Create record with manual guid / primary key
Hi All,
Is this possible to create record in some entity in dynamics crm with set manual id / primary key / guid?
like this:
Entity entity = new Entity("new_test");
entity.Attributes["new_testid"] = new Guid("688008C8-F95D-4158-BAB2-A3F695D7BEEF");
entity.Attributes["trs_name"] = "AAAAA";
organizationservice.Create(entity);
is there any impact if I do that?
please advise.
thanks
I have try it my development server, and it's work
actually, this question for my requirement that need do integrate between another system to CRM, which the another system has guid as their PK (primary key) and they push their record to CRM using CRM web service and put their PK / guid value as Id in CRM's
entity that they pushed.
but, I have consult with microsoft support with this technique and I don't want get trouble in later time, and they said this is not recommended from microsoft, even it work as I said before.
thanks.

JDeveloper 10g Creating a new record with trigger sequence primary key
Hi there, I'm sorry to post this incredibly simple question and I'm sure that someone must have answered this on this forum before but the searching of this site is incredible slow and painful and after 30 mins I can't find help.
I am using a struts Data Action to create a new record in the database and then being forwarded to an edit page where I can enter the new details. Then when the details are entered I am clicking an update button and returning to a browse screen where I can either commit the change to the database or rollback. Sounds pretty simple but I am really struggling with trying to get the trigger of the number sequence to work properly.
Ideally I would like to click the create new record button and then the primary key/triggered sequence number is already displayed on the empty form...
... but if this is too tricky or not possible then I would like the user to either not enter any value in the key field (which currently causes error - JBO-27014: Attribute PoNo in PO_SYS_MODULE.PoSystemView1 is required) OR the user enters a number and the trigger overwrites this number with the next in the sequence.
I can enter a new record if I look in the manager console and see the next number in the sequence and then create the record using this number and then click commit twice, as the first time I get the error: JBO-25019: Entity row of key oracle.jbo.Key[154 ] not found in PoSystem. Or if I enter a value 5 times greater than the next in the sequence I have to click the commit button 5 extra times to get the sequence to match the input.
I hope that this lengthy explanation fills you in on my problem, there must be a simple solution to this and I will be VERY grateful to anyone who can help me.
Many thanks
Ben Sayers (clearly a newbie)Hi,
ADF Business Components handles this for you - unless yo prefer doing this manually. In the Entity Object, set the PK attribute's type to DBSequence. Then create a database sequence and use a database trigger to add the sequence value on insert

Manually Entering Primary Key.
Hi,
I am in the very early stages of looking at creating Apex Forms/Reports to replace our existing systems on Oracle Forms.
In the existing database, there are huge numbers of tables that use manually enterable primary keys when creating the record.
These primary keys can be very simple, such as just a 6 character code field or 20 character reference field (made up of several different user enterable fields concatenated together) to multiple composiite primary keys, where there could be several levels of master/detail records.
I have looked in the forums for information on this but am struggling to find a way of being able to create records where the primary key can be typed in manually when inserting records and then getting the reports/forms to work. I do not need to update the primary key, just allow it to be entered.
It would just not be practical to create new sequences as primary keys for all our tables, just to get Apex to work how it wants - wouldn't this mean dropping the existig PK and creating a new one, then populating all records with the new sequence?
I need to be able to use tabular forms for multi row record inserts where the user can enter (but not modify) the PK - using a report/form to do this seems too long winded. I will also need to be able to do this in a form only, for inserting singular records.
Any help would be appreciated.
Regards,
Carlyou should set in your entity object the attribute as DBSequence and then create a before insert trigger in the db table to get the pk from a sequence or so, something like:
CREATE OR REPLACE TRIGGER trigger_name
BEFORE INSERT
ON table_name
FOR EACH ROW
begin
select seq_name.nextval into :new.pk_id from dual;
end; -
Updation of table records having 5-6 primary key columns.
