Help with a Merge statement in oracle


Hi,
 Below is the merge statement I was using to Update and insert  data into a table. But the problem is  the conditions  in the Update statement are not working. I mean rows are not being updated, but when I remove one of the condition then it works.

MERGE INTO table  a
     USING table b
        ON (b.id = a.id)
WHEN MATCHED
THEN
   UPDATE SET
      a.col1 = b.col1,
      a.col2 = b.col2,
      a.col3 = 13
           WHERE  a.col3 = 6  and
                      b.col4 ='N'
WHEN NOT MATCHED
THEN
   INSERT     (a.col1, a.col2, a.col3)
       VALUES (b.col1, b.col3, 1)
       where b.col4 = 'N'

Use both conditions separately. You should get the same result!

how can we use them separately, I mean using a seperate update statement. If so then it won't work for me because it has to update only when both conditions are met.
Try this please and let me know the result:
MERGE INTO table  a
     USING table b
        ON (b.id = a.id)
WHEN MATCHED
THEN
   UPDATE SET
      a.col1 = b.col1,
      a.col2 = b.col2,
      a.col3 = 13
           WHERE  a.col3 = 6  and
                      b.col4 ='N'
WHEN NOT MATCHED
THEN
   update set     
   a.col1 = b.col1, 
   a.col2 = b.col3,
   a.col3 = 1
   where b.col4 = 'N'

i believe i might of rushed abit into answering that one!

MERGE INTO table  a
     USING table b
        ON (b.id = a.id)
WHEN MATCHED
THEN
   UPDATE SET
      a.col1 = b.col1,
      a.col2 = b.col2,
      a.col3 = 13
           WHERE  a.col3 = 6  and
                      b.col4 ='N'
WHEN NOT MATCHED
THEN
   INSERT  into a   (a.col1, a.col2, a.col3)
       VALUES (b.col1, b.col3, 1)
       where b.col4 = 'N'
Hi,
 It is saying oracle error ORA-))90% missing keyword near the second update statement.

But when not matched  it should insert because it is a new record.
sorry ORA -00905
MERGE INTO table  a
     USING table b
        ON (b.id = a.id)
WHEN MATCHED
THEN
   UPDATE SET
      a.col1 = b.col1,
      a.col2 = b.col2,
      a.col3 = 13
           WHERE  a.col3 = 6  AND
                      b.col4 ='N'
WHEN NOT MATCHED
THEN
   INSERT  VALUES  (b.col1, b.col2, b.col3)
       WHERE b.col4 = 'N'
Insert is working fine, the problem is with  the update conditions

WHERE  a.col3 = 6  AND
                      b.col4 ='N'

Although there are records to be updated  it is not updating.
it will only update the columns where the col3 = 6 and col4 = 'N' i hope you're aware about that.
 I'm working blind here and i don't have two tables to work with right now. I'll get home soon and get back to you as soon as i can.
Hopefully you will find the answer meanwhile.
if possible please provide some data to work with. Thanks.
