執行多個oracle函數返回錯誤

Question

正如你可以看到我試圖執行兩個oracle函數使用c＃ 第一個函數F_INS_ORDER_DATA返回值將被用作參數與第二個但當第二個函數執行F_INS_ORDER_DATA_DETAILS我越來越以下錯誤

我測試蟾蜍兩個功能，他們精做

1. 工作我錯過了什麼？
2. 請，如果有任何改善我的代碼或更好的方法來做到這一點，我會爲任何建議

ORA-06550真的很感謝：第1行，第7列：

PLS- 00221： 'F_INS_ORDER_DATA_DETAILS' 不是過程或是 未定義

Answer 1

Oracle過程和功能之間進行區分。

過程存儲的代碼不返回值。函數是存儲返回一個值的代碼。你使用它們的方式（在Oracle中）有些不同。

由於數據庫抱怨F_INS_ORDER_DATA_DETAILS不是一個程序，它可能是一個函數（返回值），但你不抓住它就像你在第一次調用做：

cmd.Parameters.Add(":vORDER_ID", OracleDbType.Int32, ParameterDirection.ReturnValue); 

因此，請確定您使用的是存儲過程：

create or replace procedure F_INS_ORDER_DATA_DETAILS ... 

或從函數捕獲返回值。

Answer 2

using (OracleConnection conn = new OracleConnection(connstr)) 
using (OracleCommand cmd = new OracleCommand(cmdtxt01, conn)) 
{ 
    try 
    { 
     conn.Open(); 

     cmd.CommandText = cmdtxt01; 
     cmd.CommandType = CommandType.StoredProcedure; 

     cmd.Parameters.Add(":vORDER_ID", OracleDbType.Int32, ParameterDirection.ReturnValue); 

     cmd.Parameters.Add(new OracleParameter(":P_CUSTOMER_ID", OracleDbType.Int32)).Value = TB_CUSTOMER_ID.Text; 
     cmd.Parameters.Add(new OracleParameter(":P_ORDER_NOTE", OracleDbType.Varchar2)).Value = TB_ORDER_NOTE.Text; 
     cmd.Parameters.Add(new OracleParameter(":P_CREATED_BY", OracleDbType.Varchar2)).Value = "SYSTEM"; 
     //excute first SP 
     cmd.ExecuteNonQuery(); 
     //get the value 
     TB_INVOICE_ID.Text = cmd.Parameters[":vORDER_ID"].Value.ToString(); 
     int INVOICE_ID; 
     // parse return value 
     int.TryParse(TB_INVOICE_ID.Text, out INVOICE_ID); 

     // now set 2nd SP 
     cmd.CommandText = cmdtxt02; 
     cmd.CommandType = CommandType.StoredProcedure; 

     foreach (DataGridViewRow Row in DGV_INVOICE.Rows) 
     { 
      cmd.Parameters.Clear(); 
      cmd.Parameters.Add(new OracleParameter(":P_ORDER_ID", OracleDbType.Int32)).Value = INVOICE_ID; 
      cmd.Parameters.Add(new OracleParameter(":P_PRODUCT_ID", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_PRODUCT_ID"].Index].Value; 
      cmd.Parameters.Add(new OracleParameter(":P_UNIT_PRICE", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_UNIT_PRICE"].Index].Value; 
      cmd.Parameters.Add(new OracleParameter(":P_QUANTITY", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_QUANTITY"].Index].Value; 
      cmd.Parameters.Add(new OracleParameter(":P_DISCOUNT", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_DISCOUNT"].Index].Value; 
      cmd.Parameters.Add(new OracleParameter(":P_ORDER_STATUS", OracleDbType.Varchar2)).Value = '1'; 
      cmd.Parameters.Add(new OracleParameter(":P_ITEM_NOTE", OracleDbType.Varchar2)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_ITEM_NOTE"].Index].Value; 
      cmd.Parameters.Add(new OracleParameter(":P_CREATED_BY", OracleDbType.Varchar2)).Value = "SYSTEM"; 

      cmd.ExecuteNonQuery(); 
     } 


    } 
    catch (Exception EX) 
    { 
     MessageBox.Show(EX.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); 
     return; 
    }
