Using Case To Subtract To Condition
Sep 30, 2013
I have data for moths which are commulative, for example Feb where month is 02, ecul Jan. + Feb. data. I would like to have the data for only Feb = when month '02' Feb = data for '02' - data for '01'. I would like to writ these commands: For Jan there is no problem to write the command but for other months I am not sure how to write the commands for months other than Jan.
,Jan_qty_1 = case
when [stat_month] = '01' then cast(sum(cast([qty_1_mo] as bigint)) as bigint)
else CAST('0' as int)
end
[Code] ....
here is the data:
ust_code district stat_year stat_monthqty_1_mo
24105220070112619
2410522007022200
2410522007024438
2410522007030
24105220070314434
2410522007042295
2410522007040
2410522007050

Is it possible to have more than one conditions per line? Example below. It works fine if I do this, "When 'M" then 'Yes' But, I am trying to have it to check for more than one. The below example does not work. What can I do to do something like this.
SELECT
FirstName, LastName,
CASE WorkCode
WHEN 'M', 'E', 'F' THEN 'Yes'
WHEN 'C', 'D' THEN 'No'
END
FROM Employees

I've a variable in my SP that I'd like to use to change the format of my output. Try this!
select case when 1=2 then cast(1 as decimal(10,2)) else cast(2 as decimal(10,0)) end
Then this:
select case when 1=1 then cast(1 as decimal(10,2)) else cast(2 as decimal(10,0)) end
Why in either case, the output is returned as n.nn ? Whilst single select expressions (like these):
select cast(1 as decimal(10,2)) -- = 1.00
select cast(2 as decimal(10,0)) -- = 2
Work fine.

For example..
select * from mytable where MyNum = 7
If this brings back more than 1 row, I want to display a message that says,
Print 'There is more than one row returned'
Else (If only 1 row returned), I don't want to print anything.
Can I do this? Thx!

Dear friends,
I'm having a problem... maybe it's very simple, but with soo many work, right now I can't think well...
I need to filter rows in a dataflow...
I created a condition spli to that... maybe there is a better solution...
And the condition is: Datex != NULL(DT_DATE)
(Some DATE != NULL)
[Eliminar Datex NULL [17090]] Error: The expression "Datex != NULL(DT_DATE)" on "output "Case 1" (17123)" evaluated to NULL, but the "component "Eliminar Datex NULL" (17090)" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error.
What is wrong??
Regards,
Pedro

I am trying to write an visibility function to have message shown based on two different IIF conditions:
If behavior is to Add a customer ( if message =NAME ALREADY EXISTS, return " NAME ALREADY EXISTS",   otherwize return " NAME CREATED")If behavior is to Delete a customer (( if message =NAME DOES NOT EXIST, return "NAME DOES NOT EXIST",   otherwize return "NAME SUCCESSFULLY DELETED")
I tried the following which doesn't work:
=IIF((UCase(First(Fields!Message.Value, "DataSetName")) = "NAME ALREADY EXISTS"), "WARNING: NAME ALREADY EXIST", "NAMEÂ CREATED"),
IIF((UCase(First(Fields!Message.Value, "DataSetName")) = " NAME DOES NOT EXIST"), "WARNING: NAME DOES NOT EXIST", " NAME DELETED")

I have a View in SQL,
SELECT dbo.ATTTblAttendance.LogIn, dbo.ATTTblAttendance.LogOut,
ISNULL(DATEDIFF(Hour, dbo.ATTTblAttendance.LogIn, dbo.ATTTblAttendance.LogOut),0) AS TimeWorked
FROM dbo.ATTTblAttendance
Currently, when Login = 1:00 PM and LogOut = 4:30 PM, TimeWorked = 3.
What I need is for TimeWorked to = 3.5
My ASP.NET page has the following:
<asp:TemplateField HeaderText ="Total Hours" >
<ItemTemplate >
<asp:Label ID="TimeWorked" runat="server" Text='<%# Eval("TimeWorked") %>' ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The goal is to take a person's dailt time in and time out, and subtract their AM and PM break time to yield their TimeWorked.
Ex. time in > 8:00 AM,
lunch > :30 minutes
time out > 4:30 PM
Total Time Worked today = 8.0 or 7.45, or 7.5, if the time warrant it.
How I get this to subtract correctly?

