Transact SQL :: Calculated Fields Stop Working When There Are 10 Or More Rows In A Table
Nov 4, 2015
Setup:
Windows Server 2003 R2 - Enterprise - SP2 - 32 Bit
SQL Server 2014 Express - 32 Bit
Problem: I have a calculated field on a PO table that adds up item prices on an Item table to get the total PO value. This works as expected until there are at least 10 rows in the PO table. From the 10 row on the calculated field stops working and only shows 0.
I have experienced this before and it seems like calculated fields break on the 10th row of a table and onward.
My PO table
CREATE TABLE [dbo].[PO](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Quote_Number] [varchar](max) NULL,
[Customer] [varchar](max) NULL,
[CustomerPO] [varchar](max) NULL,
[PO_Received_Date] [datetime] NULL,
[Total_PO_Value] [decimal](18, 2) NULL,
[Code] ....

Hello all,my first post here...hope it goes well. I'm currently working onstored procedure where I translated some reporting language into T-SQLThe logic:I have a group of tables containing important values for calculation.I run various sum calculations on various fields in order to retrievecost calculations ...etc.1) There is a select statement which gathers all the "records" whichneed calculations.ex: select distinct Office from Offices where OfficeDesignation ='WE' or OfficeDesignation = 'BE...etc.As a result I get a list of lets say 5 offices which need to becalculated!2) A calculation select statement is then run on a loop for each ofthe returned 5 offices (@OfficeName cursor used here!) found above.Anexample can be like this(* note that @WriteOff is a variable storing the result):"select @WriteOff = sum(linecost * (-1))From Invtrans , InventoryWhere ( transtype in ('blah', 'blah' , 'blah' ) )and ( storeloc = @OfficeName )and ( Invtrans.linecost <= 0 )and ( Inventory.location = Invtrans.storeloc )and ( Inventory.itemnum = Invtrans.itemnum )"...etcThis sample statement returns a value and is passed to the variable@WriteOff (for each of the 5 offices mentioned in step 1). This is donearound 9 times for each loop! (9 calculations)3) At the end of each loop (or each office), we do an insert statementto a table in the database.

I am trying to JOIN table on datetime column truncated to full minutes with other table, where I store time intervals (in order to have all minutes in result even when there was no event in main data table).
SELECT
dateadd(minute, datediff(minute, 0, StartTime), 0) as StartTimeMinute
,ApplicationName
,COUNT(*) as Requests
FROM dbo.Profiler as p INNER JOIN dbo.MinuteIntervals as i ON i.TIMEVALUE = p.StartTimeMinute
WHERE EventClass IN (10,12)
GROUP BY dateadd(minute, datediff(minute, 0, StartTime), 0), ApplicationName
ORDER BY StartTimeMinute
How to join on p.StartTimeMinute? I do understand why this doesn't work, as p.StartTimeMinute is calculated in my query, so JOIN cannot find it in original p table.

Hello I am new to SSIS and learning as I go. Any guidance to my questions would be appreciated.
I wrote a script that takes the current date and subtracts a number of days/months from this date. I then attempted to use an SQL Task as a select with a parameter using the calculated date from the script. I was not successful in doing this. While performing searches on the WEB with the hopes of finding a solution I came upon the following text in the Microsoft forum under EXECUTE SQL TASK.
When you use an OLE DB Connection Manager, you cannot use parameterized subqueries because the Execute SQL task cannot derive parameter information through the OLE DB provider. However, you can use an expression to concatenate the parameter values into the query string and to set the SqlStatementSource property of the task.
Having come upon this statement I moved on to putting together an OLE DB SOURCE with a Flat File Destination. The SQL that I wrote is:
SELECT BP_ID, INVC_NBR, INVC_DT, BUS_ADD_DT
FROM DW.CUST_SALE_ADDR
WHERE (BUS_ADD_DT = ?)
The flat file destination was mainly used to confirm the select.
Having confirmed my select, I changed the select in the OLE DB SOURCE as follows:
DELETE FROM DW.CUST_SALE_ADDR
WHERE (BUS_ADD_DT = ?)
I also removed the Flat File Destination. Needless to say when I tried to run the package I did not get very far as a package validation error was encountered since there were no output columns.
Can you share how I should go about peforming the delete as described from the table based on a calculated date? And am I not understanding the comment regarding the SQL Statement and the use of parameters?
Thank you and God Bless.

Hi people
My users are having troubles with link to default drillthrough report when reports are exported to excel (they REALLY don't like this behavior ), so I decided set all of them disabled in report model, this work fine, but calculated field in reports has this drillthrough link.
Let me show you the situation. Entity Product has an UnitaryCost field, I set the EnableDrillthrough Property in False so when I export a report with this field, no link is shown.
But if I create in the report a calculated field Round(UnitaryCost) this field has a Drillthrough Link
Is this the standard and expected behavior? or its simply a BUG?
Have I done something wrong in my model? and in this case, How I can correct this?
regards.
Julio Diaz.

