Oracle SQL Developer中的錯誤“表或視圖不存在”

Question

我正在嘗試在Oracle SQL Developer中創建表及其上的索引，但是我不斷收到錯誤消息：

錯誤報告-SQL錯誤：ORA-00942：表或視圖不存在00942。00000-“表或視圖不存在” *原因：
*行動：

我的陳述：

CREATE TABLE TAB_ATTRIBUTES_OF_RELATIONSHIP
(
REL_NAME                VARCHAR(15) not null,
ATTR_NAME             VARCHAR(15) not null, 
ATTREL_DATATYPE  VARCHAR(15) not null, 
ATTREL_DOMAIN     VARCHAR(20),

constraint PK_ATTRIBUTES_OF_RELATIONSHIP primary key (REL_Name, ATTR_NAME),
constraint FK_ATTRIBUTES_OF_RELATIONSHIP foreign key (REL_NAME)
            references RELATIONSHIPS (REL_NAME)
constraint FK_ATTRIBUTES_OF_RELATIONSHIP foreign key (ATTR_NAME)
            references ATTRIBUTES (ATTR_NAME),
);

/* Index: IDX_ATTRIBUTES_OF_RELATIONSHIP    */

Create index IDX_ATTRIBUTES_OF_RELATIONSHIP_FK on Tab_ATTRIBUTES_OF_RELATIONSHIP

(
ATTR_NAME ASC
);

Answer 1

問題似乎出在CREATE TABLE語句上。 您應注意放置逗號的位置，並可能嘗試逐步執行腳本

這是表創建語句的更正版本

CREATE TABLE TAB_ATTRIBUTES_OF_RELATIONSHIP
(
REL_NAME                VARCHAR(15) not null,
ATTR_NAME             VARCHAR(15) not null, 
ATTREL_DATATYPE  VARCHAR(15) not null, 
ATTREL_DOMAIN     VARCHAR(20),
constraint PK_ATTRIBUTES_OF_RELATIONSHIP primary key (REL_Name, ATTR_NAME),
constraint FK_ATTRIBUTES_OF_RELATIONSHIP foreign key (REL_NAME)
            references RELATIONSHIPS (REL_NAME),
constraint FK_ATTRIBUTES_OF_RELATIONSHIP foreign key (ATTR_NAME)
            references ATTRIBUTES (ATTR_NAME)
);