I have a table structure having 12 primary composite keys.I have created report + form on this table.My requirement is to update the table by using form items fields.I am taking help of url option on report attribute page of application to fetch data on form page when we click on edit link of report page.Now i am having two problems which are as follows:-
(i)I am unable to update data as requirement is to update 5 to 6 primary fields along with other non primary keys.I tried to create Pl/SQL process which will run update query but this process is not updating values.Is there any way that i could fetch data direct from database table in query rather then taking item values.Is there any other workaround?
(ii)One of the primary key column contains records which have ' , ' in them .For ex:- cluth,bearing.So when i get navigated to edit page i am only getting text displayed as clutch i.e. text before ',' is getting displayed in text field while comma and the text after this is not getting displayed in text field of form page.
Any solutions will be very helpful.
Thanks
AbhiHello Abhi,
>> I am unable to update data as requirement is to update 5 to 6 primary fields along with other non primary keys
APEX wizards support a composite PK with up to 2 segments only. For every other scenario, you’ll have to manually create your DML code.
If you have control over your data model, I would listen very carefully to Andre advices. Using a single segment PK is the best practice way. If you can’t add PK to your table, it seems that you’ll have to write your own DML code. The Object Browser option of creating a Package with methods on database table(s) can be a great help.
>> … I am taking help of url option … One of the primary key column contains records which have ' , ' in them …
Using the f?p notation, to pass a comma in an item value, you should enclose the characters with backslashes. For example,
\cluth,bearing\In your case, it should be the item/column notation.

Database Adapter Merge with char/varchar primary key
Hi guys,
It seems as though merge statements in BPEL database adapters do not work if the primary key of the table contains a char/varchar. This is in Jdeveloper 10.1.3.4.0
If I create the table below:
create table test_merge (
id number primary key,
text varchar2(255)
);Then the merge operation will update and insert as expected. However, if I create the same table but with id as a char/varchar, then the merge statement will never update.
It seems like it never finds a record with the same id (if it is a char/varchar), and always attempts to insert, which results in unique key constraint errors for the primary key column.
Has anyone else encountered this issue and found a way to get the merge statement to work correctly? I can obviously perform the select myself, and then conditionally update/insert, but I would prefer the merge to work as expected.
ThanksAfter investigating further, it seems that even a database adapter select is not working correctly. Consider the following table:
create table test_merge (
id varchar2(255) primary key,
text varchar2(255)
);And I have inserted a record with id = "1" and text="abc"
If I create a BPEL process and add a database adapter (with only the select checkbox ticked) with the following SQL:
SELECT ID, TEXT FROM TEST_MERGE WHERE (ID = #id)If I invoke this adapter, passing in "1" as the id, then a record is returned, with the correct text (i.e. "abc") BUT the id returned is "-9900000000000000000000000000"
Can anyone explain why this is happening? -
Hi,
I have created one external content type in sharepoint designer to insert/update/delete table data.
This table contains Primary key constraint.
Then I have added this external content type to Sharepoint out of box List.
Insert/Update/Delete is working fine. But when I am trying to insert record with the same id which is already exist in table, page crashed and its giving me following error:
“Violation of PRIMARY KEY constraint 'PK_tbl_Accounts'. Cannot insert duplicate key in object 'dbo.tbl_Accounts'.
The duplicate key value is (1). The statement has been terminated.”
So I want to handle this exception. Can we show any popup message to hide this error?
Thanks & Regards
RajniAvoid entering of primary from form if possible.
if not try to customize the new form with infopath and place your custom logic there.

Creating entity beans with auto numbered primary key
I have two entity bean with a CMR between them. I am successfully creating the first one but when I try and create the child entity bean I get a NullPointerException.
Now I think this is because the gernerated code tries to get the primary key of the created entity bean and this is not set as it is set using a auto number in the database (An oracle sequence and trigger).
Is there anyway i can get round this problem?
