Is there any way I can define an Unique constraint or unique index

Hello,
I have a problem with a Java user-defined stored procedure
and the "alter sequence" statement. I use DB2 8.1.2 and had the
same problem with 8.1.0, but not with 7.*.

ungültig.

Hello,
I have two questions about "not logged initially":

2. After using "alter table tbname activate not logged initially",
how to deactivate it?

relationship. I have a SQL statement in the "one" table which I want to
execute and insert 7 records into the "many" table, and I want them to be

Problem is, it won't let me run the SQL run as long as the one-many
relationship is established in the...

the error for all the constraints being added, but not the indexes
