View 6 RepliesLinq To DataTable Not Producing Distinct Values?
Oct 19, 2010I have a datatable which has been dynamically generated from FoxPro tables using a UNION Select statement. e.g.
SELECT * FROM x UNION SELECT * FROM y UNION SELECT * FROM Z ORDER By v_alue1
This produces a datatable with about 100 rows, each containing many fields, one of which is c_olor. From this datatable, I would like to select the distinct colors and then output in a dropdown.
I have a public class Color which just has one property which I can then use as the DataTextField and DataValueField for the dropdownlist
[code]...
However this never results in the distinct colors.
I have searched and searched for what I am looking for, and this seems to be one of the methods to produce a distinct set of results, but this and the others do not work.
My reasoning behind getting the colors this way, is that I need to get various other distinct values from the same UNION SELECT datasource, so would just do one DB call, cache the results, and then just used this cached datasource to retrieve all my distinct values.

C# - Order Datatable By Relevance Using Linq By Column Values Which Are Comma Sperated?
Aug 31, 2010I have a Datatable that contains a column called Tags, Tags can have values such as
row[0] = Tag1
row[1] = Tag1, Tag2
row[2] = Tag2, Tag3
row[3] = Tag1, Tag2, Tag3
row[4] = Tag4, Tag6
and are seperated by comma's etc..
I have the value of Tags for the current document and have run a query to select all other documents that have either of the Tags in there row. for example lets say the current document Tags are (Tag1, Tag2, Tag3)
so from the example rows above all the rows above are returned apart from row[4] Here is the bit i'm lost with, i now want to sort the datatable by how many tags are matched with the current document. so for the example i've talked about so far they should be ordered
row[3] = Tag1, Tag2, Tag3
row[1] = Tag1, Tag2
row[2] = Tag2, Tag3
row[0] = Tag1
Not used linq before but was told it could do this. so far i have
var query = from c in dt.AsEnumerable()
orderby c.Field<string>("Tags").CompareTo(dr["Tags"]) ascending
select c;
C# - How To Get Distinct Records In Datatable
Jul 20, 2010I am using C# + VSTS 2008 + .Net + ASP.Net + IIS 7.0 + ADO.Net + SQL Server 2008. I have a ADO.Net datatable object, and I want to filter out duplicate/similar records (in my specific rule to judge whether records are duplicate/similar -- if record/row has the same value for a string column, I will treat them as duplicate/similar records), and only keep one of such duplicate/similar records.
The output needs to be a datatable, may output the same datatable object if filter operation could be operated on the same datatable object.
What is the most efficient solution?

View 6 RepliesUsing Select Distinct On An Already Created DataTable Object?
Nov 16, 2010I have an already created DataTable object which i am using for my girdview (asp.net) i also need to bind a column of that object to a DropDownList. The datatable has the correct details in the column but the column contains more that 1 of the same name in the column - hence I would love to just do some kind of SELECT DISTINCT on the datatable and copy it to a new datatable for use with binding the dropdown.
This would allow me to save resources by making another trip to the database.
Here is an example, the current datatable has a column called items and in this column has the following entries
1
1
1
1
5
5
6
And of course i need only unique items for binding to my dropdown, hence i need the following data
1
5
6
Of course i don't want to change the original datatable object but rather make a copy of it will the new details.

SQL Server :: Selecting Distinct Keys With Highest Value In Another Column?
Sep 25, 2010I have a table with 2 columns that lookes something like this:
ChapterID | VersionNumber | VersionID |
1001 | 1 | 1004 |
1001 | 2 | 1005 |
1002 | 1 | 1006 |
1002 | 2 | 1007 |
1002 | 3 | 1008 |
1003 | 1 | 1009 |
1004 | 1 | 1010 |
what I wanna achieve is to have a statement that selects distinct uniqueid's from the chapterID field and with every duplicate I would like to have the record with the highest version number
Below is the result I would like to achieve:
ChapterID | VersionNumber | VersionID |
1001 | 2 | 1005 |
1002 | 3 | 1008 |
1003 | 1 | 1009 |
1004 | 1 | 1010 |
I have tried this statement:
Select Distinct ChapterID, max(VersionNumber) from Versions groupby ChapterID
and it works fine, but when I add the VersionID column like so:
Select Distinct ChapterID, VersionID, max(VersionNumber) from Versions group by ChapterID
it returns an error.

View 4 RepliesADO.NET :: Linq To Sql Using Distinct On Individual Values?
Jul 29, 2010I have a database that is filled with documents. In the database there is the documents id, name and version. Two documents can have the same name and id but are seperated by different versions.For instance there can be two entries, id: A44, name: Dilbert was here. But they are version A and B.When retrieving these to a listview I wish to limit the documents shown to only one version. Doing so means that I am only to show one document with the same id. I only get the id and name to show in the listview so I thought that distinct might do the trick. But since the name can change throughout different versions this was no good.Basically I wish to retrieve all documents but with distinct id. How do I achieve this?

Select Distinct And Include Non-distinct Columns?
Apr 20, 2010I would like to select a distinct query based on three fields and display the rest of the fields. For example,
I have firstname, lastname, address, city, state and zip, but I only want to use the distinct on these fields first and last name. However when i use the distinct function I get a distinct on all the selected rows. I just want to distinct firstname and lastname and display the other fields. for example,
Mary Smith New York
Mary Smithy New York
Mary Smith Maine
I would like the result to be:
Mary Smith New York
Mary Smithy New York
I don't care about Mary Smith Maine, because i am only using the distinct for "Mary Smith" firstname and last name and showing the city.
