Help for merge statement?

I have a problem in Merge statement. My merge statement is following:
MERGE INTO hoadon hd
USING (
SELECT m.ma_ttoan, t.ma_ttoan ma_kh
FROM tai_anhxa_makh t
INNER JOIN hoadon m on t.ma_kh = m.ma_ttoan
WHERE m.thang_nam = '200908' and m.ma_ttoan not like 'DLC%' and t.ma_ttoan IS NOT NULL
GROUP BY m.ma_ttoan, t.ma_ttoan
) m ON (hd.ma_ttoan = m.ma_kh)
WHEN MATCHED THEN
UPDATE SET ma_ttoan = m.ma_ttoan
WHEN NOT MATCHED THEN
INSERT (thang_nam, ma_ttoan) VALUES('200908','thaodv')
After execute this query, PS/SQL show error message: "ORA-00904: hd.ma_ttoan invalid identifier"
I'm using Oracle version 9i
Can anyone help me to resolve this problem?
Thanks in advance

In 9i you can't use the columns from the ON clause in your UPDATE part of the MERGE statement
this is invalid:
UPDATE SET ma_ttoan = m.ma_ttoanuse a different column here.

Need Help for MERGE statement

I have a MERGE statement, I am executing it from shell script, I want to print that how many rows has been updated and Inserted.
Can any one give me some idea.
Thanks in Advance

I want to print that how many rows has been updated and Inserted. If you really want/need to print that information, then don't use MERGE but INSERT and UPDATE statements.

         GROUP BY commitment_num, sap_cust_num, sales_org, batch_id;

You can use MERGE to update some rows and delete others. Here's the code, then I will explain.MERGE INTO stg_tables o
using (
SELECT rid, rn, sum_credit_amount FROM (
    SELECT ROWID rid,
    count(*) OVER(PARTITION BY commitment_num, batch_id) cnt,
    row_number()
     over(PARTITION BY commitment_num, batch_id order by handshake_date desc) rn,
    sum(credit_amount)
     OVER(PARTITION BY commitment_num, batch_id) sum_credit_amount
    FROM stg_tables A
    WHERE batch_id IN('2806','2805')
WHERE cnt > 1
) n
ON (o.ROWID = n.rid)
WHEN MATCHED THEN UPDATE SET credit_amount = sum_credit_amount
delete where rn > 1;Look at the inner query in the USING clause: CNT is the number of rows having the same commitment_num and batch_id. RN numbers those rows, with 1 for the newest row. I also get the credit amount sum and the ROWID of the row.
Now for the outer query in the USING clause: I only keep the rows with CNT > 1, because the others don't need to be merged. This is important, because you don't want to be updating rows that are already OK.
Now the MERGE statement matches the table and my USING clause on ROWID, which can be very efficient. It updates all the rows with the new credit amount, but then it DELETEs all the rows but the most recent one.
If you run the MERGE twice, you will see that the second time it merges "0 rows". No unnecessary updates!

Instead of trigger is NOT firing for merge statements in Oracle 10gR2

The trigger fires fine for a update statement, but not when I use a merge statement
with an update clause. Instead I get the normal error for the view ( which is a union all view, and therefore not updatable.)
The error is :-
ORA-01733: virtual column not allowed here
oracle release is 10.2.0.2 for AIX 64L
Is this a known bug ?
I've used a multi-table insert statement to work around the problem for inserts, but
for updates, I'd really like to be able to use a merge statement instead of an update.
Mark.

This is my cut-down version :-
In this case case I'm getting an :-

rather then the ora-01733 error I get in the real code ( which is an update from an involved

Syntax for Merge statement to insert into target and update source

Hello All,
I want to use Merge statement to insert records when not matched in my target and update records in source when matched. Is it possible to do using Merge statement.
create table a (aa number)
create table b (bb number)
alter table a add flg char(1)
merge b as target
using a as source
on (target.bb = source.aa)
when matched then
update set source.flg = 'Y'
WHEN NOT MATCHED THEN
insert (target.bb)
values
(source.aa)
Thanks.

Hi,
I have no idea about the version of DB, else some new features with respect version can be specified - just for informaitve purpose and to post across the verison of DB in future posts.
Coming to your issue and requirement.
if you check the syntax and functionality , then its on Merge on target base only - with respect to Update (matched o columns) and insert (for unmatched columns). Source - as the term is clear. It might not work out on source table.

