Update Query using Toplink

I would like to fire an update query using Toplink mapping objects. The
structure of the Query would be like
update <<table name>>
set <<col name A>> = 'Y'
where <<col name B>> in (<<valA>>,<<valB>>............);
ValA, ValB.... are dynamic values passed from my front end Java App
Can anyone help me in this regard...........
Thanks
Karthik

Karthik,
This is new functionality added in 10.1.3. You will want to look at UpdateAllQuery.

How Can Improve On Slow Update Query Using /*+ NO_XML_DML_REWRITE */?

We have an update query recently brought to my attention that is running extremely slow on Oracle 11.2.0.1 against a secure file binary XML table using
update /*+ NO_XML_DML_REWRITE */croutreach.action set object_value = :1 where actn_id = :2 .
I am told the majority/near majority of the ~ 16 fields are updated. Also this table has numerous predefined virtual columns with fn based indexes on them.
My first inclination was to recast this using the Oracle updatexml function. I was told, the /*+ NO_XML_DML_REWRITE */ hint would also be necessary here.
update /*+ NO_XML_DML_REWRITE */
<tble_name> a
set a.object_value = updatexml(a.object_value ...).
Last year our dba's were instructed by Oracle Support to use this hint, as the update wasn't updating any records w.o any error msgs.
+1. Hoping to find out if anyone has run across using this hint in some capacity and what was their experience?+
In trying to optimizie this update statement, I'll start from scratch not using the /*+ NO_XML_DML_REWRITE */ hint and will commence with using the updatexml function with setting up an xmlindex.
+2. Hoping to receive some suggestions on creating the proper xmlindex - figuring an unstructured index. If get some good performance with the xmlindex; hoping to retire some of the virtual column usage.+
+3. Any suggestions on living with virtual columns in conjunction with xmlindexes? See the action table definition and associated ivirtual columns and indexes. This table seems over indexed...+

update /*+ NO_XML_DML_REWRITE */croutreach.action set object_value = :1 where actn_id = :2 .
This update pattern is used in the production environment and is slowing the environment down as more xml content is increased. In a new release build, this update pattern against the action table described earlier, is particularly problematic.
Have some more information on the /*+ NO_XML_DML_REWRITE */ hint. It turns out, last year, updates statements would intermittently fail to correctly update silently failing. An Oracle Service Request was created. Over the span of about 5 mnths, Oracle determined a very low level Oracle kernel bug was the culprit. Oracle As a result of this SR, Oracle SUpport created BUG 11939507 <ORA-08102: index key not found during update on xmltable with a virtual column>. This bug is viewable on metalink. Oracle claims this bug has only been oberved on In the interim to 11.2.0.3, Oracle Support mentioned to use /*+ NO_XML_DML_REWRITE */; thus disabling piecewise update.
Here's preface information on this bug:

Abstract: ORA-8102: INDEX KEY NOT FOUND DURING UPDATE ON XMLTABLE WITH VIRTUAL COLUMN*** 03/30/11 12:22 pm ***
BUG TYPE CHOSEN =============== code
Component: XML Database =======================
DETAILED PROBLEM DESCRIPTION ============================
The issue happens intermittently when running a batch program with 50 concurrent sessions that involves high concurrent updates.
DIAGNOSTIC ANALYSIS =================== reproducible testcase on customer dummy data reproduced by Thomas.
WORKAROUND? =========== No
TECHNICAL IMPACT ================ Customer is experiencing this error which is critical to the application because it causes a home health care provider to possibly lose a couple hours worth of work and have to start from scratch. The condition has only accessed concurrently from about 40 threads
RELATED ISSUES (bugs, forums, RFAs) =================================== Bug 8514561 - ORA-8102 WHEN UPDATING TABLE
HOW OFTEN DOES THE ISSUE REPRODUCE AT CUSTOMER SITE? ==================================================== Intermittent
DOES THE ISSUE REPRODUCE INTERNALLY? ==================================== Intermittent
IS A TESTCASE AVAILABLE? ======================== Yes The good news is, this bug is corrupting a virtual index column.
I'll try test cases using the update pattern; 'update /*+ NO_XML_DML_REWRITE */croutreach.action set object_value = :1 where actn_id = :2 ' - substituting actual values for the bind variables and removing interfering virtual columns. Wil lcompare with and w/o the hint.
This wil address your; "Where does the new values come from? Individual variables?" - and provide sample data.
Presently, this update pattern is used 'blindly' in that when no xml relevent changes are identified, only a couple of the roughly 16 fields are updated - yet the whole document gets updated with this update pattern. When changes occur, the whole document is updated. Will work with updating 1 or 2 fields using updatexml and try the xmlexists function for the predicate.
04/25/12 Update:
odie 63,
Here's a sample xml record from the action securefile binary xml table:

