How to update Query PLD

Hi all,
I have prepare a query and generated a PLD for it.
Now I required some changes in Query (say I have selected 2 more fields) and when I executed the PLD, it shows old query only.
Is there any way to update the PLD according to new query ?
Thanks in advance,
Samir Gandhi

The query code is stored together with the PLD. There is no way to change it.
But you can copy the design of your old PLD to a new one. So you should:
1. Create report for the modified query
2. From its PLD delete every field definition (after select all . . .)
3. Open the old PLD, copy all field definition from it (after display hidden fields and salact all)
4. Past the field definition to the new PLD.
5. Make the necessary modifications.

How to Update query

Can I write a single update query to update Data of one table to another
<Table1>
ID number
fname varchar2(10)
lname varchar2(10)
<Table2>
ID number
fname2 varchar2(10)
lname2 varchar2(10)
Both the table contains data, and I want to write a single query to update fname and lname from <Table2> to <Table1>
Note: ID contains common value

How to update/query informix table for every update/query on Oracle table

We have a system that can talk to only Oracle.
Here, we have a certain program that updates an Oracle table thru a View of the Table. For every database operation on Oracle table View, we want to update a corresponding table in Informix database.
Similarly for every query on the View of oracle table we want to query informix database and fetch the records from there.
We want to use Oracle as a medium to access Informix.
Can some one help me on how to do this ?
Thanks

You can use the Transparent Gateway for Informix to access Informix from an Oracle environment. The gateway makes the Informix database look like a remote Oracle database.
You can take a look at the gateways page on OTN for more information on this. http://otn.oracle.com/products/gateways/content.html
Look at the Certification matrix to ensure that you are using a certified configuration.

How to update query at runtime

I have one input page in which i display only some fields from a table (some are hide through to model -> attributes --> properties). i have a mandatory field in one of hidden fields and i need to set some default value to that field after user clicks on Commit button. How to do that. Can some body helps me.

Hi,
Thank you Duncan and Scott. I set it through entity object properties and it is working fine.
One more help,
I want to display two table fields in one insert form (JSP) and after the values are entered it has to be insert in to two tables. Do you have any document or help manual on that.
Thanks,

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:

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...

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.

How to update this query and avoid performance issue?

Hi, guys:
I wonder how to update the following query to make it weekend day aware. My boss want the query to consider business days only. Below is just a portion of the query:
select count(distinct cmv.invoicekey ) total ,'3' as type, 'VALID CALL DATE' as Category
FROM cbwp_mv2 cmv
where cmv.colresponse=1
And Trunc(cmv.Invdate) Between (Trunc(Sysdate)-1)-39 And (Trunc(Sysdate)-1)-37
And Trunc(cmv.Whendate) Between cmv.Invdate+37 And cmv.Invdate+39the CBWP_MV2 is a materialized view to tune query. This query is written for a data warehouse application, the CBWP_MV2 will be updated every day evening. My boss wants the condition in the query to consider only business days, for example, if (Trunc(Sysdate)-1)-39 falls in weekend, I need to move the range begins from next coming business day, if (Trunc(Sysdate)-1)-37 falls in weekend, I need to move the range ends from next coming business day. but I should always keep the range within 3 business days. If there is overlap on weekend, always push to later business days.
Question: how to implement it and avoid performance issue? I am afraid that if I use a function, it greatly reduce the performance. This view already contains more than 100K rows.
thank you in advance!
Sam

You are already using a function, since you're using TRUNC on invdate and whendate.
If you have indexes on those columns, then they will not be used because of the TRUNC.
Consider omitting the TRUNC or testing with Function Based Indexes.
Regarding business days:
If you search this forum, you'll find lots of examples.
Here's another 'golden oldie': http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:185012348071
Regarding performance:
Steps to take are explained from the links you find here: {message:id=9360003}

How to execute a update query when the particular date changes

hi all,
i am using date base 11.1.0.6.0,
i am trying a small update query it should fire when particular date changes in year.
i think for trigger but i didn't get how to execute it.
Regards,
Pavan

Hi, Pavan,
Use dbms_scheduler to run a procedure at a given time (or at repeatedly, at given times).
A trigger is good for re-acting to certain actions in the database, someone INSERTing a row in a given table, for example. Nothing will necessarily be happening when you want your procedure to run, so a trigger is not good in this case.

