DB5] WHERE
CheckListValue = 'Not Reveived'))
GROUP BY Project Number,Name,Contractor,ABS(DATEDIFF(day,(ActualDate),(EstDate))) AS DelayPeriod,S.NoteDate,S.FinalAppDate,Status,S.ONE,S.TWO,S.THREE,S.FOUR
The last portion of the WHERE clause was added from a suggestion, but I'm clearly not implementing it correctly as it errors
You can use not in like:
create table test(
num int,
description varchar(20)
);
insert into test(num,description)
values(565,'Received'),
(565,'Not Received'),
(465,'Received'),
(465,'Not Applicable');
select *
from test
where num not in
(
select num -- Only select one column here
from test
where description = 'Not Received'
);
Results:
+-----+---------------+
| num | description |
+-----+---------------+
| 465 | Received |
| 465 | Not Applicable|
+-----+---------------+
db<>fiddle this is on sql-server but works on other dbms as well.
So in your query you should have (in my understanding):
OR A.AppID NOT IN
(
SELECT AppID -- Not select *
FROM [DB5]
WHERE CheckListValue = 'Not Reveived'
)
Other way to do it is with a cte but it is complicated at first glance:
with x as(
select num
from test
where description = 'Not Received'
)
select t.num, t.description
from test t
left join x
on t.num = x.num
where x.num is null
I'm first creating a cte on the num column where the description = not received then I'm selecting all from the test table, and I'm left joining to the cte but I'm only selecting the num column that are not in the cte by using where x.num is null, and this will only return 465.
Now which one is better? I don't know sometimes join would be faster and sometimes in, for more you can find on this post.
I have tables:
Result containing 5 columns: result_id, num_1, num_2, num_3, num_4
Ref containing 4 columns: num_1, num_2, num_3, num_4
Columns num contain random int in range of 1-9
Aim of exercise is to display all result_id from Result table which have num values combination present in Ref table and to display result_id which have not met combination criteria.
I've been trying left joining ref to result, but unfortunately no success. Could you please share some light how to deal with it?
If you want the result_id for which combination exists in the ref table then use following JOIN query:
select distinct r.result_id
from results r
join ref on r.num_1 = ref.num_1 and r.num_2 = ref.num_2
and r.num_3 = ref.num_3 and r.num_4 = ref.num_4
If you want the result_id for which combination do not exists in REF table then use the LEFT JOIN as follows:
select r.result_id
from results r
left join ref on r.num_1 = ref.num_1 and r.num_2 = ref.num_2
and r.num_3 = ref.num_3 and r.num_4 = ref.num_4
where ref.num_1 is null -- or use PK / Not nullable column of REF table here
Assuming you want the columns to "line up" and you want to add a flag to the result_id in the first table, then use exists:
select t1.*,
(case when exists (select 1
from table2 t2
where t2.n1 = t1.n1 and t2.n2 = t1.n2 and t2.n3 = t1.n3 and t2.n4
)
then 'present' else 'not present'
end) as flag
from t2;
I have two table named Soft and Web, table containing multiple data in that which data is different that data I want. For Ex :
In soft table containing 5 data i.e.
Also in Web table containing 5 data i.e.
Now I want output i.e.
I have done query but unfortunately didnt succed, lets see my query i.e.
SELECT DISTINCT soft.GSTNo AS SoftGST
,web.GSTNo AS WebGST
,soft.InvoiceNumber AS SoftInvoice
,web.InvoiceNumber AS WebInvoice
,soft.Rate AS SoftRate
,web.Rate AS WebRate
FROM soft
LEFT OUTER JOIN web ON web.GstNo = soft.GSTNo
AND web.InvoiceNumber = soft.invoicenumber
AND web.rate = soft.rate
Also I apply inner join bt same thing didnt work.