UPDATE /*+ NO_XML_DML_REWRITE */ action A

where a.actn_id='888a80be-d69f-464d-b3f7-85b6209f918e';
This statment updates fine with and w/o the hint. This hint takes away the piecewise update of the xml document and relies upon the a.actn_id virtual column.
Then removed the reliance on the virtual column using the xmlexists fn.
First did an alter index 'actn_id_pk invisible' to take the virtual column out of consideration by the optimizer.

SET A.object_value = updatexml(A.object_value,'/action/@status','triggered','xmlns="http://www.xxxx.vvv/yyy/domains/actions/2010/03"')
where xmlexists('$p/action[@id="'888a80be-d69f-464d-b3f7-85b6209f918e'"]' PASSING object_value as "p");
This update runs but doesn't update any columns - with or without the hint.
Also created a basic unstructured xmlindex to remove the full table scan - which worked fine execution plan-wise.
create index action_xmlindex_ix on action (object_value) indextype is xdb.xmlindex;Per the SR on this, the /*+ NO_XML_DML_REWRITE */ disables piecewise update and is a workaround for the bug surrounding virtual column index usage when having many concurrent sessions and updates against a table with millions of xml documents. Getting rid of the virtual column in the predicate removes the need for the workaround hint.
My problem is This update runs but doesn't update any columns. Maybe am missing something or doing a syntax/semantic error ?
Any assistance much appreciated...

Can we rollback the update query using Transaction?

Can we rollback the Update query by writing the update query with in the transaction, as i am implementing different update queries, sometimes I am mistakenly updating the table without where criteria, which is messing up the table. Is there anyway where
we can write the update query within a transaction and rollback that particular update query which I am writing. I do have a backup table, but that wont be useful because we are doing lot of updates in a span of minutes. I researches about Apex Sql logs too,
but we do not have access to download such tools. So, can anyone give me a good solution for this?

Sure, if you use transaction like this
begin transaction
update 1
update 2
rollback transaction
both updates will be rollbacked.
If you want to always be sure about rows you're about to change, always first try with SELECT statement and put each individual UPDATE into separate transaction with rollback at the end, e.g.
begin transaction
select ... where some condition
update . where same condition
select ... where same condition to verify update
rollback transaction
If your last select showed correct info, change ROLLBACK into COMMIT and re-run that script again to perform the actual update.

Update query using FORALL statement

Hi ALL,
I have two tables Table: Mater_A(20 Cloumns) and Temp_A(20 Columns).
Both are almost identical. The Master_A is master table that has to be updated daily based on the temporary table Temp_A.
Everyday , i expect around 100000 records(same records with modified valus ) in Temp_A that has to be updated in Master_A. So i have to make the query as optimized as possible.
For this,I have created a cursor that has all records from table Temp_A.
Then i am using FORALL statement to update the data. But it throws exception something like that:
Error: PLS-00436: implementation restriction: cannot reference fields of BULK In-BIND table of records
Error: PLS-00382: expression is of wrong type
It states that i have to create a separate type for each column that i want to update.
I have created procedure like this:
Open C_Temp_A;
Loop
Fetch C_Temp_A Bulk Collect into v_C_Temp_A limit 5000;
Exit When C_Temp_A%NOTFOUND;
Begin
ForAll i in v_C_Temp_A.first.. v_C_Temp_A.Last
Update Master_A mst Set mst.Column2= v_C_Temp_A(i).t_Column2,
mst.Column3= v_C_Temp_A(i).t_Column3,mst.Column4= v_C_Temp_A(i).t_Column4........to all columns
where mst.Column1= v_C_Temp_A(i).t_Column1;
End;
End Loop;
Close C_Temp_A;
Please help me to solve this or suggest me any other alternative to reduce the processing time.

