you need a sql book: you sumarized your question so well, you can find the
answer in any sql book in a minute, literally:
select
a.some, a.someelse, a.reference,
b.referee, b.somesome, b.somesomeelse
from tableA a, tableB b
where b.referee = a.refference
hope helps.

I now want to make a query to get all information of the first table and, if there is a reference, the corresponding information of the second table in that row. In another programming language I would just make an if-clause but how can I do this in SQL?
