DB procedure in Merge Statement

Hi,
Is there any way to use DB procedure inside of Merge Statement.
Thanks & Regards

Wrap your procedure in a function to be accessible from within SQL.

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

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.

ORA 22813 in merge statement

hi gems..good afternoon...
My database version is 11.2.0.1.0 64 bit Solaris OS.
I am facing an "ORA-22813: operand value exceeds system limits" while running a procedure.
I have used loggers and found that it is getting failed in a MERGE statement.
That merge statement is used to merge a table with a collection. the code is like below:
MERGE /*+ INDEX(P BALANCE_HISTORIC_INDEX) */
    INTO BALANCE_HOLD_HISTORIC P
    USING TABLE(GET_BALANCE_HIST(V_MERGE_REC)) M
    ON (P.CUSTOMER_ID = M.CUSTOMER_ID AND P.BOOK_ID = M.BOOK_ID AND P.PRODUCT_ID = M.PRODUCT_ID AND P.SUB_BOOK_ID = M.SUB_BOOK_ID AND)
    WHEN MATCHED THEN
      UPDATE
         <set .....>
    WHEN NOT MATCHED THEN
      INSERT<.....>The parameter of the function GET_BALANCE_HIST(V_MERGE_REC) is a table type.
Now the function GET_BALANCE_HIST(V_MERGE_REC) is a pipelined function and we have used that because the collection V_MERGE_REC may get huge with data.
This proc was running fine from the beginning but from day before yesterday it was continously throwing ORA 22813 error in that line.
please help..thanks in advance..

hi paul..thanks for your reply...
the function GET_BALANCE_HIST is not selecting data from any tables.
What this pipeline function is doing is, it is taking the huge collection V_MERGE_REC as parameter and releasing its datas in pipelined form. The code for the functions is :
CREATE OR REPLACE FUNCTION GET_BALANCE_HIST(P_MERGE IN TAB_TYPE_BALANCE_HISTORIC)
RETURN TAB_TYPE_BALANCE_HISTORIC
PIPELINED AS
V_MERGE TAB_TYPE_BALANCE_HISTORIC := TAB_TYPE_BALANCE_HISTORIC();
BEGIN
FOR I IN 1 .. P_MERGE.COUNT LOOP
    V_MERGE.EXTEND;
    V_MERGE(V_MERGE.LAST) := OBJ_TYPE_BALANCE_HISTORIC(P_MERGE(I).CUSTOMER_ID,
                                             P_MERGE(I).BOOK_ID,
                                             P_MERGE(I).PRODUCT_ID,
                                             P_MERGE(I).SUB_BOOK_ID,
                                             P_MERGE(I).EARNINGS,
                                             P_MERGE(I).EARNINGS_HOUSE,
                                             P_MERGE(I).QUANTITY,
                                             P_MERGE(I).ACCOUNT_INTEGER);
END LOOP;
FOR J IN 1 .. V_MERGE.COUNT LOOP
    PIPE ROW(OBJ_TYPE_BALANCE_HISTORIC(V_MERGE(I).CUSTOMER_ID,
                                             V_MERGE(I).BOOK_ID,
                                             V_MERGE(I).PRODUCT_ID,
                                             V_MERGE(I).SUB_BOOK_ID,
                                             V_MERGE(I).EARNINGS,
                                             V_MERGE(I).EARNINGS_HOUSE,
                                             V_MERGE(I).QUANTITY,
                                             V_MERGE(I).ACCOUNT_INTEGER));
END LOOP;
RETURN;
END;I think the error is comming because of the parameter value of V_MERGE_REC. Since it is huge, so loading that into memory is causing problem. But in this case, how can I resolve it?? Can I use a global temporary table for this??
Please suggest...

