2 MERGE statements in same trigger - is it possible ?

Hi guys,
I have an After Insert trigger (on table A) that takes the last record from table A and insert/update it on another table (B) then insert /update in same table (B) some records which depends on it. When trying to insert data in table A, the trigger raise this error: ORA-04092: cannot COMMIT in a trigger.
I understand the error, but I need expert's opinion to make the trigger works.
Here is the actual situation:
Table A has a trigger on after insert, and BASED ON THE LAST ROW inserted (only this data is subject to the trigger's actions) does the following:
1. MERGE the data (last row from the source table=A) with the data from the table destination=B. This data is specific to an employee;
2. Open a cursor that goes through all the ancestors of the employee (I have an employees hierarchy) and MERGE the same data (but for ancestors) with the table destination;
To be more specific :
EmpID LOB Day Status
12 1007 29 Solved
EmpID has ancestors 24 and 95. Therefore in the destination table I will have to do:
1. Merge data for EmpID 12;
2. Merge data for EmpID 24, 95:
EmpID LOB Day Status
24 1007 29 Just S (this is the status for ancestors)
95 1007 29 Just S
Steps 1 and 2 are inside a PL/SQL procedure that works fine by itself, but not within the trigger (since there are many transactions on the destination table). These 2 steps are required because for EmpID 12 I set a status and for the ancestors I set up a different status (this was the only way I could think of).
Can someone give me a hint how should I handle this situation ?
Thank you,
John

Based on my understanding of what you are trying to do you are going about this in the wrong way. Try this approach instead:
1. Trigger fires initiating the process and passes relevant :NEW values to a stored procedure
2. The stored procedure does all the work and possibly should be an autonomous transaction
It looks very much like your code just doesn't belong in a trigger.
PS: Why a MERGE statement? If the rows most likely do not exist then INSERT and UPDATE in your exception handler: Otherwise UPDATE as the default and INSERT in the exception handler. It is not very likely the percentage of inserts and updates will be near 50% each.

Looping thru merge statement

I have a merge statement, this executes for all the rows when the procedure is executed. Here i would like to include this merge statement as the part of LOOP so that all records will not get updated for a one time.
how can i change this merge statement to include as the part of LOOP here.
the user id should be the key to update the table USERS in merge statement, the same user id is exists in the bulk collect too..

Now lets talk how can i keep this merge statemnet as the part of the loop. It seems your mind is made up.
Unfortunately, what you're asking makes no sense at all. You can't "loop through a merge statement".
If you don't want to use merge for the entire table at once, the only thing you can do is to break up the table in your USING clause by some sort of range (maybe an account number or whatever). You could then run your code for each range (or even run them in parallel).
The only other option is to not use MERGE at all and duplicate the logic of it within your loop (which is what I said in my first response).

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 :-
ORA-01446: cannot select ROWID from, or sample, a view with DISTINCT, GROUP BY, etc.
rather then the ora-01733 error I get in the real code ( which is an update from an involved

Error executing a stored procedure from SSIS using the MERGE statement between databases

Good morning,
I'm trying to execute from SSIS a stored procedure that compares the content of two tables on different databases in the same server and updates one of them. To perform this action, I've created a stored procedure in the destination database and I'm
comparing the data between tables with the MERGE statement. When I execute the procedure on the destination database the error that I obtain is:
"Msg 916, Level 14, State 1, Procedure RefreshDestinationTable, Line 13
The server principal "XXXX" is not able to access the database "XXXX" under the current security context."
Some things to take in account:
1. I've created a temporary table on the same destination database to check if the problem was on the MERGE statement and it works fine.
2. I've created the procedure with the option "WITH EXECUTE AS DBO".
I've read that it can be a problem of permissions but I don't know if I'm executing the procedure from SSIS to which user/login I should give permissions and which.
Could you give me some tip to continue investigating how to solve the problem?
Thank you,
Virgilio

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,
                               a.process_status = b.process_status,
                               a.time_process = case a.process_status
                                                  when b.process_status then a.time_process
                                                  else b.time_process
                                                end
when not matched then insert(
                               a.id,
                               a.name,

