只需在php - sql consult中从3个完全不同的表中列出搜索

I got this search tool in my News Archive page where I want the user to select a range from "A" date to "B" Date.

Example:

From: [7] [06] [2002]

To: ....[7] [07] [2015]

And 3 checkbox buttons:

[v] News Ticker

[v] Featured Article

[v] News

I need to make a consult in 3 different sql tables, and get the result of them when the checkbox is selected like if it was only one... Let me make it more clear:

If selected the news ticker, featured article and news checkboxes the sql search will get all the data from the 3 tables: z_news_ticker, z_featured_article and z_news

And I already have the html-php part ready, I just don't know how to make the sql consult to get the result of those 3 tables...

Observation: The tables are different, there's no column related to each other

Here they are:

z_news_ticker table:

z_featured_article:

z_news:
