Many to One in Triggers
Hello,
I am writing a Trigger that needs to perform the following , if there is any change in any of columns of Table A I need to propagate the same to Table B . By changes I mean insert(s)/update(s) or delete(s).
if table A has one row representing say Column1 which is an integer then it is a clear & simple copy of values .
However if table A has multiple rows having the same Column1 I need to choose the minimum of the values in Column1 & whichever column has the minimum value need to put it in Table B . Let us assume Column1 is of Integer type .
Would appreciate any suggestions regarding teh same
With Regards
The Second table basically resides in another schema , the whole idea is to make sure the second table has the same data as the first one , I don't want to get rid of the first table as it is still being used by old applications but I need a new table for the newer app's that don't need as much details as the older app's but need a representative row (atleast one column for Column1 values) .

Crystal Report Many to One Query Config error when using DataSet.ReadXML me
When I build a dataset with this method numerous relations are automatically created. I then map these fields onto crystal reports with ADO.net data connection. However when I run the report the following error occurs:
CrystalDecisions.CrystalReports.Engine.InternalException: Cannot determine the queries necessary to get data for this report.Details:
This query cannot be performed. The link order requires many to one query configuration, which is not supported. Please rearrange the links.
If I remove the links (relations) i get duplicate data on the report. Is there any way to resolve this or a patch for the error?Hello, Mervin;
Since you are using ADO.NET dataset, is it possible to get all of the fields you need in one SQL Query outside of Crystal Reports?
If that is possible, you can use that dataset to create an XML or XSD file to use as the structure for your report.
VB
'Using the full path to the .xml file, include the schema
dataSet.WriteXml("C:\temp\test.xml", XmlWriteMode.WriteSchema)
or
dataSet.WriteXmlSchema("c:\temp\testXML.xsd")
Now create a new report with the ADO.NET(XML) connection and point to either the XML or XSD you created. XML is useful because you can view data in the report designer for final formatting of the report.
Now there is only one datasource and no linking is required in Crystal Reports. That should resolve the one to many issue.
Another useful tool is to group on the many and place all the fields normally in the detail section into that group header. Suppress the Detail and Group footer sections. The Group Header will now look like a Detail section and each distinct value will only appear once. You can group on one field or a combination (using a formula field) to get the results you need. Test this to be sure you do not miss anything you want to see.

Does anyone know how many devices one can have on one apple ID?
Does anyone know how many devices one can have on one apple ID?
The names are for your benefit. The devices are identified by serial number in iTunes. iTunes knows which device is which no matter what you name the devices. It works the same way with iCloud. You can name all three devices Fred - and iTunes can tell them apart - but like I said, you want to give them different names for your benefit.

Hi Experts,
I am currently facing issue with many to one mapping . I have a source schema called revenue having Profit and Profit GST which is looping multiple times. I need to copy the name,value and GST value for each type into the destination schema.
i am using Looping funtiod to create item profit records and than copying name and value from source to destination but the problem statement is that i am unable to map the GST value
Thanks
Abhishekcould you post the schema definition please
well why i am asking is, in General matching the records will be based on common node values in corresponding records.
Assume you have 2 records of Profit and 2 records of ProfitGST in the source message like below, you cannot match the records unless you have some value common in both the records. i mean there should be some common node or attribute value that exits in
both records.
assume the following sample with 2 records each
<ns0:Revenue xmlns:ns0="http://TestSample">
<ns0:profit availabilityIncentivePayment="342" increasedCapacityCharge ="121" increasedCapacaityPayment="231" />
<ns0:profit availabilityIncentivePayment="100" increasedCapacityCharge ="110" increasedCapacaityPayment="120" />
<ns0:profitGST availabilityIncentivePayment="55" increasedCapacityCharge ="21" increasedCapacaityPayment="23"/>
<ns0:profitGST availabilityIncentivePayment="150" increasedCapacityCharge ="160" increasedCapacaityPayment="170"/>
</ns0:Revenue>
if you observe the above sample instance, it does have 2 records each, but Profit record's nodes values
are no where common with ProftGST record's node values.
And for every Profit record, you want to pick corresponding GST value from ProfitGST record. However, since you don't have atleast one common node/attribute value here, you will not find a way to relate corresponding records. Means while mapping the first
record of Profit, it cannot decide which record's nodes values in the ProftGST should pick to match as there are 2 records of ProfitGSt and with no relation with Profit Records.
if the requirement is such that the records should be matched by the order(index) irrespective
or the values in them, then that can be achieved easily with postion() function in the for loop. just try to use code some thing like below sample xslt script like below, apply the proper name spaces and put full names as applicable in your scirpt, mould
it as per your need
<ns0:Root>
<xsl:for-each select="Profit">
<Profit>
<xsl:if test="@availabilityIncentivePayment">
<name>
name>availabilityIncentivePayment</name>
</name>
</xsl:if>
<xsl:if test="@increasedCapacityCharge">
<Value>
<xsl:value-of select="@increasedCapacityCharge" />
</Value>
</xsl:if>
<xsl:if test="../profitGST/@availabilityIncentivePayment">
<ProfitGSt>
<xsl:value-of select="../profitGST/@availabilityIncentivePayment[position()]" />
</ProfitGSt>
</xsl:if>
</Profit>
</xsl:for-each>
</ns0:Root>

