That works faster in DB2 for creation of an index?

[Picaso.Leonardo]

HELLO all

That works faster in DB2 for creation of an index:
CREATE INDEX
or
Alter Table tab ADD INDEX
for Import?

Thanks.

The first one works, the second doesn't because it is already syntactically
incorrect.

You can add constraints to a table and unique constraints (primary keys are
just unique constraints) use a unique index under the covers for their
implementation. Aside from that, you have the CREATE INDEX statement to
create indexes.