Thanks in advance,
AdrianThis is the auto generated code:
public dmd.sync.ejbs.entity.AppliancePackInfoLocal create_Local(dmd.sync.dataobjects.dto.AppliancePackInfoDTO appliancePackInfoDTO, dmd.sync.ejbs.entity.AmppLocal amppLocal) throws javax.ejb.CreateException, java.rmi.RemoteException {
BeanO beanO = null;
dmd.sync.ejbs.entity.AppliancePackInfoLocal result = null;
boolean createFailed = false;
boolean preCreateFlag = false;
try {
beanO = super.createBeanO();
dmd.sync.ejbs.entity.AppliancePackInfoBean bean = (dmd.sync.ejbs.entity.AppliancePackInfoBean) beanO.getEnterpriseBean();
preCreateFlag = super.preEjbCreate(beanO);
bean.ejbCreate(appliancePackInfoDTO, amppLocal);
Object ejsKey = keyFromBean(bean);
result = (dmd.sync.ejbs.entity.AppliancePackInfoLocal) super.postCreate_Local(beanO, ejsKey, true);
bean.ejbPostCreate(appliancePackInfoDTO, amppLocal);
super.afterPostCreate(beanO, ejsKey);
It must be falling over on the last line as it calls the ejbPostCreate fine. -
Best practices with sequences and primary keys
We have a table of system logs that has a column called created_date. We also have a UI that displays these logs ordered by created_date. Sometimes, two rows have the exact same created_date down to the millisecond and are displayed in the UI in the wrong order. The suggestion was to order by primary key instead since the application uses an oracle sequence to insert records so the order of the primary key will be chronological. I felt this may be a bad idea as a best practice since the primary key should not be used to guarantee chronological order although in this particular application's case, since it is not a multi-threaded environment, it will work so we are proceeding with it.
The value for the created_date is NOT set at the database level (as sysdate) but rather by the application when it creates the object which is persisted by Hibernate. In a multi-threaded environment, thread A could create the object and then get blocked by thread B which is able to create the object and persist it with key N after which control returns to thread A it persists it with key N+1. In this scenario thread A has an earlier timestamp but a larger key so will be ordered before thread B which is in error.
I like to think of primary keys as solely something to be used for referential purposes at the database level rather than inferring application level meaning (like the larger the key the more recent the record etc.). What do you guys think? Am I being too rigorous in my views here? Or perhaps I am even mistaken in how I interpret this?>
I think the chronological order of records should be using a timestamp (i.e. "order by created_date desc" etc.)
>
Not that old MYTH again! That has been busted so many times it's hard to believe anyone still wants to try to do that.
Times are in chronological order: t1 is earlier (SYSDATE-wise) than t2 which is earlier than t3, etc.
1. at time t1 session 1 does an insert of ONE record and provides SYSDATE in the INSERT statement (or using a trigger).
2. at time t3 session 2 does an insert of ONE record and provides SYSDATE
(which now has a value LATER than the value used by session 1) in the INSERT statement.
3. at time t5 session 2 COMMITs.
4. at time t7 session 1 COMMITs.
Tell us: which row was added FIRST?
If you extract data at time t4 you won't see ANY of those rows above since none were committed.
If you extract data at time t6 you will only see session 2 rows that were committed at time t5.
For example if you extract data at 2:01pm for the period 1pm thru 1:59pm and session 1 does an INSERT at 1:55pm but does not COMMIT until 2:05pm your extract will NOT include that data.
Even worse - your next extract wll pull data for 2pm thru 2:59pm and that extract will NOT include that data either since the SYSDATE value in the rows are 1:55pm.
The crux of the problem is that the SYSDATE value stored in the row is determined BEFORE the row is committed but the only values that can be queried are the ones that exist AFTER the row is committed.
About the best you, the user (i.e. not ORACLE the superuser), can do is to
1. create the table with ROWDEPENDENCIES
2. force delayed-block cleanout prior to selecting data
3. use ORA_ROWSCN to determine the order that rows were inserted or modified
As luck would have it there is a thread discussing just that in the Database - General forum here:
ORA_ROWSCN keeps increasing without any DML -
How do I Create an AutoIncrement on a Primary key Default
I am new to Oracle and need to know how to create a table that uses an automatic incrementation on a primay key for it's default. I need the uniqueness automatically managed by the DBMS.. This activity is know as setting the Column (primary key with identity) in Ms-SQL..
