HI,
I have a problem with using CASE in my database,
Here is the code that I am using but not working
SELECT Computers.[Computer ID], Computers.Model, Computers.[Dell Service Tag], Users.[First Name] CASE WHEN Users.[first name] is NULL THEN Users.[user ID] ELSE Users.[First Name]+' '+Users.[Last Name] AS NAME ENDFROM Computers INNER JOIN Users ON Computers.[Computer ID]=Users.[Computer ID]ORDER BY Users.[First Name];
Could you please tell me where is wrong?Thanks in advance,Azi

I am trying to have all these calulcation int one column under AccessFeeFinal, but it is not working. It was working when I just had the one case statement, but we needed to add another one in because we were getting some blank info in the column. Below are the two statement then I added a third on to show you how I think it should be, but it is not working for me. Please help me out if you can. I was thinking maybe I needed to use an IF Statement.
CASE clm_att1
WHEN 'NG' THEN (clm_H30)*(clio_fee04/100)
WHEN 'NA' THEN '0.00'
WHEN 'AF' THEN (clm_H30)*(clio_fee04/100)*.65
ELSE Null
END as AccessFeeFinal,
CASE clm_att1
WHEN 'NG' THEN (clm_sppo)*(clio_fee04/100)
WHEN 'NA' THEN '0.00'
WHEN 'AF' THEN (clm_sppo)*(clio_fee04/100)*.65
ELSE Null
END as AccessFeeFinal,
CASE clm_att1

Hi
I am trying to use a global variable in a case when and am not getting the correct results. If I use static data, it works fine.
Here is a tableless example, which should return Shipper. Any ideas are appreciated.
Code:
declare @shipperGBS varchar(3000)
declare @sQuote char
set @sQuote = char(39)
set @shipperGBS = 'ACI,ADO,ALD,AMS,AWB'
set @shipperGBS = Replace(@shipperGBS, ',', @sQuote + ',' + @sQuote)
set @shipperGBS = @sQuote + @shipperGBS + @sQuote
select case when ('ACI' IN (@shipperGBS)) then 'Shipper' else 'Consignee' end as ClientCharge

I have a case statement I need to refer to several times in my select statement and it's quite long. I would like to just refer to if by name. I tried to create a variable for the Case statement (see below) but I get an error that says, "
Sub query returned more than 1 value. This is not permitted when the sub query follows =, !=, <, <= , >, >= or when the sub query is used as an expression."
USE GP05
GO
DECLARE @EmpID nvarchar (6)
SET @EmpID = (SELECT CASE WHEN NOT(dbo.BE010130.EMPID_I IS NULL) THEN dbo.BE010130.EMPID_I
WHEN dbo.BE010130.EMPID_I IS NULL AND NOT(dbo.UPR00500.EMPLOYID IS NULL) AND dbo.UPR00600.EMPLOYID IS NULL THEN dbo.UPR00500.EMPLOYID
WHEN dbo.BE010130.EMPID_I IS NULL AND dbo.UPR00500.EMPLOYID IS NULL AND NOT(dbo.UPR00600.EMPLOYID IS NULL) THEN dbo.UPR00600.EMPLOYID
WHEN dbo.BE010130.EMPID_I IS NULL AND NOT(dbo.UPR00500.EMPLOYID IS NULL) AND NOT(dbo.UPR00600.EMPLOYID IS NULL) THEN dbo.UPR00500.EMPLOYID
END FROM dbo.BE010130 FULL OUTER JOIN dbo.UPR00500 ON dbo.BE010130.EMPID_I = dbo.UPR00500.EMPLOYID AND dbo.BE010130.BENEFIT = dbo.UPR00500.DEDUCTON
FULL OUTER JOIN dbo.UPR00600 ON dbo.BE010130.BENEFIT = dbo.UPR00600.BENEFIT AND dbo.BE010130.EMPID_I = dbo.UPR00600.EMPLOYID)
SELECT @EmpID
I can get around this by simply retyping the case statement when I refer to it in the where clause, but I would prefer not to do this. Can someone point a newbie in the right direction? I have 5 case statements in this query and it starts to look pretty ugly when you have to retype them multiple times.
Thanks!

Hello:
I have created an SQL server table in the past on a server that was all case sensative. Over time I found out that switching to a server that is not case sensative still caused my data to become case sensative. I read an article that said you should rebuild your master database then re-create your tables. So after rebuilding the master database, a basic restore would not be sufficient? I would have to go and manually re-create every single table again?
Any suggestions?

We need to install CI database on CS server, and there are some issueswith stored procedures.Database works and have CI collation (Polish_CI_AS). Server hascoresponding CS collation (Polish_CS_AS). Most queries and proceduresworks but some does not :-(We have table Customer which contains field CustomerID.Query "SELECT CUSTOMERID FROM CUSTOMER" works OK regardless ofcharacter case (we have table Customer not CUSTOMER)Following TSQL generate error message that must declare variable @id(in lowercase)DECLARE @ID INT (here @ID in uppercase)SELECT @id=CustomerID FROM Customer WHERE .... (here @id in lowercase)I know @ID is not equal to @id in CS, but database is CI and tablenames Customer and CUSTOMER both works. This does not work forvariables.I suppose it is tempdb collation problem (CS like a server collationis). I tried a property "Identifier Case Sensitivity" for myconnection, but it is read only and have value 8 (Mixed) by default -this is OK I think.DO I MISS SOMETHING ????

I have a database used for a point of sale system
it has a main table with the total amount of a check - the tip
the tip is save in a different table that holds payments the issue is i need to make a statement that finds checks based of the total with the tips added. the table that holds tips can have more then one tip because you can have multiple payments on a check.
The statement i have now is like this
select jc.total + sum(jp.tip) as total from jc innerjoin jp on key
where total <= @max and total >= @min
group by jc.total
but this statement uses total before the tip is added. I am not sure how else to do this any help would be great

Hello All,
I imported a excel file from SSIS and created a table called Lockbox.
To avoid the user from having to change the excel file -it is being imported as is.
I only need 4 fields: [Contract ID] , [Check Number], [Owner ID], [Site ID]
The table I need to import to Transaction has Diffrent Column Names -ex-CustomerID, ResortID.
The columns are in diffrent order.
And I need to add more information into them like UserID = 'Hwells', Trantype = 'MF'
and convert to a diffrent data type [Site ID] to text.
Is their a sql statment that can do this?

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
