I want to know reason behind the below code

```
 $this->db->select("DATE_FORMAT(`current_date`, '%M-%d-%Y' ) as date_human",  FALSE);

```

When i'm using the above code, it is returning a result `July-09-2015`, Now i want to know what is the use of `FALSE` here.Because I'm getting the same result when not adding FALSE.

I have referred the [LINK]([Date format with codeigniter](https://stackoverflow.com/questions/11074547/date-format-with-code) igniter). In this, the expert says that **it will stop CI from trying to auto-protect these names.**

**Edit:**
When I use `$this->db->last_query`, the query i'm getting is: 

```
 SELECT *, DATE_FORMAT(current_date, '%M-%d-%Y' ) as date_human FROM `user_data` WHERE id = '57'

```

when using both FALSE and without FALSE.

I want to know the difference and also the use of FALSE.
Guide me to proceed.