ORA-00904 in Merge statement

I encountered with ORA-00904 in Merge statement. I fixed the error but I don't know why. Would you please help me explain it? Thanks in advance. The following is the detail description of my question.
I have two tables TBL_A<col1 integer,col2 integer> TBL_B<col1 integer,col2 integer> and an anonymous block to test executed in Oracle 10gR2.
DECLARE
V_NUM INTEGER;
BEGIN
V_NUM := 1;
/*merge I it's okay.the function of merge seems meaningless, please pay attention to its grammar*/
MERGE INTO TBL_A A
USING (SELECT V_NUM N, COL1, COL2 FROM TBL_B) B
ON (A.COL1 = B.N)
WHEN MATCHED THEN
UPDATE SET A.COL2 = B.COL2;
/*merge II*/
/*ora-00904*/
MERGE INTO TBL_A A
USING (SELECT V_NUM, COL1, COL2 FROM TBL_B) B
ON (A.COL1 = V_NUM)
WHEN MATCHED THEN
UPDATE
SET A.COL2 = B.COL2;
/*merge III is okay*/
MERGE INTO TBL_A A
USING (SELECT COL1, COL2 FROM TBL_B) B
ON (A.COL1 = V_NUM)
WHEN MATCHED THEN
UPDATE
SET A.COL2 = B.COL2;
COMMIT;
END;
I traced the 904 error and it seems the point is in the binding of variable V_NUM. But I don't know the exact reason. I think maybe it relates with the parse of PL/SQL. Would someone please help me or give me some hints?

hi,
When you saye,
   MERGE INTO TBL_A A
    USING (SELECT V_NUM,
                  COL1,
                  COL2
             FROM TBL_B) B
       ON (A.COL1 = V_NUM)
   WHEN MATCHED
   THEN
      UPDATE SET A.COL2 = B.COL2;
In the above for ON (A.COL1 = V_NUM)
oracle treats v_num as a variable in the procedure rather than v_num returned from using clause.
So you need to alias that.
MERGE INTO TBL_A A
    USING (SELECT V_NUM as somecol,
                  COL1,
                  COL2
             FROM TBL_B) B
       ON (A.COL1 = b.somecol)
   WHEN MATCHED
   THEN
      UPDATE SET A.COL2 = B.COL2;Edited by: Ganesh Srivatsav on May 12, 2011 11:42 AM
Added alias after peter pointed out for variable in the using.

Bogus Invalid Object in MERGE Statement

Let me begin by saying that I have been working with MERGE since its inception, and I am familiar with the fundamental gotcha's. This problem is more inexplicable. (It's one of those things that I expect, when someone explains it, will be a DOH! moment.)
I am building a one-time conversion script to merge an existing User table with a new User table. Since I am only in the development mode, I didn't want to modify the true table yet. So I made a copy of the table to work with, using the following familiar
syntax.
SELECT *
INTO uam.User2
FROM uam.[User]
Imagine my surprise when the MERGE statement refused to recognize uam.User2 - although it recognizes uam.[User] just fine.
In the interests of competeness, here is the MERGE Statement in question.
MERGE uam.[User2]
as tgt
USING (SELECT
UserID
,FirstName
,LastName
,CompanyID
,AuthenticationID
,isActive
,PrimaryEmailID
,CreatedByUserName
,CreatedByDtim
,@User
_User
,GETDATE()
_GETDATE
FROM #User
) as src
ON tgt.UserID = (src.UserID * -1)
WHEN NOT MATCHED
THEN
INSERT
(FirstName
,LastName
,CompanyID
,AuthenticationID
,isActive
,PrimaryEmailID
,CreatedByUserName
,CreatedByDtim
,LastUpdatedUserName
,LastUpdatedDtim
VALUES
(src.FirstName
,src.LastName
,src.CompanyID
,src.AuthenticationID
,src.isActive
,src.PrimaryEmailID
,src.CreatedByUserName
,src.CreatedByDtim
,_User
,_GETDATE
OUTPUT INSERTED.UserID
,tgt.UserID
INTO #UserMapping;
The procedure refuses to run, flagging the tgt.UserID as
Msg 4104, Level 16, State 1, Line 140
The multi-part identifier "tgt.UserID" could not be bound.
SSMS also flags the uam.[User2] on the MERGE line as "Invalid object name 'uam.User2'" on mouse-over.
A few notes:
I have a SELECT * FROM uam.User2 immediately before this MERGE, and it works just fine. And yes, it returns a UserID column.
If I change the name from uam.User2 to uam.[User], it works just fine.
I know the JOIN is a little strange (I really wanted just an INSERT where I could see the original UserID and the newly inserted UserID together, and INSERT will not let me OUTPUT directly from a table - hence the MERGE), but I also tried it with a straight-up
tgt.UserID = src.UserID. Nothing changed about the errors.
I also went back and re-created the uam.User2 table directly from the code that built uam.[User]. Nothing changed.
I'm flummoxed. This has all the earmarks of a "well-that-was-dumb" coding error, but for the life of me I cannot see what would change between using these two tables, since one is a copy of the other...
Any insight would be much appreciated!
Duncan Davenport

OK, I have it.
DOH! (told ya)
So, while intellisense (typically) flags this table as not existing, that's just Intellisense doing the nonsense it always does. This obfuscated the ACTUAL error - which was the wrong schema defined in the output clause. The error itself pointed at the wrong
line (nothing new there either). Once I fixed the OUTPUT clause, everything worked as expected - although SSMS is still putting squiggly red lines under everything that is working anyway. Yeah, we've all seen THAT behavior - no big deal.
Anyway, that's the answer. It's magic - in that the error messages specialize in misdirection :)...
Closing this. (I wonder if I get credit for answering my own question?)

