Help with an update with join (works in access)

Question

This is my working query in ms access...
UPDATE Caxnode AS A INNER JOIN Caxnode AS B ON A.node_alias = B.node_alias SET A.partition_Type = 'LDOM', A.node_mode = 'LOGICAL', A.host_id = b.host_id, A.num_of_proc = b.num_of_proc WHERE (((A.node_mode)='virtual' Or (A.node_mode)='regular') AND ((B.partition_Type)='LDOM'));
This doesn't work in oracle, I googled and read that update doesnt work with inner join in oracle..
can someone please help me translate this query to work on oracle?
Thanks!

Answer 1

thanks for your reply. however, im a little confused . i want to update the table caxnode for a particular node_alias if the same table has the SAME node_alias defined as partition_Type=ldom
for eg..
my table is as follows
id node_alias host_id node_mode partition_type num_procs
1 abc abc virtual null 2
2 abc xyz logical LDOM 4
3 def def virtual null 2
4 def ppp logical LDOM 8
5 abc abc regular null 3
So those that are ldoms are marked ldom in partition_type, those that are not recognised as ldoms are marked null in partition_type. LDOM's are logical in node_mode, others are either virtual or regular in node_mode.
Now since there are some old entries that are marked regular/virtual and NULL but are actually LDOMs, I need to go through the table and mark those as LDOM's which have same node_alias marked as LDOM later on.
In the table above, abc is marked as LDOM in row 2, so row 1 and 5 should reflect that. the host id should change to host_id in row 2 because the same alias is defined as ldom in row 2..
Same with def.. host_id for def should change to host_id thats in row 4 because def is also defined as ldom in row 4..
The table should look like this
id alias host_id node_type num_procs
1 abc xyz LDOM 4
2 abc xyz LDOM 4
3 def ppp LDOM 8
4 def ppp LDOM 8
5 abc xyz LDOM 4
