varchar with variable length
Hi
I would store strings with variable length on a table of a database - using Apache Derby.
After that I looked on Internet, I suppose to know that the _(new)_ SQL type "VARCHAR2", allows to do that (to store strings with with not fix size).
In my search anywhere I was not able to know if VARCHAR2 can be used with derby.
My ask is: derby implements the use of VARCHAR2 and, if not, I would like have some advice about another way to solve my problem.
Regards
Angelo
