创建在Oracle中具有多个外键的表

Question

我正在尝试创建一个ENCOUNTER实体表。我已经成功创建了与此表关联的所有外键表，但是当我尝试在Oracle Database Express Edition 11g上运行它时，它会不断给出以下错误消息，我找不到任何错误。 ORA-00907: missing right parenthesis以下是命令语法。

CREATE TABLE ENCOUNTER (
ENCT_ID VARCHAR2(25) PRIMARY KEY,
ENCT_DATE DATE NOT NULL,
PT_MRN NUMBER NOT NULL,
ENCT_BP VARCHAR2(10) NOT NULL,
ENCT_WT NUMBER(3,2) NOT NULL,
ENCT_TEMP NUMBER(3) NOT NULL,
ACCT_ID VARCHAR2(25) NOT NULL,
PHX_ID VARCHAR2(25) NOT NULL,
CONSTRAINT FK_PATIENT FOREIGN KEY (PT_MRN) REFERENCES PATIENT(PT_MRN)
CONSTRAINT FK_ACCOUNT FOREIGN KEY (ACCT_ID) REFERENCES ACCOUNT(ACCT_ID)
CONSTRAINT FK_PTHISTORY FOREIGN KEY (PHX_ID) REFERENCES PTHISTORY(PHX_ID));

Answer 1

我相信你在每个约束后都缺少逗号。

CREATE TABLE ENCOUNTER (
ENCT_ID VARCHAR2(25) PRIMARY KEY,
ENCT_DATE DATE NOT NULL,
PT_MRN NUMBER NOT NULL,
ENCT_BP VARCHAR2(10) NOT NULL,
ENCT_WT NUMBER(3,2) NOT NULL,
ENCT_TEMP NUMBER(3) NOT NULL,
ACCT_ID VARCHAR2(25) NOT NULL,
PHX_ID VARCHAR2(25) NOT NULL,
CONSTRAINT FK_PATIENT FOREIGN KEY (PT_MRN) REFERENCES PATIENT(PT_MRN),
CONSTRAINT FK_ACCOUNT FOREIGN KEY (ACCT_ID) REFERENCES ACCOUNT(ACCT_ID),
CONSTRAINT FK_PTHISTORY FOREIGN KEY (PHX_ID) REFERENCES PTHISTORY (PHX_ID));
