The maximum number of long columns in a table stays at 1 in version 8 although multiple BLOB and CLOB columns are allowed.
As a general aside;
I personally could never actually understand why people wanted more than
one long column in a table as the best design method for long data was
always to create a separate table containing only the long column with a
one-to-one relationship back to the real one. This method was far more
efficient as meant the long data need only be accessed when required and
not for every read of the table. As this was the accepted method for one
long column, surely another n long columns could be satisfied by another n
one-to-one tables.
I think the requirement for more than one long mainly stemmed from
ms-access ports, but I am pleased that this access oddity is not allowed in
Oracle.
