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.
This is probably a very simple question, but I am just stumped. I am storing different name parts in different fields, but I need to create a view that will pull all of those fields together for reports, dropdowns, etc.
Here is my current SELECT statement:
SELECT m.FName + SPACE(1) + m.MName + SPACE(1) + m.LName + ', ' + m.Credentials AS Name, m.JobTitle, m.Company, m.Department, m.Address, m.City + ', ' + m.State + ' ' + m.Zipcode AS CSZ, m.WorkPhone, m.FAX, m.Email, c.Chapter, m.Active, s.Sector, i.Industry FROM tblMembers m LEFT OUTER JOIN tblChapters c ON m.ChapterID = c.ChapterID LEFT OUTER JOIN tblSectors s ON m.SectorID = s.SectorID LEFT OUTER JOIN tblIndustries i ON m.IndustryID = i.IndustryID WHERE m.DRGInclude = 1
My problem is that I don't know how to test for NULL values in a field. When you concatenate fields that contain NULL values, the entire contactenated field returns NULL. I am not aware of an IF statement that is available within the SELECT statement.
The first thing I would like to accomplish is to test to see if MName contains NULL. If it does I do not want to include + SPACE(1) + m.MName in the clause. Then, if Credentials contains NULL I do not want to include + ', ' + m.Credentials in the clause.
Can someone tell me what I am missing? Is there a function that I can use for this?
Hi, When I try to insert a new record into a table that has a datetime field that allows nulls, a default 01/01/1900 date is inserted instead of null. I recreated the table and set the datatype to smalldatetime and I still get the error. What have I missed?
I have a projects table with 2 foreign key fields that both link to the same employees table because a project has a Package Engineer (PkgEngineerID) and a Contract Administrator (PkgContrAdmin). When I try to insert a record with null values for either or both of these foreign keys I get an error:
The data in row xxx was not commited. The record can't be added or changed. Referential integrity rules require a related record in table 'tblEmployees'. The transaction ended in the trigger. The batch has been aborted.
An insert statement for the above would look something like the following:
I am using a DAL and i want to insert a new row where one of the columns is DATE and it can be 'NULL'. I am assigning SqlTypes.SqlDateTime.Null. But when the date is saved in the database, i get the minvalue (1/01/1900) . Is there a way to put the NULL value in the database using DAL????how can i put an empty date in the database? THANK YOU!!!
Hi, I have fields in my table which allow nulls. Is it efficient to not insert anything (the field automatically shows up as null in this case) and leave or store some value into it. The field is a smallint field?
Hi, i'm new to SSIS and trying to import some csv files (comma delimited) into SQL Server. A NULL value for a CHAR column is correctly regonized as NULl in SQL Server, but a NULL value for of a mapping to a VARCHAR column in SQL Server is not recognized correctly and i get the value "'NULL'" in SQL Server (including the single comma.
Sample:
CSV file contains columns A and B. A and B contains the Text NULL. Column A is mapped to a CHAR field, and column B is mapped to a VARCHAR field in SQL Server. After the import, SQL has the following value: A = NULL as NULL, B 'NULL' as text.
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?
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?
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?
I have a table with some fields. break_mon, lunch_mon, dinner_mon, ent_mon,break_tue, lunch_tue, dinner_tue, ent_tue, .....etcI want to output the sum of the four monday columns as well as the sum ofthe four tuesday columns.I did this withSELECT break_mon+lunch_mon+dinner_mon+ent_mon AS mon_tot,break_tue+lunch_tue+dinner_tue+ent_tue AS tue_totFROM expense_reportI now want to add mon_tot and tue_tot AS total, but SQL is telling me thatit can not find mon_tot. Is there a way to do this? Thanks!DarrenMCP
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.
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'.
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?
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.
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?
use Northwind Go select dbo.Orders.OrderID ,Cast(dbo.Orders.OrderDate As DATE)Order_Date , dbo.Customers.CustomerID , dbo.Customers.CompanyName , dbo.Products.ProductName
[code].....
