Get the primary key

Hello,
I would like to get the primary key of a MS Access table, but the DatabaseMetaData.getPrimaryKeys(...) doesn't work. An exception is thrown.
Anybody knows how to get the primary key of a MS Access table?
Thanks
Arno

Which code threw which exception?
Searching this forum for
Access primary
could help, too.

How to get the PRIMARY KEY of a table at runtime ???

Hi everybody,
My requirement is to update a z-table at runtime according to the data given ata runtime. So the main difficulties for me is that whenever I tried to update the table based on the data given in UI many rows are getting updated as these fields are not unique. So I think if I can get the PRIMARY KEY along with these given fields then I can update only one row at a time.
So Can anyone suggest me how to get PRIMARY KEY of a table based on the data in UI..??
Any suggestions will be appreciated..
Thanks,
Sekhar

U will get primary keys of transparent tables using FM "REUSE_FIELDCALATLOG_MERGE".
pass tyour table name and u will get fieldcatalog filled. In tht their is a field called "KEY" if it has 'X' then tht field is a primary key of transparent tables & if it has "space" then it is not a primary key...
Or else you can try with 'DDIF_TABT_GET'
Or try this code
PARAMETERS: p_table TYPE tabname OBLIGATORY.
DATA: go_strucdescr   TYPE REF TO cl_abap_structdescr,
      gt_tab_fields   TYPE ddfields.
FIELD-SYMBOLS: <gwa_tab_field> TYPE dfies.
TRY .
*   Get the details of the DDIC table
    go_strucdescr ?= cl_abap_elemdescr=>describe_by_name( p_table ).
CATCH cx_sy_move_cast_error .
    MESSAGE 'Error while casting' TYPE 'S'. RETURN.
ENDTRY.
* Check if input is a DDIC table
CHECK go_strucdescr->is_ddic_type( ) = 'X'.
* Get the details of the table fields
gt_tab_fields = go_strucdescr->get_ddic_field_list( ).
* Display the Key fields of the table
LOOP AT gt_tab_fields ASSIGNING <gwa_tab_field> WHERE keyflag = 'X'.
WRITE: / <gwa_tab_field>-fieldname.
ENDLOOP.

Getting the primary key from order form

Does anyone know how to get the primary key (DocEntry) off of the order form for an existing order? I don't really want to use the DocNum field since it is not the primary key and theoretically two different orders could have the same DocNum. Thanks in advance for your help.

Hi Joe,
DocEntry and DocNum values are unique, so you cannot have in db 2 orders with the same DocNum. It's possible, that DocEntry and DocNum values can vary.
If you know the DocNum value (f.e. from Order's Form), you can simple use RecordSet object:
Dim sQuery as String
Dim oOrder as SAPbobsCOM.Documents
Dim oRecordSet As SAPbobsCOM.Recordset
Set oOrder = oCompany.GetBusinessObject(oOrders)
Set oRecordSet = oCompany.GetBusinessObject(BoRecordset)
sQuery = "Select DocEntry From ORDR Where DocNum = '" & DocNumber & "'"
oRecordSet.doQuery sQuery
If oRecordSet.RecordCount > 0 Then
oOrder.GetByKey(oRecordSet.Fields(0).Value)
End If
And this should work.

Libor.

How to get the Primary key from Synonym

Hi ,
I want to get the Primary Keys for my tables . I used
java.sql.DatabaseMetaData databasemetadata = connection.getMetaData();
    ResultSet rs = databasemetadata.getTables(null, null, "%", null);
rs.next();
    System.out.println(" TABLE_CAT "+ rs.getString(1));
    System.out.println(" TABLE_SCHEM "+rs.getString(2));
    System.out.println(" TABLE_NAME "+rs.getString(3));
    System.out.println(" TABLE_TYPE "+rs.getString(4));
    System.out.println(" REMARKS "+rs.getString(5)); gives :
TABLE_CAT null
TABLE_SCHEM PROGRESS
TABLE_NAME ApplicConv
TABLE_TYPE SYNONYM
REMARKS null
Now if I use :
rs = databasemetadata.getPrimaryKeys(null,"PROGRESS","Applicconv");
System.out.println("Is result set Non empty "+rs.next()); gives :
Is ResultSet non empty false .
Can you tell me why this result is empty? Is it because of my table is a Synonym?
If it is Synonym how to get the primary key ?

You can use DatabaseMetaData#getPrimaryKeys.

How to get the primary key names right for child tables?

I have a logical model with a parent table and two child tables. The engineering strategy is "table per child". The parent has an primary key attribute. This is a screen shot:
https://lh5.googleusercontent.com/-iKMtA3Say5c/UIkG1iktgEI/AAAAAAAAAtc/mrwFeHm4gi4/s800/child_pk_log.png
When I engineer the model I get two primary keys with the same name name, which is the name of the parent:
https://lh3.googleusercontent.com/-N88a9VwoPKw/UIkG1spbXpI/AAAAAAAAAtY/eonf8WdUZ6I/s800/child_pk_rel.png
The correct names would be CHILD1_PK and CHILD2_PK. I can change the relational model by applying the naming rules but the next engineering will trash the names again.
How can I fix this?

