```
SELECT *
FROM sf_crime_data
LIMIT 10;
```
yyyy-mm-dd
The format of the date column is mm/dd/yyyy with times that are not correct also at the end of the date.

SELECT date orig_date, (SUBSTR(date, 7, 4) || '-' || LEFT(date, 2) || '-' || SUBSTR(date, 4, 2)) new_date
FROM sf_crime_data;

Notice, this new date can be operated on using DATE_TRUNC and DATE_PART in the same way as earlier lessons.

SELECT date orig_date, (SUBSTR(date, 7, 4) || '-' || LEFT(date, 2) || '-' || SUBSTR(date, 4, 2))::DATE new_date
FROM sf_crime_data;

Workspace

This section contains either a workspace (it can be a Jupyter Notebook workspace or an online code editor work space, etc.) and it cannot be automatically downloaded to be generated here. Please access the classroom with your account and manually download the workspace to your local machine. Note that for some courses, Udacity upload the workspace files onto https://github.com/udacity, so you may be able to download them there.
