Question

I’m working on db2. I got one table, which contains some data:

Data | Value | Lang

To Data column of this table, was added unique constraint. However, now application CAN contain many rows for the same date. So, I removed constraint, but, after reorganization of table, restart of server it still throws exceptions when I want to add more than one row with the same Data.

Unfortunately I didn’t create this table at first place, and I can’t remove data from it :/

Anyone has any idea what’s going on?

Thanks for you time!

Answer 1

Okay, it looks like there was index on this column also.

To check indexes:

select * from SYSIBM.SYSINDEXES where TBNAME= 'TABLE_NAME';

To drop index:

drop index INDEX_NAME;

Now it works! 🙂 Quite easy.
