I have to connect accounts to users, and in doing so I have ensure I'm selecting the right account to ensure eligibility and do this with multiple accounts. The following code passes validation but yields no results.
I already have a list of the CustomerNumbers on the table that are the PK.
SELECT
x.CustomerNumber,
a.ACC_AccountId
FROM Eligibles x
LEFT JOIN
ACCOUNTS a
ON x.CustomerNumber = a.ACC_CustomerNumber
ORDER BY a.ACC_LIVEcode ASC,
a.ACC_Limit DESC,
a.ACC_Amount DESC
OFFSET 0 ROWS
FETCH FIRST 1 ROWS ONLY
I am not getting any Account ID's to populate, whereas nearly everyone should have one.
In an ascending sort, NULLs are first. So, you get the mismatches first. Instead, add an expression so the matches are first:
SELECT x.CustomerNumber, a.ACC_AccountId
FROM Eligibles x LEFT JOIN
ACCOUNTS a
ON x.CustomerNumber = a.ACC_CustomerNumber
ORDER BY (CASE WHEN ACC_CustomerNumber IS NOT NULL THEN 1 ELSE 0 END),
aa.ACC_LIVEcode ASC, a.ACC_Limit DESC, a.ACC_Amount DESC
OFFSET 0 ROWS
FETCH FIRST 1 ROWS ONLY

I am attempting to filter my table and get the item that sold for the most amount of money. In order to do this I am using "AuctionOpen" to determine whether or not the auction is still open. The auction cannot be open and have the item been sold (later I will use this for the most expensive item available).
I am able to use the AND operator to compare AuctionOpen by using the following:
select s.*
from auctionsite.dbo.Auction s
where s.HighestBid = (select max(s2.HighestBid) from auctionsite.dbo.Auction
s2) and s.AuctionOpen = 0;
When I set this equal to zero I get results, but when I set it equal to 1, it only returns the column titles even though there are values set to 1 in the table.
Results when compared to 0:
Results when compared to 1:
Clearly, the highest bid is on a record where AuctionOpen <> 1.
I recommend using order by and fetch (or the equivalent in your database):
select s.*
from auctionsite.dbo.Auction s
where s.AuctionOpen = 0
order by s.HIghestBid desc
fetch first 1 row only
In SQL Server, use either select top (1) or offset 0 rows fetch first 1 row only.
I think you should try the Count aggregate function
here, try this:
**Select count(Item_name) As
[Item with the highest money]
from table_name
Group by Item_name DSEC;**

I have a small piece of data (15 records) where part of it I want ordered in alphabetical order, and part of it ordered by ID
Image 1 shows my data in the original order
After doing the query SELECT * FROM tableName ORDER BY code;
Image 2 shows my data now in alphabetical order, which is great however I would like the top 2 records to be ordered by id
Image 3 shows how I would like my data to look
Could someone help with my query please?
i assumed id is an integer. You can use conditional CASE in the ORDER BY clause.
Note for the first expression case when code in ('LUX-INT', 'LUX-CONT') then -id end desc, it will return id or NULL. As NULL will comes first in ORDER BY, I use DESC and negate the id value so that id is in ascending order
order by case when code in ('LUX-INT', 'LUX-CONT') then -id end desc, code
use case when
SELECT * FROM tableName ORDER BY case when code in ('LUX INT','LUX-CONT') then id else code end
I would write this as:
order by (case when code in ('LUX-INT', 'LUX-CONT') then 1 else 2 end), -- put the special codes first
(case when code in ('LUX-INT', 'LUX-CONT') then code end), -- order them alphabetically
id -- order the rest by id
This works regardless of the types and collations of the underlying columns.
My requirement is to get the List of Diagnosis based on the most used Diagnosis. So, to achieve that I have added one Column named DiagnosisCounter in the tblDiagnosisMst Table of the database which increases by 1 for each Diagnosis the each time user selects it. So, my query is like below:
select DiagnosisID,DiagnosisCode,Name from tblDiagnosisMst
where GroupName = 'Common' and RecStatus = 'A' order by DiagnosisCounter desc,
Name asc
So, this query is helping me to get the list of Diagnosis but in descending order for Diagnosis and then alphabetically for Diagnosis Name. But now my client wants to show only 20 most used Diagnosis name at the top and then all the names should appear in alphabetical order. But unfortunately I am stuck in this point. It would be so appreciative if I get your helpful advice for this problem.
