I've looked through the documentation, but I can't find the size of the
limit of varchar...?

All I found was in the User's Guide:

Character Type        Storage        Description
---------------------------------------------------
varchar(n)        (4+n) bytes    variable length with limit
---------------------------------------------------

What does 4+n bytes mean?  And what is the limit?

 Anyone? And is there support for varchar2?

Thanx.
