# 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.
