# NEW MODULE - SQL BEST PRACTICES

## Create a new table

**Example:**
```
CREATE TABLE IF NOT EXISTS `table`(
  `id` int(11) unsigned NOT NULL,
  `column` smallint(6) unsigned,
  `active` BOOLEAN DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
```

**Boolean datatype in mysql:**
Use `TinyInt(1)` or `Boolean` (this is the same thing)

`bit(1)` can also work, but it may require a syntax like `b'(0)` and `b'(1)` when inserting (not sure).

If there are multiple booleans in the same table, bit(1) is better, otherwise it's the same result.


## Rules

- Use `InnoDB` as engine for dynamic tables (most likely in the `auth` and `characters` databases).
- Use `MyISAM` for **read-only** tables (in `world` database), but if you're not sure, just use innoDB.
- Use `utf8` as charset.
