# Info
https://knexjs.org/guide/migrations.html#knexfile-in-other-languages
## 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");
};
```
