java - SQL语句语法错误 "CREATE EXTENSION[*] IF NOT EXISTS UUID_OSSP "

Question

我正在尝试创建 h2 DB 架构。这是我的sql

create extension if not exists uuid_ossp;

create table users
(
    user_id     uuid default uuid_generate_v4() not null,
    name        varchar(255),
    created_on  timestamp,
    modified_on timestamp
);

create table product
(
    product_id  uuid default uuid_generate_v4() not null,
    name        varchar(25),
    created_on  timestamp,
    modified_on timestamp
);

create table products_users
(
    user_id    uuid,
    product_id uuid
);

我收到一个错误

Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Syntax error in SQL statement "CREATE EXTENSION[*] IF NOT EXISTS UUID_OSSP "; expected "OR, FORCE, VIEW, ALIAS, SEQUENCE, USER, TRIGGER, ROLE, SCHEMA, CONSTANT, DOMAIN, TYPE, DATATYPE, AGGREGATE, LINKED, MEMORY, CACHED, LOCAL, GLOBAL, TEMP, TEMPORARY, TABLE, SYNONYM, PRIMARY, UNIQUE, HASH, SPATIAL, INDEX"; SQL statement: create extension if not exists uuid_ossp [42001-199]

Answer 1

我通过删除create extension if notists uuid_ossp;并在表中添加default random_uuid()而不是default uuid_generate_v4()解决了这个问题.
