Alternative To CASE In The Order By Statement?

Feb 15, 2008

 The query below at the bottom works, but when I try to add the line below (a third line/argument in the CASE statement) then I get an error. It is not possible to have a table name and a DESC (sort order) in the same CASE line/argument. Are there other ways to accomplish this, because I would like to sort with both "h.ObjectType" and "h.ObjectType DESC"?

             WHEN @SortBy = 2 THEN h.ObjectType DESC
 
 
    SELECT weight, ObjectText.ObjectId, ObjectText.ObjectType, ObjectText.Title, ObjectText.ShortText
    FROM @hits h INNER JOIN ObjectText ON h.id = ObjectText.ObjectId AND h.ObjectType = ObjectText.ObjectType
    WHERE ObjectText.LanguageCode = @LanguageCode
    ORDER BY
        CASE WHEN @SortBy = 0 THEN weight
             WHEN @SortBy = 1 THEN h.ObjectType
        END
    DESC

Regards, Sigurd

Transact SQL :: Order By Used With Case Statement

I use Order By Used with Case Statement and may be this is the reason for which i am getting error

Windowed functions can only appear in the SELECT or ORDER BY clauses.

Here is my complete sql where i use Row_Number function for pagination with sorting.

DECLARE @StartIndex INT
DECLARE @EndIndex INT
DECLARE @SortColumn VARCHAR(MAX)
DECLARE @SortDirection VARCHAR(MAX)
SET @StartIndex = 1

Error Using Case Expression In Order By Statement

Feb 22, 2008

I have been trying to get the following Selects to work using a case expression in the order by section.

I know I can easily separate out the two statements but I want to do a select using the case statement below ;
however, I keep getting error 16 --"Order by items must appear in the select list if the statement contains a union.

If remove the case statement and put order by "internalID desc" I receive no errors. Moreover, when I take out the union statement and execute the two select statements with each including the case expression it runs as planned.

Can anyone tell what the problem is here? I have combed the web looking for an answer, but it seems that the statement is valid.


Thanks
J
declare @date
set @date = '2001'



select internalID from section_data_v3

union

select internalID from section_data_v4

order by
case when (@date = '2001') then internalID end desc

Using Case Statement To Determine Order By Field And Direction (asc Or Desc) When Using Row_number

Aug 21, 2007

I am trying to order by the field and direction as provided by input parameters @COLTOSORTBY and @DIR while using a CTE and assigning Row_Number, but am running into syntax errors.

Say I have a table called myTable with columns col1,col2,col3,

Here's what I'm trying to do

with myCTE AS
(
Select
col1
,col2
,col3
,row_number() over (order by
case when(@DIR = 'ASC') then


case when @COLTOSORTBY='col1' then col1 asc
when @COLTOSORTBY='col2' then col2 asc
else col3 asc
end
else

case when @COLTOSORTBY='col1' then col1 desc
when @COLTOSORTBY='col2' then col2 desc
else col3 desc
end
end
from myTable
)



Please let me know what i can do with minimal code repetition and achive my goal of dynamically sorting column and direction. I do not want to use dynamic SQL under any circumstance.

Thanks.

Alternative To IF In This Case

Oct 24, 2007

Hey guys,
What would be a better / more elegant solution to something like

IF(@areaCode = '111' OR @areaCode = '222' 0R @areaCode = '333')
BEGIN
//do something
END

that uses less OR's in an IF statement?

Problem Using Result From CASE In Another CASE Statement

Nov 5, 2007

I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.

Previously, I had been duplicating the CASE logic for both columns, like so:




Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...






This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.

This is what I'd like to do:



Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,


shipment_status_text =

CASE shipment_status

WHEN 1 THEN 'Condition 1 text'

WHEN 2 THEN 'Condition 2 text'

WHEN 3 THEN 'Condition 3 text'

WHEN 4 THEN 'Condition 4 text'

ELSE 'Error'

END,
...remainder of SQL view...