Hi,
the problem with PK name is fixed in Data Modeler 3.2.
You can change PK name in relational model it won't be changed on next engineering

How to find out the primary key of oracle apps tables

Hii,,
My Question is How to find the primary key in the apps table...Is there any Query or other way to find out???
for eg.
I want to find out the primary key of the AP_INVOICES_ALL table...just tell me how can i get the primary key of this table.
I am currently using toad for the query..
Please guide me...

you can define the primary key when you create table
or add the primary key after the table creation by 'ALTER TABLE ... ADD constraint pk_nme primary key (col1, col2)';
you could use below sql to check the detail of primary key:
1) check out the table definition directly:
select dbms_metadata.get_ddl('TABLE','EMP') FROM DUAL;
2) check out the columns of primary key:
select * from user_constraints where constraint_type='P' AND table_NAME='EMP';
select * from user_cons_columns where CONSTRAINT_NAME='PK_EMP';And BTW, it is madam, not sir. :)

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

Getting Too many objects match the primary key oracle.jbo.Key...

Hi,
I am working on jDEV Version 11.1.1.2.0. In one of my page I am getting exception like "*Too many objects match the primary key oracle.jbo.Key......*".
I have a Items EO and it's Child EO. I am using view criteria in Items VO and drag and dropped this as a Query panel (search criteria). On the right side top I am displaying results in a table. Below I have a Master form and Child table where users can add / edit the Model and it's child values. When user clicks on Save button I am calling BPELprocess (WSDL) which inserts into 3 other systems and return me the message. After Clicking the Save button and displaying the message if I search for the same model (which I created) then it will throw error like above. If I search for different Model it won't throw the error.
For example I have created "TestModel" and If I type letter "T"in Input box and search then it will throw error. If I search for some other models which are not starting with letter "T" then it works fine.
Any idea what may be the reason? Instead of calling services in the Save button I drag and dropped "Commit" button and tested then it works fine.
This is really critical for my project. It would be great if someone can help me on this.
Thanks

JBO-27102: DeadViewRowAccessException
Reason: Trying to access a ViewRow which is part of an obsolete/invalid collection. This could happen if a reference to the ViewRow is held by some business logic while the containing view object was removed.
Solution: Find the referenced ViewRow either by re-querying or using findByKey methods to get a valid reference to the ViewRow. instead of create() can you try createInsert() or createAndInitRow()

Parameters in Url..how do I use login information to insert the primary key

Uggg, it is 3 am, I am so tired. Please help.
I have made a registration page for my site. Hurray it works.
Login Page. It works
Protected some pages. Works
Now I am trying to make a page that the users can go to and update their user information. User name, password, email ect.
I can get it to prepopulate if I put ?id=3, or someother primary key in the url by hand.....and it does update the data.... but I can't, for the life of me, figure out how to make it use the users login information to get and insert the primary key in the url from the link to the update page.
I have used the hyperlink box and chose the updateaccount.php file, then went to parameters and selected Name: id Value: I chose id from the dropdown from the data base. This puts in an echo that looks like it should work. NO SUCH LUCK.
Pleeeese!!! What am I doing wrong.
I am a total novice. Done a few static sites. So please speak slowly.
Thanks sooooo much

I really can´t recommend exposing critical stuff like e.g. the user´s login_id in the URL, because once it´s visible, it can be changed by anyone. Better insert the Session Variable kt_login_id, which will only be availabe on a custom PHP page when inserting...
<?php session_start(); ?>
...on line 1 of this document.

Using a custom PL/SQL to populate the primary key in a tabular form

Brian - Sometimes whitespace at the end of the block causes this. Be sure to trim everything after the last semicolon including tabs and newlines.

