Question

我正在使用Oracle Apex，我在SQL查询上收到以下错误消息。

错误讯息：

无法在Builder中解析查询。如果您认为您的查询在语法上是正确的，请检查区域源下方的“通用列”复选框，以便在不进行解析的情况下继续。 ORA-00904：“LECTURE_6”。“CW_ORDER”。“B_ID”：标识符无效

我的SQL查询：

SELECT 
   "CW_ORDER"."ORD_ID" "ORDER_ID",
   "CW_ORDER"."ORD_ID" "ORD_ID", 
   "CW_ORDER"."B_ID" "B_ID",
   "CW_ORDER"."EMP_ID" "EMP_ID", 
   "CW_ORDER"."FNAME" "FNAME", 
   "CW_ORDER"."LNAME" "LNAME", 
   "CW_ORDER"."ADDRESS" "ADDRESS", 
   "CW_ORDER"."PHONE" "PHONE", 
   "CW_ORDER"."TYPE" "TYPE", 
   "CW_ORDER"."ORDERDATE" "ORDERDATE", 
   "CW_ORDER"."DELIVERYDATE" "DELIVERYDATE", 
   "CW_ORDER"."PAYMENT" "PAYMENT", 
   "CW_ORDER"."REMARKS" "REMARKS",
   "CW_ORDER"."STATUS" "STATUS",
    "CW_ORDER"."FNAME" ||' '|| "CW_ORDER"."LNAME" "CUSTOMER NAME",
    (select location from CW_BRANCH  
     where CW_BRANCH.B_ID = "#OWNER#"."CW_ORDER".B_ID) "Location"

FROM "CW_ORDER" Order by ORD_ID DESC

我只想在查询报告中显示与分支ID（B_ID）相同行对应的分支的位置。

问题出在(select location from CW_BRANCH where CW_BRANCH.B_ID = "#OWNER#"."CW_ORDER".B_ID) "Location"上。

Answer 1

使用此功能。

(select location from CW_BRANCH  
 where CW_BRANCH.B_ID = "CW_ORDER".B_ID) "Location"

此处，"CW_ORDER".B_ID在您的from子句中引用CW_ORDER，因此不需要OWNER信息。

正如您所提到的OWNER.*，它实际上是在您的OWNER子句中引用了一个名为FROM的表，因而错误。

ORA-00904：“LECTURE_6”。“CW_ORDER”。“B_ID”：标识符无效
