Question

我创建了一个存储过程 - 它在服务器上成功创建但是当我执行它时，我收到Procedure Completed消息，但它没有返回任何输出。

程序如下

CREATE OR REPLACE PROCEDURE DFADMIN.USP_GETPICKLIST_DF
(
 P_ORD_TYPE IN varchar2,
 P_PICKLIST_OUT OUT SYS_REFCURSOR,
 P_PICKLIST_ORD OUT SYS_REFCURSOR
)
AS
 v_TotalOpenOrder integer;
 v_AstockQty integer;
 v_BstockQty integer;
 v_loopCounter integer;
 v_Astock integer;
 v_Bstock integer;
 v_TotalBStockQty integer;

 BEGIN
    SELECT COUNT(DISTINCT ORD_NBR) INTO v_TotalOpenOrder  FROM DFADMIN.DF_ORDERS WHERE ORD_STATUS='OPEN' AND ORD_TYPE='DF';
 begin
        if v_TotalOpenOrder>0 then
            v_BstockQty:=round(((v_TotalOpenOrder*60)/100),0);
            v_AstockQty:=v_TotalOpenOrder-v_BstockQty;
             select count(1) into v_Astock  from DFADMIN.Ro_HIST where Process='ASTOCK' AND ORDER_TYPE='DF';
            select count(1) into v_Bstock  from DFADMIN.Ro_HIST where Process='BSTOCK' AND ORDER_TYPE='DF';

            if (v_Bstock < v_BstockQty) then
                open P_PICKLIST_OUT for
                    select T.QTY,T.PUTAWAY_BIN BIN,T.BOXID BOX_ID ,T.PICKQTY PICK_QTY from

                    ELSE 
                    begin
                              open P_PICKLIST_OUT for
                    select T.QTY,T.PUTAWAY_BIN BIN,T.BOXID BOX_ID ,T.PICKQTY PICK_QTY from

                        group by I.PUTAWAY_BIN,I.BOXID,I.QTY, I.PROCESS,'1'
                    ) t  order by  T.QTY asc;
                    open P_PICKLIST_ORD for
                    select distinct ORD_NBR,'' QTY,''  BIN,'' BOX_ID ,'' PICK_QTY from  DFADMIN.DF_ORDERS where ORD_STATUS='OPEN' AND ORD_TYPE='DF';
                    end ;

            end if;

        end if;

   end;

 END USP_GETPICKLIST_DF;

在此过程中，有一个输入参数和2个输出参数。

在您的程序中，没有dbms_output或类似的东西，这会导致输出/显示任何数据。

有两个输出参数是sys_refcursor类型，所以我想在执行过程后，您正在考虑将这些参数作为所需的输出内容。在调用该过程之后，您可以将这些游标提取到变量中，然后例如显示这样的数据。

declare
vpicklist_out sys_refcursor;
vpicklist_ord sys_refcursor;
myRecord mytable%ROWTYPE;
begin
USP_GETPICKLIST_DF('somestring', vpicklist_out ,vpicklist_ord );
 LOOP
      FETCH vpicklist_out INTO myRecord1;
        EXIT WHEN vpicklist_out%NOTFOUND;
       dbms_output.put_line(to_char(myRecord1.col1));
  END LOOP;
end;

请注意，我不知道您数据的确切结构，因此myRecord在我的示例中声明为某个名为mytable的表的ROWTYPE。

已创建存储过程但未返回输出