I cannot use the alias field names as part of additional calculations for new columns.Â
total_Amount and  Grand_Total cannot be done with my skill level.
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:
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!
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...
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',
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.
This is so trivial but I cannot figure out where the calculated fields/measures area is in the PP window. Is there something to toggle it on and off? 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?
I am not sure if this is possible or not, we have two datasets and each one has an additional calculated field which breaks the value JobBilledExVAT into three years.
So it reports for example how much we billed in May 2015, 2014 and 2013.
I have got the table to display this when reporting on one dataset by grouping by year
The datasets both look similar to thisÂ
SELECT  Practice.ibvSalesByJob.JobBilledExVAT  ,Practice.ibvSalesByJob.[Year] FROM  Practice.ibvSalesByJob  INNER JOIN Practice.idvJobType
[Code] ...
The calculated field isÂ
=Switch(Fields!Year.Value = Parameters!Year.Value ,"15", Fields!Year.Value = Parameters!Pre1Year.Value ,"14", Fields!Year.Value = Parameters!Pre2Year.Value ,"13") The field I am looking to add together is below =Sum(Fields!JobBilledExVAT.Value)
If I do the below on the dataset associated with the matrix it displays the sum for each year correctly, I would however like to add the Sum(Fields!JobBilledExVAT.Value) from a different dataset (ABS1M) for the relevant year.
However this adds 2015, 14 and 13 from ABS1M and doesn't add them individually if that makes sense? With the calculated field it only shows Year under the main dataset heading not 15, 14 and 13 separately.
I was think of using LOOKUP however I don't know how this would work as 15, 14 and 13 are not displayed under the dataset.
I have created 60 queries and added them to my data model in Power Pivot/Excel 2016. I created some calculated fields for one of my queries but I would LOVE to know how to just copy these across all queries in the data model instead of having to create them in the data model for one query at a time. That will take forever.Â

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,
What is the best code pratice to use do the following code,
SELECT fo.no as LNum, fo.name as LName, sum(CASE fo.docnome WHEN "In" THEN fo.etotal ELSE 0 END) as In1, sum(CASE fo.docnome WHEN "In2" THEN fo.etotal ELSE 0 END) as In2, sum(In1+In2)/10 as inDec, from fo group by fo.no,fo.name order by fo.name
instead of
SELECT fo.no as LNum, fo.name as LName, sum(CASE fo.docnome WHEN "In" THEN fo.etotal ELSE 0 END) as In1, sum(CASE fo.docnome WHEN "In2" THEN fo.etotal ELSE 0 END) as In2, ((sum(CASE fo.docnome WHEN "In" THEN fo.etotal ELSE 0 END))+sum(CASE fo.docnome WHEN "In2" THEN fo.etotal ELSE 0 END)))/10 as inDec, from fo group by fo.no,fo.name order by fo.name
I cant use functions and procedures. Is there any better and cleaner way to code this, reusing the calculated values?
Hi everybody,I need some help on calculated values in my database design.I'm creating an accounting / business management application with theusual modules like A/R, A/P, Inventory, etc.I don't know how to handle calculated values in fields like "CustomerBalance", "Inventory Item Qty on Hand", "Inventory Item Qty Last cost"and other similar.I don't want to create fields in the database to store these valuesbut I want to create them on the fly instead. Another thing I preferto do is use code in my application (vb.net) not T-SQL to do this(stored procedure or views), because this way I'm moving businesslogic into SQL; so far all the logic is located in a Business RulesDLL.My question is how can I do that and at the same time achieve "easy"joins.For example:Every time I retrieve some customer's info I need his balance. Let'ssay if my query is:SELECT CustomerID, CustomerName, Address from CustomersWhere CustomerID = ‘xxxxxx'How can I retrieve the balance, when is calculated from other fieldsin other tables, such as Invoices, Credit Memos and Cash Receipts?I thought to use views and add a join to the above query. Is that goodor bad, performance wise?What other options I have?Looking forward for your answer.Thanks in advanced.Stefanos
