Table activation problem after deleting ariw from table

Hi,
I have inserted a new field(xxxx) into custom table and activated it..
But ,when i tried to enter values for this new field in se16,this field doesnt exist there.But in se11 i was able to view..
So i deleted that field from tht table and inserted again,,
Now iam geting message that
xxxx field was deleted
Alter table is not possible..
Diagnosis shows that
The structure of the table changed at field level. This change requires a conversion of the table. This situation can occur for example if the data type or field length of the domain upon which the field is based was changed. A conversion is also generally necessary if the key of the table changed.
Procedure
Convert the table using the Database Utility (SE14).
Can you people let me know how i can cahge the table ..
Regards
parnith..

Hi Parnith,
Suppose you have entered a new field (or deleted a field) in your table in SE11(and table already contains data).
Now, your next step should be activating that table first.
For that :
1. Just click on save.
2. Goto Utilities -> Database Utility.
Click on that.
3. Click on Activate and Adjust database.
Now you will see your field added to your table.
Now you can simply Goto contents of the table and modify the records and fill the newly added field for each record.
Hope it helps.

Space reusage after deletion in compressed table

Hi,
Some sources tell, that free space after DELETE in compressed table is not reused.
For example, this http://www.trivadis.com/uploads/tx_cabagdownloadarea/table_compression2_0411EN.pdf
Is it true?
Unfortunatly I cannot reproduce it.

Unfortunatly the question is still open.
In Oracle 9i space, freed after DELETE in compressed block, was not reused in subsequent inserts.
Isn't it?
I saw many evidences from other people. One link I gave above.
But in Oracle 10g I see another figures. After delete rows in compressed blocks, and subsequent insert into that block, block defragmented!
Please, if who know any documentation about change in this behavior, please post links.
p.s.
in 10g:
1. CTAS compress. Block is full.
2. after, deleted every 4 from 5 rows.

Inserted rows were inserted in a several blocks. Total number of not empty blocks was not changed. Chains did not occure.

0x52:pri[23]     sfll=24
0x54:pri[24]     sfll=26As we see, that old rows were defragmented, and repacked, and moved to the bottom of block.
New rows (inserted after compressing of table) fill remaining space.
So, deleted space was reused.

Deleting records from table MVER

We are experiencing performance issues when adding data to table MVER. We have data on there that is over 5 years old which could be deleted. As we have not been able to find any standard program or process that carries out housekeeping on MVER we are considering writing an ABAP program to delete the records. Has anyone had any problems when deleting records from MVER or does anyone know of any reason why we should not delete these records in this way ?

Well, I wouldn't delet data from a standard SAP table based on information from the internete. I'd look at other alternatives.
Are you maintaining custom indexes on this table?
Are your database statistics up to date?
Consider a databse re-org.
I don't think simple inserts should cause a problem.

Open HUB ( SAP BW ) to SAP HANA through DB Connection data loading , Delete data from table option is not working Please help any one from this forum

Issue:
I have SAP BW system and SAP HANA System

Whenever I created any Open Hub as Destination like DB Table with the help of DB Connection, table will be created at HANA Schema level ( L_F50800_D )
Executed the Open Hub service without checking DELETING Data from table option
Data loaded with 16 Records from BW to HANA same
Second time again executed from BW to HANA now 32 records came ( it is going to append )
Executed the Open Hub service with checking DELETING Data from table option
Now am getting short Dump DBIF_RSQL_TABLE_KNOWN getting
If checking in SAP BW system tio SAP BW system it is working fine ..
will this option supports through DB Connection or not ?
Please follow the attachemnet along with this discussion and help me to resolve how ?

