Question

我试图编写SQL来将一行从一个表复制到另一个表但我在WHERE子句中一直得到一个无效的标识符。我使用的是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：＆＃34; CRIMEOPEN＆＃34;。＆＃34; CRIMEOPENID＆＃34;：无效标识符

我认为错误在于试图说出“犯罪贿赂”。不是“CRIMEOPEN＆＃39;”中的专栏。但它是。有什么帮助吗？

如果在声明表格的列时使用双引号，那么当＆＃34;使用＆＃34;时，也需要使用相同的格式。各种陈述中的列。

因此，为了解决这个问题，你应该在select语句中用双引号括起所有列（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';