How can update two rows in one query?

How can update two rows in one query?
Edited by: OracleM on May 4, 2009 12:16 AM

What do you mean with "two rows"? May be two columns??
If the where clause of UPDATE query matches two rows, then it will update two rows. If you want to update two columns, then add column names to your query
UPDATE your_table SET col1=value1, col2=value2 WHERE your_where_clause- - - - - - - - - - - - - - - - - - - - -

How to update multiple rows in one query using php

i am new to this can any one help me how to update multiple rows at a time i am doing an school attendance page

Often the situation is such that you have multiple courses across a range of dates.So students may take more than one course, and you need to track attendance for each course date. The following graphic demonstrates this:
In such a situation, you need four database tables as follows:
students (student_id, student_name, etc.)
courses (course_id, course_name, etc.)
students_courses (student_id, course_id)
attendance (student_id, course_id, dater)
A fifth table may also be needed to define the dates of courses, but you may also be able to build this array programmatically by using PHP's robust date functions, which can give you, for instance, all the Tuesdays and Thursdays between a start date and end date.
The students_courses table simply keeps track of which students are taking which courses, so it has just two columns for the primary keys of both of the main tables. The attendance table is similar, but it also includes a date field. The following view of the attendance table demonstrates this:
So if David's solution does cover your needs, consider yourself lucky, because this could quickly grow from a beginner-appropriate project to a moderately advanced one.

How to use xs:date() in an update query?

I cannot test xs:date attributes in an "update" query. In a "select" query, all work fine.
This is the sample schema:
<?xml version="1.0" encoding="utf-8"?>

<xs:schema xmlns:tns="http://OracleTest" xmlns:xdb="http://xmlns.oracle.com/xdb" elementFormDefault="qualified" targetNamespace="http://OracleTest" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="MyComplexType">
<xs:sequence>
<xs:element minOccurs="0" name="FirstChild">
<xs:complexType>
<xs:attribute name="A" type="xs:string" />
<xs:attribute name="B" type="xs:string" />
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="ID" type="xs:string" />
<xs:attribute name="DateAttr" type="xs:date" />
</xs:complexType>
<xs:element xdb:defaultTable="MyElement" name="MyElement" type="tns:MyComplexType" />
</xs:schema>
This is a sample XML document:
<?xml version="1.0" encoding="utf-8"?>

<tns:MyElement ID="ID1" xmlns:tns="http://OracleTest" DateAttr="2008-03-14" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://OracleTest http://OracleTest.xsd">
<tns:FirstChild A="a" B="b" />
</tns:MyElement>
If I check the DateAttr attribute in a xquery, it works fine:
select xmlquery('declare default element namespace "http://OracleTest"; collection("/Testing")/MyElement[@DateAttr=xs:date(''2008-03-14'')]' returning content).getclobval() from dual
If I execute an update, like this:
UPDATE RESOURCE_VIEW SET RES = deleteXML(RES, '/oraxdbr:Resource/oraxdbr:Contents/Testing/MyElement[@DateAttr=xs:date(''2008-03-14'')]','xmlns:oraxdbr="http://xmlns.oracle.com/xdb/XDBResource.xsd" xmlns="http://OracleTest"')
WHERE equals_path(RES, '/Testing/test1.xml') = 1
I get the error:
SQL Error: ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00607: Invalid reference: 'date'.
31011. 00000 - "XML parsing failed"
Where is the problem?
Thank you!
Mirko

Hi,
Correct me if I'm wrong, but didn't xs:date() came with xpath 2.0?
deleteXML supports xpath 1.0 .
XMLQuery supports xpath 2.0.
That's why the error "Invalid reference: 'date'".
what function supports which version read Re: Which version of XPathAnts

How to update id in Table1 from Table2 on joining condition Table1.dept=Table2.dept

No it's not running, giving some error.That is because SQL server construct is different than that of Oracle.
Try with

However, due the repeated department values will not give you the desired output.
