DataTable Select and functions

[munglet]

In a DataTable Select() method can I wrap the column name with a sql
function like LOWER()? The manner in which I tried failed.

For example, the code below does a simple Select to get an array of
DataRows.

DataRow[] rows = this.dataSet.Tables["StringValues"].Select("Values =
'" + newValue + "'");

However, I want to do the query case insensitive so I tried this, but
it doesn't work:

DataRow[] rows =
this.dataSet.Tables["StringValues"].Select("Lower(Values) = '" +
newValue.ToLower() + "'");

How could I go about doing a case insensitive Select on a datatable?

Thanks.

M,

While the Select method does support some very basic expressions, that
kind of string manipulation is not supported. You will have to cycle
through the rows yourself and select the appropriate rows.

Hope this helps.