Santhosh Kumar

Hi Ramanjaneyulu ,
First of all thanks for the reply ,
Here the issue is At OH level ( Definition Level - DESTINATION TAB and FIELD DEFINITION )
in that there is check box i have selected already that is what my issue even though selected also
not performing the deletion from target level .
SAP BW - to SAP HANA via DBC connection
1. first time from BW suppose 16 records - Dtp Executed -loaded up to HANA - 16 same
2. second time again executed from BW - now hana side appaended means 16+16 = 32
3. so that i used to select the check box at OH level like Deleting data from table
4. Now excuted the DTP it throws an Short Dump - DBIF_RSQL_TABLE_KNOWN
Now please tell me how to resolve this ? will this option is applicable for HANA mean to say like , deleting data from table option ...
Thanks

Delete records from tableA which are not in tableB

Table A contains milions of records which is the best way to delete records from tableA which are not in tableB
delete from tableA where empno not in (select empno from tableb)
or
delete from tableA where empno not exists (select empno from tableb
where b.empno=a.empno)
any help

Hi
If you can do this, do with this:
create table tableC
as select a.*
from tableA a,
(select empno from tableA
minus
select empno from tableB) b
where a.empno = b.empno;
drop table tableA;
rename table tableC to tableA;

Problems with retrieving data from tables with 240 and more records

Hi,
I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
So for the retrievals that hang I have something like:
(3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
(3260008): FETCH NEXT:(DBI_FETCHNEXT)
and this is the last line,
while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
I will appreciate any comments/hints/help.
Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.
Thanks.

Table Problems after Word Export from RH8

I am running RoboHelp HTML 8 as part of Technical Communications Suite 2 on Windows XP Professional and exporting to Word 2007. This is a recent upgrade. Previously, I was just running RoboHelp 8 without TCS. All of the Adobe software is completely patched and up-to-date.
The help system I am converting to Word is large and results in over 600 pages of Word content with a lot of tables (generally just for data presentation and not layout purposes). I'm also using build tags and single-sourcing this document to another, shorter document that is over 400 pages long.
I have exported various documents from RoboHelp to Word many, many times before, and although I don't like the amount of reformatting I have to do, I'm used to the effort involved. However, the behavior seems to have changed recently.
These days (possibly after the conversion to TCS?), after I export the help system to Word, all tables are set to have the text wrap around them (Table Properties | Table | Text wrapping | Around). Before, this setting always defaulted to no wrapping. I wouldn't mind this, because I could simply set the tables to have no wrapping, but even after I do so, the full functionality of tables is still not available to me. For example, I can't set to header row to repeat across pages (Layout ribbon | Repeat Header Rows). I also can't set rows to not break across pages (Table Properties | Row | Allow to break across pages). In fact, I can't select a single row of the table generally without selecting the entire table. My coworker found out that you can copy each table into Word Pad and then copy it back into Word as a workaround, but that is extremely tedious. We already waste a lot of time reformatting these documents for various other reasons.
As a (probably irrelevant) footnote, I convert to .doc rather than .docx, because RoboHelp crashes when I export to .doc. I then save the .doc as a .docx file to conserve file size. The same problem exists in both file formats.
Thanks in advance for any help you can provide!

Hi, Peter. Thank you for your thoughtful response.
Yes, after exporting to Word, I couldn't set the tables' heading rows to repeat and couldn't select individual rows. Also, if I selected the entire table, normally Word would offer me the option to convert the table to text. However, Word seems to think that the table isn't a table, so instead it offers me the option to convert the text to a table. Good times. :-)
I write the above in the past tense, however, because I discovered a solution. I found a table in the Word output that didn't have the problem, possibly the only one of its kind in the project. In RoboHelp, I compared the HTML source of that table to a table that did have the problem. I discovered that the problematic table had two HTML tags that the unproblematic table did not: <?rh-align_start align="left" ?> and <?rh-align_end ?>. I deleted the tags and presto! The problem was fixed for this table in the Word output. This worked for a couple of other bad tables as well, so I decided to do a global find and replace. Using Find and replace in files in RoboHelp, I replaced each of these tags with nothing (i.e., a null value, essentially deleting them). Searching for the entire string didn't detect all instances, so I searched again for "rh-align" only and found about 50 instances, which I manually corrected in the HTML source.
So far, so good!
I didn't try the options you suggested, but I was suspecting a template problem as well. Thank God it wasn't because I wasn't relishing the prospect of tracking that down.
And yes! We tried your macros. Actually, the world-class tech writer Sue McKinney, who works with me, tried it, and she says it took three minutes to reformat the rows in the tables so they wouldn't break, which is a requirement of ours. We look forward to implementing the other table-related macro functionality you developed. Thanks for providing it for our use!

