Question

我试图调用一个过程，并使用在代码中执行后得到的值。

我创建了一个过程Getdata，并从ASP.NET MVC中调用它并尝试使用它。

Oracle过程：

    CREATE OR REPLACE PROCEDURE Getdata(v_hr_stk_out out number,v_cr_stk_out out number) Is
    r_stk  number;
    vr_stk number;
    BEGIN
    select round(sum(a.batch_wt)) into r_stk from dbprod.sm_data a where a.iss_date is null and a.cw_coil_no is not null and a.prod_cd = '37' and a.from_plant != a.hsource;
    select round(sum(a.batch_wt)) into vr_stk  from dbprod.psm_data a where a.iss_date is null and a.cw_coil_no is not null and a.prod_cd = 'C9' and a.from_plant != a.hr_source;
v_hr_stk_out:=v_hr_stk;
v_cr_stk_out :=v_cr_stk;
    END;

ASP.NET MVC端：

 OracleConnection conn = new OracleConnection(ConfigurationManager.ConnectionStrings["Mycon"].ToString());
 conn.Open();

 OracleCommand command = new OracleCommand();
 command.Connection = conn;
 command.CommandText = "Getdata";
 command.CommandType = CommandType.StoredProcedure;

 OracleDataAdapter adapter = new OracleDataAdapter(command);

 DataSet dataSet = new DataSet();
 adapter.Fill(dataSet);

 conn.Close();
 return View("Home",dataSet);

绑定值在视图中

@using System.Data;
@model DataSet
    <table cellpadding="0" cellspacing="0">
        <tr>
            <th>A</th>
            <th>B/th>
            <th>C</th>        
        </tr>
        @foreach (DataRow row in Model.Tables[0].Rows)
        {
            <tr>
                <td>F</td>
                <td>Dataset.Tables[0]</td>
                <td>Dataset.Tables[1]</td>            
            </tr>
        }
    </table>

过程中的值应该出现并绑定到视图的相应列中。

当前，调用adapter.Fill(dataSet);后数据集中没有存储任何值。

我是ASP.NET MVC和Oracle的新手。任何想法将不胜感激

Answer 1

在ADO.Net中使用填充数据集时，需要使用Ref Cursors获取数据

将您的过程更改为

<div class="parent">
  <div class="child">
    <input class="detail" placeholder="click into input">
    <input class="detail" placeholder="click into input">
    <input class="detail" placeholder="click into input">
  </div>
</div>

<div class="parent">
  <div class="child">
    <input class="detail" placeholder="click into input">
    <input class="detail" placeholder="click into input">
  </div>
</div>

<div class="parent">
  <div class="child">
    <input class="detail" placeholder="click into input">
  </div>
</div>

<button id="select-detail">Select all details of nearest parent to cursor position (open inspector to check)</button>

对于C＃，请遵循此link

更新

 CREATE OR REPLACE PROCEDURE Getdata(v_hr_stk_out OUT SYS_REFCURSOR) Is
r_stk  number;
vr_stk number;
BEGIN
select round(sum(a.batch_wt)) into r_stk from dbprod.sm_data a where a.iss_date is null and a.cw_coil_no is not null and a.prod_cd = '37' and a.from_plant != a.hsource;
select round(sum(a.batch_wt)) into vr_stk  from dbprod.psm_data a where a.iss_date is null and a.cw_coil_no is not null and a.prod_cd = 'C9' and a.from_plant != a.hr_source;

OPEN v_hr_stk_out For 
select r_stk, vr_stk from dual

END;

Answer 2

在结束过程正文之前尝试添加此行

 Select r_stk, vr_stk from dual;

尝试调用过程并在该过程中返回值
