Excess Parsing on PAVERSION table: How to tweak?

Hi
Following SQL on PSVERSION table is getting parsed around 14k times (around 15% of the total). Is there something I need to check and tweak to improve the overall performance?
SELECT VERSION FROM PSVERSION WHERE OBJECTTYPENAME = 'SYS'
Any clue about this is most welkom.
Regards
Vishal

This query is running on every call of Peoplesoft object to define if the caching version is the good one or not.
This query should not be a performance issue root cause, ensure you have the index and statistics up-to-date as well.

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Alter a BAPI Result Table, how to get into the display "loop" ?

Hello all,
i have a problem regarding the result rows of a RFC/BAPI Call.
There are three views, let's say 1,2,3. In View 1, i call a BAPI, and display the results in a table in View 2. I added a button in each row, which calls View 3 and displays some details concerning the selected row.
I now want to store a flag for each row, that has been displayed in this way.
In View 3 i store the key value of the displayed row in an own value node in the context.
When i go back from View 3 to View 2, i want to see that flag (in an extra column) in every row, that has been selected in this session.
So i do not know, how to alter a single row in the BAPI result table, how to get into the "loop" that is used by WD to display the table.
already tried a supply function, but i was not able to alter single rows.
Any suggestions/tips or perhaps code fragments of working supply functions ?
Thank you !

Hello,
I'm not sure whether I understood your problem correctly, but I will try to give an answer.
The easiest way I see is to copy the RFC Results to a Component Controller Context structure with an additional Flag field. You can use WDCopyService for copying.
Then on the event of selecting you set your flag as appropriate for you (e.g. if you want to use an image as flag you set the Image path) on the current element of your table. Then display View 3.
On going back View 2 should show now the new flag values...
The trick is to copy the values (as at Time structures can not be expandend with new fields) and set the Flag on the onSelect event.
Hope this helps,
Frank

From a table how do u find whether a material is used in another material B

hi,
From a table how do u find whether a material is used in another material BOM
thanks in advance

Yes as Velu mentioned you can get the details from STPO.
Note that you have to use field IDNRK in table STPO to check if the material is used as a BOM Component.

After creating a table, how do I type outside of it? I can't get a cursor to come up.

After creating a table, how do I type outside of it? I can't get a cursor to come up.

Barker,
If by "outside" you mean "on the right or left of" a table, you must make the Table a Floating Object to do that.
If you must use Inline Tables, you can do this:
Add a Floating Text Box with the text that needs to be "outside" the table. Arrange, then Group the Text Box with the Floating Table, and then set the Group to Inline.

More than one root table ,how to design cache group ?

hi,
each cache group have onle one root table , many child table ,if my relational model is :
A(id number,name ....,primary key id)
B(id number,.....,primary key id)
A_B_rel (aid number,bid number,foreign key aid referenc a (id),
foreign key bid referenc b(id))
my select statement is "select ... from a,b,a_b_rel where ...."，
i want to cache these three table , how should i create cache group ?
my design is three awt , Cache group A for A , Cache Group b for b, Cache group ab to a_b_rel ?
are there other better solution ?

As you have discovered, you cannot put all three of these tables into one cache group. For READONLY cache groups the solution is simple, put two of the tables (say A and A_B) in one cache group and the other table (B) in a different cache group and make sure that both use the same AUTOREFRESH interval.
For your case, using AWT cache groups, the situation is a bit mnore complicated. You must cache the tables as two different cache groups as mentioned above, but you cannot define a foreign key relationship in TimesTen between tables in different cache groups. Hence you will need to add logic to your application to check and enforce the 'missing' foreignb key relationship (B + A_B in this example) to ensure that you do not inadvertently insert data that would violate the FK relationship defined in Oracle. Otherwise you could insert invalid data in TimesTen and this would then fail to propagate to Oracle.

My iPad 3 "Brain/Table" (How it is called in my language) Burnt. Can it be repaired ?

My iPad 3 "Brain/Table" (How it is called in my language) Burnt. Can it be repaired ? and I need to know the English name of that "Brain" and I need to know the English name of that "Brain"
By the way, last time when I tried to turn it on, it charged, showed the Apple logo and than turned off, no lock screen and nothing.
Than I gave it to repair and they said brain is burnt..

