When changing query data source property.....

hello folks,
I have this very weird behavior in oracle forms 10 g R2:
in my form I built a datablock " DB " based on a table " table1 ", in that datablock I added a push button that changed the query data source name of data block DB to " table2 " using the set_block_property() built-in, please note that table1 and table2 has the same structure.
When I query the table2, and if i try to update a record, the updates are not saved and I got the error ora - 0000 , It seems that after changing the query data source to table2, if i try to update a record, the locking is perform to table1 (the original query data source that the datablock is built in the first place) ....
Please can anyone help or explain me this behavior and what can i do to perform a workaround for it,,,,,
and than you in advance...

dear Mark,
What indicates that the record is locked? More information please. well if query the v$lock view or from the EM I can see that the lock is performed on the first table

About Query Data Source Columns property

Hello everyone,
I'm new to Oracle Forms version 10.1.0.2.
When I create a data block based on a table using Data Block Wizard, the block's Query Data Source Columns property is automatically populated with column definition entries corresponding to the columns of the base table.
I tried making changes to these entries, for example by changing the data types to wrong data types or even deleting them, and I found that those changes had no effect on the block at all. The form was still working as I wanted.
Please explain what is exactly the role of the block's Query Data Source Columns property.
Thank you very much.
p.s: The F1 key help says "The Query Data Source Columns property is valid only when the Query Data Source Type property is set to Table, Sub-query, or Procedure". So, please explain in each context of Query Data Source Type.

p.s: The F1 key help says "The Query Data Source Columns property is valid only when the Query Data Source Type property is set to Table, Sub-query, or Procedure". So, please explain in each context of Query Data Source Type.
IMHO those properties are very self-explaining: It is the data source of the block, or in other terms: how it is populated.
Table means the data block is based on a table and subsequently will be populated by
select col1, col2, col3 from your_table
With sub-query the block will be populated with your subquery; forms will issue
select col1, col2, col3 from (
-- this is your subquery
select col1, col2, col3 from tab1, tab2 where [....]
With Procedure in short you'd have a stored procedure which returns a ref cursor and the block will be populated by the ref cursor.
As for your question about the name: this actually should matter; the default is NULL which means that there needs to be a column which has the exact name as the item so in the above sample with table the item associated with your_table.col1 should be named col1. If it isn't the property should be named like the column. If this property also doesn't reflect the name this shouldn't work IMO.
cheers

Abnormal termination of runform when PROCEDURE is used as Query Data Source Type

I created a package with a procedure that returns a table of records. This
procedure tested OK in SQLPLUS. I then created a form and in this form a block
that used this procedure as the Query Data Source Name, and of course the Query
Data Source Type has been set to PROCEDURE. This form runs beautifully when the
number of records returned is small (a few hundreds). But when the number of
records is large (I have one case where the total number of records returned
was 11099) then it will crash. I also found that whenever this happens, there
will be a file in my C:\TEMP with funny namessuch as s90, s81, etc. They are
always the same size (5008 kBytes).
Anyone any ideas?

<BLOCKQUOTE>quote:<HR>Originally posted by Chandra movva([email protected]):
Create a view and base your block on view.That could solve the problem unless you have other requirements specifically.<HR></BLOCKQUOTE>
Chandra,
Thank you for your suggestion. Unfortunatel, we have requirements that translate to logics too complicated to be handled by views, and that is why we use PROCEDURES. This actually works very well and very fast, except when we have lots of records returned, then it fails. I am just wondering whether this is a configuration problem ???

Block Property (Query Data Source Type)

Hello Friends
I am using Forms 6i.oracle 9i.
in the Block Property Pallete under Query Data Source Type there
are 4 Type is mentioned.i have used Table,From Clause Query but yet to use Transactional Trigger and Procedure.How to use this two and it will be very kind enough if u give any example about these twos.
Regards

There's a whole bunch of explanation about this subject in the online help of Forms. Just select the Query Data Source Type property and press F1. The initial explanation is very limited but there are a number of useful links under "Related topics"

Setting Query Data Source Arguments Property for Block with TYPE Procedure

Hi,
I have a block whose type is 'Procedure', this returns a PL/SQL table.
I pass an IN OUT variable declared in the Package header and all works well.
What I need to know is how, if I have ANOTHER argument, how do I set it programatically prior to EXECUTE_QUERY.
I can see how to set the Name and Value manually at the "Query Data Source Arguments" property but if I need to set it dynamically in the code how would I do it.

