Dec 16, 2010Sql Table has 2 fields "id" and "name". Also "id" is the primary key with identity. I am using data adapter to fill data table "myTable". This brings id/name pairs form the database and fill "myTable".
[Code]....
Later I add new rows to "myTable".
[Code]....
and call dataadapter.Update(myTable). Dataadapter will add new rows to the database and the database will assign new id to each new ecord. StoredProcedure which actually insert new record, returns @@identity. How can I add this @@identity to myTable
[Code]....
Data Adapter insert new records reursively and each insert in the database causes @@identity to be returned. I want dataadapter to add @@identity to myTable.

Linq 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# - Putting Datatable Comma Separated Values In A String?
Feb 4, 2011My datatable consists of a column named "ID". The no. of values in this column varies.Sometimes this Datatable fetches 3 IDs in that ID column, sometimes 2. Now if for example, my datatable has three values as 1,2,3. What I want is to put these three values in a string and separate them by commas as folows:-
string test= "1,2,3";
If Datatable has 2 values, then string should be as follows:-
string test= "1,2";
I did try but in vain.
edit:-
DataTable dt=new DataTable;
dt = obj.GetIDs();
for (int i = 0; i < dt.Rows.Count; i++)
{
string test= "What should be here????";
}
edit 2
foreach(DataRow dr in dt.Rows)
{
string str = str + "," + Convert.ToString(dr("ID"));
}
@Rajeev ::Tried this..it says dr is a variable but used as a method. What's wrong?

View 3 RepliesC# - 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;
