Sql developer database diff generating incorrect diff scripts

Question

I am wondering whether this may have to do with incorrect preference settings. Note I am NOT diffing 2 schemas that I log in as. That shouldn't matter. I log in as a DBA user.
I am getting alot of alter statements such as
alter table add constraint NOT NULL
This errors out because the table already has a NOT null constraint.
I then checked both databases to make sure I didn't run my diffs in the wrong direction. Both databases have this NOT NULL constraints.
I just checked a create table statement. The table exists in both databases. What am I missing here? Is there some setting in preferences about how database diff works?

Answer 1

Can reproduce same issue in 11gR1.. DIFF works fine in 10gR2.
I noticed that 10gR2 allows something like:
DBMS_METADATA.SET_TRANSFORM_PARAM(th,'SEGMENT_ATTRIBUTES',0);
and 11GR2 returns error similar to error SQLNAVIGATOR returns while running diff:
DBMS_METADATA.SET_TRANSFORM_PARAM(th,'SEGMENT_ATTRIBUTES',0);
end;
Error report:
ORA-31600: invalid input value 0 for parameter SEGMENT_ATTRIBUTES in function SET_TRANSFORM_PARAM
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105
ORA-06512: at "SYS.DBMS_METADATA_INT", line 8424
ORA-06512: at "SYS.DBMS_METADATA_INT", line 9484
ORA-06512: at "SYS.DBMS_METADATA", line 3950
Its safe to assume that this is SQLDEVELOPER bug. Hope it will be addressed sometime.