Thanks,
Worked it out.
Set the VALUE to the name of a Global variable and populated the variable before executing the procedure.
Thanks

How to use 'query data source Name ' property in a block

I want to create a block using query and want to show the columns on a form.
Could you please tell me how can I do this?
Regards

Hi!
Create a new block manually.
Set the Query Data Source Type Property to FROM clause query.
In the Query Data Source Name Property write your query like you would
write it in sql*plus or toad but without a order by clause.
Set the DML Data Target Type Property to None.
Create items for the columns in your query.
May set the where clause and order by property of the block.
Build the form and execute a query in your new block.

Trying to change the data source for a Crystal Report.

The method below represents my best attempt to programatically change the data source of a Crystal Report. The goal is to have a routine that will update the data source for reports after they have been distributed to production servers. So far I have not been successful in saving the report back to the CMS. No exceptions are thrown, but when I view the Database Configuration of the report in the CMC nothing has changed.


Am I missing a step, or is there another way to accomplish this?


Thank you.

Justin,

Thank you for the reply. Time constraints have not allowed me to post back to this tread
till now. I will try your suggestion. My assumption is that Save the report back to the
info store refers to IInfoStore.commit(IInfoObjects).


I'm afraid that I do not understand why I don't want to change the report client document,
or why successfully exporting the report with the new login/password is not what I
want to do. Any explanation on that statement would be appreciated.


I did find a way to accomplish my goal. It involved adding the SSOKEY property to the
logon property bag. Below you'll see my revised code which modifies the report logon and
server. I have no idea what
this does, and SAP support has not been able to tell me why it works. However, what I
discovered is that if I changed the report option, Database Configuration -> When
viewing report:, in the CMS to Use same database logon as when report
is run from Prompt the user for database logon, then the
SSOKEY property had been added to the logon property bag having an empty string as its
value. This allowed me to successfullyupdate and save the modified logon back to the CMS.


So I took a chance and added code to always add the SSOKEY property with an empty string
as its value, and I could then successfully modify and save the report's logon info
and server. Again, I don't know what this means, but it has worked so far. If anyone has
some insight or comments, either are welcome. Thank you in advance.

Need to change report data source on reports in a copied universe

We are setting up a new testing environment. So I made a copy of our BO universe so we could have two different testing universes. I then created a copy of the data source database that will be used as the data source for the reports in the copied universe. The two different databases have the exact same tables, columns and indexes as the development database. The only difference will be the data inside the tables.
I now need to change the reports to use the new universe since the reports were written using the universe instead of using the database. I am not changing anything else in the reports. I just need them to run against a different Oracle database.
So I go into Crystal Reports version 11.5.0.313 and open the report up. I then go into Database fields in Field Explorer to change the data source. I then go to the Set Datasource Location screen. I open up the universe label by clicking on the plus sign and I select the copied universe. When I do that, the Business Objects Query panel screen opens up. Because I have switched universes, Crystal Reports wants me to reselect the columns and rebuild the query.
We have over three thousand reports so we are trying to avoid rebuilding them. I am looking for a better way to change what database a report runs against.
Note: All of the reports will be run ion demand. Nothing will be scheduled.
Any suggestions and information will be greatly appreciated.
Has anyone run into this? What was your solution to this problem?

Hi Joe,
Moved your post to the Universe Forum.
First you are using the original release of XI R2. You need to upgrade to Service Pack 6 by:
Run License Manager first to get the keycode if you don't have it on paper somewhere.
Then download these and uninstall then run full build first:

Crystal ActiveX Runtime Lib: Change text data source path at run time.

