Help in Update Statement

Hi All,
I would like to create an update statement which produces the desired result(below) but find that the update statement I have created does not perform.
<pre>
CREATE TABLE RACE(
S_ID NUMBER,
D_PID VARCHAR2(15),
OCCURENCE NUMBER);
</pre>
<pre>
insert into RACE
values(1,'HYD01',null);
insert into RACE
values(2,'HYD01',null);
insert into RACE
values(3,'HYD01',null);
insert into RACE
values(4,'HYD02',null);
insert into RACE
values(5,'HYD02',null);
insert into RACE
values(6,'HYD03',null);
</pre>
<pre>
CREATE TABLE RACE_LOOKUP_CNT AS
select d_pid,count(s_id)occurence
from race
GROUP BY d_pid;
</pre>
--Need to update the RACE table as
S_ID DPID OCCURENCE
1 HYD01 3
2 HYD01 3
3 HYD01 3
4 HYD02 2
5 HYD02 2
6 HYD03 1
Tried this subquery but kept getting multiple rows update.
<pre>
update RACE c
set
c.occurence = (
select (a.occurence)
from RACE_LOOKUP_CNT a
where a.occurence in
select occurence
from RACE b
AND a.d_pid =c.d_pid);
</pre>
Thank you all.

Help on update statement in Apply DML Handler

I followed the example given in Streams document.
The document has the code for converting DELETE on the source to INSERT on the target. I added the dml handler code INSERT and UPDATE statements also.
In DELETE, INSERT, UPDATE dml handler code, I am setting the command type to 'INSERT' so that I can insert the data in the target table.
It is working fine for DELETE and INSERT statements.
When I do update on the source table,
I see only the value for the column I updated and all other columns are showing blank. May be this is the normal behaviour. How do I see the values for entire record. Do I need to join the source table based on the key column to get the data for the columns that were not updated.
Also, I thought I should at least see the values for key column and updated column in the target table. It only shows the value for updated column but not for key column. But, When I choosed the old values (I know we need new values, but I just did it for test purpose) in the UPDATE DML handler, it shows the values for key column and the updated column.
When I read the data in the LCR record using get_value('old', 'EMPLOYEE_ID') and get_value('NEW', 'FIRST_NAME')
for key column, it shows the value in both old and new. I do not understand why it is not inserting the key column value in the target table.
Thanks for your help in advance.
Best regards,

I forgot to mention these things.
We added supplmental logging using alter database add supplemental log data (primary key, unique index) columns;
I also added the supplemental logging on the source key column (employee_id) using ALTER TABLE emp ADD SUPPLEMENTAL LOG GROUP log_group_emp_pk (employee_id) ALWAYS;
I also set the key column on the target table using DBMS_APPLY_ADM.SET_KEY_COLUMNS.
Thanks for your help in advance.
Best regards,

Need help with update statement with multiple joins

I've got the following select statement that is pulling 29 records:

Help on update statement

Hi, Please help me on the following update scenario
I have a column in a table PRD_NM which is a not null column.. I want to update this column with a set of values from another query..
UPDATE Table1 tg
set PRD_NM=(select PRD_NM from( select prd_nm,state,item_no,bar_code from products) sr
where tg.state=sr.state and tg.item_no=sr.item_no and tg.bar_code=sr.bar_code
and tg.PRD_NM='NA')
basically i want to update all those PRD_NM with value 'NA' to the value coming from the source query...
but when I run the statement I am getting an error saying that the PRD_NM cannot be set to null... But here I am not considering anything that can be a null when updated.
Please help with any idea...

Hi,
If you can't UPDATE via an in-line view (as Someoneelse suggested), and you don't want to basically do the same query twice (once in the scalar sub-query, then again in an EXISTS subquery, as in Someoneelse's next to last message), you can use MERGE:
MERGE INTO     Table1     tg
USING     (     SELECT     prd_nm, state, item_no, bar_code
          FROM     products
     )          sr
ON     (     tg.state     = sr.state
     AND     tg.item_no     = sr.item_no
     AND     tg.bar_code     = sr.bar_code
     AND     tg.PRD_NM     = 'NA'
WHEN MATCHED THEN
     UPDATE     SET     tg.prd_nm     = sr.prd_nm;Without copies of your tables and data, I can't test.

Need help in update statement

hi,
how can i achieve the following logic
I have table ABC with column A varchar(20), B(int), C(varchar(20))
if A is null and B is valid number then C has to be updated with 'text'
if A is valid text and B is null then C has to be updated with 'number'
if A is valid text and B is valid number then C has to be updated with 'text-number'
thanks in advance

First Update
UPDATE ABC
SET C= 'text'
where A is null;since B is int data type it will always storeintegeres hence check not required.
Second Update
UPDATE ABC
set C = 'number'
where A is not null
and B IS NULLThird Update
UPDATE ABC
SET C = 'number-text'
WHERE A IS NOT NULL;Hope this answers.
You can get this in single update too
AND B IS NOT NULL

