Datatable select time in smalldatetime column

Question

I have a datatable with 4 columns and one of them is smalldatetime type. When I retrieve datatable from SQL base, I would like to query further through datatable, but only by a specific time. Is this possible?

I am tryin with something like this:

DataRow[] rows = dataset.Tables[0].Select("resStart = 'some date '" + myTime+"'");

and specifically I am trying to navigate through dates and times in datagrid so finally it dhould retreive one row by query like this

DataRow[] rows = dataset.Tables[0].Select("resStart = '" + myDate +" " + myTime+"'");

Answer 1

If you want to query your data within your sourceCode DataTable class supports method SELECT which allows you to filter your table according to a given condition. Check out MSDN for a detailed explanation.

string filterExpression = "YOUR_SMALLDATE_COLUMN > #1/1/00#";
DataRow[] rows = YOUR_DATATABLE_VAR.Select(filterExpression);

// eg. print out results - or rebind data etc.
for(int i = 0; i < rows.Length; i ++)
{
    Debug.WriteLine(rows[i]["ANY_COLUMN_NAME"]);
}

Of course, you may also change your select statement to the database and append a whereClause.