This should do the trick:
;With Ordered as (
select DiagnosisID,DiagnosisCode,Name,
ROW_NUMBER() OVER (ORDER BY DiagnosisCounter desc) as rn
from tblDiagnosisMst
where GroupName = 'Common' and RecStatus = 'A'
)
select * from Ordered
order by CASE WHEN rn <= 20 THEN rn ELSE 21 END,
Name asc
We use ROW_NUMBER to assign the numbers 1-x to each of the rows, based on the diagnosiscounter. We then use that value for the first ORDER BY condition if it's in 1-20, and all other rows sort equally in position 21. The second condition is then used as a tie-breaker to sort those remaining row by name.
Try this
SELECT TOP 20
* FROM tblDiagnosisMst ORDER BY DiagnosisCounter;
In the above t-sql table I would like very much for the Total row to appear at the bottom. I have been wracking my head against this and in all of my other Queries simply using ORDER BY Status works as Total is alphabetically much farther down the list than most of our row values.
This is not the case here and I just can't figure out how to change it
I'm pretty new to sql and I'be been having a lot of difficulty even determining how to phrase a google search. So far I've just gotten results pertaining to Order By
The results of a select query, unless an order is explicitly specified via an 'order by' clause, can be returned in any order. Moreover, the order in which they are returned is not even deterministic. Running the exact same query 3 times in succession might return the exact same result set in 3 different orderings.
So if you want a particular order to your table, you need to order it. An order by clause like
select *
from myTable t
where ...
order by case Status when 'Total' then 1 else 0 end ,
Status
would do you. The 'Total' row will float to the bottom, the other rows will be ordered in collating sequence. You can also order things arbitrarily with this technique:
select *
from myTable t
where ...
order by case Status
when 'Deceased' then 1
when 'Total' then 2
when 'Active' then 3
when 'Withdrawn' then 4
else 5
end
will list the row(s) with a status of 'Deceased' first, followed by the row(s) with a status of 'Total', then 'Active' and 'Withdrawn', and finally anything that didn't match up to an item in the list.
ORDER BY CASE WHEN STATUS = 'Total' THEN 'zzz' ELSE STATUS END
In SQL Server (and most other databases), you can use case to sort certain statūs above others:
order by
case Status
when 'Total' then 2
else 1
end
, Status
In MS Access, you can use iif:
order by
iif(Status = 'Total', 2, 1)
, Status
You can use conditional expressions in order by:
order by (case when status = 'Total' then 1 else 0 end),
status
I have the following query:
SELECT a.field_eventid_key_value, a.field_showdate_value, b.nid , c.nid AS CNID
FROM content_type_vorfuehrung AS a
LEFT JOIN content_type_movies as b ON a.field_eventid_key_value = b.field_eventid_value
LEFT JOIN content_type_sonderveranstaltung as c ON a.field_eventid_key_value = c.field_sonderveranstaltungid_value
WHERE /* something */
GROUP BY a.field_eventid_key_value, a.field_showdate_value,
ORDER BY a.field_showdate_value ASC,a.field_showtime_value ASC
(where clause removed since it's irrelevant to the question)
This pulls data from 3 different tables and sorts it according to the "showdate" field in the first table. This is used in a PHP function that returns an array with the results.
Now there is a new requirement: The table "content_type_movies" in this query has a field that's supposed to be a boolean (actually it's an int with a value of either "0" oder "1"). This field is supposed to override the chronological ordering - that is, results where the field is "true" (or "1" respectively) should appear at the beginning of the result array (with the remaining entries ordered chronologically as before).
Is this at all possible with a single query ?
Thank you in advance for your time,
eike
You can use:
ORDER BY b.MyIntField DESC,
a.field_showdate_value,
a.field_showtime_value
where MyIntField is the field that is either 1 or 0 that you want to sort first.
ORDER BY a.content_type_movies DESC, /*then other fields*/ a.field_showdate_value ASC,a.field_showtime_value ASC
that should place all rows with content_type_movies=1 first then others.
