ORA-00906：缺少左括號

Question

create table widep(
cac NUMBER, 
ddate DATE, 
dtime TIMESTAMP, 
type VARCHAR2, 
amount NUMBER(10,2), 
constraint qwe foreign key(cac) references cust(cac) 
) 

Answer 1

的完整錯誤消息指出Error at CommandLine:5 Column:15這是這個位置：

type VARCHAR2, 
      ^^^ 

VARCHAR2所需的尺寸參數來定義字符的最大數目。使用類似

create table widep(
cac NUMBER, 
ddate DATE, 
dtime TIMESTAMP, 
type VARCHAR2(100), 
amount NUMBER(10,2), 
constraint qwe foreign key(cac) references cust(cac) 
); 

Answer 2

 
CREATE TABLE widep(
cac NUMBER(10,2) not null, 
date DATE, 
dtime TIMESTAMP, 
type VARCHAR2(50), 
amount NUMBER(10,2), 
CONSTRAINT cac_fk FOREIGN KEY key(cac) REFERENCES cust(cac) 
);
