Actually, Forms does not use LONG fields in the database. I just re-checked
my listings of the FORM_ tables and found nary a long. Another obvious
place for LONGS, in the HELP table, is also just a series of CHAR columns.
Perhaps of Oracle corp used LONGs in its applications, it would better
appreciate what a pain they are to use. To calc the length, use the PL/SQL
script I posted earlier. Forget about being able to do "create table x
as select * from y;". And get used to chaining, which I have found to
lead to greatly increased change of database block corruption problems.
Something constructive should come here.