Help with update statement

Create table temp_sibs as
(select 1701 sib_1, 1702 sib_2 from dual
union all
select 1171,1172 from dual
union all
select 1701,1172 from dual
union all
select 1171,1174 from dual
union all
select 1173,1176 from dual
union all
select 2001,2004 from dual
union all
select 2001,2006 from dual
union all
select 2002,2006
from dual)
create table temp_sib_data as
(select 111 pid, 1701 sibid, 5 amt from dual
union all
select 111 pid, 1176 sibid, 5 from dual
union all
select 222 pid, 2006 sibid, 5 from dual
union all
select 333 pid, 2001 sibid, 5 from dual
union all
select 333 pid, 2002 sibid, 5 from dual
union all
select 333 pid, 1171 sibid, 5 from dual
First table is a lookup table that defines relationships sib_1 is related to sib_2
Second table consists of a column pid and column sibid which is either sib_1 or sib_2
The user would pass parameter pid and sibid and I want to update all the related rows with any matching sibid to 0.
It is like 1701 matches with 1702 and 1701 matches with 1174 so indirectly 1701 and 1174 match...and 1171 matches because
1171 matches with 1174
so all 1701,1702,1171,1172, 1173,1174,1176 match (indirectly with each other)
So for example if the user passes 333 pid and 2001 rows with 333,2001 and 333,2002 should update the amt to 0
and if the user passes 111 and 1176 than 1st 2 rows should be updated to 0.

Hi,
try this:
DEFINE PID='333'
DEFINE sibid='2001'
-- SELECT is only for test.
-- Replace SELECT with: UPDATE TEMP_SIB_DATA SET AMT = 0
SELECT * FROM TEMP_SIB_DATA
WHERE PID = &PID   AND SIBID IN (
       WITH TEMP AS(
            SELECT SIB_1, SIB_2 FROM TEMP_SIBS
               START WITH     SIB_1 = &&SIBID   OR SIB_2 = &&SIBID
               CONNECT BY NOCYCLE      PRIOR SIB_2 = SIB_1
                                   OR PRIOR SIB_1 = SIB_2
                                   OR SIB_2 = PRIOR SIB_2
                                   OR SIB_1 = PRIOR SIB_1
        SELECT SIB_1 FROM TEMP
        UNION ALL
        SELECT SIB_2 FROM TEMP
);For pid=333 and sibid=2001 it returns desired records for update:
PID                    SIBID                  AMT
333                    2001                   5
333                    2002                   5For pid=111 and=1176 it returns one row - 1176 matches only with 1173 and 1173 doesn't match with any other rows,
so only 5th row, not first 2, should be updated ... maybe I missed something ?
PID                    SIBID                  AMT
111                    1176                   5

Sender JDBC: help to construct Update statement

Hi,
I need help in writing a update statement to DB2 database in sender JDBC adapter.
The sender adapter picks up only few records say 10 at a time which match the Select query condition. So I would need to update only those selected "n" records and not all the records that match the Select query condition.
Select looks like :
Select * from <table> where <condition> fetch first <n> rows only.
But it is not allowing the following update
update <table> set <field> = <value> where <field> IN (Select * from <table> where <condition> fetch first <n> rows only)
The above statement errors because DB2 does not allows u201CFetchu201D statement within the update sub query.
Any pointers to a write update statement for n records is highly appreciatedu2026
~SaNvu2026

Hi Santosh,
In JDBC Sender Adapter provide the following select & update statements
Select Statement:
select * from <table> where <condition> AND ROWNUM<N (N==No.of Rows)
Update Statement:
update <table> set <field> = <value> where <field> IN (Select * from <table> where <condition> AND ROWNUM<N)
(N==No.of Rows)
And for the error you are facing is because of the server communication link failure between the two systems.
Check the connections and try to stop & start communication channels once.

Help with doing SELECT sub query within the SET of an UPDATE statement

After doing some research, it appears as if it's possible to use a SELECT subquery in the SET of an UPDATE statement. i did find some examples and here is my code, however when I click the "check" button it's saying the field (my entire select subquery) is unknown and neither in one of the specified tables or defined by a "DATA". Do I have a syntax issue or is there another reason why it's not taking this as a valid statement? Thanks for the help!
LOOP AT IT_DATA
UPDATE /BIC/AZDP_O0140
   SET /BIC/ZCOUNTER = (SELECT COUNT( DISTINCT MATERIAL )
                        FROM /BIC/AZDP_O0140
                        WHERE MATERIAL EQ IT_DATA-MATERIAL
                        GROUP BY MATERIAL).
ENDLOOP.

