无法使用tera术语在Oracle中创建表

Question

这是我在tera术语中执行的文本文件。

DROP TABLE purchase; CREATE TABLE purchase            
( ID  NUMBER(4) NOT NULL, 
               Fname VARCHAR2(10), 
               Lname VARCHAR2(10),
               Vin NUMBER(10),
               Email VARCHAR(10), 
               unit NUMBER(10), 
               Street VARCHAR2(50), 
               Suburb VARCHAR2(50), 
               Pcode NUMBER(4),
               credit VARCHAR2(20),
               holder VARCHAR2(20),
               Expiry NUMBER(4)
               Primary key (ID) 
             );    commit;

我收到了错误

DROP TABLE purchase
           *
ERROR at line 1:
ORA-00942: table or view does not exist

       Primary key (ID)
                   *
ERROR at line 14:
ORA-00907: missing right parenthesis

使用此

DROP TABLE purchase;
CREATE TABLE purchase            
         ( ID  NUMBER(4) NOT NULL, 
           Fname VARCHAR2(10), 
           Lname VARCHAR2(10),
           Vin NUMBER(10),
           Email VARCHAR(10), 
           unit NUMBER(10), 
           Street VARCHAR2(50), 
           Suburb VARCHAR2(50), 
           Pcode NUMBER(4),
           credit VARCHAR2(20),
           holder VARCHAR2(20),
           Expiry NUMBER(4),
           CONSTRAINT purchase_pk PRIMARY KEY (ID) 
         );  

BEWARE 关于purchase不存在的第一个错误（ORA-00942）没问题......第一次运行时会发生这种情况。

或者这个：

DROP TABLE purchase;
CREATE TABLE purchase            
         ( ID  NUMBER(4) PRIMARY KEY, 
           Fname VARCHAR2(10), 
           Lname VARCHAR2(10),
           Vin NUMBER(10),
           Email VARCHAR(10), 
           unit NUMBER(10), 
           Street VARCHAR2(50), 
           Suburb VARCHAR2(50), 
           Pcode NUMBER(4),
           credit VARCHAR2(20),
           holder VARCHAR2(20),
           Expiry NUMBER(4)
         );  

将主键约束应用于列意味着“唯一”和“非空”约束。