We have some PCs running Crystal Reports 10 and some running CR 9 and 8.5. For each PC, we set up a System DSN ODBC data source (in Control Panel - Administrative Tools) for pulling data from text files to
generate reports.
Recently we wrote some routines (see the Visual Basic example at the
end of this message) to change the path of the data files at runtime.
According to the Crystal Reports Technical Reference Guide, we may use
the method LogOnServer() of an Application object or an DatabaseTable
object. However, we find that this does not work: the PrintOut()
method only pulls data from the default path as configured for the
System DSN, not from the path passed as the third parameter of
LogOnServer(). It does not return any error message.
We have also tried to use SetTableLocation() method, and it still does
not work.
Would any experts examine our code below and advise what we are missing? Thanks.
For the following VB example, we have:
System DSN Name: AP_WORKSHEET
Driver: Microsoft Text Driver
Database Directory: D:\0ood2 (i.e. the default path)
Crystal Report Document: D:\3g\run\Vision\apcyto\Reports\crBlockWS.rpt
(Which specifies that the data source text file name is BlockWS.txt)
Purpose : We would like to read the data source text file from
D:\0ood1 instead of the default path.
Following is the code of the VB macro:
Sub test()
Rem In this version of the subroutine, we call
Rem DatabaseTable.LogOnServer() and "Rem"ed out
Rem Application.LogOnServer() and SetTableLocation().
Rem We have un"Rem"ed each of them and "Rem"ed others and try to run.
Rem In all runs, data are pulled from the default file
Rem D:\0ood2\BlockWS.txt instead of D:\0ood1\BlockWE.txt.
Dim crxapp As CRAXDRT.Application
Dim crxRep As CRAXDRT.Report
Dim crxDB As CRAXDRT.Database
Dim crxTab As CRAXDRT.DatabaseTable
Dim crxConnPs As CRAXDRT.ConnectionProperties
Dim crxConnP As CRAXDRT.ConnectionProperty
Dim apropSubLoc As String
Dim apropConnBufStr As String
Set crxapp = CreateObject("CrystalRuntime.Application")
Rem
crxapp.LogOnServer "p2sodbc.dll", "AP_WORKSHEET", "<CRWDC>DBQ=D:\0ood1",
Set crxRep = crxapp.OpenReport
("D:\3g\run\Vision\apcyto\Reports\crBlockWS.rpt")
Set crxDB = crxRep.Database
Set crxTab = crxRep.Database.Tables(1)
apropConnBufStr = crxTab.ConnectBufferString
apropSubLoc = crxTab.SubLocation
crxDB.LogOnServer "p2sodbc.dll", "AP_WORKSHEET", "<CRWDC>DBQ=D:\0ood1",
Rem crxTab.SetTableLocation "D:\0ood1\BlockWS.txt", apropSubLoc, "DSN="
Rem Set crxConnPs = crxTab.ConnectionProperties
Rem Set crxConnP = crxConnPs.Item("DSN")
Rem crxConnP.Value = "AP_WORKSHEET"
Rem Set crxConnP = crxConnPs.Item("Database")
Rem crxConnP.Value = "D:\0ood1\BlockWS.txt"
Rem crxTab.Location = "BlockWS.txt"
crxRep.DiscardSavedData
crxRep.PrinterSetup (0)
crxRep.PrintOut
End Sub
For VB macros, the problem exists in all of CR 8.5, 9 and 10. However,
for another platform we are using, Unify Vision 4GL, it works for CR
8.5 while not working for CR 9 and 10.
Following is the source code in Unify Vision 4GL. This language may
not be popular, but I thin you are about to see how it calls the
Runtime Library methods LogOnServer(), OpenReport(), PrinterSetup() and
PrintOut().

Can we change the Data source in AO ?

