OCI-30729

maximum number of columns exceeded

Cause

The Oracle maximum column limit was exceeded. Adding scope or a referential constraint on a REF column requires the creation of additional columns internally if the object identifier of the target table is primary key based. The result is that the Oracle maximum column limit is exceeded.


Action

Drop some columns and retry the operation.
