Determining the row id or primary key columns and values genericaly

Hi There
Does anyone perhaps know how to determine the rowid of the
currently selected row in a form, or alternatively the primary
key values/columns?
Regards
Herman

Hi Tranen,
you can view the constraints and respective columns by setting the
Table Shape Properties in the Property Inspector.
Select (all) the tables on the Diagram you want
In the Property Inspector,under Constraints -Set the 'Show Constraint Columns' to 'True',
Set 'Show Constraints' to 'True' .
Constraints (PK,UK,FK,Check)
Also Set the 'Show Columns' option to 'False' .This will be under display options in the Property inspector.
This should modify the Table shape in the diagram as follows:
<Table name>
<PK> PKName:Column1,Column2
<UK>UKName:Column3
<FK>FKname:Column1
are you looking for the same?
Thanks.

Automated row fetch / Complex primary key

I have a complex primary key made up of ticket_num, ticket_seq because there may be between 1-3 rows associated with one ticket_num.
The problem I am having is the automated row fetch errors out when trying to update a ticket with the following error even though the combination of ticket_num, and ticket_seq are unique, and ticket_num, ticket_seq are entered in the automated row fetch as primary key column, and secondary key column.
ORA-01422: exact fetch returns more than requested number of rows
Is there a way to put both columns as the primary key?

Thanks, Scott. I had the exact same problem, and your suggestion fixed it.
May I suggest that this is a bug in Apex? In the create application wizard, select "Add Page" -> "Report and Form", and select a table with a compound primary key consisting of two columns. Apex will create the report and the form, and will configure the ARF correctly in the form, but it does not specify a value for the second key in the Link Column section of the report attributes.
Thanks,
Mike

FillSchema picks too many primary key columns

I don't know whether this is an ODP.NET error or a Microsoft error.
Oracle9i Release 9.2.0.1.0
ODP.NET 9.2.0.4
.NET Framework 1.1
Create a table with one primary key column and one unique column and name the primary key column like the unique column with the suffix "_ID":
CREATE TABLE t_bib_uebertrag_kap(
&nbsp kapazitaet_id NUMBER(8) NOT NULL
&nbsp&nbsp CONSTRAINT pk_kapa primary key,
&nbsp kapazitaet VARCHAR2(15) NOT NULL
&nbsp&nbsp CONSTRAINT a_un_kapa unique,
&nbsp geschwindigkeit NUMBER(12) NOT NULL,
&nbsp bemerkung VARCHAR2(255)
After calling FillSchema on this table the PrimaryKey property of the DataTable contains 2 columns: KAPAZITAET_ID and KAPAZITAET.
The same happens with other tables and similar column names

Tony, I'm gonna find time to try this because I was thinking it probably would be a double check.
BUT... Oracle is written in C, and I imagine the extra check as a simple if comparison for the new value versus a constant NULL value. Kind of like checking for end of string. It's already doing things like checking datatypes and that as it inserts data, and I don't think this additional check (if it even exists) would add any significant overhead.
But unless I find a much larger performance hit than I expect, I'm gonna stick with creating the NOT NULL's explicitly. Good data modelling trumps small performance tricks for me.
My main worry is if/when somebody removes the primary key constraint (such as the example above where they might do a CREATE TABLE x AS SELECT * FROM y). Or if the data model gets updated to where the primary key becomes just a unique key, then the NOT NULL goes away when it shouldn't. I don't like basic table and column properties changing.
Okay.. test done. Ran about 31,000 records from dba_tables through an insert into two tables, both with primary keys and one with explicit NOT NULLs. No measurable difference in stats detected.
With NOT NULL and PRIMARY KEY:
call count cpu elapsed disk query current rows
Parse 1 0.35 0.35 0 0 0 0
Execute 1 1.88 1.83 0 24792 35887 30954
Fetch 0 0.00 0.00 0 0 0 0
total 2 2.24 2.18 0 24792 35887 30954
Now with only PRIMARY KEY.

"Item Containing Primary Key Column Value" does not display records

Hello,
We are developing a new page where an "Automated Row Fetch" process is needed.
With other pages we experienced no issues. But with a new one, when defining the value for the field “Item Containing Primary Key Column Value”, Apex displays no rows.
As far as we know, Apex should display all the fields defined for the page. Is there any property which affects the fields visibility?
The affected page has textarea and text fields.
Thanks in advance.

Hello,
Sorry, we have already detected that the problem was at field definition.
Fields should be defined as "Source Type: Database Column". They were wrong defined.
Thanks.