my Update does indeed have a WHERE clause but because of the issue i'm having, all my criteria in my WHERE is black text in the ABAP editor. The editor doesn't even recognize the keywords "WHERE" or "EQ". Below is my entire statement which contains all WHERE criteria in both the Update and the Subquery, i've just removed it for testing to help simplify the query and eliminate as many other factors as posisble that may be causing problems:
LOOP AT IT_DATA.
   UPDATE /BIC/AZDP_O0140
   SET /BIC/ZCOUNTER = (SELECT COUNT( DISTINCT MATERIAL ) FROM /BIC/AZDP_O0140
   WHERE WHSE_NUM EQ IT_DATA-WAREHOUSE
    AND PLANT EQ IT_DATA-PLANT
    AND /BIC/ZTRAN_NO EQ IT_DATA-TRANS_NUM
    AND DELIV_NUMB EQ IT_DATA-DELIVERY
    AND MATERIAL EQ IT_DATA-MATERIAL
    GROUP BY MATERIAL)
   WHERE WHSE_NUM EQ IT_DATA-WAREHOUSE
    AND PLANT EQ IT_DATA-PLANT
    AND /BIC/ZTRAN_NO EQ IT_DATA-TRANS_NUM
    AND DELIV_NUMB EQ IT_DATA-DELIVERY
    AND MATERIAL EQ IT_DATA-MATERIAL.
ENDLOOP.
i should also mention the sources i found were not within the SAP Library but instead on other third-party ABAP websites. so because i was having issues i wanted to post here to see if anyone else has come up with a working solution. but if this cannot be done i can likely come up with a solution for my needs using multiple internal tables, this would just have been much easier since i can get a query like this to do what i want in SQL Server. Thought i could utilize this in ABAP as well.

But when we are using the where condition it should update records with the matching ids. right?What your query should do is entirely up to you; I can't answer any questions about that, only you can.
I have faced this issue earlier.
WHERE       tmpuser.emp_id = employee.emp_idCan you explain?Not out of context. Post a complete statement.
If this isn't directly related to user9170886's problem, then it's better to start your own thread.
I can say a few things about UPDATE statements in general:
The WHERE clause governs which rows will be UPDATEd. If there is no WHERE clause, all rows in the table will be UPDATEd.
So
UPDATE     employee
SET     employee_name = ( <subquery> )
;UPDATEs every row in employee, because the UPDATE statement does not have a WHERE clause. Nothing in the sub-query can change that.
A sub-query can reference values from its immediate parent, but a parent can't reference values from a sub-query (other than the values actually returned by the sub-query, of course).
So
UPDATE     employee
SET     employee_name = ( <subquery> )
WHERE     tmpuser.emp_id     = employee.emp_id
;causes an error, because there is no table called tmpuser in the main UPDATE statement. Nothing in the sub-query can change that.

Update statement help

Hello folks,
I need some help/advise on an UPDATE statement.
I have two tables. I need to join these tables and update a field in table1 with a field from table2.
Please see the attached jpg file.
The first 3 coloumns are from table1 and last 2 columns in the picture are from table2.
I want to update NEXT_RATE_RESET_ADJ_P field (from table1) with NEXT_RESET_DATE_ADJUSTED field (from table2). I want to join them between table1.DEAL_LEG_ID_P and table2.DEAL_LEG_ID.
I have never written update statement with a join in it.
Any help is greatly appreciated.

UPDATE EMP1
SET EMP1.SAL =
(SELECT EMP2.SAL
FROM EMP2
WHERE EMP1.EMPNO = EMP2.EMPNO
AND EMP1.DEPTNO = EMP2.DEPTNO)
WHERE EMP1.JOB = 'SALESMAN';
To avoid setting EMP1.SAL to NULL if there is no matching EMP2 record
UPDATE EMP1
SET EMP1.SAL =
(SELECT EMP2.SAL
FROM EMP2
WHERE EMP1.EMPNO = EMP2.EMPNO
AND EMP1.DEPTNO = EMP2.DEPTNO)
WHERE EMP1.JOB = 'SALESMAN'
AND EXISTS (SELECT NULL
FROM EMP2
WHERE EMP1.EMPNO = EMP2.EMPNO
AND EMP1.DEPTNO = EMP2.DEPTNO);

2 errors
But when I remove the update statements and just try to display the TITLE of this node, I dont see any outputs. Please help me to catch up with my mistakes. Below is source code I am using to run this functionality.
Thanks.

Thanks Rucong. The change you suggested did helped me to run the program correct. But I also have the display function to retrive the results and my program is parsed without any output.

See there is no OUPUT displayed. Is there somethinglike a 'print' I have to use in this java code.

Help with this update statement..

Hi everyone,
I am trying to update a column in a table .I need to update that column
with a function that takes patient_nbr and type_x column values as a parameter.
That table has almost "300,000" records. It is taking long time to complete
almost 60 min to 90 min.
Is it usual to take that much time to update that many records?
I dont know why it is taking this much time.Please help with this update statement.
select get_partner_id(SUBSTR(patient_nbr,1,9),type_x) partner_id from test_load;
(it is just taking 20 - 30 sec)
I am sure that it is not the problem with my function.
I tried the following update and merge statements .Please correct me if i am wrong
in the syntax and give me some suggestions how can i make the update statement fast.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);
merge into test_load a
using (select patient_nbr,type_x from test_load) b
on (a.patient_nbr = b.patient_nbr)
when matched
then
update
set a.partner_id = get_partner_id(SUBSTR(b.patient_nbr,1,9),b.type_x);
there is a index on patient_nbr column
and the statistics are gathered on this table.

Hi Justin,
As requested here are the explain plans for my update statements.Please correct if i am doing anything wrong.
