Hi Folks,

I do have a search string, and I need to display the words similar to that search string from a particular Oracle DataTable.

I am able to do that but since the search is through the entire
DataTable it's time consuming, thus creating a performance issue.
Please suggest how do I go for it...

If you are searching only in one field, just use standard SQL command:

SELECT myfield FROM mytable WHERE criteria=searchstring;

If you are searching on the whole row, try this:

using System.Data;
using System.Linq;

// this is for single result, would return null if no result
DataRow result = (from DataRow r in tableVariable.Rows
where string.Join(",", r.ItemArray).Contains(searchString)
select r).FirstOrDefault();

// and this is for many result
List<DataRow> results = (from DataRow r in tableVariable.Rows
where string.Join(",", r.ItemArray).Contains(searchString)
select r).ToList();

Haven't tried it though, but I think it is an fast and effective way (not time-consuming).
