Subject Re: Problem with create table in Derby 10.2.2.0
Date Fri, 09 Feb 2007 19:01:41 GMT
Hi Leo,

Also I think following will be a better createString, I wonder why you
didn''t get any error for "generate'. Also please don't use 'Table' as table
name. I got error for that also. And KEY_ID can not have any null values,
since you are making it unique it should be declared as not null. My
suggestion for the createString is as follows

create table Table1 (SAMPLE_ID int not null generated always as identity,KEY
_ID bigint not null,KEY_INST_COUNT int, DATAOBJ blob (102400),
unique(KEY_ID));