This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.

Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?

Thanks,

Jason

TSQL - Use ORDER BY Statement Without Insertin The Field Name Into The SELECT Statement

Oct 29, 2007

Hi guys,
I have the query below (running okay):



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01

The results are just as I need:


Field01 Field02

------------- ----------------------

192473 8461760

192474 22810



Because other reasons. I need to modify that query to:



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:

Field02

----------------------

22810
8461760

And what I need is (without showing any other field):

Field02

----------------------

8461760
22810


Is there any good suggestion?
Thanks in advance for any help,
Aldo.

2 Case Statements In Order By

Oct 31, 2013

It will be part of the stored proc, but for now I couldn't even get it running in ssms. It will be two parameters/variables, one for order by column name and other for order by direction, i.e. desc or asc.I have tried following three ways, but none is working:

(1)
order by case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Desc' then A_ID end desc
case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Asc' then A_ID end asc

(2)
order by case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Desc' then A_ID desc end
case when @Sort_by= '[A_ID]' AND @Sort_Dir ='Asc' then A_ID asc end

(3)
ORDER BY CASE @Sort_by when '[A_ID]' then [A_ID] end
Case @Sort_Dir when 'Desc' then desc end

Transact SQL :: CASE Order Of Evaluation

Sep 24, 2015

I have the following query in a user-defined function. It accepts a single string parameter, but for the sake of simplicity, I have substituted actual strings in the query. It basically checks the passed string. If it ends with "Id", it strips off the "Id" and returns the resulting string. If it ends with "Id" followed by a digit, it strips that off and returns the string.

SELECT CASE
WHEN LEN('IncidentViolationId') > 2 AND RIGHT('IncidentViolationId', 2) = 'Id' THEN LEFT('IncidentViolationId', LEN('IncidentViolationId') - 2)
WHEN PATINDEX('%Id[0-9]', 'IncidentViolationId') > 1 THEN LEFT('IncidentViolationId', PATINDEX('%Id[0-9]', 'IncidentViolationId') - 1)
ELSE 'IncidentViolationId' END

This code has worked flawlessly for quite some time and all of a sudden I get "Invalid length parameter passed to left function". I understand why LEFT() would normally fail if I passed it a -1 for the second parameter, but in this scenario, asI understand it, it never should have reached the second WHEN condition since the first one evaluates to true. Why and why all of a sudden?

Case Statement Error In An Insert Statement

May 26, 2006

Hi All,
I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance.
My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.

Here is my code:
Insert into myTblA
(TblA_ID,
mycasefield =
case
when mycasefield = 1 then 99861
when mycasefield = 2 then 99862
when mycasefield = 3 then 99863
when mycasefield = 4 then 99864
when mycasefield = 5 then 99865
when mycasefield = 6 then 99866
when mycasefield = 7 then 99867
when mycasefield = 8 then 99868
when mycasefield = 9 then 99855
when mycasefield = 10 then 99839
end,
alt_min,
alt_max,
longitude,
latitude
(
Select MTB.LocationID
MTB.model_ID
MTB.elevation, --alt min
null, --alt max
MTB.longitude, --longitude
MTB.latitude --latitude
from MyTblB MTB
);

The error I'm getting is:
Incorrect syntax near '='.

I have tried various versions of the case statement based on examples I have found but nothing works.
I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.

Hi all,
I was wondering if there is any way in an sql statement to check whether the data your trying to get out of the DB is of a particular type, ie. Int, char etc. I was thinking about a case statement such as

</code>
 
This has to be included in the sql statement cause I need this field to get other data.
Any thoughts on how to achieve this would be greatly appreciated.
 
If I’m in the wrong thread section please advise of best one to get help in.

I could like to use a Case statement to determine if there is Null. If so, then output N/A in place of the Null. So then my possible valus are Yes, No, and N/A.

Any clues?
