SQL 7 - Oracle 8i - NOT NULL dropped for IDENTITY column

Question

It appears that OMWB is dropping the NOT NULL condition for columns defined as IDENTITY in SQL server 7.
SQL code to create table:
CREATE TABLE [dbo].[PCPrsnCorp] (
[PrsnCorpId] [int] IDENTITY (1, 1) NOT NULL ,
[PrsnCorpTpEnum] [tinyint] NOT NULL ,
[Name] [varchar] (128) NOT NULL ,
[NameFirstIdx] [smallint] NULL ,
[NameMidIdx] [smallint] NULL ,
[NameLastIdx] [smallint] NULL ,
[NameSuffixIdx] [smallint] NULL ,
[NameLine2Idx] [smallint] NULL ,
[CmpyId] [smallint] NULL ,
[ClsnId] [int] NOT NULL
) ON [PRIMARY]
GO
OMWB migration script:
REM
REM Message : Created Table :sa.PCPRSNCORP
REM User : system
CREATE TABLE sa.PCPRSNCORP(PRSNCORPID NUMBER (10,0) ,PRSNCORPTPENUM NUMBER
(3,0) NOT NULL,NAME VARCHAR2 (128) NOT NULL,NAMEFIRSTIDX NUMBER (5,0)
,NAMEMIDIDX NUMBER (5,0) ,NAMELASTIDX NUMBER (5,0) ,NAMESUFFIXIDX NUMBER
(5,0) ,NAMELINE2IDX NUMBER (5,0) ,CMPYID NUMBER (5,0) ,CLSNID NUMBER
(10,0) NOT NULL) TABLESPACE ORACLEFULL
NOT NULL appears to be handled correctly if colummn is not defined as IDENTITY. Is there a patch, workaround, or OMWB option to get past this?

Answer 1

Currently, the Migration Workbench converts IDENTITY columns into a BEFORE INSERT trigger and an Oracle sequence.
This trigger will fire prior to any INSERT statement executing against the table. The trigger inserts the next value of the defined sequence into the converted IDENTITY column.
The NOT NULL column attribute is therefore no longer needed.
Strictly speaking, it would do no harm to keep the NOT NULL column attribute and so I will log a bug on your behalf.
Thanks for the info.
