Question

我在Oracle中创建了以下包：

CREATE OR REPLACE PACKAGE PackageName AS 

TYPE general_item
IS
  RECORD
  (
    item_no item_t.item_no%TYPE ,
    item_type item_t.item_type%TYPE,
    item_state item_t.item_state%TYPE,
    item_name item_t.item_name%TYPE,
    prodname_no item_t.prodname_no%TYPE,
    prod_name item_t.prod_name%TYPE,
    prodname_no2 item_t.prodname_no2%TYPE,
    prod_name2 item_t.prod_name2%TYPE,
    prodtype_no item_t.prodtype_no%TYPE,
    prodtype_name item_t.prodtype_name%TYPE,
    designer_no item_t.designer_no%TYPE,
    designer_name item_t.designer_name%TYPE,
    req_assembly item_t.req_assembly%TYPE,
    unit_name item_t.unit_name%TYPE,
    valid_designer item_t.valid_designer%TYPE,
    sale_start_date item_t.sale_start_date%TYPE,
    sale_end_date item_t.sale_end_date%TYPE,
    short_material_text item_t.short_material_text%TYPE,
    imeas_ref_imp item_t.imeas_ref_imp%TYPE,
    imeas_ref_met item_t.imeas_ref_met%TYPE,
    valid_design_text item_t.valid_design_text%TYPE,
    pe_no item_t.pe_no%TYPE,
    hfb_no item_t.hfb_no%TYPE,
    hfb_name item_t.hfb_name%TYPE,
    pra_no item_t.pra_no%TYPE,
    pra_name item_t.pra_name%TYPE,
    pa_no item_t.pa_no%TYPE,
    pa_name item_t.pa_name%TYPE,
    rec_sales_price item_t.rec_sales_price%TYPE,
    currency_code item_t.currency_code%TYPE,
    base_item_no item_cty_spec_t.item_no%TYPE, --YB added 2014-05-01
    comclass_name item_comclass_t.comclass_name%TYPE); --YB added 2014-05-01


         PROCEDURE general_get_item(
        p_item_no   IN item_t.item_no%TYPE,
        p_item_type IN item_t.item_type%TYPE,
        p_item OUT general_item);


END PackageName;

这是我尝试创建的程序：

create or replace PACKAGE BODY PackageName
AS
PROCEDURE general_get_item(
    p_item_no   IN item_t.item_no%TYPE,
    p_item_type IN item_t.item_type%TYPE,
    p_item OUT general_item)
IS
BEGIN
  OPEN p_item FOR SELECT it.item_no, it.item_type, it.item_state, it.item_name, it.prodname_no , it.prod_name, it.prodname_no2, it.prod_name2, it.prodtype_no, it.prodtype_name, it.designer_no, it.designer_name, it.req_assembly, it.unit_name, it.valid_designer, it.sale_start_date, it.sale_end_date, it.short_material_text, it.imeas_ref_imp, it.imeas_ref_met, it.valid_design_text, it.pe_no, it.hfb_no, it.hfb_name, it.pra_no, it.pra_name, it.pa_no, it.pa_name, it.rec_sales_price, it.currency_code, icst.item_no as base_item_no, ict.comclass_name 
  FROM item_t it, item_cty_spec_t icst, 
  (SELECT item_no, item_type, comclass_name FROM item_comclass_t 
  WHERE valid_from < SYSDATE AND valid_to >= SYSDATE) ict
  WHERE it.item_no = icst.item_no_cty_spec (+) AND it.item_type = icst.item_type_cty_spec (+)  
  AND it.item_no = ict.item_no (+) AND it.item_type = ict.item_type (+)
  AND it.item_no = p_item_no 
  AND it.item_type = p_item_type;
END general_get_item;
END PackageName;

当我尝试创建该过程时，我收到以下消息：

错误（8,3）：PL / SQL：忽略SQL语句错误（8,8）：PLS-00456：item 'P_ITEM'不是光标

我是Oracle的新程序包和程序。

Answer 1

您无法在TYPE RECORD上打开光标。它必须是CURSOR类型。所以，只需替换整个声明 -

TYPE general_item
IS
RECORD
  (
    item_no item_t.item_no%TYPE ,
    item_type item_t.item_type%TYPE,
    item_state i
    .....


    .....
    comclass_name item_comclass_t.comclass_name%TYPE);

。通过

TYPE general_item IS REF CURSOR;

Answer 2

您无法将光标（可能是多行）提取到TYPE中。没有表结构很难想象这个字段是什么类型。无论如何更简单的方法是在游标返回一行时使用item_t％ROWTYPE。

Answer 3

如果要在Oracle中返回结果，则无需声明游标。 Oracle已经以SYS_REFCURSOR的身份代表您使用它。

所以您的代码可能看起来像-

CREATE OR REPLACE PACKAGE PackageName AS
PROCEDURE general_get_item(
        p_item_no   IN item_t.item_no%TYPE,
        p_item_type IN item_t.item_type%TYPE,
        p_item OUT SYS_REFCURSOR);
END PackageName;

然后您的包裹主体可能看起来像-

create or replace PACKAGE BODY PackageName
AS
 PROCEDURE general_get_item(
     p_item_no   IN item_t.item_no%TYPE,
     p_item_type IN item_t.item_type%TYPE,
     p_item OUT SYS_REFCURSOR)
 IS
 BEGIN
  OPEN p_item FOR
                 SELECT it.item_no
                       ,it.item_type
                       ,it.item_state
                       ,it.item_name
                       ,it.prodname_no
                       ,it.prod_name
                       ,it.prodname_no2
                       ,it.prod_name2
                       ,it.prodtype_no
                       ,it.prodtype_name
                       ,it.designer_no
                       ,it.designer_name

                       ,it.sale_end_date
                       ,it.short_material_text
                       ,it.imeas_ref_imp
                       ,it.imeas_ref_met
                       ,it.valid_design_text
                       ,it.pe_no
                       ,it.hfb_no
                       ,it.hfb_name
                       ,it.pra_no
                       ,it.pra_name
                       ,it.pa_no
                       ,it.pa_name
                       ,it.rec_sales_price
                       ,it.currency_code
                       ,icst.item_no as base_item_no
                       ,ict.comclass_name 
  FROM item_t it
  LEFT JOIN item_cty_spec_t icst ON it.item_no = icst.item_no_cty_spec
                                 AND it.item_type = icst.item_type_cty_spec
  LEFT JOIN (SELECT item_no
                   ,item_type
                   ,comclass_name
             FROM item_comclass_t 
             WHERE valid_from < SYSDATE AND valid_to >= SYSDATE) ict ON it.item_no = ict.item_no
                                                                     AND it.item_type = ict.item_type
  WHERE it.item_no = p_item_no 
  AND it.item_type = p_item_type;
 END general_get_item;
END PackageName;

还要始终使用比ANSI-92语法正确的显式联接语法。
