Syntax error in SQL statement “CREATE EXTENSION[*] IF NOT EXISTS UUID_OSSP “

I’m trying to create h2 DB schema. Here is my 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
);

JavaScript
​x
 
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);​

And I get an error

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

I resolved this by deleting create extension if not exists uuid_ossp; and adding default random_uuid() instead of default uuid_generate_v4() in tables.