Need help for sql statement

Hi,
Need help to write sql statement.
create table t_dt ( dt_start date, dt_end date, amount number);
insert into t_dt values('1-Jan-10','10-Feb-10',12);
insert into t_dt values('11-Feb-10','10-Mar-10',10);
insert into t_dt values('11-Mar-10','20-Apr-10',8);
insert into t_dt values('21-Apr-10','28-Jun-10',10);
insert into t_dt values('29-Jun-10','20-Sep-10',10);
insert into t_dt values('21-Sep-10','10-Oct-10',10);
insert into t_dt values('11-Oct-10','31-Dec-10',8);
insert into t_dt values('1-Jan-11','10-Feb-11',8);
insert into t_dt values('11-Feb-11','10-Mar-11',7);
insert into t_dt values('11-Mar-11','20-Apr-11',6);
insert into t_dt values('21-Apr-11','28-Jun-11',6);
insert into t_dt values('29-Jun-11','20-Sep-11',6);
insert into t_dt values('21-Sep-11','10-Oct-11',4);
insert into t_dt values('11-Oct-11','31-Dec-11',8);
Result should be like below..
dt_start     dt_end     Amount
1-Jan-10     10-Feb-10     12
11-Feb-10     10-Mar-10     10
11-Mar-10     20-Apr-10     8
21-Apr-10     10-Oct-10     10
11-Oct-10     10-Feb-11     8
11-Feb-11     10-Mar-11     7
11-Mar-11     20-Sep-11     6
21-Sep-11     10-Oct-11     4
11-Oct-11     31-Dec-11     8
Just to explain the example, take a row with start date as 21-Apr-10 in the above insert statements, since it has the same amount for next two rows (i.e. with start date '29-Jun-10' and '21-Sep-10') these 3 rows should be converted to represent only 1 row in the result and the start date and end date should be changed per the result shown above.
Thanks.

I seem to recall this error being spuriously (well unhelpfully) thrown if you tried to UPDATE a key that you used in the ON clause, but I could be mistaken.
For us to recreate this you would need to supply the exact version and scripts to create the tables in question.

MERGE statement without INSERT clause....is possible...?

Hi everybody...
MERGE statement without UPDATE or INSERT clause is possible or not
I want to select from one table and update in another table. So i dont want insert statement and i want to do it in single query....possible solutions are requested.
Thanks in advance
pal

Hi..
Thanks for ur reply. For MERGE statement, we have to give UPDATE and INSERT clause. this MERGE statement works without INSERT or UPDATE clause.
Why i am asking is, I want to select how many rows (count(*)) from table1 and based on this count, i have to update in table2
Both tables r different and for select and for update where clauses are different. Both tables r totally different.
I want to do it in single query, so i asked this is possible with MERGE statement without INSERT clause.
Thanks for ur reply

Help needed in MERGE statement

Hi,
I am new to PL/SQL, I want to update a table called "final_test" based on the below query result.
1. I want to check whether that particular record is present or not in my "final_test" table.
2. If its present in the "final_test" table and the process_status got changed then I want to update that alone in my "final_test" table.
3. If its not present then I want to insert that record into my "final_test" table.
Basically I am retrieving the report and its status for a particular date.
select
b.id,
a.name,
a.t_name,
c.process_status,
c.time_process
from rep_tab_map a, j_tab_map b, proc_status c
where a.t_name=b.t_name
and b.id=c.id (+)
and trunc(c.date_start)=trunc(sysdate -1)
group by a.name,b.id,c.process_status,c.time_process,a.t_name
order by 2
I thought of using Merge statement but i am not sure what i have to use in ":USING" and "ON" clause.
Please help me with MERGE or with someother way.
Thanks

Assuming final_test has same structure as select list in your query:
merge
into final_test a
using (
         select b.id,
                 a.name,
                 a.t_name,
                 c.process_status,
                 c.time_process
           from rep_tab_map a,
                 j_tab_map b,
                 proc_status c
           where a.t_name=b.t_name
             and b.id=c.id(+)
             and trunc(c.date_start)=trunc(sysdate -1)
           group by a.name,b.id,c.process_status,c.time_process,a.t_name
        ) b
on (b.id = a.id)
when matched then update set a.name = case a.process_status
                                          when b.process_status then a.name
                                          else b.name
                                        end,
                               a.t_name = case a.process_status
                                            when b.process_status then a.t_name
                                            else b.t_name
                                          end,

What version of Oracle are you using? This message does not appear in my 10.1 Error Messages document, but the other messages in that range seem to be about DBMS_SCHEDULER.
Are you using scheduler somewhere around where you are getting the error message?

Error in Merge statement for Oracle 10gR2

Hi,
When I use the MERGE statement to copy data across a database link (from 10gR2 to 10gR2 database), if I have both an update and insert clause it works fine, but if I omit the insert clause and have just update on its own, I get error "ORA-02064: distributed operation not supported".
Can anyone help on this

This came up in a thread last week, the 10g versions of MERGE (without INSERT or with DELETE) did not appear to work over DB links.
