Data Block

Hi,As we all know data block is a combination of the sparse Dimension. IF i make a level 1 member of a sparse dimenison as a Dynamic Calc. Then i wanted to know how essbase will create a data block for that block. If if we perform calculation on it then will it work as usual as dynamic calc property results or will it be differ.

If a sparse member is dynamic - a block will not be created for it - even if you calculate that dimension.Regards,Jade-----------------------------Jade ColeSenior BI ConsultantClarity [email protected]

Data blocks in forms 6i, can not see the data

i have built an application in forms with some data blocks. the blocks a connect to some tables in the db. i have built them connectd as "system". but when i run the applicatio as user x i can do select, insert, update, delete, but i can not se the records in the datablocks (they are empty), but i can do all transactios. why?

First of all, developing from the System schema is not a good idea.
Who owns the tables your form is connecting to? The table owner should create a public synonym for each table name, and also needs to grant user x access to the table.

I can not put the data of a field(LONG RAW) consulted into a item of a data block

I want to query a field that is LONG RAW(it's a image) and put the data into a item of a data block (in Forms Builder), when i write ":BLOCK.FOTO:=vfoto" i recieve this errors: "bad bind variable ....". How can i put the data of field of my DB and put the data in a item of a data block(in Forms Builder)?.
I can store a image in a table of my DB, but i want to query a image stored in my DB and put it into anothers table, all this on FORMS BUILDER.

You have to base the image item on a base table and use EXECUTE_QUERY on that block. You can't do a direct select in PL/SQL into the item

Insert and update a data block which is based on view--urgent help required

Hi experts,
I created a view(A_VIEW) which is based on a union select. I have created a data block A_VIW_BLOCK which is based on this view. I need to insert/update one of the base tablesfor A_VIEW through this data block. I also need to be able to make a query through all the fields in the view.
The questions are:
1.Can it be done at all?
2. What properties need to be set?
3. If can't be done, what the best approach to achieve this?
Thanks in advance!!

Multiple data blocks on the same canvas

Forms newbie question:
Is it possible to have 2 data blocks with two different sets of transactional triggers (ON-UPDATE, ON-LOCK, etc.) on the same canvas?
I've got an example where i've got two data blocks (one sourced from a view, and one that is a CTL block) on the same canvas. The block sourced from the view is working fine. When I make updates, they are reflected, etc. But, i've got one field in the control block that I need to update from as well, and I can't seem to get it (or any of the CTL block items) to show up as "updateable", regardless of the set_item_property....theyre always grayed out.
Do i need to take the user to a new canvas to be able to utilize the update of the ctl field?

A second canvas is not needed. Normally, control-block items are always updateable, so there is something going on in your form to prevent it.
> I can't seem to get it (or any of the CTL block items) to show up as "updateable",
regardless of the set_item_property....theyre always grayed out.
What... Is there code someplace in the form that sets them to Enabled, false? If that is the case, then to get them working again, besides setting Enabled to true, you also must set Updateable and Navigable to Property_True. (This is documented at the end of the on-line help on Set_Item_Property.)

Hi,
You have two options
1. create a view and base the block on the view
2. create a block with a query Data Source Type of 'FROM clause query'

Multiple Selection from a data block

Hello,
I have a data block returning the names and surnames of employees. Can I select multiple rows from that data block?
Thank you

You could put a checkbox on the row and if it is ticked then interpret this as a selected row.
Sometimes it is useful to store this type of selection in some type of structure like a record group or index by table and process those rows rather than read the data block

Manipulating data from a ref cursor in the data block of a form

I am using Oracle Forms 10g. I have a ref cursor which returns columns A, B, C, D, E where B, C, D, E are values. The "Query Data Source Name" attribute in the datablock contains "CCTR_Extract_pkg.cctr_refcur". The "Column Name" attribute of item A contains "A", item B contains "B", etc. All of these columns are displayed on the form and it all works perfectly.
I have a new request, the users would like a 6th column displayed - column F - where it equals D - B.
Is there any way of doing this in the form only or do I need to change the ref cursor to accomodate the new column and then the form?
If it can be achieved in the Form (only) - then how do I reference the 2 columns?
Thanks in anticipation
Michael

