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