Switch the sequence of Primary Key Columns

Hi MaxDB experts,
As part of our product upgrade we've made a schema change to 10 of our database tables. Typically these tables contain about 5 million rows in them. The change involves switching the order of columns in the primary key (original order SampleTime, Id; new order would be Id, SampleTime). What's the quickest way to achieve this?
So far I've tried the following approaches without much luck:
1. Use the "alter table alter primary key (new seuqence of columns)". Takes an average of 1 hour per table.
2. Copy original table content into another table with "insert into newTable (select * from existingTable)" command. Takes the same amount of time as #1
3. Tried using "Export Table" option presented by the "loadercli". Unfortunately, exported data can not be imported to a table with a different schema (in our case changed primary key column sequence).
What else can we try? Any advise / direction would be greatly appreciated. Thanks for your time.
Sincerely,
Sameer Apte

Hi there,
ok, I assume that you figured out that you like to have data entries belonging to a specific ID stored rather nearby than scattered around in the table by TIMESTAMP or that you have more queries that specify the ID but not the TIMESTAMP.
Both would be good reasons to perform such a change.
Concerning the speed: basically things won't get any faster than ALTER TABLE or INSERT (SELECT * FROM)...
The ALTER TABLE approach would have the advantage to be transactional atomic and simple to use.
The INSERT approach would enable the use of the PREFETCHING feature for the read-I/O on the source table.
So if you're just focussing on speed, then I'd recommend to:
setup a data cache that can hold both source and target tables im memory
enable prefetching by setting the parameter READAHEAD_TABLE_THRESHOLD to say 128 (be aware that you've to use MaxDB 7.6.05 or higher, but not 7.7.x for that!)
After you've copied each table, make sure to create the secondary indexes one by one since otherwise the internal parallelism won't be used.
regards,
Lars
p.s.
it is possible to export/import into different schemas - it's even supported via DB Studio.
Anyhow, it wouldn't make anything quicker for this case.

Primary key column as the key of the cache

Hi All,
I am implementing a cache backed by HibernateCacheStore for a table. Cache contains key as the primary key of the table and value as the entire row in object format. the primary key is generated by hibernate.
when i am inserting new rows through coherence (i.e cahce.put) what persistence strategy should is use to set the cache entries.
I cannot use cache.put (key, value) because key is the primary key of the table which is not generated yet.
and if i use the session.save(value) the persisted value is not in the cache.
is there any mechanism to map the cache key as the primary key column of the table.
Regards
S

Hi -
Using Hibernate as a CacheStore for Coherence, the key of the cache entry is also the key of the entity
being stored via Hibernate. For this reason keys for new cache entries must be generated ahead of time.
A UUID can be used. The commons component of the Incubator project has a key generation utility that
might be worth looking at.

Hi cant see the primary key column in master detail form

I have a master detail form .In the first master form i am unable to see the primary key
Now the form is built completley and i also will like to see the primary key column visible in master report
If i had set the primary key as rowid then i could have seen the primary key ..
Now i can see the pencil icon (The eidt row pencil icon) instead of the actual primary key column . .which is a number data..
I will like that too be visible ..Can any one guide what should i do for this..
Thanks

Hi Mat,,
I am using apex 4.2 db version 11g and in the first master page i had set the value of combo which is primary key column as text
But still iam not able to see the number ..Note if i recreate the form ..with rowid as primary key i am able to see the column since the pencil icon(edit icon) is on row id..
Currently All i see is the edit icon ..I need both the edit icon and also the number ..
Thanks

JPA: Attr ... mapped to a primary key column in the DB. Update not allowed.

Let me just say that I posted a bug report for this here:
https://glassfish.dev.java.net/issues/show_bug.cgi?id=3937
But I'm also posting the info here, so that people who search on this forum may get some help:
TopLink (both Essentials and 11g) has a problem with flushing entities
containing a self-reference relationship. When flushing, the following exception
occurs:
Exception [TOPLINK-7251] (Oracle TopLink Essentials - 2.1 (Build b14-fcs
(12/17/2007))): oracle.toplink.essentials.exceptions.ValidationException
Exception Description: The attribute [id] of class [test.jpa.entities.Person] is
mapped to a primary key column in the database. Updates are not allowed.
No manual updates have been made to ANY primary key.
What I'm doing is:
1. I instantiate a new entity.
2. I start a transaction
3. I persist the new entity.
4. I read an existing entity from the DB.
5. I let the existing entity point to the new entity via the self-reference
relationship.
6. I flush the persistence context.
7. I issue commit(), and the exception occurs. (I have provided the stack traces for various versions of TopLink below.)
This is a clear bug.
Here are some additional observations:
1. Reproduced on the following versions of TopLink:
1.1. Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007))
1.2. Oracle TopLink Essentials - 2.1 (Build b14-fcs (12/17/2007))
1.3. Oracle TopLink - 11g Technology Preview 3 (11.1.1.0.0) (Build 071214)
2. Reproducible both on Java SE and Java EE. (I tested on Oracle Application Server)
3. Reproducible with and without class weaving
4. Reproducible regardless of whether the JPA annotations are on fields or on
methods
5. Reproducible regardless of whether "cascade={CascadeType.PERSIST}" is used or
not.
6. Reproducible regardless of the fetch type of the self-reference relationship
(EAGER or LAZY).
Also:
1. Without flushing, the bug doesn't occur. That is, if I commit without
flushing, it works.
2. Without setting the self-reference relationship, the bug doesn't occur.
This is an issue that appears when using BOTH self-reference relationship AND
flushing.
Best regards,
Bisser
The message was edited by bisser:
Added info that the exception occurs "when I issue commit()" on step 7.

