Hi,
- is it possible to have more than one primary key in a table ?
( because if i don't know the name of the primary key, I have to use:
alter table my_table drop primary key cascade and it may be confused
....)
- how to add a primary key to an existing table ?
( alter table article modify idarticle number primary key doesn't work
)
Thanks for your answers ...
