ANY ideas why is this happening?

Re: DBVisualizer 6.0.1 : ALTER TABLE for Oracle returned error
Hi Zaimi, Which version of Oracle are you using? Thanks, Hans

Re: DBVisualizer 6.0.1 : ALTER TABLE for Oracle returned error
Hans,

Your question triggered me to test both of our Oracle 10G db instance .

Additional clarification --  ALTER TABLE 'GUI navigator' popped up with 10G but not with 8i.

Thanks.

Re: DBVisualizer 6.0.1 : ALTER TABLE for Oracle returned error
Thanks Zaimi, There seems to be a problem with Alter Table (and most likely the DDL tab) specifically for Oracle 8 (for Oracle 9 and 10 it works fine). We're looking into it. Regards, Hans Message was edited by: Hans Bergsten

Re: DBVisualizer 6.0.1 : ALTER TABLE for Oracle returned error
Hi Zaimi, This should be fixed in the next version. I found a difference in the Oracle system tables used for Alter Table and the DDL tab that explains this problem and changed the code accordingly. I can not, however, test it to be 100% sure because we do not have an Oracle 8i installation available and Oracle no longer have 8i available for download. Please test it with the new release when it becomes available. Thanks, Hans