I'm extremely surprised that you couldn't reproduce the error. It's reproduced each time when I run the Test Scenario that I described above.
You could download a sample Eclipse project that reproduces the error from here: https://glassfish.dev.java.net/issues/show_bug.cgi?id=3937
For the log below I used TopLink, version: Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007)).
Could you, please, tell me what version you use and I will try the Test Case on it.

Knowing the primary key columns of the given table

Hi,
How can I get the primary key columns of the given table?
Regards,
Sachin R.K.

You can find the constraint_name from all_constraints/user_constraints for constraint_type = 'P' (which is the primary key constraint).
And then see which columns are in for the constriant_name
in all_cons_columns/user_cons_columns view.
Below is the example
select acc.column_name from
all_cons_columns acc, all_constraints ac
where acc.constraint_name = ac.constraint_name
and acc.table_name = 'DEPT' AND acc.owner = 'SCOTT'
and ac.constraint_type = 'P'
Hope this helps

How to know primary key column name form a table name in sql query

Suppose I only know the table name. How to get its primary key column name from the table name?
Thanks

Views don't have primary keys though their underlying tables might. You'd need to pick apart the view to determine where it's columns are coming from.
You can select the text of the view in question from user_views.

How to update primary key column

Hi,
Can you suggest me best workaround/algorithm for below task:
(Oracle 10g, Solaris OS.)
Situation:
Table P has primary key column "Code", child tables F1, F2, ..., F15 reference with foreign key column "P_Code" column "P.Code", and we don't know which of the child tables has data for particular "P.Code" value.
Task:
Change "P.Code" value from 100 to 200. So that result would be that record P[Code = 100] should be updated as:
update P set
Code = 200
where Code = 100;And child tables column "P_Code" should be updated as:
update F1, F2, .., F15 set
P_code = 200
where P_code = 100;The best solution would be that one very easily can repeat that task.

How to modify primary key column?

I want to modify one primary key column, But TT reported error.
How do I modify primary key column? Thanks first.

In TimesTen, the values in primary key columns cannot be updated (except for the trivial case where you update the value to the same value as it currently has). If you want to change the values stored in primary key columns the application must insert a new row with the new key values (and of course values for the other columns) and then delete the old row.

No Primary Key Column was set. (UPD_NO_PK_SET)

I'm trying to build an update record page that gets the primary key value passed from a dynamic edit selection. dynamic list is great..opens up to the update record page great...values filled in including the primary key...i can see the primary key value listed in the URL...but then i hit submit and I get:
No Primary Key Column was set. (UPD_NO_PK_SET)
I have seen this error posted a lot, but no concise solution..been working on this for days...Please please help..! i'm desperate!

Ok, I'm confused....with
 
 // Load the KT_back class
 require_once('includes/nxt/KT_back.php');
 
 removed all works great...the delete, the insert. When I do any of those desired functions, I do get back to the dynamic list page..however, I chose to edit say record 12 ..with only 10 showing per page so i'm on the second page...if i cancel..i jump back to record page one...Is that the functionality I'm losing?
 
 hope you dont mind, but I am trying to post the code?

Primary key column in manual tabular form

I am creating a manual tabular form and am unsure what to do for my primary key column. When I do this with the wizard, I'm allowed to specifiy a Primary Key Source Type and the Primary Key Source (my sequence). Is there a way to do this in a manual tabular form?
I'm creating the column with the call 'wwv_flow_item.display_and_save(2,hours_id) hours_id' but when I edit the 'Tabular Form Element' section, I don't have the Primary Key fields anywhere to edit...only Reference Table Owner, Reference Table/Column Name. Where can I specify the sequence?
Thanks,
Janel

In the process ApplyMRD, try specifying the 'Secondary Key Column' in the section 'Source: Multi Row Update and Delete' to the second key column in the tabular form.
I haven't tested this with your situation, but worth a shot.

Is there any restriction on the length of all Primary keys in a table

Hi all,
Is there any restriction on the length of all Primary keys in a data base table?
i have some 10 fields as primary key in a DB table and length exceeds 120 and getting a warning.
Please let me know will there be any problems in future with respect to the same?
With regards,
Sumanth

Well actually there are constraints like
Total of internal lengths of all primary key columns        1024 Bytes
Number of primary key columns per table                     512
For other information about SAP database please refer to http://sapdb.org/sap_db_features.htm