Why cant you use like :(Or I misread?)
SQL> select * from a;
        ID         C2
         1        100
SQL> select * from b;
        ID         C2
         1       1000
SQL> merge into b
2 using(select * from a) a
3 on (b.id = a.id)
4 when matched then
5   update
6   set b.c2 = a.c2;
1 row merged.
SQL> select * from b;
        ID         C2
         1        100

Hi Chinna,
Check like this below.
The following SQL statement selects the product name, and price for today from the "Products" table:
SELECT ProductName, Price, Now() AS PerDate
FROM Products;
Similarly,
UPDATE ProductName, Price, Now() AS PerDate
FROM Products;

How to run an update query on results from a spreadsheet

Hey there,
I am new to this kinda thing.
I received a spreadsheet that has 2 tabs, 1 is called SQL Results, and has a ton of data. 1 is called SQL Statement and has a select statement in the first cell.
I was told to run an update query using the spreadsheet, and was given this:
= CONCATENATE("Update CARDMEMBERISSUE set CURRSTATUSCD = 'ACT', DATELASTMAINT = sysdate where AGREENBR = ",A2," and MEMBERNBR = ",B2," and ISSUENBR = ",C2,";")
= CONCATENATE("Insert into CARDMEMBERISSUEHIST (AGREENBR, MEMBERNBR, ISSUENBR, EFFDATETIME, CARDSTATCD, STATREASON, DATELASTMAINT, DATESENT) values (",A2,",",B2,",",C2,",sysdate,'ACT',null,sysdate,null);"
I am not sure what to do or how to run this.
This is the what the lines in the spreadsheet look like, including column header, A1 is blank.
A B C etc
AGREE NBR MEMBERNBR ISSUE NBR CURRSTATUSCD PREFIX CARD NBR AGREETYPCD OWNER PERS NBR EXT CARD ISSUE DATE
2 12 1 44 ISS g 22 22 19/10/2011

The =concatenate bits are Excel formulae. Assuming they correctly written, they will generate a set of individual sql statements. The first concaenatewill generate a set of update statements against the CardMemberIssue table, and the seond will generate a set of insert statement to the CardMemberIssueHist table.
You should be able to just paste the generated statements into whatever tool you are using to run sql to execute them. Before you do that though, make sure that you issue:
alter session set cursor_sharing=force;before pasting anything in.

I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work

Hi,
I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work
(fault number -2147217900)
I want to search for a value in a ms access table , if it exist i want to update it, if not i want to insert a new row.
Working with LabView 7.1, database con. toolset.
Who can HELP?
Thanks a lot
Marco

Hello,
I think that If exist is not a standar SQL command (I know it exists I think in Oracle and SQL server), MS access doesn't support it, so I think the best way to do it is first make a Select and then either an Update or an insert, sorry...

I want single update query without use the function.

I want to update sells_table selling_code field with max date product_code from product table.
In product table there is multiple product_code date wise.
I have been done it with below quey with the use of function but can we do it in only one update query
without use the function.
UPDATE sells_table
SET selling_code = MAXDATEPRODUCT(ctd_vpk_product_code)
WHERE NVL(update_product_flag,0) = 0 ;
CREATE OR REPLACE FUNCTION HVL.maxdateproduct (p_product IN VARCHAR2) RETURN NUMBER
IS
max_date_product VARCHAR2 (100);
BEGIN
BEGIN
SELECT NVL (TRIM (product_code), 0)
INTO max_date_product
FROM (SELECT product_code, xref_end_dt
FROM product
WHERE TO_NUMBER (p_product) = pr.item_id
ORDER BY xref_end_dt DESC)
WHERE ROWNUM = 1; -- It will return only one row - max date product code
EXCEPTION
WHEN OTHERS
THEN
RETURN 0;
END;
RETURN max_date_product;
END maxdateproduct;
Thanks in Advance.

Hi,
Something like this.
update setlls_table st
        set selling_code =(select nvl(trim(product_code)) from
                              (select product_code
                                      , rank() over (partition by item_id order by xref_end_dt DESC) rn
                                   from product
                               ) pr
                               where rn =1
                                     and pr.item_id = st.ctd_vpk_product_code
                           ) where NVL(update_product_flag,0) = 0 ;As such not tested due to lack of input sample.

ERROR: Updatable SQL Query already exists on page 20.

