adding a column with a default value

quinnd6 · 2007-07-11 14:22:30

I need to add a column with a default value in sql plus so that when a row is added to the table this column will have this particular value. would it be something like this? alter table thetable add (new_column_name varchar2(100) default 'defaultvalue');

Indeed. Google says:

ALTER TABLE table_name
ADD(fieldname data_declaration constraint_definitions);

If it operates like most other SQL implementations, the inclusion of a default value means that all historical data will also contain the default value for that column.

Alternately, add the column, run an update, commit the change.