Problem in Merge statement

Hi All,
I am using merge statement to update 30000 records from the tables having 55 lacs records.
But it is taking much time as i have to kill the session after 12 hours,as it was still going on.
If,Same update i m doing using cursors,it will finish in less than 3 hours.
Merge i was using is :-
MERGE INTO Table1 a
USING (SELECT MAX (TO_DATE ( TO_CHAR (contact_date, 'dd/mm/yyyy')
|| contact_time,
'dd/mm/yyyy HH24:Mi:SS'
) m_condate,
appl_id
FROM Table2 b,
(SELECT DISTINCT acc_no acc_no
FROM Table3, Table1
WHERE acc_no=appl_id AND delinquent_flag= 'Y'
AND financier_id='NEWACLOS') d
WHERE d.acc_no = b.appl_id
AND ( contacted_by IS NOT NULL
OR followup_branch_code IS NOT NULL
GROUP BY appl_id) c
ON (a.appl_id = c.appl_id AND a.delinquent_flag = 'Y')
WHEN MATCHED THEN
UPDATE
SET last_contact_date = c.m_condate;
In this query table 1 has 30000 records and table2 and table 3 have 3670955 and 555674 records respectively.
Please suggest,what i am doing wrong in merge,because as per my understanding merge statement is much better than updates or updates using cursors.

For one thing, alias your tables and use that in the column specifications (table1.column1 = table2.column3 for example)...
      SELECT
         DISTINCT
            acc_no acc_no
      FROM Table3, Table1
      WHERE acc_no            = appl_id
      AND   delinquent_flag   = 'Y'
      AND   financier_id      = 'NEWACLOS'We don't know what your tables look like, what columns come from where. Try and help us help you, assume we know NOTHING about YOUR system, because more likely than naught, that's going to be the case.

As of Oracle 10 the MERGE command allows for insert, update and delete operations.

FORALL MERGE statement works in local database but not over database link

Given "list", a collection of NUMBER's, the following FORALL ... MERGE statement should copy the appropriate data if the record specified by the list exists on both databases.
forall i in 1..list.count
merge into tbl@remote t
using (select * from tbl
where id = list(i)) s
on (s.id = t.id)
when matched then
update set
t.status = s.status
when not matched then
insert (id, status)
values (s.id, s.status);
But this does not work. No exceptions, but target table's record is unchanged and "sql%rowcount" is 0.
If the target table is in the local database, the exact same statement works:
forall i in 1..list.count
merge into tbl2 t
using (select * from tbl
where id = list(i)) s
on (s.id = t.id)
when matched then
update set
t.status = s.status
when not matched then
insert (id, status)
values (s.id, s.status);
Does anyone have a clue why this may be a problem?
Both databases are on Oracle 10g.

Should throw an error in my opinion. The underlying reason for not working is basically because of
SQL> merge into   t@remote t1
     using   (    select   sys.odcinumberlist (1) from dual) t2
        on   (1 = 1)
when matched
then
   update set i = 1
Error at line 4
ORA-22804: remote operations not permitted on object tables or user-defined type columnsSame reason as e.g.
insert into t@remote select * from table(sys.odcinumberlist(1,2,3))doesn't work.

Merge Statement in ABAP

Dear Gurrus,
i am having a trouble in using oracle merge statement in abap, the moment i use where clause in the bottom it gives me an oracle error
EXEC SQL.
MERGE INTO SAP_GL_ACCOUNT@GETZDB a
USING SKA1 b
    ON (A.gl_code= B.SAKNR)
WHEN MATCHED THEN
    UPDATE SET a.posting_block = B.XSPEB,
               a.locked        = B.XSPEA,
               A.BALANCE_SHEET = B.XBILK
     WHEN NOT MATCHED THEN
       insert   (gl_code,
                 DESCRIPTION,
                 posting_block,
                 locked,
                 balance_sheet)
      VALUES (b.SAKNR,'shadab',B.XSPEB,B.XSPEA,B.XBILK)
      where b. mandt = 950      I am talking about this line
         ENDEXEC.
the Moment i include WHERE clause in the botton before ENDEXEC it generates as error
" Database error text........: "ORA-00904: "A3"."MANDT": invalid identifier#ORA-02063: preceding line from GETZDB".
although its a basic feature of Oracle to inclue where clauses in insert or update in merge, but here it is generating an error.

