Good Day Experts!

I have a SQL issue that I am in need of help with.  I have 3 temp tables that have the same structure.  I need to join all 3 together. However, all 3 temp tables may or may not have matching records.  Temp table 1 may be the same as Temp table 2 and 3. Temp table 1 may not have a match in 2 or 3.  It could have a match in 2 but not 3. Essentially, any combination from the 3 tables is possible.  

Thinking out loud, if I left join Temp table 2 to Temp table 1 then join Temp table 3, would I then miss out on the records that may or may not have matched between 1 and 3?

Is this possible?
