怎么调用存储过程和函数？

1.增加操作： 
       public static void StockIns(string ps_SupplierName, int pn_ItemQty, string ps_ItemDesc, string ps_ComeDate,
            string ps_AttachedFile, string ps_SupAddress, string ps_SupPhone, string ps_SupFax,
            string ps_SupEmail, string ps_UserNo, ref string ps_HKStockItemNo)
        {
            // 创建参数
            OracleParameter[] parms = new OracleParameter[]
            {
                new OracleParameter("ps_SupplierName", OracleType.VarChar, 200),
                new OracleParameter("pn_ItemQty", OracleType.Int32, 10),
                new OracleParameter("ps_ItemDesc", OracleType.VarChar, 400),
                new OracleParameter("ps_ComeDate", OracleType.VarChar, 20),
                new OracleParameter("ps_AttachedFile", OracleType.VarChar, 100),
                new OracleParameter("ps_SupAddress", OracleType.VarChar, 200),
                new OracleParameter("ps_SupPhone", OracleType.VarChar, 60),
                new OracleParameter("ps_SupFax", OracleType.VarChar, 60),
                new OracleParameter("ps_SupEmail", OracleType.VarChar, 100),
                new OracleParameter("ps_UserNo", OracleType.VarChar, 20),
                new OracleParameter("ps_HKStockItemNo", OracleType.VarChar, 20,ParameterDirection.Output, true, 0, 0, "", DataRowVersion.Default, null)
            };

            // 给参数赋值
            parms[0].Value = ps_SupplierName;
            parms[1].Value = pn_ItemQty;
            parms[2].Value = ps_ItemDesc;
            parms[3].Value = ps_ComeDate;
            parms[4].Value = ps_AttachedFile;
            parms[5].Value = ps_SupAddress;
            parms[6].Value = ps_SupPhone;
            parms[7].Value = ps_SupFax;
            parms[8].Value = ps_SupEmail;
            parms[9].Value = ps_UserNo;
           
            OraHelper.ExecuteNonQuery(OraHelper.connstr, CommandType.StoredProcedure, "KXSCMIII.PKG_PU_HKSTOCK.Pro_StockIns", parms);
            ps_HKStockItemNo = parms[10].Value.ToString(); // 返回存货单号

       }
在前台*.aspx.cs文件里面调用：
                string strBill = "";
                HKStockDataAccess.StockIns(txtSupplierName.Text.Trim(), Int32.Parse(txtItemQty.Text.Trim()), txtItemDesc.Text.Trim(),
                                           txtComeDate.Text.Trim(), strServerFullPath, txtSupAddress.Text.Trim(), txtSupPhone.Text.Trim(),
                                           txtSupFax.Text.Trim(), txtSupEmail.Text.Trim(), Session["userno"].ToString(),ref strBill);

2.修改操作：
     public static void ClaimStock(string ps_HKStockItemNo, string ps_Buyer,
                                      string ps_DeliNo, string ps_UserNo)
        {
            // 创建参数
            OracleParameter[] parms = new OracleParameter[]
            {
                new OracleParameter("ps_HKStockItemNo",OracleType.VarChar,20),
                new OracleParameter("ps_Buyer",OracleType.VarChar,20),
                new OracleParameter("ps_DeliNo",OracleType.VarChar,20),
                new OracleParameter("ps_UserNo",OracleType.VarChar,20)
            };

            // 给参数赋值
            parms[0].Value = ps_HKStockItemNo;
            parms[1].Value = ps_Buyer;
            parms[2].Value = ps_DeliNo;
            parms[3].Value = ps_UserNo;

            OraHelper.ExecuteNonQuery(OraHelper.connstr, CommandType.StoredProcedure, "KXSCMIII.PKG_PU_HKSTOCK.Pro_ClaimStock", parms);
        }

3.查询操作：
    public static DataTable StockDetailGet(string ps_HKStockItemNo)
        {
            // 创建参数
            OracleParameter[] parms = new OracleParameter[]
            {
                new OracleParameter("ps_HKStockItemNo",OracleType.VarChar,20),
                new OracleParameter("returncur", OracleType.Cursor, 2000, ParameterDirection.Output, true,
                0, 0, "", DataRowVersion.Default, null)
            };

            // 给参数赋值
            parms[0].Value = ps_HKStockItemNo;

            // 取记录集
            DataSet ds = OraHelper.ExecuteDataset(OraHelper.connstr, CommandType.StoredProcedure,
                "KXSCMIII.PKG_PU_HKSTOCK.Pro_StockDetailGet", parms);

            return ds.Tables[0];
        }

4.调用函数：
     public static string BuyerNameGet(string ps_CardNo)
        {
            // 创建参数
            OracleParameter[] parms = new OracleParameter[]
            {
                new OracleParameter("ps_CardNo", OracleType.VarChar, 20),
                new OracleParameter("ps_FullName", OracleType.VarChar, 80, ParameterDirection.ReturnValue, true, 0, 0, "", DataRowVersion.Default, null)
            };

            // 给参数赋值
            parms[0].Value = ps_CardNo;
           
            OraHelper.ExecuteNonQuery(OraHelper.connstr, CommandType.StoredProcedure, "KXSCMIII.PKG_PU_HKSTOCK.Fun_BuyerNameGet", parms);
            return parms[1].Value.ToString(); // 返回业务员的中文名
        }