Hi Folks,
Environment: SAP HANA on AO
I have the following scenario , Am creating a report on one Calculation View: CV and have done some analysis where I have pulled in some dimensions and kept some background filters.
Now I have to generate the same report on another Calculation View: CV2 ( Similar to structure of CV ) and compare the reports. Is there any way to edit copy the previous report and change the data source? Can you guide me on that?
Regards,
Krishna Tangudu

Hi,
You can exchange the calc view by clicking on the button next to the data source name in the tab "components", but when you do this, the new data source will overwrite the settings and filters from the previous data source. So no, there is not a supported way of exchanging the datasource and keeping the filters of the previous data source.
Best regards,
Victor

Question on Dynamic Query Data Source and Form Folders in Oracle Forms 6i

Hi there -
I have one interesting requirement in Oracle Forms.
This is what I wanted to do.
1. Have a LOV and Go button on Form.
2. From LOV, I will select a pre-defined custom table and click Go.
3. Based on the selected custom table, I have to populate the Block (Tabular Format).
4. User should be able to do update, delete, insert on this block.
5. User should be able to use the Oracle Form folders functionality (select only necessary column and save views etc. Std folder functionality).
6. If user selects a different custom table name in the LOV on top, I need to refresh the data from the block based on this new table. Remaining functionality should be as it is (steps 3 to 5).
You can see here, I am going to have dynamic query data source (Table Name as well as column mapping) on the block. I do not know before hand how many columns the user selected table has!
This is what I have planned for this so far but I have some major questions before I can move on with this design:
1. I am going to create a table structure with fixed number of column in form (40 cols assuming that the custom table will not have more that 40 cols). (Kind of limitation but it's okay as of now).
2. Dynamically populate the block based on the table name selected by the user from LOV. Dynamically change the table column names based on the table selected etc.
3. Perform insert, update, delete using PL/SQL package.
So far it looks okay.
Now my real question is,
Can user still be able to user "Folders" functionality here? I have never done this kind of development before and I doubt the dynamic column naming, dynamic column data source will really work for "folders"!
Also, I am not really sure whether user will be able to save these "folder" queries?
Okay so form experts, can you ppl suggest me if this is really going to work? Are there any better ways to do this?
Initially I tried to do this in OA Framework but I got stuck at because as per OAF developer guide "I cannot user OAF personalization for dynamic items, regions etc".
For more info on that thread see this link...
Re: setUserCustomizable issue!
Thanks in advance for the help.

Any suggestion anyone?

Changing the Data source in Business Objects XI

Hi,
Is it possible to change the data source(not universe) in runtime to generate business objects reports. I am using BOXI 3.1.
Below is the code I am using to change the universe in runtime. I would like to change this so that i can change the data source instead of changing the universe. My intention is to generate report from multipple database using same universe. Right now I am using multipple universes connected to multiple datasources to achieve this. I am using Report Engine SDK(Java).
 if("Webi".equals(mDocKind))
 // Added for multiple database support
 DataProviders dataProvs = documentInstance.getDataProviders();
 try{
 //To support multiple queries in BO reports
 for(int count=0;count<dataProvs.getCount(); count++){
 DataProvider dp=dataProvs.getItem(count);
 DataSource ds= dp.getDataSource();
 infoUniverseObjects = getUniverseObject(infoStore,NewUniverseName);
 infoUniverseObject = (IInfoObject)infoUniverseObjects.get(0);
 String newDsCuid = infoUniverseObject.getCUID();
 dataProvs.changeDataSource(ds.getID(), "UnivCUID=" + newDsCuid, true);
 if(dataProvs.mustFillChangeDataSourceMapping())
 // Re-map data source to target Universe objects
 ChangeDataSourceMapping mapping = dataProvs.getChangeDataSourceMapping();
 ChangeDataSourceObjectMapping[] maps = mapping.getAllMappings();
 dataProvs.setChangeDataSourceMapping();
 }//for dataProvs.getCount()
 }catch(Exception e)
 mLogger.info("BOReportObject","createReport","Inside multiple data providers loop"+e.getMessage());
Thanks in advance

Hi Shameer,
I think this is only possible with the Universe Designer SDK (which is only available in COM).
Please kindly refer to the API reference for the Universe Designer SDK for more details:
http://help.sap.com/businessobject/product_guides/boexir31/en/bodessdk.chm
Also, please note that changing the universe connection when viewing a document on-demand is not recommended because this could lead to possible issues.
For example:
Two users trying to view documents that uses the same universe at approximately the same time.
But user A wants to use connection X and user B wants to use connection Y.
This could lead to an error while openning the document or while refreshing/retrieving the the data.
Hope this helps.
Regards,
Dan

