Compare two Dates in SQL Server

The below QUERY can compare two dates in sql server. In that query CONVERT() function is exist. Date value is changed into varchar data type by using CONVERT() function . Here we change the DATETIME data type into varchar. So we got exact date alone. The query as follows....

SELECT *
FROM Login_Attendance
WHERE (DATEDIFF(day, CONVERT(varchar(10), currdate, 101), CONVERT(varchar(10), '4/25/2008', 101)) = 0)

Here,

101----> denotes the required format(mm/dd/yyyy) of the date

For eg:
currdate='4/25/2008 2:23:34 PM'

Adding Empty Row to a Data Grid

Here we are going to see how to add empty row in a datagrid. First create an empty Data Row for a Data Table. Assign the Datatable as dataSource for the datagrid. Then bind the datagrid. Code is in VB.Net to add empty row is as follows.

#VB.NET

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim dt as new DataTable
Dim dr as DataRow
dr = dt.NewRow()
DataGrid1.DataSource = dt
DataGRid1.DataBind()

End Sub