SSAS - Many to Many Relationship Grain Filters Out Data (Many to One)
I have a simple Many to One example: One Fact Table record has many Dimensional Items. The Example I'm using is One FactEvent record can have multiple EventMembers. These members are always unique so the relationship is really many to one (vs.
many to many). The grain of the Fact is one row for every event. Not all events have members, but I have stubbed those with -1
I tried using a Referenced dimensional relationship, but it threw my total counts off. I decided to make it more complicated by using a
Many to Many relationship, but I had issues once I started slicing the data.
The following are my two very simple tables:
FactEvents:
EventMemberID MemberKey EventMemberKey MemberName MemberGender
1 1 -1 None N
2 2 E2 Tyler M
3 3 E2 John M
4 4 E2 Sue F
5 5 E5 Tim M
6 6 E5 Jane F
7 7 E12 Ashley F
8 8 E12 Jessica F
9 9 E12 Kristy F
10 10 E17 Mike M
11 11 E17 Josh M
12 12 E18 Warren M
13 13 E18 Eric M
Here is the bridge Table:
EventID EventBK EventName EventMemberKey EventCount
1 E1 Hockey Game -1 1
2 E2 Soccer Game E2 1
3 E3 Baseball Game -1 1
4 E4 Concert -1 1
5 E5 Food Festival E5 1
6 E6 Movie Night -1 1
7 E7 Data Group Event -1 1
8 E8 City Tour -1 1
9 E9 Ski Trip -1 1
10 E10 Camping Trip -1 1
11 E11 Hiking Trip -1 1
12 E12 Community Cleanup E12 1
13 E13 Block Party -1 1
14 E14 Toastmasters -1 1
15 E15 Train Spotting -1 1
16 E16 Plane Spotting -1 1
17 E17 Fishing Trip E17 1
18 E18 Hunting Trip E18 1
19 E19 Street Hockey -1 1
20 E20 Bonspiel -1 1
You can see many events have no members and some events have multiple members. There is not separate members Dim, just the bridge table. I tried to build view that would work as bridge tables, but it started to feel like overkill.
Here is the SSAS structure:
Cube:
I tried creating a bridge Dim and Measure Group that can be used to join FactEvents with DimMemberEvent:
When I query the database tables directly, I can get the structure I'm looking for:
Gender Count
F 5
M 7
N 15
This represents that although there are 20 events, there were 5 Female and 7 Male participants and 15 events with No participants. When looking at the cube in excel I get:
Gender Count
F 3
M 4
N 15
Grand Total 20
The grand total is correct, however, it looks like it is grouping the events, so if there are multiple Female members at a particular event, they get rolled up. You can see this better if I pull in member name:
It includes all the names with count 1 ie. 5 Females with count 1, but the gender subtotal is 3 (as it is grouping the gender dimension)
The detail member counts are good, but the rolled up M and F counts are stripping out duplicates. Is there a way to model this in SSAS to preserve the detail member counts when the member dimension is used? Is a many to many the best solution?
This is all using SQL Server 2012 Multi-Dimensional Model. Thanks.Ok, for starters, if it's a one to many relationship, don't set it up as a many to many! Avoid many to many relationships and really anything other than "regular" relationships.
Second, the tables you pasted the data for aren't the tables you are describing them as, based on the dsv screenshot you included. If your post is confusing to the people who are wanting to help you, they will quickly move on.
It seems that you are not clear on how to construct a star schema. I will lay one out for you and hopefully this can help you on your journey.
fact_member_event:
event_id
member_id
member_event_count
dim_member:
member_id
member_key
member_name
member_gender
dim_event:
event_id
event_name
fact_event:
event_id
event_count
Or alternately, you could drop the fact_event fact table and have a calculated member that uses dimEvent.event.event.allmembers.count. It's a little bit of a weird situation that I would want to play with, but I would start with the above.
Also if you post back and show query results, you should make it clear what columns you are displaying. I see "count" in your query above, but nowhere in the star schema do I see "member count"
as a field.. I guess that's event count?
Hope this helps,

XQuery many to one in an XML document ??
I have XMLType tables with xml documents that have data like the sample below.
There are one to many InvoiceLineRet to one InvoiceRet, how do I return this data in an XQuery?
I have tried many iterations but cannot get data to return correctly. It is somewhat like a many to one table relation where in the query the one side would repeat across the many lines, but it does not work that way with XQuery.
Any and all suggestions will be appreciated.
Thanks,
Mike