Your help would be appreciated greatly....
Thanks....you will have to create a sequence and a trigger
CREATE SEQUENCE <SEQUENCE NAME>
INCREMENT BY 1
START WITH 1
NOCACHE
/this sequence will guarantee that each requested number is unique
the trigger will select from this sequence and insert the obtained value in the new record
CREATE OR REPLACE TRIGGER <TRIGGER NAME>
BEFORE INSERT ON <TABLE NAME>
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
select
<SEQUENCE NAME>.nextval
into
:NEW.<COLUMN NAME>
from
dual;
END;
[/CODE]
this will always take the value from the sequence, even if you already provided a value yourself
(otherwise you will first have to test if :NEW.<column name> is null, but I wouldn't do this for a key column.
if you need the generated key back for further processing (inserting it into a child table for example), you can use the returning clause on the insert statement
see the oracle documentation for more information about sequences, triggers and the returning clause

Master Detail Forms with 2 composite primary keys - Is there a workaround?
Hello All,
I have been searching for a workaround to the maximum 2 part primary key restriction on the multi-row updates, and master-detail forms, and am hoping that someone can help me. I am using HTMLDB v2.0.0.00.49 with IE 6 against a 9.2 DB.
I successfully implemented the workaround of Fred Stoopendaal's (see Updata PK on HTML DB ) and it works fine for single page multi-record updateable forms, but alas I haven't been able to extend it to master detail forms (I think it is something to do with Oracle not allowing the "returning" clause on views).
Here is what I tried:
two tables, one with a 2 part composite primary key, which is the master table, and a detail table with 3 part composite primary key -
--------- BEGIN SQL ---------
create table master_table
( master_col1 number
, master_col2 number
, master_col3 varchar2(30)
, constraint master_pk primary key (master_col1,master_col2));
create table detail_table
(detail_col1 number
,detail_col2 number
,detail_col3 number
,detail_col4 varchar2(30)
, constraint detail_pk primary key(detail_col1,detail_col2,detail_col3)
, constraint master_detail_fk foreign key (detail_col1,detail_col2) references master_table(master_col1,master_col2));
create or replace view v_master_table as
select rowid mata_rowid,mata.*
from master_table mata;
create or replace view v_detail_table as
select rowid deta_rowid,
(select rowid from master_table mata where mata.master_col1 = deta.detail_col1 and mata.master_col2 = deta.detail_col2) deta_mata_rowid
, deta.*
from detail_table deta;
create or replace trigger mata_ins_upd_trg
instead of insert or update on v_master_table
referencing new as new old as old
for each row
begin
if inserting then
insert into master_table (master_col1, master_col2, master_col3)
values (:new.master_col1, :new.master_col2, :new.master_col3);
end if;
if updating then
update master_table
set master_col1 = :new.master_col1,
master_col2 = :new.master_col2,
master_col3 = :new.master_col3
where rowid = :old.mata_rowid;
end if;
end;
create or replace trigger deta_ins_upd_trg
instead of insert or update on v_detail_table
referencing new as new old as old
for each row
begin
if inserting then
insert into detail_table ( detail_col1, detail_col2, detail_col3, detail_col4)
values (:new.detail_col1, :new.detail_col2, :new.detail_col3, :new.detail_col4);
end if;
if updating then
update detail_table
set detail_col1 = :new.detail_col1,
detail_col2 = :new.detail_col2,
detail_col3 = :new.detail_col3,
detail_col4 = :new.detail_col4
where rowid = :old.deta_rowid;
end if;
end;
--------- END SQL ---------
Then I created a master-detail form in Apex on the two views, using the mata_rowid and deta_rowid as primary keys, and mata_rowid=deta_mata_rowid as the link. I realise that using a function to fetch the master rowid within the detail view query is costly, but it was my intention to modify the record fetch queries to use the real FK columns once things were up and running.
