oracle用以下sql语句新建表时,出现“标识符无效”错误:
create table users(
user_id integer not null,
user_name varchar2(10),
login_name varchar2(10) not null,
password VARCHAR2(32) not null,
USER_TYPE CHAR(1) default 'N' not null constraint CKC_USER_TYPE_USERS check(USER_TYPE in ('N','A')),
STS CHAR(1) default 'A' not null constraint CKC_STS_USERS check(STS in ('A','D')),
constraint PK_USER primary key(USER_ID),
)
发现把最后一个,去掉就可以了
