And this is my code

View 1 RepliesI'm putting together a way to cull out bad emails from my table.
I have an email field, of course, and a 'fail' field (integer)

I am using Linq to SQL. I have a table with a uniqueidentifyer column.
I need to insert 1000 records, each with all the same values except for the uniqueid field.
I know the syntax to insert a single record for example where dc is a DataContext():
[Code]....
Does anyone know how if there is a way, other than looping 1000 times, to tell SQL to insert 1000 records generating different unique ids but assign the constant values to the other columns?
in which after changing the appropriate value if user clicks on "Save and Next" or "Save and Previous"
then by saving that particular record I have to move to the next or previous record respectively.
So in that record should be saved as well as it should display another record also in the screen.

I am having trouble with duplicate records. I tested .distinct() in several areas and nothing helps.
I got the search criteria from the PreviousPage. I then used this criteria to search QueryA.
I did a search using QueryA. I took the results, and put the IDs into an array.
I then did a search using QueryB, that matched the IDs in the array. QueryB is used for the ListView and to page records.
Using test records. QueryA results = 2 records. The array.length = 2. QueryB results = 3. ?
What am I doing wrong ?
Some of my Code:
myResults = (from r in QueryA
select r.ID).Distinct().ToArray();
totalrecords = myResults.Length; // = 2
using (ToHealthEN n = new ToHealthEN())
