I m doing a project in VB.Net in which i ve to do sampling of records with replacement.
and then i ve to show the detail record of that selected sample in grid.

I can select the sample by query and make its string with all those repeated ID's.

After that i use that string in DetailRecordQuery in Where clause like
"Where ID in(string of ids)" the record shows are of distict ids.
