SQL Server :: Is There An Alter Statement To Rename A Column Name
Feb 15, 2011Is there an alter statement to rename a column name? Maybe dropping and adding a new column is the only possible way -- or so I thought?

Forms Data Controls :: Dynamically Alter The Page Size In A Paged Gridview Based On Data In A Particular Column?
Dec 14, 2010I've already searched to no avail for an answer to this question:is it possible to dynamically alter the page size in a paged gridview based on data in a particular column?In other words,let's say I get data from a table that lists students enrolled in a particular course.If there are 10 students in Course "A," then I want page 1 in my gridview to show 10 records.
If there are 15 students in Course "B," then I want page 2 in my gridview to show those 15 records,and so on.I imagine that this could probably be done with a master-detail kind of set up,but let's say for the sake of argument that I don't want to go that route.

DataSource Controls :: Multiplying Column Values On Insert Statement?
Jun 6, 2010This is my code so far:
SQL = "insert into " & tableNameToday _

& "Fat, Of_Which_Saturated, Of_Which_Monounsaturates, Of_Which_Polyunsaturates," _

how do i multiply the columns like this. for now static explanation would be ok but eventually i would like to make it dynamic so there would be a text box for users to enter the amout they like e.g 160g then the table would know to multiply the columns by 1.6.

SQL Server :: Getting An ERD From A Statement ?
Jan 15, 2011At University it was suggested to us that the best way to learn about designing and implementing databases is to practice the art. So I chose the following statement to implement and refine my skills:
Harpers Hauliers deliver shipments on contract for customers. Each contract is identified by a unique contract number. The contract may require a single or many shipments. Each shipment must be allocated resources of a vehicle (regisatration number, type, volume, weight), which is suitable for the shipment and a driver (name, address, telephone number) who is licensed to drive that type of vehicle.
As soon as a customer (companyname, address, telephone number) makes an enquiry, a pending contract is set up. The contract is then negotiated on price between the customer and the haulier. Not all pending contracts are successfully negotiated. Either the customer or the haulier may back out at this stage. If the haulier has previously carried for this customer and financial settlements were not made to his satisfaction, he may reject the contract. He may also reject the contract on the basis that he thinks the workload being undertaken is too big a risk for his company with this customer that is the contract is worth more than he is willing to risk for this customer.
An agreed contract requires the haulier to deliver the listed shipments between a start and an end date, at an agreed price. The haulier always takes out an insurance policy on the contract, in case he cannot allocate enough resources to the contract to get it delivered on time.For each shipment in the delivery there is an origin and destination. The shipment has a description, a weight and a volume. The haulier has a fleet of vehicles of different types and a staff of drivers with different license types, to match the vehicle types. During the contract, the haulier tries to allocate vehicle, driver and time-slot resources to each ship-ment. The vehicle must have a suitable volume and weight capacity and the driver must have a suitable license to drive that vehicle.
The time must be when the driver and vehicle are free and before the contract end date. As each shipment is delivered, it is marked off as delivered by the driver, giving the date and time of delivery. If not all shipments are delivered by the contract end date, the con-tract becomes overdue, incurring a penalty cost on the haulier. When all shipments are delivered, the haulier invoices the customer for the required amount. Each invoice is has a date and is identified by a unique invoice number . Payment from the customer may be in full or may be partial. The contract is kept active until all payments have been made against it.
And here is the ERD that I have come up with. I have created the ERD in Visio 2010.

Can someone who's an expert in Database design kindly check my ERD and see if it perfectly matches the Problem Statement.
SQL Server :: Invalid Column Name - Column Is Not Referenced Anywhere?
Aug 18, 2010I have a SQL Server 2005 database which is queried by a web service which is called by an aspx page.
I inherited a messy and inefficient project, and I was working on cleaning up a GridView by making it dynamic and by having consistent field names in the database when I started getting an error of - Sys.WebForms.PageRequestManagerServerErrorException: Invalid column name: 'ASSIGNED_TO'
Assigned_to does not exist in the database, in the web service, or in the website solutions in any place. It was the name of one of the fields in one table, which I changed to USERID so that either of two datasets would fit into a Gridview (all other fields were the same). I then replaced all references of ASSIGNED_TO with USERID, which is when the issues began. The first of the two queries below causes the exception to be thrown, but the second one does not. I have tested both with the WCF Client and with a query within SQL Server to verify that they do work, so the issue has to be on the website side.
sSQL = "select distinct B.BADGE_NBR, a.REGId,B.CYC_RTE, b.USERID, a.MTRREAD,A.NEWMTRNUM, a.COMPTIME, B.FA_TYPE, CASE WHEN A.MTRCOMMENTS <> 'Null' THEN '*' END as Comment,a.MTRLAT,a.MTRLONG,a.WOFAID, b.ADDRESS, a.MTRREADFLAG, b.ROUT_SEQ from MobileDataReturn a,WORKORDERDIPATCHFILL b Where a.RegId = b.REGID and a.WOFAID = b.FA_ID and B.CYC_RTE " & route & "' and b.USERID " & worker & "' and B.BADGE_NBR " & badge & "' and a.MTRREADFLAG " & readflag & "' and b.FA_TYPE " & fatype & "' Order by a.COMPTIME desc"

SQL Server :: Where Is Statement In XML Explicit
Dec 27, 2010I've build a query, but the where statement is doing strange things. First my query:
select * from
(
SELECT 1 as Tag, null as Parent, row_number() OVER (ORDER BY tblOccasion.ID DESC) AS [tblOccasion!1!rownum], FROM tblOccasionwhere tblOccasion.UserID = @UserName and ((tblOccasion.MerkDesc like '%' + @search + '%')or(tblOccasion.UitvoeringDesc like '%' + @search + '%')or(tblOccasion.UitvoeringDesc like '%' + @search + '%'))
) AS A where a.[tblOccasion!1!rownum] BETWEEN (@startRowIndex) AND (@startRowIndex+@pageSize)
order by a.[tblOccasion!1!MerkDesc!Element],a.[tblOccasion!1!TypeDesc!Element],a.[tblOccasion!1!UitvoeringDesc!Element]
FOR XML EXPLICIT;
But the result should be ordered by Merkdesc, then TypeDesc, and then as last the uitvoeringDesc.
So for testing i only used the MerkDesc. The strange thing is that i get the result:
BMW
BMW
BMW
Opel
Volvo
But this was page 1, on page 2 (paging) you got BMW again... so he takes the first 5 rows ore something and then the order. But i like that he first orders it by MerkDesc and then picks the first 5. How can i change that, i can't add a Order by in the inline sql statement i get this error: Msg 1033, Level 15, State 1, Procedure MijnAdvertenties, Line 47 De ORDER BY-component is ongeldig in weergaven, in line functies, afgeleide tabellen en algemene tabelexpressies, tenzij ook TOP of FOR XML is opgegeven.
