Joining Tables in Oracle SQL Developer -

I have four tables that I want to join and want to show output all together. I'm not sure how Syntax Oracle works for SQL developers. I know that this is a simple question for the programmer and I was hoping anyone could suggest how the code can look.

Tables are:

  JNL 1 JNL2 JNL3JNL4   
 The key is for everyone Between normal is four of these tables are  ItemID .  
 What does the query look like? Thanks   
 
 
 It really depends on how you want to connect (external or not), But you can use the default SQL Syntax For example, select  join  keyword:  
  from JNL1, JNL2, JNL3, JNL4, where JNL1, * engage to. Item id = jnl 2.itemad and jnl 2.atamid = jnl 3.imaid and jnl 3.atamid = jnl 4.itemad;   
 In addition to this you can use multiple  INNER JOINS   
  SELECT JNL1 as anything that may be INNER BiITID as JONL2 = AITAMID Inner Joint JNL 2 as CIITAMID = B.ITAMID Inner JNL 2 NDODD item ID = C. ItamID
