T-SQL (SS2K8) :: Using Case Within PIVOT Portion Of Crosstab Query
Apr 13, 2015I have created a crosstab query using the Pivot statement that returns the expected results. The results look similar to the sample below:
ItemKey Description Aflatoxin Coliform Bacteria E_Coli Fumonisin Melamine Moisture Mold Salmonella Vomitoxin (DON) Yeast
1000 Item1000 1 0 0 1 0 1 0 1 1 0
1024 Item1024 1 0 0 1 0 1 0 1 1 0
135 Item135 1 0 0 1 0 1 0 1 1 0
107 Item107 0 0 0 0 0 1 0 1 1 0
106 Item106 1 0 0 1 0 1 0 1 1 0
I'm using this statement to create the result set:
SELECT ItemKey, Description, Aflatoxin, [Coliform Bacteria], [E_Coli],[Fumonisin],
Melamine,Moisture, Mold, Salmonella, [Vomitoxin (DON)], Yeast
FROM
(SELECT tblInventory.ItemKey, tblInventory.Description,
jctProductClassificationRequiredTest.ProductTestClassID, tlbTestType.TestDescription
[Code] .....
Instead of doing a Count for the Pivot (the count will always be either 0 or 1 due to the design of the table being used), I would like to return an "X" for those records with a count of 1, and return a blank (otherwise null) for those records with a count of 0. So, the result set would look like:
ItemKey Description Aflatoxin Coliform Bacteria E_Coli Fumonisin Melamine Moisture Mold Salmonella Vomitoxin (DON) Yeast
1000 Item1000 X X X X X
1024 Item1024 X X X X X
135 Item135 X X X X X
107 Item107 X X X
106 Item106 X X X X X
I tried using a Case statement within the PIVOT portion, but I either did it incorrectly or it's not possible to do use a Case within the Pivot. Can I easily accomplish this?

Can You Unpivot On Multiple Keys With The Unpivot Transform
Oct 17, 2006Hi all,
I have more than 1 set of columns I'm trying to normalize, can an unpivot transform handle 2 unpivots around DIFFERENT keys in the same transform?
If not, would the suggestion be unpivot into temp tables for whatever needs normalizing, than run an update query to generate the row that is desired?
Thanks in advance.

T-SQL (SS2K8) :: Case For Field Type
Jun 7, 2014Is there an easy way to send back to my C# program the pascal case of a field type? If you get the parameters or columns for a table or procedure the type is in all lowercase (varchar instead of VarChar). But in C#, it is in an enum (SqlDbType) that has the variables as mixed case so you can't compare them and just pass the type. You need to figure out what the case should be - varchar should be VarChar and bigint should be BigInt.

T-SQL (SS2K8) :: Case Statement In The Where Clause?
Jun 5, 2015I have a population split between two vendors. One gets last names between A and R, the other the rest. Now, on a given date vendor 1 gets everybody.
I can accomplish this with a case statement on the upper range (R or Z), but it seems I should be able to do this without testing at all after the turnover date.
A small bit of the code:
declare @get_date datetime = convert(char(10),getdate(),101)
select top 10 pt.pt_id, pt.last_name
fromsmsmir.mir_acct a join smsmir.mir_pt pt on (a.src_sys_id = pt.src_sys_id
and a.pt_id = pt.pt_id
and a.from_file_ind = pt.from_file_ind

Seems I should be able to not test the last name after the turnover date, but I can't figure out how.

