Migration System
----------------

[](#migration-system)

### Important Notes

[](#important-notes)

ClickHouse migrations use Laravel's default `migrations` table to track migration status, rather than creating additional tables in ClickHouse. This ensures migration records are consistent with other Laravel migrations.

### Creating Migration Files

[](#creating-migration-files)

Use the `make:clickhouse-migration` command to quickly create migration files:

```
# Basic usage
php artisan make:clickhouse-migration create_users_table

# Specify table name
php artisan make:clickhouse-migration create_orders_table --table=orders

# Create table (explicitly specified)
php artisan make:clickhouse-migration create_products_table --create

# Custom fields
php artisan make:clickhouse-migration create_analytics_table --columns="user_id:int,name:string,score:float,is_active:bool,tags:array"

# Specify path
php artisan make:clickhouse-migration create_test_table --path=database/migrations/custom
```

### Supported Field Types

[](#supported-field-types)

The command supports the following field type mappings:

- `string` → `String`
- `int` / `integer` → `Int32`
- `bigint` → `Int64`
- `float` → `Float32`
- `double` → `Float64`
- `decimal` → `Decimal(10,2)`
- `bool` / `boolean` → `UInt8`
- `date` → `Date`
- `datetime` / `timestamp` → `DateTime`
- `array` → `Array(String)`
- `json` → `String`
