Question

Joins are usually used to fetch data from 2 tables using a common factor from either tables

Is it possible to use a join statement using a table and results of another SQL statement and if it is what is the syntax

Answer 1

Sure, this is called a derived table

such as:

select a.column, b.column
from
    table1 a
join (select statement) b 
    on b.column = a.column

keep in mind that it will run the select for the derived table in entirety, so it can be helpful if you only select things you need.

EDIT: I’ve found that I rarely need to use this technique unless I am joining on some aggregated queries…. so I would carefully consider your design here.
For example, thus far most demonstrations in this thread have not required the use of a derived table.
