Get latest date record - SQL query

2008/07/19 19:21

To return the latest record (one record only) from data base table where one of the fields is in Date/Time format:

SELECT TOP 1 * FROM table_name ORDER BY date_time_column_name DESC


* for ORACLE instead of TOP 1,  ROWNUM shall be used

* the query may return NULL value - suitable exception handling must be provided

Programming in C# using data binding and data view

DataView dv = new DataView(DataSet_name.table_name);

string sort = "Date_column_name DESC";

dv.Sort = sort;

DateTime rdt;

if (dv.Count > 0) rdt = Convert.ToDateTime(dv[0]["Date_column_name"]);

Do not forget to fill the corresponding table adapters before creating data view.


and only then


DataView dv = new DataView(DataSet_name.table_name);
