To unite data from two different tables. Say you had a table of your customers and a table of your staff and you wanted to list the names of all people from both tables in a single list, you would use a union query. Your SQL command would be something like this:
Select Firstname, Surname from Customers
Union Select Firstname, Surname from Employees
You would then get a list of two fields, taking data from the two tables. The field names don't have to be the same in both tables, as they are in the example, but the order in which you list them should be corresponding.

How do you combine two tables data without using joins?
One way to combine data from two tables without using joins is to use a UNION clause. This allows you to stack the results of two queries on top of each other, combining the data from both tables.

This way, you can indirectly combine data from both tables without using explicit joins.
