MERGE bug?

[Shan R Shanmuganathan]

Try this:

create table xyz ( c1 number );

insert into xyz values ( 5 );

1 row created.

select * from xyz;
C1
----------
5

merge into xyz
using (select * from dual) A
on ( 1=1 )
when matched then
update set c1 = 10
when not matched then
insert values ( 20 );

1 row merged.

select * from xyz;

C1
----------
10

merge into xyz
using (select * from dual) A
on ( 1=2 )
when matched then
update set c1 = 10
when not matched then
insert values ( 20 );

0 row merged.

Why is it not inserting in the second merge?

9.2 SQL reference guide allows me to use any 'condition' inside the on ().

Bug??

BTW, I have 9.2.0.3.0.

Thanks,
Shan R Shanmuganathan
