PLS-00302：必须声明组件'VARIABLE_SKU_ID'

Question

我试图将我的查询结果存储到一个变量，以便我可以在另一个查询中使用它，但得到错误

create procedure store_validated_sku_id
("variable_sku_id" VARCHAR2)
as
BEGIN

SELECT vsku.SKU_ID INTO  store_validated_sku_id.variable_sku_id 
FROM vs_sku_discont_details_test discontd,vsx_dcs_sku vsku,auto_ship_view bcc 
where discontd.sku_id = vsku.JDA_SKU_ID 
  and bcc.sku_id = vsku.SKU_ID AND vsku.web_eligible = 1 
  and vsku.discontinued =0 and bcc.auto_ship_eligible is null;

END store_validated_sku_id;

/

在编译器日志中获得以下错误：

Error(5,1): PL/SQL: SQL Statement ignored
Error(5,49): PLS-00302: component 'VARIABLE_SKU_ID' must be declared
Error(5,65): PL/SQL: ORA-00904: : invalid identifier

Answer 1

• 是的，你的主要问题是用引号包装你的变量（variable_sku_id）（无论是双重还是单一，都会产生问题），你应该摆脱它们
• 但也需要将其转换为out或in out类型，因为in（默认）类型参数不能用作赋值目标。

Answer 2

将variable_sku_id放在双引号之间会使标识符名称区分大小写。

删除双引号，它应该没问题（我已将您的查询更改为使用ANSI-92语法 - 将FROM子句中的所有内容都设置为过时的旧式Oracle语法，应该避免使用）：

create procedure store_validated_sku_id
(variable_sku_id VARCHAR2)
as 
BEGIN

SELECT vsku.SKU_ID INTO  store_validated_sku_id.variable_sku_id 
FROM vs_sku_discont_details_test discontd
JOIN vsx_dcs_sku vsku 
  ON  discontd.sku_id = vsku.JDA_SKU_ID 
JOIN auto_ship_view bcc
  ON bcc.sku_id = vsku.SKU_ID 
 WHERE vsku.web_eligible = 1 
 AND vsku.discontinued = 0 
 AND bcc.auto_ship_eligible is null;

END store_validated_sku_id;

Answer 3

CREATE OR REPLACE PROCEDURE store_validated_sku_id( variable_sku_id OUT VARCHAR2 ) IS    
BEGIN    
  SELECT vsku.SKU_ID
    INTO variable_sku_id      
    FROM vs_sku_discont_details_test discontd      
    JOIN vsx_dcs_sku vsku      
      ON discontd.sku_id = vsku.JDA_SKU_ID      
    JOIN auto_ship_view bcc      
      ON bcc.sku_id = vsku.SKU_ID      
   WHERE vsku.web_eligible = 1            
     AND vsku.discontinued = 0            
     AND bcc.auto_ship_eligible is null;    
END store_validated_sku_id;