You can achieve this by
;WITH cte_soft AS
(SELECT * FROM soft
EXCEPT
SELECT * FROM web)
,cte_web AS
(SELECT * FROM web
EXCEPT
SELECT * FROM soft)
SELECT *
FROM
(SELECT gst softgst, NULL webgst, invoice softinvoice, NULL webinvoice, rate softrate, NULL webrate
FROM cte_soft
UNION ALL
SELECT NULL, gst, NULL, invoice, NULL , rate
FROM cte_web) tbl
ORDER BY coalesce(softgst, webgst),coalesce(softinvoice,webinvoice)
Fiddle
You can use full join:
SELECT s.gst as softgst, w.gst as webgst,
s.invoice as softinvoice, w.invoice as webinvoice,
s.rate as softrate, w.rate as webrate
FROM soft s FULL JOIN
web w
ON s.gst = w.gst AND s.invoice = w.invoice AND s.rate = w.rate
WHERE s.gst IS NULL OR w.gst IS NULL
ORDER BY COALESCE(s.gst, w.gst), COALESCE(s.invoice, w.invoice);
No subqueries are CTEs are needed. This is really just a slight variant of your query.
Backstory:
I have three tables I'm working with. A directory table (directory), an general attribute table (attribute1table) and a specific attribute table (attribute2table). The general attribute tables hold attribute names (ex. Last Name) under attribute id's (attrid = 2). The specific attribute table holds specific data for these attributes (ex. Doe).
I needed to transpose rows to columns. I had tried using pivot, and max(decode) before but all options gave me the wrong string value- so I used a sub select within the select statement. This worked well- it did transpose the rows into columns but gave me a bunch of null values. See query at the bottom for steps.
Then I added in a general 'stringval IS NOT NULL' to eliminate any of the other attribute1table.attrid's (ex. 4, 5, 6). This worked.
This is the output I was getting at this point. The ? are null values.
Name DataID LastName FirstName
File10 1290 ? Jane
File10 1290 Doe ?
Then I wanted to add in a specification. Essentially to include the values where LastName is not null OR FirstName is not null. I found that someone had recommended doing this in a previous question albeit their situation was different. Eliminating specific null values in sql select
I was able to include one statement or the other but could not add in both. Instead of getting an error I just got a horrifically long run time with no foreseeable result (note that I am using software which lets you input oracle queries within the interface to query the database). It works if I run the query up until the ** (see code) but as soon as I add in the OR condition, it doesn't work anymore. I think this is because I have multiple WHERE conditions. In all cases I want the directory ID and general stringval conditions to apply but I want to have a third condition where either lastname is not null or first name is not null. I'm not sure if I'm missing something obvious- please help?
Here is my current query:
SELECT directory.name, directory.dataid,
(SELECT max(stringval) FROM attribute2table WHERE attribute1table.attrid = 2) as LastName,
(SELECT max(stringval) FROM attribute2table WHERE attribute1table.attrid = 3) as FirstName
FROM attribute2table
JOIN directory ON directory.dataid = attribute2table.id
JOIN attribute1table ON attribute1table.id = directory.dataid
WHERE directory.dataid = 1290
AND stringval IS NOT NULL
AND (SELECT max(valstr) FROM attribute1table WHERE attribute1table.attrid = 2) IS NOT NULL
**OR (SELECT max(valstr) FROM attribute1table WHERE attribute1table.attrid = 3) IS NOT NULL**
Basically I just need to get rid of the null values and want my table to look like....
Name DataID LastName FirstName
File10 1290 Doe Jane
This appears to be a parenthesization issue. If I understand the issue, you need to put the two IS NOT NULL conditions in parentheses:
SELECT directory.name,
directory.dataid,
m2.LastName,
m3.FirstName
FROM attribute2table
INNER JOIN directory
ON directory.dataid = attribute2table.id
INNER JOIN attribute1table
ON attribute1table.id = directory.dataid
LEFT OUTER JOIN (SELECT max(valstr) AS LASTNAME
FROM attribute1table
WHERE attribute1table.attrid = 2) m2
ON 1 = 1
LEFT OUTER JOIN (SELECT max(valstr) AS FIRSTNAME
FROM attribute1table
WHERE attribute1table.attrid = 3) m3
ON 1 = 1
WHERE directory.dataid = 1290 AND
stringval IS NOT NULL AND
(m2.LASTNAME IS NOT NULL OR
m3.FIRSTNAME IS NOT NULL)
I also rewrote the query using joins instead of subselects as I think it's a bit clearer.