Problem when removing elements from table after apply sort

Hi,
I have big problem with <af:table> and sorting.
When I removed objects from a table without sorting, there is no problem but when I removed
items from the table after sorting, the remain items are not correct.
For example, i have in my table these items :
Item AA
Item CC
Item ZZ
Item BB
Item AA
Item BB
Item CC
Item ZZ
I sort the table and i select the following Items : Item BB a Item CC
The remains item is only Item AA, Item ZZ disappear.
If i resort the table, the missing Item zz appear again in the table.
Here is my jspx :
<af:table var="row" rowBandingInterval="1" width="1050" rows="5"
rowSelection="multiple"
value="#{pageFlowScope.editNotificationBackingBean.ingredients}"
binding="#{pageFlowScope.editNotificationBackingBean.ingredientsTable}"
autoHeightRows="10" id="t2">
<af:clientListener method="goEditRow" type="dblClick"/>
<af:serverListener type="doubleClickOnRow" method="#{pageFlowScope.editNotificationBackingBean.handleRequestIngredientsSelectBtn_action}"/>
<af:column headerText="#{bundle.col_fr_name}" width="240"
sortable="true" sortProperty="name.FR_Description" id="c1">
<af:outputText value="#{row.name.texts['fr'].value}" id="ot1"/>
</af:column>
In my backing bean i call this method to remove selected elements :
public void unselectBtn_action(ActionEvent actionEvent) {
RowKeySet rowKeySet = selectIngredientsTable.getSelectedRowKeys();
int i = 0;
Iterator it = rowKeySet.iterator();
while (it.hasNext()) {
Integer index = (Integer)it.next() - i;
selectIngredientsTable.setRowKey(index);
CompositionIngredient compositionIngredient =
(CompositionIngredient)selectIngredientsTable.getRowData();
notification.getProductDetail().getCompositionIngredients().remove(compositionIngredient);
i++;
selectIngredientsTable.getSelectedRowKeys().clear();
AdfFacesContext.getCurrentInstance().addPartialTarget(selectIngredientsTable);
Thanks in advance.

I have made a mistake, i don't paste the right <af:table> from my jspx.
Here is the correct one :
<af:table var="row" rowBandingInterval="1" width="1050"
rowSelection="multiple" id="tableSelectedIngredients"
value="#{pageFlowScope.editNotificationBackingBean.notification.productDetail.compositionIngredients}"
binding="#{pageFlowScope.editNotificationBackingBean.selectIngredientsTable}"
partialTriggers="::tab_ingredients_list_expressed_per">
<af:column sortable="true" headerText="#{bundle.col_name}" id="c5" width="180"
sortProperty="ingredient.name.FR_Description">
<af:outputText value="#{row.ingredient.name.texts['fr'].value}"
id="ot18"/>
</af:column>

Delete rows from table...Bizarre problem.

Folks
i HAVE this bizarre problem.
I hava a Java class which displays data read into a table with a delete
option by the side of each row.
Now lets assume you have 3 rows in the Table.
abc deleteButton
efg deleteButton
xyz deleteButton
When I click the first delete,that row gets deleted from the table.(perfect...)
Now I have 2 rows.
When I click on the first row,I get the error
'You clicked -1'
java.lang.ArrayIndexOutofBoundsException: -1 < 0.
Can anyone tell me why this is happening even though there are rows in the table.???
ActionListener al = new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("You clicked row : " + table.getSelectedRow());
javax.swing.table.TableModel model = table.getModel();
Object o = model.getValueAt(table.getSelectedRow(),0);
//System.out.print(model.getValueAt(table.getSelectedRow(), 0));
//System.out.println();
MyDeleteFunction(o.toString());
// Delete row from window.
((DefaultTableModel)table.getModel()).removeRow(table.getSelectedRow());
table.revalidate();
table.repaint();

Can not delete data from table which is queried in my stored procedure

Hi,
Anyone knows how to fix it:
I have a table. In a stored procedure, I have a simple query running on this table.
When I want to delete one record from that table, I got error message:
ORA-04091: table *** is mutating, trigger/function may not see it.
Thanks first.

