    C#NET Sql striing using Date Between

    Hullo Good Friends,
    I need your help. Please Help me. Thank You.

    I encounter a very interesting problem regarding Window Application using C#NET3.5, SqlServer2000 with SQL string using Where Statement with DATE BETWEEN statements

    I am using date parameters from 2 input textbox to retrieve Customer Invoice table to fill the DataGridView and it’s not working as the problem seem
    to be caused my the
    SQL String Statement : OrderDate Between DateFrom and DateTo


    Error message:
    The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value


    private void FFillDataGridView()
    {
    DateTime DateFrom =Convert.ToDateTime(this.txtDateFrom.Text);<-causing error
    DateTime DateTo =Convert.ToDateTime(this.txtDateTo.Text); <- causing errror message
    string strsql = " Select OrderID, ProductID, ";
    strsql += " Convert(varchar(10), OrderDate, 103) as [OrderDate], ";
    strsql += " Convert(Numeric(10,2), unitprice, 2) as [UnitPrice], ";
    strsql += " From tblInvoices ";
    strsql += " Where (CustomerID = '" + strCustID + "')";
    strsql += " AND (OrderDate between DateFrom + "'"; <-- not working
    strsql += " AND '" + DateTo + "')"; <-- not working

    try
    {
    sqlconn = new SqlConnection(connstr);
    sqlconn.Open();
    DA = new SqlDataAdapter(strsql, sqlconn);
    DS = new System.Data.DataSet();
    DS.Clear();
    DA.Fill(DS, "Invoice");
    this.dataGridView1.DataSource = DS.Tables["Invoice"];
    }
    Catch (Exceptional Ex)
    {
    messagebox.show(ex.message);
    }
    }

    Thank you for helping me.
    Cheerws,
    Lennie

    Re: C#NET Sql striing using Date Between

    you need to concatinate DateFrom to the string. plus, you missed a ' character in the beginning of the date.
    try this:
    Code:
    //...
    strsql += " AND (OrderDate BETWEEN '" + DateFrom + "'";
    strsql += " AND '" + DateTo + "')";
    by the way, you might want to consider using parameters instead of concatenating values.

    Use DateTime.Parse() instead of Convert.ToDateTime().