Hello,
1.) why do you use dynamic SQL here? forms_ddl is a tricky one as it doesn't throw exceptions, so debugging is really fun. And I can't see any justification why this has to be dynamic SQL.
2.) put the whole thing in a stored procedure and call this procedure. write once, run everywhere.

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.

Indivual error recording in Merge Statement !!!!

Is it possible to record indivudual error in MERGE statement (Update / Insert).
I am unable to record those error. instead of MERGE if I update table in the cursor loop then I am able to record individual error but the process is time consuming.
Thanks in advance.

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..
BEGIN
v_sysdate:= pkg_utilities.fn_sysdate(1) ;
o_Error_Text := 'ORA-Error in updating end date in user_status table ';
tname:= 'user_status';
     MERGE INTO user_status r1
     USING (
          SELECT rowid rid , lead(start_period) OVER (PARTITION by user_id
          order by start_period)- 1 new_enddate FROM user_status ) r2
     ON ( r1.rowid = r2.rid )
     WHEN MATCHED THEN
     UPDATE SET end_period = new_enddate ;
     OPEN generic_cv4
     FOR SELECT
     user_id,user_status_type_id
     FROM user_status
     WHERE end_period IS NULL;
LOOP
FETCH generic_cv4 BULK COLLECT INTO
v_user_id_seq,
v_user_status_new
LIMIT p_array_size;
EXIT WHEN v_user_id_seq.COUNT = 0;
IF v_user_id_seq.COUNT > 0 THEN
     o_Error_Text := 'ORA-Error in update user_status type id in users table ';
     tname:= 'users';
FORALL I IN v_user_id_seq.FIRST..v_user_id_seq.LAST
UPDATE users
SET user_status_type_id = v_user_status_new(i),
last_upd_date = v_sysdate
WHERE user_id = v_user_id_seq(i);
END IF;
COMMIT;
END LOOP;
v_user_id_seq.delete;
v_user_status_new.delete;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('Error' ||sqlerrm);
DBMS_OUTPUT.PUT_LINE(o_Error_Text);
v_sql_err :=SQLERRM;
ROLLBACK;
pkg_champ_message_log.champ_message_log ('PKG_MIGRATE_V1_NESTED_MEMBER.p_update_member_status', tname, null,'Nested', v_sql_err,'Error',o_Error_Text,O_STATUS);
END;

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).

Merge statement

i would like to know if it is possible to identify the row that is causing the problem when you use a merge statement in pl/sql. i know if you create a cursor and then loop through the data you can identify the column but what about if i have only a merge that will either insert or update. is it possible to identify which row of data cause the problem? thanks

You can use an Error Logging Table<br>

Merge Statement in PL/SQL

Hi
I am using a merge statement where i am updating and inserting records in table 2 from table 1.
I want to log the no. of rows updated and new rows inserted in the log table.
If i am not wrong, we can use sql%rowcount but i need help as how to use this statement.
Please suggest a solution.
Thanks

Will the sql%rowcount will give the no. of updated rows OR no. of newly inserted rows OR the sum of both in case of a merge statement.Total number of rows that changed (SUM).

Question on passing string values to Partition clause in a merge statement

Hello All,
I am using the below code to update specific sub-partition data using oracle merge statements.
I am getting the sub-partition name and passing this as a string to the sub-partition clause.
The Merge statement is failing stating that the specified sub-partition does not exist. But the sub-partition do exists for the table.
We are using Oracle 11gr2 database.
Below is the code which I am using to populate the data.

I've not used partitioning, but I do not see MERGE supporting a variable as a partition name in
MERGE INTO (SELECT *
FROM stores_comm_mob_sub_info
SUBPARTITION (lv_subpartition_name)) T1
USING ... I suspect it is looking for a partition called lv_subpartition_name.
I also don't see why you need that partition name - the ON clause should be able to identify the partition's criteria.
