如何解决 Missing Paranthesis 错误
How do I solve the Missing Paranthesis error
我正在尝试创建 table 命令来创建关系;
create table Driver(
Driver_Licence char(15) primary key,
SSN int unique,
First_Name varchar(50) not null,
Last_Name varchar(50),
Birth_Date date DEFAULT '1900-01-01',
Hire_Date date COMMENT 'Hire_Date is the date that employee was first Hired',
State char(2),
INDEX (State),
CONSTRAINT CHK_Driver_HireDate CHECK(Hire_Date > Birth_Date)
);
但是我一直收到这个错误:
Error report -
ORA-00907: missing right parenthesis
00907. 00000 - "missing right parenthesis"
*Cause:
*Action:
我一直在想办法解决这个问题,但我一直无法弄清楚如何解决它。如果你们中的一位能帮助我,那将是一个很大的帮助!
我认为 Oracle 既不支持表中的内联注释也不支持索引的创建。这些需要是单独的语句。
Oracle 建议使用 varchar2()
而不是 varchar()
。日期字面量应以 date
:
开头
create table Driver(
Driver_Licence char(15) primary key,
SSN int unique,
First_Name varchar2(50) not null,
Last_Name varchar2(50),
Birth_Date date DEFAULT date '1900-01-01',
Hire_Date date,
State char(2),
CONSTRAINT CHK_Driver_HireDate CHECK(Hire_Date > Birth_Date)
);
comment on column driver.hire_date is 'Hire_Date is the date that employee was first Hired';
create index idx_driver_state on driver(state);
Here 是一个 db<>fiddle.
