SQL Server :: How To Remove Rows For Duplicate Field Values
Oct 18, 2010
suppose I am having sample table like below.
I need to remove duplicate orderid's and i need all column names also while doing query.
note that rows are not in the order. Order will be like this only.
I am able to get the records which are duplicated but not able to delete further.
In this case how to delete?
My consideration is that only distinct orderid's should be there in the table. Not bothering about the which orderid row is being deleted.
name orderid destination
a 1 aaa
d 2 ddd
b 1 bbb
f 3 fff
e 2 eee
g 4 ggg
h 3 hhh
c 1 ccc

I have a master table relationship, i.e. depending on what is selected in the dropdown list the grid show the relevant data.In the database there are several identical entries for the Position field, for instance there are four marketing managers that have different name. How can i group the identical Position name in the dropdown and when selected the grid should display all marketing managers. Here is the code:
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="sqlDdl"
DataTextField="ID" DataValueField="Postion">
</asp:DropDownList>
<asp:GridView ID="grid" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID" DataSourceID="sqlCon" EnableModelValidation="True">

I have 2 divs with 2 nested divs in them. Let's say div1 contains div11 and div12 and div2 can also contain div11 and div12. I know that this is not normally allowed but I am using jTemplates and they do allow you to print the div11 and div12 twice or more on the same page. The HTML looks like this:
<DIV1>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
</DIV1>
<DIV2>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
</DIV2>
How do I ensure that I only have one div with the unique ID loaded on the page, so I don't get in any duplicate DIVs. The result should look like this:
<DIV1>
<DIV11>Some text</DIV11>
<DIV12>Some text</DIV12>
</DIV1>
<DIV2>
Some other text
</DIV2>
Is there any way to check for a duplicate ID in either jQuery/javascript language and remove all but one using each or some other method?

I have a linq statement that retrieves several rows from a stored procedure and maps them to a custom class. The rows returned could contain mulitple instances of the same ID
eg
id date total
1 01/01/2011 3
2 01/02/2011 2
3 02/03/2011 5
1 01/01/2011 3
the stored procedure perfoms some complex calculations to return the data How can I remove the duplicate rows in the list ive returned? Ive tried distinct but it doesnt work I want to process the RETURNED list (as there are only 4 rows here, i want to end up with 3) and just have 1 instance of ID 1.

removing duplicate rows from datatable or (dataset) by columnd ID (unique). Below function is working but I would like to edit/adjust the remaing (former) duplicate row's value, not the ID value btw.
Example:
ID name sport
-------------------------------
356 John Football
357 Johny Hockey
357 Johny Hockey
358 mike Soccer
should be:
ID name sport
--------------------------------------------------------------
356 John Football
357 Johny newFoo Hockey
358 mike Soccer
Public Function RemoveDuplicateRows(ByVal dTable As DataTable, ByVal colName As String) As DataTable
Dim hTable As New Hashtable()
Dim duplicateList As New ArrayList()
For Each drow__1 As DataRow In dTable.Rows
If hTable.Contains(drow__1(colName)) Then
duplicateList.Add(drow__1)
Else
hTable.Add(drow__1(colName), String.Empty)
End If
Next
For Each dRow__2 As DataRow In duplicateList
dTable.Rows.Remove(dRow__2)
Next
Return dTable
End Function

I have a property table and an image table.
I want this query to return all distinct properties and a thumbnail image. However some properties don't have thumbnail images and they don't get returned by the query. If the imgid is null I still want to return the property. Not sure of how to do this.

The rows might look like this:

Within my stored procedure I have a piece of SQL that is supposed to remove from a temporary table, any values that are not set to '1' for a particular field, but this does not work as required.
The SQL in question looks like this:
[CODE]
[code].....
Can you see what I have done wrong here , as the test for tab3.THIS_VALUE = 1 is returning results for THIS_VALUE = 0 also, but all I want is a table that has values with THIS_VALUE = 1 only.

I'm new to ASP.NET MVC and I'm trying to implement an address manager.I'm using Linq2Entity Framework. I've got a table with contacts and one with phone numbers. These two tables are linked by a contact_has_phone_number table. The Entity Framework enables me to get all phone numbers that are assigned to one contact. This is done by calling contact.PhoneNumbers which returns a collection of phone numbers.

an attribute or some other setting. I am exporting the contents of a gridview to an excel spreadsheet. And for the most part it works great, with one minor annoyance, the export duplicates the entire gridview. In other words this is what I get:
Col1 | Col2 | Col3 | Etc | Col1 | Col2 | Col3 | Etc |
Code:
The GridView ASPX
<asp:GridView ID="GridViewList" runat="server"
BackColor="White" BorderColor="#E7E7FF" BorderStyle="Solid"
BorderWidth="1px" CellPadding="3" Width="100%" Font-Size="8pt"

I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List??
WHich one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
My XML will be like this
<root>
<Customer>
<CustomerID>GUID1</CustomerID>
<CustomerID>GUID2</CustomerID>
<CustomerID>GUID3</CustomerID>.....

I have 5 tables as follows
as it can be seen from diagram, I have one table ie.patientdetails with Pid as primary key and other 4 tables have pid which is foreign key related to Pid in patient details.
the problem is that when if a test data is filled for say patient with Pid as 1, the data is saved nicely in required tables
If i try doing that again for same patient then a duplicate is created in test tables with pid as 1.
