Question

尝试使用WPF从Oracle数据库中选择记录时遇到问题。我收到此错误：ORA-01830（日期格式图片在转换整个输入字符串之前结束原因）

我的代码：

OracleDataReader dr;
OracleCommand cmd = new OracleCommand();

using (OracleConnection cn = new OracleConnection() { ConnectionString = "DATA SOURCE=*****:1521/ORCL;PASSWORD=*****;PERSIST SECURITY INFO=True;USER ID=*****" })
{
    cn.Open();

    // DateTime dt = Convert.ToDateTime(from_datePicker.Text);
    OracleDataAdapter da = new OracleDataAdapter("Select B_NO,R_CLIENT_NAME,ENG_NAME,USER_NAME,R_ADDRESS,R_WORK_DATE,B_DATE,B_YEAR,B_WP_NAME,I_NAME,I_NO,BI_Q,I_CONTSR_TYPE_DESCR,R_PLACE_DESCR from VW_CI_REP_ITEMS_RESERV  where R_WORK_DATE = '" + from_datePicker.SelectedDate + "'", cn);

    DataSet ds2 = new DataSet();
    da.Fill(ds2, "VW_CI_REP_ITEMS_RESERV");

    DeltaInvoices_Grid.ItemsSource = ds2.Tables["VW_CI_REP_ITEMS_RESERV"].DefaultView;
}

GridCount_txt.Text = DeltaInvoices_Grid.Items.Count.ToString();

Answer 1

遇到ORA-01830错误时，将出现以下错误消息：

ORA-01830：日期格式图片在转换整个输入字符串之前结束原因您尝试输入日期值，但是输入的日期与日期格式不匹配。

我认为您应该像这样将传递给oracle数据适配器的“日期”字段转换为：

 TO_DATE(from_datePicker.SelectedDate, 'dd-mon-yyyy hh:mi PM')

或您已将此字段保存在数据库中的任何其他格式。

尝试

      OracleDataReader dr;
      using (OracleConnection cn = new OracleConnection() { ConnectionString = "DATA SOURCE=*****:1521/ORCL;PASSWORD=*****;PERSIST SECURITY INFO=True;USER ID=*****" })
      {
        cn.Open();

        var sql =
          "Select B_NO,R_CLIENT_NAME,ENG_NAME,USER_NAME,R_ADDRESS,R_WORK_DATE,B_DATE,B_YEAR,B_WP_NAME,I_NAME,I_NO,BI_Q,I_CONTSR_TYPE_DESCR,R_PLACE_DESCR from VW_CI_REP_ITEMS_RESERV  where R_WORK_DATE = :fromDatePicker";

        OracleCommand cmd = new OracleCommand(sql, cn);
        var parameter = new OracleParameter("fromDatePicker", OracleDbType.Date) {
          Value = Convert.ToDateTime(from_datePicker.Text),

        };

        cmd.Parameters.Add(parameter);

        OracleDataAdapter da = new OracleDataAdapter(cmd);

        DataSet ds2 = new DataSet();
        da.Fill(ds2, "VW_CI_REP_ITEMS_RESERV");

        DeltaInvoices_Grid.ItemsSource = ds2.Tables["VW_CI_REP_ITEMS_RESERV"].DefaultView;
      }

      GridCount_txt.Text = DeltaInvoices_Grid.Items.Count.ToString();
