ORA-02310

exceeded maximum number of allowed columns in table

Cause

The creation of an object column internally creates a number of columns, including columns for any scalar attribute at any level. The total number of columns created exceeded the maximum column limit for the table.


Action

If this object column needs to be part of the table, drop some other columns so that the limit is not exceeded.
