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.

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?
Rich PPlease follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

I am doing DataBase Lookup in XI
First i have created a Table in Database( CheckUser) which has two fields UserName and PhoneNumber and then i have created
I have created one Communication Channel For Reciever Adapter .
I have given the parameters like this
JDBC Driver : com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection : jdbc:microsoft:sqlserver://10.7.1.43:1433;DatabaseName=Ravi;
UserName.... sa
password.... sa
persistence : Database
Database Table Name : CheckUser
Key column name and Value column name i left blank and activated
and then
I have created
Data Types : Source ...... UserName
Destination.... PhoneNumber
Message Types
Message Interfaces
In Message Mapping
I have created one User Defined function DBProcessing_SpecialAPI().This method will get the data from the database....
In this function i have written the following code
//write your code here
String query = " ";
Channel channel = null;
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
query = "select Password from CheckUser where UserName = ' " +UserName[0]+ " ' ";
try {
channel = LookupService.getChannel("Ravi","CC_JDBC");
accessor = LookupService.getDataBaseAccessor(channel);
resultSet = accessor.execute(query);
for(Iterator rows = resultSet.getRows();rows.hasNext();){
Map rowMap = (Map)rows.next();
result.addValue((String)rowMap.get("Password"));
catch(Exception e){
result.addValue(e.getMessage());
finally{
try{
if(accessor != null)
accessor.close();
}catch(Exception e){
result.addValue(e.getMessage());
And the i have mapped like this
UserName -
> DBProcessing_SpecialAPI----
>PhoneNumber
when i am testing this mapping i am getting the following error

Partition key on non primary key column
I have scenario where the table has defined non primary key column as "partition key".
I was wondering how it will affect the purge/archive process if the index and table are using different column (they are not aligned)?
What should be the solution to this scenario?
Can I use the non primary key column as partition key? Is this affect purging/archiving or switching -IN or OUT partitions?
Here is the article which Im following but didn't get the precise answer:
"When the indexes and the table use the same partitioning function and columns in the same order, the table and index
are aligned."
https://msdn.microsoft.com/en-US/library/ms345146%28v=SQL.90%29.aspx?f=255&MSPPError=-2147217396#sql2k5parti_topic9
Look at "Index
Partitioning" and "Defining
the Partitioning Key" section.
ZKIf it non aligned, you cannot do switching in or out. to switch, you should have aligned partitons.
Hope it Helps!! -

SQL Data Sync - column type invalid for use as a key column
Hello,
our sync group is failing to do the sync. Here's a tracingID:
For more information, provide tracing ID ‘e3e568b5-140a-4ae5-a4c8-c178c6bf805d’ to customer support.
I must say, that the column in DB is not a PK or INDEX-ed, it was initially VARCHAR(MAX), after some reading I changed it to VARCHAR(200) and later to TEXT, but the result of syncing is still the same.
Thank you,
BojanHi Bojan,
The error “column type invalid for use as a key column” could be due to the existence of unsupported data types or column properties when implementing the synchronization. I recommend you check your database according to this article:
SQL Database Data Types supported by SQL Data Sync.
Besides, before you design and implement a data synchronization plan, please check the following articles about system requirements for SQL Data Sync and so on.
System Requirements for SQL Data Sync

Key Column Value in Geometry Theme
Hi,
I have serveral predefined ThemeBasedFOI Layer like this:
<?xml version="1.0" standalone="yes"?>
<styling_rules key_column="ID">
<hidden_info>
<field column="BAUFELDNUMMER" name="Baufeld-Nr."/>
<field column="FLAECHE_TXT" name="Fläche (m²)"/>
</hidden_info>
<rule>
<features style="C.QY_EG_BAUFELDGRENZE"> (FLAECHE >= :1 AND FLAECHE <= :2) </features>
<label column="BAUFELDNUMMER" style="T.GP_BAUFELDNR"> 1 </label>
</rule>
</styling_rules>
How can I access the value of the key column of each feature in the themebasedFOI layer?
What I'm trying to do is calling MVThemeBasedFOI.getFOIData(). As a result i'm getting an Array of FOI data. Each element has an id-property, but unfortunately that ID is not the database ID i'm looking for. It looks likes "AAARYUAAJAAADBOAAN".
Thanks
DominikThe id value of the FOI data element should be the value of whatever column set as key_column. What's the mapviewer version? Did you restart mapviewer or clear the metadata cache after making changes to the themes?

Hi together,
I am using class CL_SALV_TABLE for displaying ALV outputs.
I´ve defined several key-columns (method 'set_key') and use method 'set_key_fixation' .
Since 'set_key_fixation' apparently only works when (at least) one key column is beeing display
as the first column (position 1 of the ALV output table) I want to freeze the postion of the key column
(...so that you can´t remove the column or move the column to another position)
Any idea?
Thanks vor any helpHi,
This is probably another issue with SALV class... You could still grab a cl_gui_alv_grid object from your salv adapter and play with methods from this class (e.g. SET_FIXED_COLS)
have a look to this blog: Power of ABAP Objects: Overcome the Restrictions of SALV Model
Here we bypass the restrictions of the SALV model to enable the editable functionnality... guess you could work similarily for your issue...

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
HermanHi 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. -
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.

EDIT: Updated the log because I found out that I had made a small change to the original Test Case while I was trying to find a workaround. The current log is produced by the EXACT Test Case I described in my previous posts.

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 ApteHi 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. -
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

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..
ThanksHi 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 ..
