I'd like to use sql to select top (#) random row into another table, but it inserts the same record a few times sometimes. I want to avoid duplicates to be inserted, what shall I do?
what I've got for now is
INSERT INTO CompWin (PrizeID, EntryID, UserID) SELECT TOP (50) PrizeID, EntryID, UserID FROM CompEntry ORDER BY NEWID()
i want to select three records order by Date .This is my News table.
NewID NewTitle NewContent NewDate
1 Example ExampleContent 01.12.2010
2 Example2 ExampleContent2 02.12.2010
3 Example3 ExampleContent3 03.12.2010
4 Example4 ExampleContent4 04.12.2010
So,query selects example4,example3 and example2.
I've got a sp as below:
The functionality I want to achieve is that when isHomePageFeatured is checked then this record is set to 1 for that column and for all the other records in the table it is set to 0.
This is fine for update as I can use the property Id to compare against, but for the newly inserted record it doesn't yet have a propertyId so I wondered if using newID() to affect all other records would have the same affect.

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?

Is there any way to make sure an Insert Command happens before the Page_Load Events? I'm having a problem with inserting, then reading the DataSet directly after. It seems it processes too quickly, or prior to the record being inserted. It has an impact on the DataSet that is to be displayed on screen. Summary:
Page_Loads > Finds Saved Data > If None exists (string contains 2 types of matches) > Displays the 1 of 2 types randomly.
Buttons 1 & 2 Insert their respective options > Page Posts Back > Page_Loads > Read Saved Data > If my Max amount of the 1 of 2 types of Data are reached, the remaining type is shown > Displayed on page The problem I am having is that my DisplayDataSet is not getting the correct values. It seems it's always 1 record behind on the count, because the count happens so fast, it's not getting the record that was just inserted. How can I write this, or make sure the "Find Saved Data' Routine happens after the Insert has been preformed?

I have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."

I am working on a project in .NET (C#), connected with a database. And I am entering values in database through 'text-box' control, for a part of the project. What I want is to check if the user entering value already exsists in the database and if so, shows error during that time only.
I have searched for any familiar post here, that could solve my query, but didn't get any.
my EXACT objective(if not cleared earlier):-
when the user enter the value in
textbox, automatically an event to
check any duplicate records in
database should occur. And if found,
displays an error message
On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value.
Then if user will provide some other telephone number then he allows to insert record.
For insertion of record I used ObjectdataSource.
User will enter telephone number in a simple textbox.
I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit.
I have a pre-existing app that allows me to display detailed record results from a database,and I've made a custom mod to it to limit the type of results(i.e. show me just THESE three tables instead of all tables associated with a record).I would like to make a hyperlink from the abridged version of the record to the full version of the record,but I can't for the life of me figure out how to do this!I know that the code in the .aspx file should look something akin to:
<asp:HyperLink ID="hyp1" runat="server" NavigateURL="http://server/file.aspx?d=" text="Full Report" target="_blank" />
I need to be able to insert a record ID in order to get the end-user to the appropriate results page,so I need to find a way to insert a field Record_ID at the end of that keyword string call (d=).
Any ideas of what I'm doing wrong and/or what I need to do to the code behind file?
I'm sure that this is one of those "can be done in 5 minutes" types of things once I know what I'm doing.
in my table data are stored many times ...I want select the only one data from the repeated data
select ven.Id,ven.Vendor_Name from Purchase_Requsition pur,Item_master itm,Approved_Vendors ven where itm.Item_Id=pur.Item_masterItem_Id and ven.Id=itm.Approved_VendorsId and pur.Request_StatusId=1 and pur.StatusId<>4
ID VENDOR_NAME
1 Ranbaxy
1 Ranbaxy

ID VENDOR_NAME
1 Ranbaxy
2 cipla
My query was SELECT ID FROM TBLCARS WHERE (ID IN (1, 5, 3, 6))
this will usualy produces the result 1,3,5,6 order.But i want the result in the specefied order of ids.ie:1,5,3,6;ie;first get the row with id 1,then with id 5,then id 3,and last 6.