Error while creating the Unique Index of the Primary Key of an Item

Hi all,
I have deployed a new item (CO_CONTRACTUNIT_PRODUCT) in my publication. The deploy appears to be successfull as the item can be seen in the repository through the Mobile Manager.
The problem occurs when i sync my local DB to get the item offline. While synchronizing, the following error appears, both in the sync window and the log file ol_sync.log.
"ERROR",POL-5130,"11/09/2010 11:43:52","table or view %s.%s not found:CO_CONTRACTUNIT_PRODUCT,CO_CONTRACTID,OD_PRODUCTID,CO_CONTRACTUNITID","DB_ROSHNI"
However, the debug file gives this other error regarding this table.
ALL_INDEX:CREATE UNIQUE INDEX "TPCO_CONTRACTUNIT_PRODUCT_PK" ON CO_CONTRACTUNIT_PRODUCT (CO_CONTRACTID,OD_PRODUCTID,CO_CONTRACTUNITID) -5130Error at C:\ADE\omeprod_ol103021\olite\db\build\win\ocapi\..\..\..\src\ocapi\allindexes.cpp line:329 rc:-5130
Build date Mar 29 2010
okErr=(table or view %s.%s not found)
mess=(CO_CONTRACTUNIT_PRODUCT,CO_CONTRACTID,OD_PRODUCTID,CO_CONTRACTUNITID)
AddLog(-5130 "ERROR",POL-5130,"11/09/2010 11:43:52","table or view %s.%s not found:CO_CONTRACTUNIT_PRODUCT,CO_CONTRACTID,OD_PRODUCTID,CO_CONTRACTUNITID","DB_ROSHNI")
But the index that is being created and is giving the error is the index created automatically with the Primary Key of the table, and so nothing has been modified in that.
The primary key of the table is created with the three columns that are part of the index that is returning the error.
As I could not solve the error, I tried to drop and re-create the item in the repository, but no luck. As a last option, i tried to remove the item from the repository to be able to sync properly again (just like before creating the item), but the error still happens.
Another weird point is that i have tried creating the item in another publication of another database (but with almost equal items), and the item could was downloaded to my local DB without any problem, which makes this problem still more bizarre.
What can it be?
Any help would be great!

have you tried unistalling the client and reinstalling it?
schema evolution changes are not always handled correctly please check thread:
Modification of publication item into Mobile Server
i quote from rekounas instructions:
If you are just adding a field, you should only have to run the alter publication item API call.
Here is an old note on schema evolution on different scenarios. The names for the APIs that they use are now deprecated. Use the ConsolidatorManager class and call the method alterPublicationItem("PUBLICATION_ITEM_NAME", "SELECT STMT") :
A) Add column
1. Upload all client data. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Change the Oracle8i/9i database schema (add column)
4. Create a Java program to call the Consolidator Admin API AlterPublicationItem()
5. Start Mobile Server
6. Execute a sync from the client
7. The new column should be seen on the client. Use MSQL to check snapshot definitions.
B) Drop column
1. Upload all client data. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Delete column of the base table in the Oracle database schema
4. Create a Java program to call the Consolidator Admin API DropPublicationItem()
5. Create a Java program to call the Consolidator Admin API CreatePublicationItem() and AddPublicationItem().
6. Start Mobile Server
7. Execute a sync from the client
8. The new column should be seen on the cliet. Use MSQL to check snapshot definitions.
C) Change column datatype
Changing datatypes in a repliatated system is not an easy task. You have to follow certain procedures in order to make it to work. Use DropPublicationItem, CreatePublicationItem and AddPublicationItem methods from the Consolidator Admin API. You must stop/start Mobile Server listener to refresh the cache.
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Drop/create column (do not use conversion procudures) at the base table
4. Call DropPublicationItem(). Check if the ErrorQueue and InQueue no longer exist.
5. Call CreatePublicationItem() and AddPublicationItem(). Check if the ErrorQueue and InQueue reflect the new column datatype
6. Start Mobile Server. This automatically resumes application
7. Client executes sync. This should drop the old snapshot and recreate the new snapshot. Use MSQL to check
snapshot definitions.
D) Drop table
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Drop base table
4. Call DropPublicationItem(). Check if the ErrorQueue and InQueue no longer exist.
5. Start Mobile Server. This automatically resumes application
6. Client executes sync. This should drop the old snapshot. Use MSQL to check snapshot definitions.
E) Add table
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Add new base table
4. Call CreatePublicationItem() and AddPublicationItem() method
5. Start Mobile Server. This automatically resumes application
6. Client executes sync. This should add the new snapshot. Use MSQL to check snapshot definitions.
F) Changing Primary Keys
Chaning PK is a severe operation which must be executed manually. A snapshot must be deleted and recreated to propagate the changes to the clients. This causes a full refresh on this snapshot.
1. Client syncs. Clients should not add new data until they are told by the administrator to sync again!!
2. Stop Mobile Server listener
3. Drop the snapshot using DropPublicationItem() method o
4. Alter the base table
5. Call CreatePublicationItem()and AddPublicationItem() methods for the altered table
6. Start Mobile Server. This automatically resumes application
7. Client executes sync. The old snapshot will be replaced by the new snapstot using a full refresh. Use MSQL to check snapshot definitions.
G) To Change a Table Weight =>
Follow the procedure below to change the Table Weight parameter. The table weight is used by the Mobile Server/Synchronization to determin the sequence in which client records are applied to the Oracle database.
1. Run MGP to apply any changes in the InQueue to the Oracle databse
2. Change table weight using SetTemplateItemMetadata() method
3. Add/change constraint on the the base table which reflects the change in table weight
4. Synchronize

Hi people..
I am building an interface which displays the database information...according to the specified datasource name..
Up till now i managed to display the different tables and the respective attributes...
Is there a way of how i can determine (through java code) if an attribute is the primary key or not of the corresponding table??
Thanks for your time..