Hello Shadab,
As per my understanding of this oracle native sql code.
everything is fine except the use of direct value i.e 950 .
System is not able to process this value .
This normally happens even in normal abap sql statements also.
The better solution could be to declare a variable with the
same data type as "mandt" and then pass this "950" value into that
variable and then use this variable in the where clause instead of directly
passing the value.
i.e data:l_var type mandt vlaue '950'.
The other option could be to use the same hard coded
value but use this value in the where clause in quotations i.e.,
'950' instead of 950.
I hope this would solve your purpose, If not please reply me back.
thanks,
M.Naveen Kumar.

Problem using TAPI triggers and merge statement

Hi,
I use Designer tapi triggers on a table. When I try to execute a merge statement, I get the following error:
ORA-06502: PL/SQL: numeric or value error: NULL index table key value.
Is there a restriction when using TAPI triggers and merge statements that anyone is aware of?

No restrictions on MERGE commands that I know of. I have, however, seen the TAPI give inexplicable ORA-06502 errors. It would help to know what line in which procedure or trigger gave the error. That information should have been in the error stack.

Problem in merge statement -ORA-27432 Step does not exist for chain

Hi
I m getting ORA-27432 Step does not exist for chain error in merge statement.Please explain the same.

                          A.ADDUIDTIME)This query is a short version of the main query.It is same but having 180 columns in original table.

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 logging in merge statement

how to handle error logging in merge statement??
thanks in advance!!!

Welcome to the forum!
Whenever you post please provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).
>
how to handle error logging in merge statement??
>
Do it the way the documentation tells you to.
See the error_logging_clause of the MERGE statement in the SQL Language doc
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_9016.htm
It contains an example of using error logging with MERGE
>
error_logging_clause
The error_logging_clause has the same behavior in a MERGE statement as in an INSERT statement. Refer to the INSERT statement error_logging_clause for more information.
See Also:
"Inserting Into a Table with Error Logging: Example"

Order not maintained in MERGE statement

I am using a MERGE statement as follows:
MERGE INTO target T
USING ( select * from source order by data_id ) S
on ( T.data_id = S.data_id )
when matched then update
set t.code = s.code
when not matched then insert
(t.code, t.data_id )
values
(S.code, S.data_id )
But the newly inserted records in the target table are not ordered in the same order as the source table.
E.g
source
data_id(pk)     code
1     1
2     2
3     2
target
pk_col data_id     code
1     3     1
2     1     2
3     1     2
I was expecting records in noth tables to be sorted in order of data_id
Is this a limitation of merge statement or is there any workaround.

Merge Statement !!!! difference in Oracle 9i and Oracle XE

Hi All ,
I am using a Merge statement for multiplying a column......which works fine in XE but not in Oracle 9i
CODE
*======*
MERGE INTO MULTIPLY T USING
(SELECT CONV,ITEM FROM MULTIPLY WHERE TYP='P') X ON
(T.ITEM= X.ITEM)
WHEN MATCHED THEN UPDATE SET T.CONV =X.CONV * T.CONV WHERE TYP!='P'
What shud I need to do in order to get the same result in Oracle 9i.....
I understand that I used use one more line WHEN NOT MATCHED ..... but I am getting an Error in the Update statement where clause , whether it is not possible to combine where clause in the Merge statement
Sample data:
ITM     CONV     TYP
===============
A     2
A     5
A     4     P
A     2
Output; which I am getting in Oracle XE but not in Oracle 9i
======================================
ITM CONV TYP
=== ==== =====
A 2 *4
A 5 *4
A 4 P
A 2*4