Is there any way of doing this in the form only or do I need to change the ref cursor to accomodate the new column and then the form? The REF_CURSOR is the data source of your block so you will have to modify the CCTR_Extract_pkg package and cctr_refcur REF_CURSOR.
If it can be achieved in the Form (only) - then how do I reference the 2 columns?After you have modified your database package, I recommend you run the Data Block Wizard on your block and let Forms detect the 2 new columns. You can do this manually, but it is safer to let Forms do it for you. If you want to do it manually, open the Query Data Source Columns property and add your new columns.
Hope this helps,

Updating record in a data block based on view in oracle forms

hi all ,
We have two data blocks in our custom oracle form.The first data block is for search criteria provided with buttons 'GO' and 'ADD ROW' and the second data block is based on a view that fetches record when user clicks on GO based on the the criteria specified in the above block. The Below block contains one SAVE button too.
We have a requirement when GO button is pressed and corresponding records are shown in the below block, user should be able to edit the record. Want to know how to make it editable?
Help appreciated....!!!

Your view is based on how many tables and does it include all NOT NULL fields from all tables?

ORA-00607: Internal error occurred while making a change to a data block

Duh, and of course I missed the significance of
oracle 10 Xe in unix
XE is only supported for Linux - according to the downloads page that means "Debian, Mandriva, Novell, Red Hat and Ubuntu".
Oracle have not publically stated the reasons why XE is only available on Linux and Windows, but my guess is that it is something to do the Intel chip architecture. If this is so it would be possible for Oracle to port XE to run on Solaris for x86. But they have not done so yet.
Which means, alas, that you are unlikely to get any help for this one, because XE is not supported on any unix platform.
Good luck, APC

Unable to Drop table from a corrupted Data Block

while exporting tables i got message data block corrupted 7481. and while i was trying to drop the table, found SQL Recursive Error.
Pls Help me. i am on the way to recreate my database..
Thanks
Rinson

Is 7481 the block number?. Block corruption can be diagnosed using the CLI (Command Line Interface) dbv (database verify). You can also diagnose it by looking for the corresponding error message in the alert.log.
Trying to recover data from a corrupt block is only possible using rman. Otherwise, the only thing you can do is to mark the block as corrupt using DBMS_REPAIR, rebuild the table and try to rescue data by recapturing it.

How to query two data blocks simultaneously?

Dear all,
Need your inputs on the following problem statement...
Existing Functionality:
We have two data blocks A (Parent) and B (Child) in a relationship. Both data blocks refer to different tables.
Data block A is the query data block and for a single record in block A we can have multiple records in block B. Multiple records in block B are shown one at a time after executing a query, this is implemented by using a list item C (belongs to a third block).
For example
Let us say block B can have 5 different types of entries for each record in block A. In this case the list item C will have 5 values corresponding to these entries. Once the query is executed, block B will show the default entry for the queried record in block A. To see other entries for the record user can select the required value in list item C and corresponding entry in block B will be fetched.
Requirement:
Our requirement now is to enable querying upon both data blocks A and B simultaneously. To implement this I replaced data blocks A and B with a single data block X which is based on the join of the two tables referred by the Data blocks A and B earlier. As the fields should allow insert, update, delete operations we did not use a view here.
Issue:
Now the problem is, each record in block A for which block B had multiple entries earlier is now getting listed multiple times because of the join.
I have tried but could not find any solution for this. I would appreciate if any of you can suggest how we can query both blocks simultaneously without affecting the existing functionality.
Thanks,
Amit

