錯誤本身是不言而喻的 – Abubakkar

@Abu該錯誤並不總是意味着你忘了關閉括號，所以很多時間，它不是.. – Scotch

你是否試圖在同一時間創建表？嘗試一次運行一個create table語句。 – Andrew

你想要一個獨特的密鑰，而不是替代

CREATE TABLE P_OWNER(
OWNERID    CHAR(5) NOT NULL, 
LNAME     VARCHAR2(50) NOT NULL, 
FNAME     VARCHAR2(30) NULL, 
SSN     CHAR(9) NULL, 
EMAIL     VARCHAR2(50) NULL, 
CONSTRAINT   P_OWNER_PK  PRIMARY KEY(OWNERID), 
CONSTRAINT   P_OWNER_AK1  UNIQUE(SSN), 
CONSTRAINT   P_OWNER_AK2  UNIQUE(EMAIL) 
); 


CREATE TABLE P_PROPERTY(
PROPERTYID   CHAR(5) NOT NULL, 
STREET1    VARCHAR2(50) NOT NULL, 
STREET2    VARCHAR2(50) NULL, 
CITY     VARCHAR2(50) DEFAULT 'FITCHBURG', 
STATE     CHAR(2) DEFAULT 'MA', 
ZIP     CHAR(10) NULL, 
SQFOOTAGE    NUMBER(5,0) NULL, 
HAS_AC    CHAR(1) NULL, 
ISHOUSE    CHAR(1) NOT NULL, 
CONSTRAINT   P_PROPERTY_PK    PRIMARY KEY(PROPERTYID), 
CONSTRAINT   P_PROPERTY_ADDRESS_AK1  UNIQUE(CITY, STATE, STREET1, STREET2, ZIP) 
);

問題是ALTERNATE KEY嘗試UNIQUE

CREATE TABLE P_OWNER(
    OWNERID    CHAR(5) NOT NULL, 
    LNAME     VARCHAR2(50) NOT NULL, 
    FNAME     VARCHAR2(30) NULL, 
    SSN     CHAR(9) NULL, 
    EMAIL     VARCHAR2(50) NULL, 
    CONSTRAINT   P_OWNER_PK  PRIMARY KEY(OWNERID), 
    CONSTRAINT   P_OWNER_AK1  UNIQUE (SSN), 
    CONSTRAINT   P_OWNER_AK2  UNIQUE (EMAIL) 
    ); 

CREATE TABLE P_PROPERTY(
    PROPERTYID   CHAR(5) NOT NULL, 
    STREET1    VARCHAR2(50) NOT NULL, 
    STREET2    VARCHAR2(50) NULL, 
    CITY     VARCHAR2(50) DEFAULT 'FITCHBURG', 
    STATE     CHAR(2) DEFAULT 'MA', 
    ZIP     CHAR(10) NULL, 
    SQFOOTAGE    NUMBER(5,0) NULL, 
    HAS_AC    CHAR(1) NULL, 
    ISHOUSE    CHAR(1) NOT NULL, 
    CONSTRAINT   P_PROPERTY_PK    PRIMARY KEY(PROPERTYID), 
    CONSTRAINT   P_PROPERTY_ADDRESS_AK1  UNIQUE(CITY, STATE, STREET1, STREET2, ZIP) 
    );

的alternate key (or secondary key)是一個不選擇任何候選人鍵是主鍵（ PK）。你不能在Oracle中創建一個備用密鑰，它只是概念。

你可以將它們創建爲唯一密鑰。 –
