Question

我在CrystalReport ASP.NET中遇到了一些麻烦。

我在ASP.NET中创建DataSet，我想使用ADO.NET（xml）将其导出到CrystalReport.rpt。但它失败了。当我创建新连接并在报表中放置属性列时，Crystal Report中的Main Report Viewer显示错误的结果。我在Oraclesqldevelop中编译了sql查询，结果很好，并没有任何问题。我想点击一个按钮并显示报告。

这是我的代码：

protected void btnsumbit_Click(object sender, EventArgs e)
{
    lblerror.Text = "";
    if (txtdari.Text == "" || txtdari.Text == null || txtsampai.Text == "" || txtsampai.Text == null)
    {
        lblerror.Text = "Tanggal Harus Diisi !!!";
    }
    else 
    {
        DateTime dt1 = Convert.ToDateTime(txtdari.Text);
        DateTime dt2 = Convert.ToDateTime(txtsampai.Text);
        if (dt1.Date > dt2.Date)
        {
            lblerror.Text = "Format Tanggal yang Dimasukkan Salah !!!";
        }
        else 
        {
            OracleConnection conn = new OracleConnection();
            conn.ConnectionString = connectionstring;
            conn.Open();
            string sql = "SELECT c.SUB_DISTRIBUTOR , c.MID  , c.REKNO , b.ID, b.TERMINAL_ID , b.TANGGAL , b.KETERANGAN , b.DEBIT , b.KREDIT , b.SALDO , b.REFF_NO,b.PRODUK,b.NO_PELANGGAN, b.SN_ID , b.STATUS from MERCHANT c JOIN DAILY b  ON (b.REKENING_NO = c.REKNO) where TANGGAL between TO_DATE('"+txtdari.Text+"','mm-dd-yyyy') AND TO_DATE('"+txtsampai.Text+"','mm-dd-yyyy')";
            OracleCommand cmd = new OracleCommand(sql, conn);
            OracleDataAdapter da = new OracleDataAdapter(cmd);
            DataTable dt = new DataTable();
            da.Fill(dt);
            da.Dispose();

            DataSet ds = new DataSet();
            ds.Tables.Add(dt);
            ds.WriteXmlSchema("C:\\Users\\Henz\\Documents\\Visual Studio 2012\\Projects\\LPI\\LPI\\Files\\Sample.xml");
            conn.Close();

            Response.Redirect("plot.aspx");
        } 
    }
}

根据您的描述，我可以理解没有发生任何错误。主要问题是你的结果不像你的期望。所以我认为你应该再次检查你的命令的参数。请尝试使用以下代码：

DateTime dt1 = Convert.ToDateTime(txtdari.Text);
DateTime dt2 = Convert.ToDateTime(txtsampai.Text);

////////ARI DATE/////////
OracleParameter fromDateParameter = new OracleParameter();
fromDateParameter.OracleDbType = OracleDbType.Date;
fromDateParameter.Value = dt1;

////////SAMPAI DATE/////////
OracleParameter toDateParameter = new OracleParameter();
toDateParameter.OracleDbType = OracleDbType.Date;
toDateParameter.Value = dt2;


this.oracleDataAdapter4.SelectCommand = new OracleCommand("SELECT c.SUB_DISTRIBUTOR , c.MID  , c.REKNO , b.ID, b.TERMINAL_ID , b.TANGGAL, b.KETERANGAN , b.DEBIT , b.KREDIT , b.SALDO , b.REFF_NO,b.PRODUK,b.NO_PELANGGAN,   b.SN_ID , b.STATUS from MERCHANT c JOIN DAILY b  ON (b.REKENING_NO = c.REKNO) where TANGGAL BETWEEN :fromDateParameter AND :fromDateParameter)”, conn);
OracleDataAdapter da = new OracleDataAdapter(cmd);


da.SelectCommand.Parameters.Add(fromDateParameter);           
da.SelectCommand.Parameters.Add(toDateParameter);  
DataTable dt = new DataTable();
da.Fill(dt);
