สอบถามเรื่องการค้นหา เดือน/ปี (datetime) จากฐานข้อมูล sql server

Dim dt As New DateTime(MyYear, MyMonth, 1)
Dim datetimeSearch As String = String.Format("{0:M/yyyy}", dt)

Dim dt As New DateTime(MyYear, MyMonth, 1)
Dim sql As String = "SELECT RIGHT(CONVERT(NVARCHAR(10), MyDate, 103), 7) AS MonthYear FROM MyTable WHERE YEAR(MyDate) = @Year AND MONTH(MyMonth) = @Month"

Using cmd As SqlCommand = con.CreateCommand()
   cmd.CommandType = CommandType.Text
   cmd.CommandText = sql
   cmd.Parameters.AddWithValue("@Year", dt.Year)
   cmd.Parameters.AddWithValue("@Month", dt.Month)
   ...
   ...
   ...
End Using
