(Doc ID 1529239.1)

Last updated on MAY 15, 2017

Applies to:

Oracle Database - Enterprise Edition - Version to [Release 11.2]
Information in this document applies to any platform.


The Apply process generates errors : ORA-26786 and ORA-01403 on a table which has recently had a
column added with non null default value specified.

Starting with release 11.1, if a new column is added , the existing rows in the table are not immediately updated . This
allows the addition of the column to complete quickly. In view of this a record must be kept of the fact that when Oracle
subsequently access a row it needs to take account of the new default column value.

To achieve this sys.col$.property , bitmask 0x40000000 will be set (1073741824) for the table /object concerned to indicate
that the table has had a new column added with non null default setting.