I i want to run many-to-one replication scenario
Hi,
i want to run many-to-one replication scenario and for that i have created two tables and inserted values on source db and one table on target db in which i want consolidated data from those two tables. Below are the table details,
Source DB,
CREATE TABLE GGS.CLIENT_INFO
( CLIENT_ID varchar2(10) not null,
CLIENT_NAME varchar2(50) not null,
CLIENT_ADD varchar2(50),
CONSTRAINT CLIENTID_PK PRIMARY KEY (CLIENT_ID)
CREATE TABLE GGS.ACCOUNT_INFO
( ACCOUNT_NO varchar2(15) not null,
BANK_NAME varchar2(50) not null,
CLIENT_ID varchar2(10) not null,
CONSTRAINT ACCTNO_PK PRIMARY KEY (ACCOUNT_NO)
alter table GGS.ACCOUNT_INFO add CONSTRAINT FK_CLIENTINFO FOREIGN KEY (CLIENT_ID) REFERENCES GGS.CLIENT_INFO(CLIENT_ID);
Target DB,
CREATE TABLE GGS1.CLIENT_ACCOUNT_INFO
( CLIENT_ID varchar2(10) not null,
ACCOUNT_NO varchar2(15) not null,
CLIENT_NAME varchar2(50) not null,
CLIENT_ADD varchar2(50),
BANK_NAME varchar2(50) not null,
CONSTRAINT CLIENT_ACCOUNT_PK PRIMARY KEY (CLIENT_ID, ACCOUNT_NO)
when i start replicat process, it is giving below error,
*"Oracle GoldenGate Delivery for Oracle, CLACTDEL.prm: OCI Error ORA-01400: cannot insert NULL into ("GGS1"."CLIENT_ACCOUNT_INFO"."CLIENT_NAME") (status = 1400), SQL <INSERT INTO "GGS1"."CLIENT_ACCOUNT_INFO" ("CLIENT_ID","ACCOUNT_NO") VALUES (:a0,:a1)>."*
Note: i am inserting two source tables data in one table which at target side using OGG capture-replicate process.
Please help to resolve above error.
Regards,
ShitalFor one, do not use the GoldenGate database user as your source and target schema owner. Why? What happens in a bidirectional setup? To prevent ping-ponging of data, operations performed by the replicat user should be ignored. That's what keeps the applied update on a target being re-applied on the original source, and then being captured and sent to the target, etc.
Without knowing your setup, what did you do for ADD TRANDATA and supplemental logging at the database level (only needed for the source)? What did you do for initial load and synchronization? What are your parameter files?
The error shown so far - cannot insert null - applies everywhere in Oracle whenever you try to insert a record with a null value in a column where a NOT NULL constraint is present. You can see that for yourself in a SQL*Plus session and trying the insert. You are inserting two column values, when your own table definition shows you would need at least 4 values (to account for all of the not null constraints). -
Isn't the five computer limit for home sharing restrictive given the many devices one household may have?
It is only restrictive if you have more than 5 computers.
Otherwise it is not restrictive at all.
devices do not count, only computers.
You have more than 5 computers on the same home network. -
I'm trying to implement a many-to-one relationship similar to the one, for example, between an OrderLineItem and a Product.
I managed to create the beans and define the relationship using deploytool.
What I'm trying to understand is how can I prevent a Product instance from being deleted when it is involved in the relationship described above?
Currently, under Sun's reference implementation server, I am allowed to delete a Product even if there are OrderLineItems that reference it.
There is one line printed out in the window running j2ee -verbose:
com.sun.ejb.containers.EntityContainer$EJBTxKey
The record in the Product table is deleted nonetheless.
Another weird thing is that the server does not allow me to deploy two beans involved in a many-to-one relationships with the Product bean if they are using the same CMR field name. What I get is a compilation error at the deployment time.
I'd appreciate any input.They way I handle this is to hide the creation/manipulation/deletion of the bean behind a manager - for example a singleton session bean. I NEVER allow the direct creation/deletion of entity beans except through manager classes. This is quite a common J2EE pattern, whose name escapes me at the moment.
Your manager would have a method like delete(int productId), which would delete the matching Product entity bean, and would then search the OrderLineItem beans for the matching Product primary key. -

