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)); On 2/9/07, Mamta Satoor <[EMAIL PROTECTED]> wrote:
Leo, You need to use BIGINT rather than long for KEY_ID column.