I am new in oracle forms.I am using oracle forms 11g with weblogic 10.3.5 at windows 7.Through googaling I know how to create a database block,forms clause data block and stored procedure based datablock in oracle forms.I want to know that as in case of Database based datablock, could we commit form either on editing records or on insertion or deletion in data block.
I tried this but got error frm 40501.If we can perform editing and creation in such type of datablock then please tell me how.
Thank You,
regards
aaditya

When I base my datablock on a query using the "From Clause" property of the block query data source in the oracle Forms 6i,
I get the strange error
"ORA-00928: missing SELECT keyword"
The query I see in the Display Error in Help Menu is
SELECT DAY_NUMBER,CONSULTANT_ID,EVENT_ID,EVENT_NUMBER,SESSION_NUMBER,HOURS_UNPAID,HOURS_PAID,PAPERWORK FROM (EVENT_ASSIGNED_CONSULTANT) WHERE (CONSULTANT_ID=:1)
What should I do now?????? Please remove the brackets () from the table name.
Instead of (EVENT_ASSIGNED_CONSULTANT) use
EVENT_ASSIGNED_CONSULTANT

Frm-41380 error - cannot set the blocks query data source

Fairly new forms so bare with me. I am creating a form based on one table. This table has one column that is a nested table.
table name: szrtime
table columns: szrtime_code, szrtime_styp_list
szrtime_styp_list is a table of varchar2(1).
main block is szvtime_block
the block that contains the nested table is szvtime_styp_block
I read that I could use a WHEN_NEW_RECORD_INSTANCE trigger on the main block to display the related nested table. I have tried the folllowing:
Declare
select_stmt Varchar2(512) ;
Begin
If :szvtime_block.szvtime_code Is not null Then
     select_stmt := '(SELECT column_value FROM TABLE ( SELECT szrtime_styp_list FROM szrtime WHERE szrtime_code = ''' || :SZVTIME_BLOCK.SZVTIME_CODE || '''))';
     Go_Block('SZVTIME_STYP_BLOCK' );
     Clear_Block ;
     message('select_stmt = '||select_stmt);
Set_Block_Property( 'SZVTIME_STYP_BLOCK', QUERY_DATA_SOURCE_NAME, select_stmt ) ;
Execute_Query ;
Go_Block('SZVTIME_BLOCK') ;
Else
Go_Block('SZVTIME_STYP_BLOCK' );
Clear_Block ;
Go_Block('SZVTIME_BLOCK') ;
End if ;
End ;
The result is the frm-41380 error.
I have tried change the query data source type on the nested table block to Table or From-clause but did not help. The select statement that is valid and returns the correct result in Toad.
Any suggestions on what to look for? Thank you.

> But what is giving me pause is that the user will be updating, deleting, and inserting
into this table and, of course, the nested table column.
It would give me pause, too. I've never used nested tables, so I poked around in Forms on-line help. In Forms 6i, it specifically states that Forms does not support the Nested Table structure.
In Forms 10g help, it describes Nested Table structures, but says NOTHING about how a form would handle it. And that implies to me that it is still not supported. So good luck.
In addition to creating the view, you may need to provide your own nested table updating procedures via a package on the server which your form can call. I know Forms supports passing pl/sql tables ("indexed by binary_integer"), so you could pass your nested table back and forth between the package and the form in that format.

Query for records on a block with Query Data Source Type : Procedure

Hi All,
The veriosn of form I'm using is:
Forms [32 Bit] Version 6.0.8.23.2
I have a block based on a procedure.
But when I enetr-query and search for records specific to ceratin criteria even then the result of the Query is all records.
Is Query not allowed on a block with Query Data Source Type : Procedure.
Hope my question is clear.
Thanks in advance.

Arif

When you use a table based block, forms can construct any select with any where clause based on the given inputs. Using a procedure based block, forms cannot "know" which in or out parameter of the procedure corresponds to which item. Even if Forms could pass the value of an item to an argument automagically, the procedure would have to "do something" with the argument, and you´d have to code it.
So, any item that should be used in the where-clause must be mapped to an argument.
Perhaps it would be easier to use a table based block querying a view? For DDL, you could use an instead-of-trigger on the view.
