hi

The VARCHAR datatype is currently synonymous with the VARCHAR2 datatype. Oracle recommends that you use VARCHAR2 rather than VARCHAR. In the future, VARCHAR might be defined as a separate datatype used for variable-length character strings compared with different comparison semantics

Originally there was a VARCHAR datatype.  It was improved upon and both the VARCHAR and VARCHAR2 datatypes existed simultaneously. Then at some point, VARCHAR datatype disappeared.  If you use VARCHAR instead of VARCHAR2, you will still get a VARCHAR2 datatype.

Listening...I'm interested in the answer, too, and was hoping somebody knew what that improvement over VARCHAR was.