This doesn't necessarily belong in this forum, but I'm starting here in the hopes of getting some direction.
Business users have asked me to "map" a spreadsheet to our Datawarehouse. The spreadsheet contains a lot of calculations.
I created a first pass, but it was difficult to map the Analysis Services cube data to the spreadsheet data and in the process I had to hard code a lot of things that will make the spreadsheet less flexible for additional data.
So my question is, where is the best place to put calculated fields. In my SQL Statements, in ths SSIS transformations, or in the Analysis Cube?
Any help, or pointers to more information, would be greatly appreciated.

I had made some calculated fields within my data set. Later I had to change my stored procedure. When I refreshed my data set my calculated fields disappeared. Is there a way to not lose your calculated fields in a dataset when you refresh it?

Hey
I have a statement that has been running great for the past hour but now it will not pull the info any longer and just gives me a null
DECLARE @Text VARCHAR(2000)
SELECT @Text = COALESCE(@Text + '', '') + x.memotext
FROM (SELECT TOP 100 PERCENT memotext FROM customermemoheader WHERE memonumber = 'TERMS' and customernumber = '0009' ORDER BY seqnumber) AS x
SELECT @Text AS MemoText
I have verified in the tables that the info is there by running the select statement from within the (). It has worked for 8000 records and now it no longer works. Any help would be much appreciated.

I have a table which has been partitioned on BIGINT column.
Partitioned_Table (ID BIGINT, Name VARCHAR(10), Gender VARCHAR(2))
I have a left range partition function on ID column.
CREATE PARTITION FUNCTION Partition_Function ( BIGINT )
AS RANGE LEFT
FOR VALUES ( '20150601000', '20150602000', '20150603000' );
That means the first partition is ID >= 20150601000 to ID < 20150602000.
I have to switch in a table into an empty partition.
Switching_In_Table(ID BIGINT, Name VARCHAR(10), Gender VARCHAR(2))
Before the switch in, I am creating a CHECK constraint on Switching_In_Table CHECK(ID LIKE '20150625%') Can I use like clause in this scenario?

Hi ,
I have created a calculated data field for one of my data set. I use it for a table in my report.
But when I try to preview it, visual studio crashes and I get the following error message.
"An error occured during local report processing. An internal error occured on the report server.see the error log for more details."
I have not installd servers on my machine(only the sql tools). So I can not see error logs either.
Does any one know why this happenes?
Thanks

Time columns go up to Dec 07. But I did not show all the columns.
The values are calculated as follows.
Field value for Jan07 = (No of Loans pass due in Jan07 / Total No of loans disbursed in Jan07)
Repayment due date is 5th of every month. if smbody does not pay on 5th, its considedred as pass due.
Source data tables look like this.
LoanTable(Disbursed date, userID, Amount, Status)
CreditTier table (Credit Tier, Rate) - Seems like no relationship with Loan table
we can identify pass due loans from status field in loan table. Status appears as 'Deliquency'.
Please Can any one help me to create this report?

We have about 10 sites using SQL Server 2000 SP1 or 3 or 3a, across two servers. The publisher/distributor performs transactional replication on three databases to the 'secondary' server.
Nearly all of the sites, at one time or another have experienced the indices on one of the tables simply stop working. Its always the same indices on a table that can have between 70,000 and a 300, 000 rows.
Before I start posting schema or index details anyone come across this before?

Ok I have three columns in my database that deal with ratings of individual ads. One is called totalrating, one is totalvotes, and one is averagerating. TotalRating gets incremented with the rating and totalvotes is incremented by one when someone votes. Then averagerating is a calculated column which divides the totalrating by the totalvotes. The problem is unless I manually set totalrating and totalvotes to 0, the stored procedure does not work. They both remain null. I tried to set the default value for each column to 0, which visual studio changed to ((0)). Maybe I am doing this wrong. If someone could help me I would really appreciate it. Thanks so much.

I have a problem.... I have a TSQL procedure that calculates employee overtime based upon days 1-5 of week being "in-week", and days 6-7 oweek being week-end overtime. The resulting data is then mailed to dept managers. My problem: for some reason the calculated colums are being generated at a width of 40 char per column. I somehow need to reduce the width to 8-10 characters per colum (this will eliminate the wraping that I currently get in my e-mails)... Any help would be appreciated... Thanks..Tom

Hi
This may seem amazing and a stupid question but:
Consider there is a parent table A and child table B and we want to write a query that has some fields from A and a calculated field which indicates whether A has any child record in B or not. The Value 1 means Yes and 0 means No. Has anybody an idea to write this in SQL Server?

Hi all
I have a calculated fields in report designer such as a + b + c + d. In sql server if I run this query
select a + b + c + d from table1
and any of a,b,c or d is null, the result is null.
whereas in calculated fields, it does not return null but infact ignores the null value and treats it as zero.
I want my calculated field to be null if any of the values are null.
Is it possible? I cannot use the isNothing function because I have too many fields and it will be quite cumbersome.
Thanks

Hi everyone:
I am developing an SSRS report over a cube. When I drag and drop fields, it works fine. it runs in a few minutes. I am selectinng only from a single day - about 10,000 records. However, when I add some calculated fields it takes much longer. It's been running for 7 hours. The calculated fields fields are pretty simple. Some are selection of one field over another depending upon the value of a 3rd field. One is two fields multiplied together. One is a constant times a field. Something's obviously wrong here. Anybody seen this or have a solution?