It seems to generate the pages ok, and I can insert/update master table records, but as soon as I modify records in the detail table things go a bit haywire. I can't find any documentation on how the inbuilt MRU/MRD logic works, so can't figure out the issue.
Can anyone out there tell me what the problem is with the logic above, or if they have come up with a neat solution to this annoying limitation. I know that many will say that I should modify the data model to use surrogate primary keys, but many of the uses for HTMLDB are new interfaces for old schemas, so a workaround that doesn't involve wholesale data model changes would be preferable.
Thanks in advance,
Mike CretanHi, this is likely not the most elegant way...but perhaps the simplest -- and I didn't have much time to play.
I used Wizard to create two separate Master Detail forms, each with a separate detail table. Thus I ended up with four pages:
Page "A" - "Selector" page for Master (Report), with Edit link driving to Detail-1
Page "B" - Editable Master/Detail-1 page (HTML / Report)
Page "C" - "Selector" page for Master (Report), with Edit link driving to Detail-2
Page "D" - Editable Master/Detail-2 page (HTML / Report)
Then I selected the primary key column TWICE on the Report on Page A. Modified the second instance of this column to navigate to Page D (passing primary key) exactly the way the original instance of this column navigates to Page B. Then I deleted Page C.
Since you can have only one Tabular Entry form per page, this seemed the best way to drive two separate detail tables from a common interface. -

Problem with foreign and primary keys migration from SQL Server to Oracle
Hi folks, i'm using SQL Developer to migrate from a SQL Server database to Oracle and i'm stuck with a couple issues:
The worst of them so far is the fact that i can't migrate any of the PKs and FKs. After successfully capturing the SQL Server DB model and converting it to Oracle, when the tool generates the scripts, all ALTER TABLE queries that add the PKs and FKs have their target columns duplicated.
for example: when i'm trying to migrate a simple table that contains an Id (PK) and Name columns, the tool generates the following scripts:
PROMPT Creating Table TestTable...
CREATE TABLE TestTable (
Id NUMBER(10,0) NOT NULL,
Name VARCHAR2 NOT NULL
PROMPT Creating Primary Key Constraint PK_TestTable on table TestTable ...
ALTER TABLE TestTable
ADD CONSTRAINT PK_TestTable PRIMARY KEY
Id,
Id
ENABLE
As for the FKs, the tool duplicates the columns as well:
ALTER TABLE SomeTable
ADD CONSTRAINT FK_SomeTable_SomeTable2 FOREIGN KEY
SomeTable2Id,
SomeTable2Id
REFERENCES SomeTable2
Id,
Id
ENABLE
Does anyone have a clue on how to solve these issues? I'd be greatly thankful for any answers!Hi Fernando,
I was unable to replicate this issue. My primary / foreign keys where defined using unique columns.
PROMPT Creating Primary Key Constraint PK_Suppliers on table Suppliers ...
ALTER TABLE Suppliers
ADD CONSTRAINT PK_Suppliers PRIMARY KEY
SupplierID
ENABLE
I tried a few things like
capturing twice and renaming both models the same
renaming the converted models
but with no luck.
I think this issue is occuring either at the capture or convert phase.
1) Are you performing the capture online or offline?
2) Can you provide a the entire DDL for one of these tables and its indexes to see if I can replicate?
3) Did the capture or convert fail or have to be redone at any stage ?
I all else fails I would attempt a capture and convert again using a brand new repository (create a new schema in Oracle and associate the migration repository with it).

Creating a script for a PRIMARY KEY USING INDEX SORT doesn't work
Probably a bug.
h1. Environment
Application: Oracle SQL Developer Data Modeler
Version: 3.0.0.655
h1. Test Case:
1. Create a new table TRANSACTIONS with some columns.
2. Mark one of numeric columns as the primary key - PK_TRANSACTIONS.
3. Go to Physical Models and create new Oracle Database 11g.
4. Go to Physical Models -> Oracle Database 11g -> Tables -> TRANSACTIONS -> Primary Keys -> PK_TRANSACTIONS -> Properties:
a) on General tab set Using Index to BY INDEX NAME
b) on Using Index tab choose a tablespace
c) on Using Index tab set Index Sort to SORTED.
