How do i generate another computed column that will contail the result of GrandTotal/Total,
where GrandTotal is another value comes from computed column and the Total would be the sum of the Total within SchedularID.
And thats what i have done so far: [Code]....
I'm trying to define a computed column that will contain an auto-incremented number. In other words, I want it to work exactly like identity, but since I can have only one identity column per table, I wanted to make a computed column that reads its latest value and increment it by 1.

Customers of hours buy packs of hours, these are credited and debited on their account. We have a prepayhours table and that has various columns in it, one credit and one debit. I have written a query using the Query building and SQLDS to total these columns, which is fine. What i really want to do is get that query, or if there is an easier way to add up all the debits and subtract them from the total of credits so you would end up with a + or - totalThen with that i can put it into a label or if there was a way to add a row at the end of my gridview which just said total in one column and the total of the hours in the next.
I have some SQL code which seems to work in SQL 2008 but not in the SQL designer for VWD.
CREATE VIEW dbo.prepayhrstotals
AS
SELECT COUNT(Debit) AS cntDebit, COUNT(Credit) AS cntCredit
FROM prepayhrs
GO
SELECT (cntdebit - cntcredit) AS totalhours
FROM prepayhrstotals

Using the same methods of connecting to the database, how can I amend this code to write the result of a second query (which only returns a number) to a label?
i have a form that my i use to look up whether or not there is an email address in the database. i wrote a query with this basic structure:
select *
from table A, table B
where table A.email = "email" or table b = "email"
i though that would return all instances that the email occurred in either table. what i am getting back is a bunch of null or other unrelated records from table A with a matching email in table B. the thing is, these two tables primary key to join them. i thought i wouldnt need to do that though in this case.
here is the actually query i am using if it makes things more clear:
select lm.cemailaddr, lm.b1emailadd, b.emailaddr
When I run select *from sysfiles it gives below result.

View 2 RepliesI have a datatable in MS SQL that has FirstName and LastName. In MS SQL I created a computed field called FullName that was ((rtrim([LastName])+', ')+rtrim([FirstName])) I created a DataSet and a Business Logic Layer. In my typed DataSet I saw FullName in the listing when I created it. I am able to use FullName in my webpage. I use it to populate a dropdownlist. However, now when I make changes to the Customer Table I am getting this error message (seen below)
Question: Should I have created the field FullName in my MS SQL Table or should I have left it alone and somehow just added a column to the DataSet and placed an expression in the FullName column? The column "FullName" cannot be modified because it is either a computed column or is the result of a UNION operator.

I have stumbled into a problem in which Im having a hard time solving. I have a linq data setup(based on a mssql) where a Purchase Order contains a number Equipments - each equipment has a price. I have a gridview that shows the summed price of the equipments that are included in a Purchase Order. This sum is currently being calculated on RowDataBound through a "listOfEq.Sum(Eq => Eq.PurchaseOrderPrice);" expression which works without any problems. My problem is that I want to be able to sort the gridview based on this summed value, which I cannot do with a normal sortexpression. My next thought was to create a function in my database to calculate the sum instead and then use this is my data basis for the summed column. I have created a function like this:
[Code]....
I want to create a sortable column based on this data. My thought is something like this:
[Code]....
Displaying the correct information is not a problem, however creating the sorting is. Im not sure what to put in the SortExpression. Anybody got an idea of what to do? Perhaps I am forced to use a computed column for this however I dont know to create this column when its based on another table. If this is the case, any idea about how to do create a computed column thats based on data from another table?

View 3 RepliesI have the following GridView:
<asp:GridView ID="gv" AutoGenerateColumns="false" runat="server">
<Columns>
<asp:BoundField DataField="productName" HeaderText="Item" />
<asp:BoundField DataField="unitCost" HeaderText="Cost" DataFormatString="{0:c}" />
<asp:BoundField DataField="originalCount" ItemStyle-HorizontalAlign="Center" HeaderText="Old Count" />

<ItemTemplate>
<asp:TextBox ID="NewCount" Width="20" runat="server" />
</ItemTemplate>
</asp:TemplateField>

</asp:GridView>
And I want to add a final 'Total' column that calculates (originalCount - NewCount) * unitCost and updates it as the user enters a number in the NewCount text box. Can I do this just with .net, or do I need to use Java? If the latter, how do I tell which Gridview cell to update?

For context: First of all, I am new to LINQ, as I have been using SubSonic for quite some time now.
I have two tables, Users, and Affiliates. They both have a very typical schema. The FK that joins them is the UserId field, which is in the Affiliates table. I want to create a LINQ query that pulls the Username from the Users table using the AffiliateId value. The AffiliateId is a primary key of the Affiliates table.
I have tried to accomplish this using many variations of the following code:

In the above query, I expect to get a single row result set. However, I instead receive the entire table of results.
How can I make this work? I have yet to see an example or article out there to do what I am trying to do.
After looking for a driver to open legacy dbf drivers to connect, the next level trouble a have is this one: first, i can retrieve the data but when trying to filter by a parameter (somesc columns) i get an error. The error says about the database can't determine. The error is a columm tha is formated ( 1234 ) about 8 space, fixed. The values in the query appears like that. I resolve this by Trimming Ltrim(ColumnName) and i get this (1234). Now in SqlExpress, how can i filter by the new Trimmed Expression? (This is a primary key that the DBF use)
Sample:
SELECT column1, column2, column3
TABLE FoxProDB
Now
SELECT Ltrim(column1) as NewExp, column2, column3
TABLE FoxProDB
Where NewExpre = @NewExpres -Error-
Using vs2008 I have a SQL Server database attached to my web app. I want to use a computed time column in the database, along the lines of :
timenow is 1 column
hoursleft is another column
timeend would be another column.
I want timeend to = timenow + hoursleft. Is it possible to do that, and if so what would the formula be that I would enter into the computed column field, and, what datatype would the columns be, timenow and timeend I would expect to be time(7) and hoursleft an int. But is that correct?
I have a table of people with columns holding bits of info about them. I also need a variety of computed columns such as FileAs (lastname + ", " + firstname) and CityStateZip (you get the idea). I am wondering where best to put these definitions. It's worthwhile to note that the user will want to search for things as seen on the page, not the little atoms in the table. For example, searching on ", e" finds everyone whose first name begins with E. Typing ", az" to get everyone who lives in Arizona.
I noticed that linq-to-sql queries only recognize the fields in the table definitions, not any that are added in the partial class associated with the dbml. Linq-to-sql does work against computed columns in the database; however, the column definitions--especially for international address formats--will become very complex and much better handled in code.
I want to create a computed column in SQL SERVER and set the formula to this
([Category] + '.aspx?ID=' + [Post_ID])
Not working though......what am i missing? Category and Post_ID are current columns in the table
