## Basic rules

- All tables must have a primary key named `id`
- Filename format: `YYYY-MM-DD-HHMM-patch-name.js`
- Avoid native SQL syntax, use knex methods, because Uptime Kuma supports SQLite and MariaDB.

## Template

```js
exports.up = function (knex) {};

exports.down = function (knex) {};

// exports.config = { transaction: false };
```

## Example

Filename: 2023-06-30-1348-create-user-and-product.js

```js
exports.up = function (knex) {
  return knex.schema
    .createTable("user", function (table) {
      table.increments("id");
      table.string("first_name", 255).notNullable();
      table.string("last_name", 255).notNullable();
    })
    .createTable("product", function (table) {
      table.increments("id");
      table.decimal("price").notNullable();
      table.string("name", 1000).notNullable();
    })
    .then(() => {
      knex("products").insert([
        { price: 10, name: "Apple" },
        { price: 20, name: "Orange" },
      ]);
    });
};

exports.down = function (knex) {
  return knex.schema.dropTable("product").dropTable("user");
};
```
