ORA-01792: maximum number of columns in a table or view is 1000..

Answer / guest

Cause: An attempt was made to create a table or view with
more than 1000 columns, or to add more columns to a table or
view which pushes it over the maximum allowable limit of
1000. Note that unused columns in the table are counted
toward the 1000 column limit.

Action: If the error is a result of a CREATE command, then
reduce the number of columns in the command and resubmit. If
the error is a result of an ALTER TABLE command, then there
are two options: 1) If the table contained unused columns,
remove them by executing ALTER TABLE DROP UNUSED COLUMNS
before adding new columns; 2) Reduce the number of columns
in the command and resubmit.
