### `generate_col()`

Returns a Generator that will produce an array of values for the column for the given query.
Differrently from the `get_col()` method, this method will run unbounded queries (queries without a `LIMIT` set) in batches, ensuring as-efficient-as-possible use of the database and memory.

```php
$meta_values = DB::generate_col(
DB::table( 'postmeta' )
->select( 'meta_value' )
->where( 'meta_key', 'some_key' )
->getSQL()
);

foreach( $meta_values as $meta_value ) {
// Do something with the meta value.
}
```

### `get_results()`

Returns an array of rows for for the given query.

```php
$private_posts = DB::get_results(
DB::table( 'posts' )
->select( '*' )
->where( 'post_status', 'private' )
->getSQL()
);
```

);

foreach( $private_posts as $private_post ) {
// Do something with the post.
}
```

### `esc_like()`

Escapes a string with a percent sign in it so it can be safely used with [Where LIKE](#where-like-clauses) without the percent sign being interpreted as a wildcard character.