"Illegal many to one link" error
Hi,<br /><br />I'm using JRC to integrate Crystal reports into a web application. When I'm trying to change the database connection info at runtime, the 'Illegal many to one link' error is shown. I've tried to search for description of that error, but found no solution. The preview in Report Designer works fine.<br />Could you suggest anything?<br />I'm using Crystal Reports XI (Developer)<br /><br />Thanks.<br />
I am also getting this error using a jdbc connection to an Oracle 9i database. I am creating reports against a test database which has the same schema as the production database.  Due to configuration issues, I do not have access to our production database from my Crystal Reports Design envirionment so I need this code to work to retrieve produciton data when running through the JRC on our production system.
Any help would be appreciated. -

similer with address. So tell me how i will do in oracle warehouse builder 10G.
exp: many to one
the address is stored in 4 attributes in source and i want to store in one field or 2 fields in oracle
warehouse builder. tell me about it.
i shall be thankful to you for this kindHi
Use expressions!
Select an expression and connect the sorce fiedl to it. Create 3 output filed and define the expressions for them:
- substr( source_field, 1, instr(source_field, ' '))
- substr( source_field, instr(source_field, ' '), instr(source_field, ' ', 2))
- substr( source_field, instr(source_field, ' ', 2)).
For many to one concatenate them in an expression. Create an expression, connect the source fileds, create an output filed and in the expression use this:
- field1 || ' ' || field2 || ' ' || field3 || ' ' || field4.

Many to one relationships strange behavior
I have a problem with two many to one relationships.
The problem appears from the dirty mechanism of cmr/cmp fields.
When I have two “many-to-one” relationships ex:
A n..1 B
A n..1 C
Navigability: B -> A
A <-> C
When I put in ejb-jar.xml the B to A relation first, the bugs appear. The dirty mechanism work chaotic. The problem is in the generated code for the PersistenceManager and Wrapper of the A bean.
In the Wrapper the only fields with dirty mecansim are the real fields from bean which are navigable. In the PersistenceManager class are the same fields like in the BeanWrapper plus the fake fields for relationship. But the fake fields are intercalated with real fields and the dirty flag values are not the same with the dirty flags from BeanWrapper. Result: chaotic updates.
Solution(workaround – not elegant): put first the relation which has navigability from A to C and second A to B.They way I handle this is to hide the creation/manipulation/deletion of the bean behind a manager - for example a singleton session bean. I NEVER allow the direct creation/deletion of entity beans except through manager classes. This is quite a common J2EE pattern, whose name escapes me at the moment.
Your manager would have a method like delete(int productId), which would delete the matching Product entity bean, and would then search the OrderLineItem beans for the matching Product primary key. -
I have had TOPLINK-28018 error afte I had added one-to-many or many-to-one
Hello.
I am using TopLink and Spring. I have the followng persistence.xml:

All my classes are inherited from StateOwner.class and only the RTerritory class has "one-to-many" and "many-to-one" relationships. When I add rterritory.xml to persistence.xml I have the following error (before all works fine):
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).

If I make "parentTerritory" and "children" transient - all works well. Above workes also (comment out and without transient) on OpenJpa.
What do I do wrong if I use TopLink?
This is part of my applicationContext.xml
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation"
value="/META-INF/persistence.xml"/>
<property name="jpaVendorAdapter">

</property>
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
</property>
</bean
Thanks a lot.Hello.
Thanks a lot for answer.
When I comment out and remove transient I obtain the following exception:

This is my rterritory.xml now:

I can't understand What do I do wrong when I include "one-to-many" and "many-to-one" mapping? I want to note it (above mapping) works rightly if I use OpenJpa and one works rightly with TopLink if I remove one-to-many and many-to-one and do them transient.
Thanks a lot.

I'm using DataServices to manage hiberate objects. I have a simple many-to-one relationship between Account and Transaction (an account has many transactions). I have two DataGrids in my application, one display accounts and their balances(which are derived from the trasactions, there is no balance field) the other displays transactions. When I edit the accounts, the changes are propogated to the child transactions. However, when I edit the transactions, the changes are not propagated to the accounts automatically. If I edit the account or resort the columns it will update the balance. My data-management-config.xml is below. My question is, is there a way to make this work or is this not working by design? I want my Account objects to automatically get the new Transactions associated with them so the balance will update correctly.

on now.
Regarding the first question: In this case I am just modifying an attribute,
the relationship between them remains the same.
I verified that adding a transaction does not update the size of the
transaction collection the account has if I add the new transaction to the
transactions collection. However, if I add the transaction to the
appropriate accounts list of transactions it does update the collection
(i.e. there is one more element) but it does not update the balance. I have
since changed my balance to a property that is calculated by a query server
side. I noticed that even if I change a property on the account, it will
not update the balance unless I call fill again.
So I have two questions: 1) is there a way to make the account realize it
has transactions added to it without adding them directly to the account's
transaction collection? 2) Is there a way to force the account object to
refresh the balance (i.e. re-run the query to generate it?). I realize I
can call fill() again client side and easily fix this, but I would like to
do this in a way that causes all clients to have their account balances
refreshed when the should i.e. I want the server to automatically push the
new balance property. If it matters I'm using HibernateAssembler. Could I
extend that to achieve this?
