The events table tracks every time a user performs a certain action (like, post_enter, etc.) on a platform. An example of this table would look like this:
| user_id | created_at | action | platform |
|---|---|---|---|
| 1 | 2021-01-01 12:00:00 | email_opened | Android |
| 2 | 2021-01-01 12:05:00 | like | Outlook |
| 3 | 2021-01-01 12:10:00 | post_enter | Gmail |
| 4 | 2021-01-01 12:15:00 | post_cancel | Outlook |
| 5 | 2021-01-01 12:20:00 | like | Gmail |
What query would you write to determine how many different users gave a like on June 6, 2020?
Example:
Input:
events table
| Column | Type |
|---|---|
| user_id | INTEGER |
| created_at | DATETIME |
| action | VARCHAR |
| platform | VARCHAR |
Output
| Column | Type |
|---|---|
| num_users_gave_like | INTEGER |
