在Oracle中添加约束时,数据类型无效

Question

我想在Oracle中创建此表.这只是表SQL脚本.

     -- CREATE TABLES SECTION -------------------------------------------------

-- TABLE DATACENTER

CREATE TABLE DATACENTER(
  DATACENTERID INTEGER NOT NULL,
  NAME VARCHAR2(80 ) NOT NULL,
  LOCATION VARCHAR2(200 ),
  DCALLOWEDWEIGHTKG NUMBER(9,0),
  DCMAXIMUMWEIGHTKG NUMBER(9,0),
  DCALLOWEDPOWERWATT NUMBER(9,0),
  DCMAXPOWERWATT NUMBER(9,0),
  DCALLOWCOOLINGPOWERBTU NUMBER(9,0),
  DCMAXCOOLINGPOWERBTU NUMBER(9,0),
  DESCRIPTION CLOB
)
/
-- ADD KEYS FOR TABLE DATACENTER

ALTER TABLE DATACENTER ADD CONSTRAINT DATACENTERID PRIMARY KEY (DATACENTERID)
/

-- TABLE COMPONENT

CREATE TABLE COMPONENT(
  COMPONENTID INTEGER NOT NULL,
  DATACENTERID INTEGER,
  FKCOMPONENTID INTEGER,
  COMPONENTSTATSID INTEGER NOT NULL
)
/

-- ADD KEYS FOR TABLE COMPONENT

ALTER TABLE COMPONENT ADD CONSTRAINT COMPONENTID PRIMARY KEY (COMPONENTID)
/
-- CREATE RELATIONSHIPS SECTION ------------------------------------------------- 

ALTER TABLE COMPONENT ADD CONSTRAINT IS PART OF A FOREIGN KEY (DATACENTERID) REFERENCES DATACENTER (DATACENTERID)
/

ALTER TABLE COMPONENT ADD CONSTRAINT IS A SUBPART OF FOREIGN KEY (FKCOMPONENTID) REFERENCES COMPONENT (COMPONENTID)
/

错误堆栈:

table DATACENTER created.
table DATACENTER altered.
table COMPONENT created.
table COMPONENT altered.

Error starting at line 39 in command:
ALTER TABLE COMPONENT ADD CONSTRAINT IS PART OF A FOREIGN KEY (DATACENTERID) REFERENCES DATACENTER (DATACENTERID)
Error report:
SQL Error: ORA-00902: invalid datatype
00902. 00000 -  "invalid datatype"
*Cause:    
*Action:

Error starting at line 42 in command:
ALTER TABLE COMPONENT ADD CONSTRAINT IS A SUBPART OF FOREIGN KEY (FKCOMPONENTID) REFERENCES COMPONENT (COMPONENTID)
Error report:
SQL Error: ORA-00902: invalid datatype
00902. 00000 -  "invalid datatype"
*Cause:    
*Action:

编辑我编辑了代码,因为我看到一些SQL语句丢失了.如果你愿意,我可以提供架构吗？

最好的祝愿

Answer 1

您的约束名称IS PART OF A是非法标识符(因为空格).

您需要删除空格,例如IS_PART_OF_A:

ALTER TABLE COMPONENT 
   ADD CONSTRAINT IS_PART_OF_A 
   FOREIGN KEY (DATACENTERID) 
   REFERENCES DATACENTER (DATACENTERID)

编辑
我还意识到您的脚本没有正确终止单个语句.在第一个CREATE TABLE之后有一个;(或/)缺失.第一个ALTER TABLE也没有正确终止.我不知道这是否是复制和粘贴错误.

编辑2:

以下是具有正确名称,语句终止和正确顺序的完整脚本:

CREATE TABLE COMPONENT(
    COMPONENTID INTEGER NOT NULL,
    DATACENTERID INTEGER,
    FKCOMPONENTID INTEGER,
    COMPONENTSTATSID INTEGER NOT NULL
)
/

CREATE TABLE DATACENTER(
  DATACENTERID INTEGER NOT NULL,
  NAME VARCHAR2(80 ) NOT NULL,
  LOCATION VARCHAR2(200 ),
  DCALLOWEDWEIGHTKG NUMBER(9,0),
  DCMAXIMUMWEIGHTKG NUMBER(9,0),
  DCALLOWEDPOWERWATT NUMBER(9,0),
  DCMAXPOWERWATT NUMBER(9,0),
  DCALLOWCOOLINGPOWERBTU NUMBER(9,0),
  DCMAXCOOLINGPOWERBTU NUMBER(9,0),
  DESCRIPTION CLOB
)
/

ALTER TABLE DATACENTER ADD CONSTRAINT DATACENTERID PRIMARY KEY (DATACENTERID)
/

ALTER TABLE COMPONENT ADD CONSTRAINT COMPONENTID PRIMARY KEY (COMPONENTID)
/

ALTER TABLE COMPONENT ADD CONSTRAINT IS_PART_OF_A FOREIGN KEY (DATACENTERID) REFERENCES DATACENTER (DATACENTERID)
/