I don't understand your requirement in detail. I try to repeat what i understood so far.
You have a master-block A based on a table A and a detail-block B based on a table B. So far so good. You can now query based on conditions just the datablock A, because B is a detail and therefore can only be queryied in context of block A.
Your reuirement is to query on both blocks A and B and find block in B also without giving conditions for the relevant block A.
Is it that ?
What i don't understand, what is block C used for?
An idea for the querying of block B's data: Create Non-database-items items in block A for the search-criteria you need on block B and make them Queryable.
In the PRE-QUERY-trigger on block A build a WHERE-condition if that search-criteria is entered, something like
IF :BLOCK_A.SEARCH_CRITERIA_FOR_BLOCK_B IS NOT NULL THEN
SET_BLOCK_PROPERTY('BLOCK_A', ONETIME_WHERE, 'WHERE PKVALUE IN (SELECT FKVALUE_TO_A FROM TABLE_B WHERE FIELDVALUE=' ||:BLOCK_A.SEARCH_CRITERIA_FOR_BLOCK_B)');
END IF;This would query also records to A for which you want to have the B-records. So you could keep block-structure up to master-detail.

How to count number of items present in a data block

hi all,
how to count how many items present in a particular data block in oracle forms 10g.
whether it is a text_item or display_item or list_item etc is there any method to do this.
please reply....

hi all,
i have written this when-button pressed but the problem is how to get the next item name in the block
DECLARE
     V_COUNT NUMBER:=0;
     V_FIRSTITEM VARCHAR2(100):='';
BEGIN
     GO_BLOCK('BLOCK_ITEMCOUNT');
     V_FIRSTITEM := GET_BLOCK_PROPERTY('BLOCK_ITEMCOUNT', FIRST_ITEM);
     LOOP
          V_COUNT := V_COUNT + 1;
          EXIT WHEN GET_ITEM_PROPERTY(V_FIRSTITEM, NEXTITEM) IS NULL;
          --V_FIRSTITEM := GET_BLOCK_PROPERTY('BLOCK_ITEMCOUNT', NEXTITEM);

Need advice on ORA-01578: ORACLE data block corrupted

We have a development database server version- 10.2.0.3 with materialized views refresh as complete every morning. Yesterday we had a power failure and the server went down and database was shutdown unexpectedly.
When we restarted the database after the server restarted, we found some of the datablocks got corrupted . Following were the exceptions that we saw in the alert.log.
Errors in file /i01_01/app/oracle/product/10.2.0/db_1/admin/orcl9/bdump/orcl9_smon_7547.trc:

OWNER
SEGMENT_NAME
SEGMENT_TYPE
VISH
INVENTORY_TXN
TABLE
where " INVENTORY_TXN " is a materialized view that was using the block that got corrupted. I can always recreate the MV by dropping and recreating it. Will it solve the problem???
If not, how can I recover/repair the block.???
Can anyone advice on this. Thanks very much in advance.

To recover a corrupted block,the best way out is to use Blockrecover command of RMAN. So you would need RmAN backup to perform the operation.But first ypu you need to ensure that this is a persistent error or not? Is this error is coming repeatedly or just once it happened?

What is the meaning of data blocks ?

hi,
What is the exact meaning of "data blocks" in the following paragraph ?
Index records and table records are organized in data blocks.
If you dispatch an SQL statement from an ABAP program to the database, the program searches for the data records requested either in the database table itself (full table scan) or by using an index (index unique scan or index range scan). If all fields requested are found in the index using an index scan, the table records do not need to be accessed.
A data block shows the level of detail in which data is written to the hard disk or read from the hard disk. Data blocks may contain multiple data records, but a single data record may be spread across several data blocks.
thanks

Hi ,
As Per oracle , data is stored in database in form of Data blocks , extent and Segments .
Physical space of memory is allocated to store data .
first level is called BLOCKS ,nexxt is extent and last is SEGMENT .
each block can store multiple data records and Conversly large no of data records can be stored in data Blocks .
data is stored in DATA BLOCKS which is smallest unit in oracle where data is stored in bytes .
regards
Deepak.
