Need help with SQL query

I need to write a query that gets 3 codes from a table & gets the definitions of the codes from 3 other tables, with 1 select statement.

So for example, if I have "SELECT code1, code2, code3 FROM table1" and the definitions of code1 are in table2, code2 are in table3 & code3 are in table4, how can I write 1 query to get the definitions of code1, code2 & code3? Hopefully somebody understands what I mean. Thanks...

Code:

---

Select code1,code2,code3 From table1
  Inner Join table1.code1 on table2.code1
  Inner Join table1.code2 on table3.code2
  Inner Join table1.code3 on table4.code3