T-SQL (SS2K8) :: How To Execute SP In Select Case Statement
Mar 20, 2014I am a junior dba not a developer. So I'm just trying to get use to write code in T-SQL.
Anyways, I have a table which is dba.dbhakyedek.
Columns are
dbname, username, class_desc, object_name, permission_name, state_desc
I have statement
select case
when class_desc='OBJECT_OR_COLUMN' then 'GRANT '+permission_name+' ON '+'['+left(object_name,3)+'].'+'['+substring(object_name,5,len(object_name))+ '] TO '+username
WHEN class_desc='DATABASE_ROLE' THEN EXEC sp_addrolemember N'object_name', N'MC'
end
from dba.dbhakyedek
where username='MC'
This statement was running successfully until exec sp_addrolemember thing. I just learned that i can't call a sp in select case but i couldnt figure out how to do it.
T-SQL (SS2K8) :: Update With Case Statement Not Working?
May 29, 2014I have a situation where I want to update a column if and only if it is null.
UPDATE Employee
SET VEmployeeID = CASE WHEN E.VEmployeeID IS NULL
THEN ves.VEmployeeID
END
FROM Employee E
INNER JOIN VEmployeeStaging VES
ON E.EID= VES.EID
But what happens is when I run the procedure every other time I run it, it changes everything to null. The other times it puts the VEmployeeID in.
So what is happening is the times when it is not null (where it is not supposed to do anything) it puts a null in. The next time it works.
T-SQL (SS2K8) :: Dividing Two Rows Within CASE Statement
Jul 28, 2014I was given the task to come up with a result set based on certain criteria:
Please add one row for each offer code
1) Opt-in rate by offer code: This can be calculated by dividing XXX Inventory with lead / XXX Inventory (A)
The report should read something like below:
Example result set:
Log Date: OfferLetter OfferCode DailyCount
2014-07-20 A XXX Inventory (A) 108
2014-07-20 A XXX Inventory with lead 54
2014-07-20 A XXX Inventory Opt-in Rate: 50%
There are 12 different groupings and OfferLetter A is just one of them.
Below is the code that is written to date:
DECLARE @Start datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 8), 0)
DECLARE @End datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 1) + 1, 0)
DECLARE @Today datetime = DATEADD(day, DATEDIFF(day, 0, GETDATE() - 1), 0);
SELECTDT.OfferCode, DT.OfferCodeDesc
INTO#tempOfferCodes
[Code] ....
The issue I'm having is that the values I need to divide by are in fact, a result set from the CASE statement. It's been a long time since I've done anything like this.

Case Function In T-SQL
Sep 13, 2007Wondering if possible to use case function in where clause of T-SQL statement. I have this application that needs to get the recordsets based on the day of the date selected that is @dDay in one of these set of values {0,7,14,21, more). Though, I know that if I use either of this:
datediff(dd,@startdate,@today) = @dDay
or convert(varchar(12), @startDate, 101) between convert(varchar(12), @today, 101) and convert(varchar(12), dateadd(dd,@dDay, @today), 101)
It will work for only the values that are specific as in number but what of if "more" is selected which means that from that day upward, can i use this T-SQL to accomplish this. PLease help
Any suggestion is welcome. thanks

Case / Switch Function Help
Jun 9, 2004Starting to play around with SQL server at work and this is my question:
In the query design mode in access I can make one of the fields an expression that is driven by a built-in switch function.
i.e. Switch([CategoryName] Like "Beverage","Drink",[CategoryName] Like "Cheese","Dairy")
This results in the additional column field I created to display "Drink" for each record that has the CategoryName = "Beverage", and "Dairy" for "Cheese".
Can I do something like this in SQL server in the view designer itself, or do I need to make a user defined function and call it?
Thanks in advance for any help.

SQL 2012 :: Using Count Function And Case In One Select Statement
Jul 9, 2014I am selecting the count of the students in a class by suing select COUNT(studentid) as StCount FROM dbo.student But I need to use a case statement on this like if count is less than 10 I need to return 'Small class' if the count is between 10 to 50 then I need to return 'Medium class' and if the count is more than 50 then 'Big class'.
Right now I am achieving this by the following case statement
SELECT 'ClassSize' = CASE WHEN Stcount<10 THEN 'Small Class'
WHEN Stcount>=10 and StCount<=50THEN 'Medium Class'
WHEN Stcount>50 THEN 'Big Class'
END

Problem With PATINDEX Function For Case-sensitive Information
Aug 21, 2007Hi,
My database is not case-sensitive, but I want output like...
SELECT patindex('%[A-Z]%','gaurang Ahmedabad')
The output should be first occurrence of uppercase A to Z, so output should be 9 it should not be 1.
Above query is giving output as 1 bcoz the 1st character in the expression is 'g' and it is in A to Z, but this is not capital 'G'. The 1st capital letter in the expression is 'A' (9th character in the expression).
Is there anyway to achieve this using PATINDEX? or Is there any other way to achieve this?
Thanks,
