Which db you are using? And you are asking 100 records, meant based on some condition or top 100?
Improve your question.

He is talking about datatable. This question has nothing to do with db.

using framework 2.0, its like navigating through records, 100 records first, then next 100....so on

Solution 2

Try lambda expression:

C#

Datatable1.AsEnumerable().Where(s=>s.Field<stirng>("SomeColumn") == "SomeValue").CopyToDataTable(Datatable2, LoadOption.Upsert);
//Here Datatable1 is having 1000 records(assume), and you are copying the datatable to Datatable2
</stirng>

[Update]
Then how about this?

C#

DataRow[] dr = DataTable1.Select("ColumnName='columnvalue'");

and then:

C#

foreach (DataRow row in dr ) {
   DataTable2.ImportRow(row);
}

dont want to use loop

A loop is required to add the rows in DataTable in Net Framework 2.0.