Hello everyone. I have a query where I pull all item_codes that start with a 7. I need all the item_codes that start with 7, but I need to subtract the last 3 characters from only the item_codes that are not 71860kit or 71851nggun. How would I be able to accomplish this. What I have below subtracts the last 3 characters from all item_codes including 71860kit and 71851nggun. I want these two to stay in tact when I select them in the query.
This is the Query that I have now!
select datepart(year, date_cust_invoice)as INV_YEAR,
datepart(month, date_cust_invoice)as INV_MONTH,
item_code=left(item_code, len(item_code)-3)
, sum(QTY_SALES)as QTY_SALES_TOTALS, sum(SALES_VAL)as SALES_VAL_TOTALS
from opcsahf
where datepart(year, date_cust_invoice) >= '2003'
and substring(item_code, 1, 1) = '7'
group by datepart(year, date_cust_invoice), datepart(month, date_cust_invoice),
item_code
order by inv_year, inv_month, item_code
All help is appreciated!

Hi all,
I need help writing a query that will subtract the values of 2 rows from the same column to display in the result set. Some background information: a table has a sales column that keeps track of sales by the minute, but this is done in a cumulative manner, i.e, sales at row 3(minute 3) = sales recorded @ minute 2 plus sales @ minute 3. Therefor to get the actual sale at min 3, i would have subtract value at row 2 from row 3. make sense? it sounds very easy but I am having a hard time refering back to the previous row and am dealing with more than 1000 rows. i thought about doing a self join on the table but could not get it to do what i want.
would appreciate any help i can get. thanks

Hi,
I have an implementation of the UDT - 3-dimentional vector. In my code I have implemented add, subtract and multiply methods for the type. I have also implemented overloaded operators for +/-/* in my C# code. Those overloaded operator are working as expected in C# tests. However when I€™m trying to use +/-/* operators in T-SQL over my UDT it returns the following error:
Invalid operator for data type. Operator equals add, type equals Vector.
The following fragment does work:
DECLARE @v1 Vector, @v2 Vector, @v3 Vector;
SELECT @v1 = CAST('1,1,1' as Vector), @v2 = CAST('2,2,2' as Vector)
SELECT @v1 'v1', @v2 'v2', @v1.[Add](@v2) 'v1 + v2'
And this fragment does not work:
DECLARE @v1 Vector, @v2 Vector, @v3 Vector;
SELECT @v1 = CAST('1,1,1' as Vector), @v2 = CAST('2,2,2' as Vector)
SELECT @v1 'v1', @v2 'v2', @v1+@v2 'v1 + v2'
I guess that SQL Server is not aware of the operators€™ overload I have implemented in the C# code. Is there any way to instruct SQL Server to use overloaded operators in the T-SQL so the code will look naturally @a + @b instead of @a.[Add](@b) and as a result use standard summary functions SUM() instead of writing user defined aggregate function for the Vector type field?

Hey all, how do you take the current date and subtract a year from it in a SP?
What I want to do is...
Take the current date when the SP is ran, subtract a year, then if my date field is within that range (higher than the date with the subtracted year) it will continue in the query.
Edit: the answer is..
dateadd(yyyy, -1, getdate()) as Date1

I have a query that uses rollup to get totals and top 101 to restrict the rows to top 100 rows plus the total column. The total column shows total for all rows not just the top 100 which is exactly what i need. The only thing I need now is a row that shows total for all rows that have been excluded, or the total row - total of the top 100.
Here's the query: (Biggest factor i have to keep in mind is query speed.)
Code Block
WITH CTE_name AS (
SELECT TOP 101 b.name,
SUM(ISNULL(CAST(b.launched AS BIGINT),0)) AS quantityPrepared,
SUM(ISNULL(CAST(b.bounced AS BIGINT),0)) AS bounced,
SUM(ISNULL(CAST(b.delivered AS BIGINT),0)) AS delivered
FROM dimension tt
INNER HASH JOIN batch b ON (b.batch_id = tt.batch_id)
WHERE tt.datelaunched >= '11/19/2007'
AND tt.datelaunched < '11/20/2007'
AND tt.id = 1
GROUP BY b.name WITH ROLLUP
ORDER BY SUM(ISNULL(CAST(b.launched AS BIGINT),0)) DESC
)

How can i subtract two columns:
I have table:
   Â
ID COL 1 COL 2
-------------------------
1 200.00 70.00
2 200.00 30.00
3 200.00 90.00
4 200.00 110.00Col1 - COL2
But to continue for each row and value is reduced by the previously value.
My output should be like as:
ID COL 1 COL 2 [COL3 AS RESULT]
-------------------------

2 200.00 30.00 100

We are running sql 2008 R2. We have the JE_DATE field set up as an int. We are trying to subtract 30 days from this date field.
select * from GENERAL_LEDGER
where JE_DATE >= DATEADD(DAY,-30,GETDATE())
In addition to the where clause above we have also tried
where JE_DATE >= DATEADD(dd,-30,GETDATE())
For both we get the following error "Arithmetic overflow error converting expression to data type datetime."

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?