Help!
I have converted my Access Jet database to a SQL Server database. In Access, I had many functions that I created to use in my queries. SQL Server does not allow for functions to be created. So, I had to create procedures in SQL Server to perform what my functions did.
I am trying to use the procedures I created on calculated fields within my SQL statement in my view. It returns an error stating that the procedure is not recognized.
How can I create functions to be used in my query?
Thanks.

Hi,
I have three data sets. Data Set A is bound to my table in my report. There are also Data Sets B and C. All three data sets have the identical columns. I have setup data set A so that all of its fields are "Calculated". The calculation for each field will either pick the field from data set B or data set C based upon a parameter called BorC. So the calcualted fields in data set A look like the following:
=iif(Parameters!BorC.Value, First(Fields!MyField.Value, "dataset_B"), First(Fields!MyField.Value, "dataset_C"))
Problem is when I run the report I get internal error. Is it possible to populate one data set from the fields of another data set? If so is there some trick to doing this? Stripping this example down to one column in each of the data sets, and then just directly setting data set A from either B or C still gives me the same error. SO I set the one field in data set A to the following and it still doesn't work:
=First(Fields!MyField.Value, "dataset_B")
OR
=First(Fields!MyField.Value, "dataset_C")
This leads me to believe there is some fundamental problem with using another data set in a Calculated field. Since I think I have done this before I am convinced I am doing sommething wrong.
Any advice you have for me would be greatly appreciated!
Thanks.

Hi
I am new to SQL Server and am migrating another database
In my original database I have a default(constant) type field and a calculated field both of which call the same user defined function: GetMyUID()
My Function GetMyUID() returns the current date, time and users initials, i.e. "20080522T09:31:15.250LSG"
When a record is first created both fields have identical values
As the record is updated over time my constant field stays constant and my calculated field reflects the time the record was last updated and the initials of that person. So my first field is called 'Created' and my second is called 'Updated'
I would have thought that something like this would be a pretty bog standard and very straightforward requirement in any database
However in SQL I am getting error messages about the return value being non deterministic
I searched the web and found advice that to sort the problem I need to use WITH SCHEMABINDING in my function definition
Unfortunately I am still getting the same 'non deterministic' error
I wonder if (in the quest to not have an overlong field) by looking up the persons initials from a 'STAFF' file rather than leaving the username in full tacked on to the end that this is causing the problem?
I can't imagine that what I am trying to achieve is rocket science but unfortunately have not been able to find any resource on the web that solves this issue for me
In desperation I turn to you
Please help (preferably by letting me have a few lines of code that return the current date/time followed by the username lookup of a Username's initials, here is a snippet of my code...
RETURN (Convert(VarChar(8),@DateTimeNow,112)+ Right(Convert(VarChar(30),@DateTimeNow,126),13)+dbo.myInitials())
Where the dbo.myInitials() calls:
RETURN (SELECT STAFF.Code from dbo.STAFF where STAFF.Login = dbo.myLogin())
and dbo.myLogin() calls
return UPPER(Right(System_User,PATINDEX('%\%',System_User)))

I am copying a simple table from a Sql Server 2005 database to an *.sdf mobile database.
I am brand new to SSIS and I am probably doing something wrong. But after executing the SSIS package all the rows and all the fields are NULL in the destination database. I put a datagrid viewer between the OLE DB Source and the Sql Server compact edition destination and I can see the real data which is obviously not ALL NULL.
Does anyone have a clue as to why it would be doing this?
Any help would be much appreciated.

I'm using the SQL below to work out recruitment figures. The query works well, but I now need to build this query into a DotNet application as a webpage. I therefore need to declare and manipulate the values such as 'Total', 'Jan' to 'Dec' and 'YearRecruited' in order to write these values into my chosen data control. I therefore need to know the datatypes of these calculated values.
Total I think is straightforward as DNAScreeningID is an int datatype. But what about the others?
SELECT YEAR(SamplingDate) AS YearRecruited,
COUNT(CASE WHEN month(SamplingDate) = 1 THEN DNAScreeningID END) AS 'Jan',
COUNT(CASE WHEN month(SamplingDate) = 2 THEN DNAScreeningID END) AS 'Feb',
COUNT(CASE WHEN month(SamplingDate) = 3 THEN DNAScreeningID END) AS 'Mar',
COUNT(CASE WHEN month(SamplingDate) = 4 THEN DNAScreeningID END) AS 'Apr',

I used PP in Excel 2013 before and the area I'm talking about was at the bottom of the PP window. Now I'm with a new company who has Excel 2010 so I downloaded the PP add-in for Excel 2010. It is version 10.50.4000.0. This add-in does not have a calculated fields/measures are at the bottom of the PP window. Is it just a matter of 2010 vs. 2013 or is there a way to turn the frame area I'm talking about on?
