WHERE 子句中的标识符无效

Question

我正在尝试编写 SQL 以将行从一个表复制到另一个表，但在 WHERE 子句中不断收到无效标识符。我正在使用 oracle apex。

这是我的代码：

INSERT INTO CRIMECLOSED (crimeClosedID, crimeName, crimeDate, crimeNotes, 
   outsideSourceDescription, dateClosed, relatedCrimes, 
   staffID, crimeTypeID, locationID)  
SELECT CRIMEOPEN.crimeOpenID, CRIMEOPEN.crimeName, CRIMEOPEN.crimeDate, 
       CRIMEOPEN.crimeNotes,  CRIMEOPEN.outsideSourceDescription, CURDATE(), 
       CRIMEOPEN.relatedCrimes, CRIMEOPEN.staffID, CRIMEOPEN.crimeTypeID, 
       CRIMEOPEN.locationID
FROM CRIMEOPEN
WHERE CRIMEOPEN.crimeOpenID = '1';

CRIMEOPEN 表

CREATE TABLE  "CRIMEOPEN" 
(   "crimeOpenID" VARCHAR2(5), 
"crimeName" VARCHAR2(20), 
"crimeDate" DATE, 
"crimeNotes" VARCHAR2(200), 
"outsideSourceDescription" VARCHAR2(200), 
"relatedCrimes" VARCHAR2(5), 
"staffID" VARCHAR2(5), 
"crimeTypeID" VARCHAR2(5), 
"locationID" VARCHAR2(5), 
 CONSTRAINT "CRIMEOPEN_PK" PRIMARY KEY ("crimeOpenID") ENABLE
 )

我得到的错误是：

ORA-00904: "CRIMEOPEN"."CRIMEOPENID": 标识符无效

我认为错误是试图说“crimeOpenID”不是“CRIMEOPEN”中的列，但它确实是。 请问有什么帮助吗？

如果在声明表的列时使用双引号，那么在各种语句中“使用”列时也需要使用相同的格式。

因此，为了解决此问题，您应该在 select 语句中将所有列用双引号括起来（如下所示 - 仅适用于 select 语句）。

INSERT INTO CRIMECLOSED (crimeClosedID, crimeName, crimeDate, crimeNotes, 
   outsideSourceDescription, dateClosed, relatedCrimes, 
   staffID, crimeTypeID, locationID)  
SELECT "CRIMEOPEN"."crimeOpenID", "CRIMEOPEN"."crimeName", "CRIMEOPEN"."crimeDate", 
       "CRIMEOPEN"."crimeNotes",  "CRIMEOPEN"."outsideSourceDescription", CURDATE(), 
       "CRIMEOPEN"."relatedCrimes", "CRIMEOPEN"."staffID", "CRIMEOPEN"."crimeTypeID", 
       "CRIMEOPEN"."locationID"
FROM "CRIMEOPEN"
WHERE "CRIMEOPEN"."crimeOpenID" = '1';