Rick, the only time you should get a mutating table error is when a trigger is involved. FK problems have separate error codes (and would be a different problem than the one that started this thread). Using a DBA id check all the tables subject to DML by your function and by whatever calls your function for triggers. Only the owner or a DBA can see the existence of triggers on a non-owned table. This has caused some of the developers I work with to think tables that had triggers do not have them since they do not work under the owning or a DBA ID.
By your description of what you are trying to do in the function we do that all the time without problem.
How large is the function? How/When is it called?

Working in MUD: after deleting column whole table gets lost

Good morning community,
we do have a problem with the obiee admin tool.
we just migrated to version 11.1.1.6.6.
Now a colleague of mine worked with the MUD. He checked out the RPD-file and wanted to delete a column from a table within the presentation layer. Then he checked in this change again. He Uploaded the file to the server and everything is working fine.
Now the problem:
When he checked it out again, he saw that the full table was "deleted", but not only in the presentation layer, also in the business modell and the physical layer.
He opened the RPD file locally and there everything was okay.
Our first idea that the admin tool lost the link of these tables to the project couldn't be confirmed.
So we are asking you :-)
Maybe someone of you had this problem too and can explain how he solved it.
Thank you and have nice day,
Sven

Hi Sven,
Then he checked in this change again. He Uploaded the file to the server and everything is working fine.It should not be the case please confirm below
1. Uploaded means ? directly moved to MUD server instead of doing checking or from MUD to system where BI installed (NQSconfig.ini) ?
2. I'm sure he deleted the table instead of column (track it from MUD History in file option -->)
3. Link will break when (Tables in BMM & Physical ) a fact table is deleted so automatically associated dims will go off
4. Get the latest version . XXX (from MUD server) then change it to .rpd and deploy to get rid of issue
thanks,
Saichand

Oracle deleting rows from tables starting with the name PQ

hai friends
we are given access rights to delete only tables starting with PQ. HAVING PQ_NUM as primary key for all the PQ tables.
totally we have 6 tables. PQ_01,PQ_02, PQ_03,PQ_04,PQ_05,PQ_06.
ALL This tables will have one primary key. for example pq_01 willl have pq01_num as primarykey and pq_02 table will have pq02_num as primary
key.
pq01_num value will exist in all the primary key of pq tables.
i want query to delete rows from the pq tables based on the input value i give.
for example if i give primarykey value 122 then that value in pq tables should be deleted.
One more problem is there. pq_06 table does not have pq02_num column. here the column differs. it is pq06_num_req.
so give your idea of deleting the rows from pq tables

I dont have access to databse,this is untested
declare
v_cmd varchar2(2000);
columnname varchar2(30);
input_value number:=??;
tabowner varchar2(30):=???
begin
--step 1 identify table
FOR sub IN (SELECT table_name table_to_delete
FROM all_tables
WHERE table_name LIKE 'PQ%'
and owner=tabowner
) LOOP
----step 2 identify column
v_cmd :='select t.column_name from all_constraints S,All_Ind_Columns T where
S.OWNER=T.TABLE_OWNER
AND S.TABLE_NAME=T.TABLE_NAME
AND S.INDEX_NAME=T.INDEX_NAME
and s.owner=tabowner
AND S.TABLE_NAME='||table_to_delete||'
and s.constraint_type='''P'';
     execute immediate v_cmd into columnname;
     --step 3 delete records
    v_cmd := 'delete from '||tabowner||'.' ||
             sub.table_to_delete || '
   where '||columnname||'='||input_value;
     execute immediate v_cmd;
