Online Editor

You can try RayQL using the Online RayQL editor.

Installation

You can install RayQL by running the following command in your terminal:

curl -s https://raw.githubusercontent.com/harshdoesdev/rayql/main/install.sh | sh

Schema Definition

You can define your database schema by creating a RayQL file called schema.rayql.

For example, it might look something like this:

# Enum for user types

enum user_type {
    admin
    developer
    normal
}

# Model declaration for 'user'

model user {
    id: int primary_key auto_increment,
    username: str unique,
    email: str unique, # this is an inline comment
    phone_number: str?,
    user_type: user_type default(user_type.normal)
}

# Model declaration for 'post'

model post {
    id: int primary_key auto_increment,
    title: str default('New Post'),
    content: str,
    author_id: int foreign_key(user.id),
    created_at: timestamp default(now()),
}

Then, when you run the rayql print command, it will generate and output the SQL equivalent of that model, which for the above example should look something like this:

CREATE TABLE IF NOT EXISTS user (
    id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
    username TEXT NOT NULL UNIQUE,
    email TEXT NOT NULL UNIQUE,
    phone_number TEXT NULL,
    user_type TEXT NOT NULL CHECK(user_type IN ('admin', 'developer', 'normal')) DEFAULT 'normal'
);

CREATE TABLE IF NOT EXISTS post (
    id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
    title TEXT NOT NULL DEFAULT 'New Post',
    content TEXT NOT NULL,
    author_id INTEGER NOT NULL,
    created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (author_id) REFERENCES user(id)
);