5. Export the schema to DDL script. For the primary key you will get something like this:
ALTER TABLE TRANSACTION
ADD CONSTRAINT PK_TRANSACTION PRIMARY KEY ( TRAN_ID ) DEFERRABLE
USING INDEX
PCTFREE 10
MAXTRANS 255
TABLESPACE TBSPC_INDX
LOGGING
STORAGE (
INITIAL 65536
NEXT 1048576
PCTINCREASE 0
MINEXTENTS 1
MAXEXTENTS 2147483645
FREELISTS 1
FREELIST GROUPS 1
BUFFER_POOL DEFAULT
) SORTED
h1. Reason of failure
The script will fail because SORTED is not allowed here. It should be SORT.
Additionally, the default behaviour for Data Modeler is to set Index Sort to NO but default setting for Oracle database 11g is SORT. Shouldn't Data Modeler use SORT as the default value?
Edited by: user7420841 on 2011-05-07 03:15Hi,
Thanks for reporting this problem. As you say, it should be SORT rather than SORTED. I have logged a bug on this.
I also agree that, for consistency with the database default, it would be better to have SORT as the default in Data Modeler.

Delete records on basis of primary key.
HI all,
I need an ODI code so that i Should delete the record from target table on the basis of primay key with the reference of I$ table.
for example ..
T is target table & I$T is IKm table.
T has primary key P and I$t is also primay key.
So catually the code should be
delete from T where T.P <> I$.P
I wnat to insert the ODI code in IKM .
I had tried something like but it doesnt work
delete from <%=snpRef.getTable("L","TARG_NAME","A")%>
where <%=snpRef.getColList("", "[COL_NAME]\t <> :[COL_NAME]", "\nand\t", "", "(UK)")%>
Please sussgest.
Edited by: neeraj_singh on Dec 1, 2008 12:01 AMHi,
Use:
delete from <%=snpRef.getTable("L","TARG_NAME","A")%>
where <%=snpRef.getColList("(", "COL_NAME", ",", ") in ", "(UK)")%>
(select <%=snpRef.getColList("", "COL_NAME", ",", "", "(UK)")%> from <%=snpRef.getTable("L", "INT_NAME", "A")%>)
That code will give what you need...

Insert record and return the primary key
Okay, I need to insert a record into a MSSQL database and return the primary key of that record. Im using the following code which is obviously wrong as I'm getting either 'NULL' or 'com.microsoft.jdbc.base.BaseResultSet@1d520c4' returned depending on the ways I've tried. The primary key is an int value called clientID which is incremented by one each time a new record is added.
// set the prepared statement
String sql="INSERT INTO Client(username, country, clientIP, browser, os) VALUES(?,?,?,?,?)";
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setString(1, inUserName);
pstmt.setString(2, inCountry);
pstmt.setString(3, inClientIP);
pstmt.setString(4, inBrowser);
pstmt.setString(5, inOS);
// Insert the row
pstmt.executeUpdate();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT SCOPE_IDENTITY()");
System.out.println("Result "+rs);The primary key value is needed so that it can be used as a foregin key in another table. Am I going about this the correct way? Any help, pointers or code fixing would be appreciated.....Yes. I tried this way but I only ever get the answer
of 0 when i print our the result! Not really sure
whats happening.That's because you don't print a ResultSet like that. In order to get the key out, you have to do this:
int key = 0;
while (rs.next())
key = rs.getInt(1);What were you thinking with your code?
You might want to do this in a transaction. If the INSERT fails, you'll want to roll back.
The "select @@identity" is correct for M$ Access, SQL Server, and Sybase. I believe it's also correct for MySQL, but I'm not 100% certain of that.
