ORA-00922: 无法使用 ojdbc 在 oracle 中创建表

Question

I want to create the following table

CREATE TABLE EMPLOYEE (
    name_id varchar(255) PRIMARY KEY,
    modified_at TIMESTAMP,
    created_at TIMESTAMP
);

but oracle give the error

ORA-00922: missing or invalid option

I also tried the following SQL request but same issue is happening

CREATE TABLE EMPLOYEE (
    name_id varchar(255),
    modified_at TIMESTAMP,
    created_at TIMESTAMP,
    CONSTRAINT EMPLOYEE UNIQUE (name_id)
);

The request where executed using java code and the driver ojdbc6-11.2.0.4.jar

is there anything wrong in my sql?

Answer 1

CREATE TABLE EMPLOYEE ( name_id varchar(255) PRIMARY KEY, modified_at TIMESTAMP, created_at TIMESTAMP );

 CREATE TABLE EMPLOYEE ( name_id varchar(255), modified_at TIMESTAMP, created_at TIMESTAMP, CONSTRAINT EMPLOYEE UNIQUE (name_id) );

is there anything wrong in my sql?

No, it works fine db<>fiddle .

The only two things you could change are to:

• use VARCHAR2 and not VARCHAR .
• name the constraint something different to the name of the table.

CREATE TABLE EMPLOYEE (
    name_id     VARCHAR2(255),
    modified_at TIMESTAMP,
    created_at  TIMESTAMP,
    CONSTRAINT EMPLOYEE__name_id__u UNIQUE (name_id)
);

The request where executed using java code and the driver ojdbc6-11.2.0.4.jar

Remove the semi-colon at the end if you are running the statement via JDBC. A semi-colon is a statement terminator in SQL/Plus (and SQL developer) but is not necessary (and is a syntax error) when you are using JDBC and similar (when you will only ever pass a single statement and so the terminator is unnecessary).

Answer 2

Instead of the inline pk declaration you can use something like this:

CREATE TABLE EMPLOYEE (
   name_id varchar(255) PRIMARY KEY,
   modified_at TIMESTAMP,
   created_at TIMESTAMP
)
ALTER TABLE EMPLOYEE
ADD CONSTRAINT employee_pk PRIMARY KEY (name_id);
