hey
.NET 2.0
I have a datatable which consist of 3 columns (int, date, value). This
DataTable have 3 rows, the values of *the "date" *("date" column is of
datetime datatype) column is:
2007-09-15 00:00:00.000
2007-10-15 00:00:00.000
2007-11-15 00:00:00.000
The problem is that when I my code try to select an record, I get no
records.
This is the select I try:
DataTable.Select("date >= '01.11.2007 00:00:00' *and date < '01.12..2007
00:00:00'");
this gives me 0 row, it should have given me 1 row
and this:
DataTable.Select("date >= '01.11.2007 00:00:00'");
gives me 3 rows, but it should have given me 1 row
what am I doing wrong here?
Well, this works for me:
DataSet data = new DataSet();
data.Tables.Add(new DataTable());
data.Tables[0].Columns.Add("ADate", Type.GetType("System.DateTime"));
data.Tables[0].Rows.Add(new object[]{DateTime.Parse("15/09/2007")});
data.Tables[0].Rows.Add(new object[]{DateTime.Parse("15/10/2007")});
data.Tables[0].Rows.Add(new object[]{DateTime.Parse("15/11/2007")});
DataRow[] rows = data.Tables[0].Select("ADate >= '01/11/2007' and
ADate < '01/12/2007'");
Console.WriteLine(rows.Length.ToString()); //returns 1
rows = data.Tables[0].Select("ADate '01/11/2007'");
Console.WriteLine(rows.Length.ToString()); //returns 1
but
DataSet data = new DataSet();
data.Tables.Add(new DataTable());
data.Tables[0].Columns.Add("ADate", Type.GetType("System.DateTime"));
data.Tables[0].Rows.Add(new object[]{DateTime.Parse("15/09/2007")});
data.Tables[0].Rows.Add(new object[]{DateTime.Parse("15/10/2007")});
data.Tables[0].Rows.Add(new object[]{DateTime.Parse("15/11/2007")});
DataRow[] rows = data.Tables[0].Select("ADate >= '11/01/2007' and
ADate < '12/01/2007'");
Console.WriteLine(rows.Length.ToString()); //returns 0
rows = data.Tables[0].Select("ADate '11/01/2007'");
Console.WriteLine(rows.Length.ToString()); //returns 3
gives the results you get. Your dates are being interpreted as MM/DD
not DD/MM.