Note also that in the M2 and M3 joins I used LEFT OUTER with a condition of 1 = 1 rather than using CROSS JOIN, because I've noticed that CROSS JOIN acts like an INNER JOIN if the query being cross-joined returns no rows - that is, it causes the entire SELECT to return no data. dbfiddle demonstrating this situation here
I'm pretty sure you just need conditional aggregation:
SELECT d.name, d.dataid,
MAX(CASE WHEN a1.attrid = 2 THEN a2.stringval END) as LastName,
MAX(CASE WHEN a1.attrid = 3 THEN a2.stringval END) as FirstName
FROM directory d JOIN
attribute2table a2
ON a2.id = d.dataid JOIN
attribute1table a1
ON a1.id = d.dataid
WHERE d.dataid = 1290
GROUP BY d.name, d.dataid
I have this table:
Table_NAME_A:
quotid itration QStatus
--------------------------------
5329 1 Assigned
5329 2 Inreview
5329 3 sold
4329 1 sold
4329 2 sold
3214 1 assigned
3214 2 Inreview
Result output should look like this:
quotid itration QStatus
------------------------------
5329 3 sold
4329 2 sold
3214 2 Inreview
T-SQL query, so basically I want the data within "sold" status if not there then "inreview" if not there then "assigned" and also at the same time if "sold" or "inreview" or "assigned" has multiple iteration then i want the highest "iteration".
Please help me, thanks in advance :)
This is a prioritization query. One way to do this is with successive comparisons in a union all:
select a.*
from table_a a
where quote_status = 'sold'
union all
select a.*
from table_a a
where quote_status = 'Inreview' and
not exists (select 1 from table_a a2 where a2.quoteid = a.quoteid and a2.quotestatus = 'sold')
union all
select a.*
from table_a a
where quote_status = 'assigned' and
not exists (select 1
from table_a a2
where a2.quoteid = a.quoteid and a2.quotestatus in ('sold', 'Inreview')
);
For performance on a larger set of data, you would want an index on table_a(quoteid, quotestatus).
You want neither cursors nor if/then for this. Instead, you'll use a series of self-joins to get these results. I'll also use a CTE to simplify getting the max iteration at each step:
with StatusIterations As
(
SELECT quotID, MAX(itration) Iteration, QStatus
FROM table_NAME_A
GROUP BY quotID, QStats
)
select q.quotID, coalesce(sold.Iteration,rev.Iteration,asngd.Iteration) Iteration,
coalesce(sold.QStatus, rev.QStatus, asngd.QStatus) QStatus
from
--initial pass for list of quotes, to ensure every quote is included in the results
(select distinct quotID from table_NAME_A) q
--one additional pass for each possible status
left join StatusIterations sold on sold.quotID = q.quotID and sold.QStatus = 'sold'
left join StatusIterations rev on rev.quotID = q.quotID and rev.QStatus = 'Inreview'
left join StatusIterations asngd on asngd.quotID = q.quotID and asngd.QStatus = 'assigned'
If you have a table that equates a status with a numeric value, you can further improve on this:
Table: Status
QStatus Sequence
'Sold' 3
'Inreview' 2
'Assigned' 1
And the code becomes:
select t.quotID, MAX(t.itration) itration, t.QStatus
from
(
select t.quotID, MAX(s.Sequence) As Sequence
from table_NAME_A t
inner join Status s on s.QStatus = t.QStatus
group by t.quotID
) seq
inner join Status s on s.Sequence = seq.Sequence
inner join table_NAME_A t on t.quotID = seq.quotID and t.QStatus = s.QStatus
group by t.quoteID, t.QStatus
The above may look like complicated at first, but it can be faster and it will scale easily beyond three statuses without changing the code.