Hello,
I created a tabular form, then added a where clause and started getting the following error:
Error in mru internal routine: ORA-20001: no data found in tabular form
So I deleted all components of the tabular form (region, buttons, branches and process) and started building it again from scratch. This is a strategy that has worked for me a number of times in HTML DB. Unfortunately now I get the following error when trying to build a new tabular form:
Updatable SQL Query already exists on page 20.You can only add one updatable SQL query per page. Select a different page.
What is the logic that throws this error. I'm 99% convinced I've cleared the page of any updatable SQL, is there something on the application level I should also clear out?
Thanks!

Ignore this, problem solved. It seems I do have SQL reports that are marked as updatable even though they are just plain reports.
Sorry.

Using nested IIF expressions in an update query - is it possible?

Hi everyone,
I've been tasked by my manager to build a database which replicates a large, complicated Excel spreadsheet that consumes too much of our team's time and system resources. I've just about got most of it, but there is one particular required field that, in
Excel, requires multi-layered nested If/Then formulae. I have to ask if building something similar in Access is possible. Here is the problem and the logic:
Let us assume two established fields, Field 1 and Field 2; and then one field to be created via Update query, Field 3.
Let us further assume that in Fields 1 and 2, there are three specific alphanumeric sequences occurring (“X1A”, “X1”, and “Z1”) that need to be identified and then called out as either “S1” or “U1” in field 3.
If an Update Query were to be written to populate Field 3 with either “S1” or “U1” depending on one of the three alphanumeric sequences appearing in either Field 1 or Field 2, could it be written as the following expression, using the IIF and OR operators?
And if so, is the syntax of the following expression correct?
IIf([FIELD 1]="* X1A", "U1", OR IIf([FIELD 2]="* X1", "U1", OR IIf([FIELD 2]="* Z1", "U1", OR IIf([FIELD 1]="* X1", "U1", OR IIf([FIELD 1]="* Z1", "U1", "S1")))))
Any help, critiques, or guidance would be appreciated.

IMHO, a main consideration when "migrating" from Excel to Access is that a relational database is fundamentally different from a spreadsheet (although there can be much overlap). In Excel, calculated values are "live" (unless you paste the values only
into some other cells). To replicate this "live" quality in Access, you can use a query with a calculation to display (not create or update) Field 3 in your case; Field 3 really wouldn't be a field, just a representation (query, form, report) or snapshot
(export, print). One reason for this is to avoid conflicts and redundancy. In other words, if Field 3 is based solely on Fields 1 & 2 and some rule, then usually there is no need to waste disk space to store Field 3 and you don't risk Field
3 being wrong as in the case when the rule changes.
So here are a couple of options.
1) Create view only query to display Field 3. In query design view, enter the following where you would normally select a field:
[FIELD 3]: IIf([FIELD 1]="* X1A", "U1", IIf([FIELD 2]="* X1", "U1", IIf([FIELD 2]="* Z1", "U1", IIf([FIELD 1]="* X1", "U1", IIf([FIELD 1]="* Z1", "U1", "S1")))))
I assume you literally mean the asterisk character and are not trying to invoke a wildcard for the LIKE operator.
There are other ways of doing this (e.g. with the LIKE operator or multiple queries and UNION), but I leave that up to you to explore.
2) Actually update the value of FIELD 3 in a table. Create two update queries and use your rules as conditions (i.e. the criteria in the bottom of query design).
a) Update query 1 (run first): set [FIELD 3] = "U1" where [FIELD 1] = "* X1A" OR [FIELD 1] = "* X1" OR [FIELD 1] = "* Z1" OR [FIELD 2] = "* X1" OR [FIELD 2] = "* Z1"
b) Update query 2 (run after): set [FIELD 3] = "S1" where [FIELD 3] is null
Again, there are other ways of doing this such as setting the default value of [FIELD 3] in the table to "S1" and just running update query 1.
Good luck.

key =system.user.
So when i connect to the wlst command console in MW_HOME/oracle_common/common/bin/wlst.sh
and connect to the server and execute the command
updateCred(map='oracle.bi.system', key='system.user',user='BISystemUser',password='welcome1') i get the error already in the Domain runtime tree.
I tried
import jpsWlstCmd
jpsWlstCmd.updateCred(map='oracle.bi.system', key='system.user',user='BISystemUser',password='welcome1') but still i get the same error.
Can anyone help me modifying the credentials using a script.

After extending my domain with JRF and JRF WebService Asynchronous services, I was able to execute "createCred" and "listCred" and so on.