I don't know what the Brain is but I imagine that the repair center said that the processor was bad. If they couldn't repair it, then there is nothing that you can do with it. Apple doesn't repair iPads, they replace them. If you are out of warranty they do offer replacement iPads starting at $250.00 in the U.S. you can check and see what the policy is where you live.

Master Child tables how to get the latest rows from both

Hi,
Need some help with the sql. I have two tables Master & Child. In my Master table I have multiple rows for the same record and in the child table also multiple rows for the same master row how can I get the latest one's from both.
For example Data in my Master table looks like
CONT_ID                  SEQ_NUM        DESCRIPTION
1                         189             Update 2
1                         188             Update 1
1                         187              NewNow in the child table for the same CONT_ID I may have the following rows
CONT_ID                   UPDATED_DATE                                     STATUS
1                        3/16/2010 2:19:01.552700 PM                          P
1                        3/16/2010 12:29:01.552700 PM                         A
1                        3/16/2010 12:29:01.552700 PM                         P
1                        3/16/2010 12:19:01.552700 PM                         NIn my final query how can I get the row with seq_num 189 as it's the latest in Master table and from child table the row with status of P as it's the latest one based on the time. Here is the query i have but it returns the latest row from the child table only and basically repeats the master table rows as opposed to one row that is latest from both:
Thanks

Hi,
You can use the analytic ROW_NUMKBER function to find the latest row for each cont_id in each table:
WITH     got_m_rnum     AS
     SELECT     cont_id,     seq_num,     description
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         seq_num     DESC
                       ) AS m_rnum
     FROM    master_table
--     WHERE     ...     -- any filtering goes here
,     got_c_rnum     AS
     SELECT     cont_id, updated_date,     status
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         updated_date     DESC
                       ) AS c_rnum
     FROM    child_table
--     WHERE     ...     -- any filtering goes here
SELECT     m.cont_id,     m.seq_num,     m.description
,     c.updated_date,     c.status
FROM     got_m_rnum     m
JOIN     got_c_rnum     c     ON     m.cont_id     = c.cont_id
                    AND     m.m_rnum     = c.c_rnum
                    AND     m.m_rnum     = 1
;If you'd like to post CREATE TABLE and INSERT statements for the sample data, then I could test this.
If there happens to be a tie for the latest row (say, there are only two rows in the child_table with a certain cont_id, and both have exactly the same updated_date), then this query will arbitrarily choose one of them as the latest.

External table.How to load numbers (decimal and scientific notation format)

Hi all, I need to load inside an external table records that contain 7 fields. The last field is called AMOUNT and it's represented in some records with the decimal format, in others records with the scientific notation format as, for example, below:
CY001_STATU;2009;Jan;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Jan;11200100;'60800;CYZ900;41380,77
The External table's script is the following:
CREATE TABLE HYP_DATA
COUNTRY VARCHAR2(50 BYTE),
YEAR VARCHAR2(20 BYTE),
PERIOD VARCHAR2(20 BYTE),
ACCOUNT VARCHAR2(50 BYTE),
DEPT VARCHAR2(20 BYTE),
ACTIVITY_LOC VARCHAR2(20 BYTE),
AMOUNT VARCHAR2(50 BYTE)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
DEFAULT DIRECTORY HYP_DATA_DIR
ACCESS PARAMETERS
( RECORDS DELIMITED BY NEWLINE
BADFILE 'HYP_BAD_DIR':'HYP_LOAD.bad'
DISCARDFILE 'HYP_DISCARD_DIR':'HYP_LOAD.dsc'
LOGFILE 'HYP_LOG_DIR':'HYP_LOAD.log'
SKIP 0
FIELDS TERMINATED BY ";"
MISSING FIELD VALUES ARE NULL
REJECT ROWS WITH ALL NULL FIELDS
"COUNTRY" Char,
"YEAR" Char,
"PERIOD" Char,
"ACCOUNT" Char,
"DEPT" Char,
"ACTIVITY_LOC" Char,
"AMOUNT" Char
LOCATION (HYP_DATA_DIR:'Total.txt')
REJECT LIMIT UNLIMITED
NOPARALLEL
NOMONITORING;
If, for the field AMOUNT I use the datatype VARCHAR (as above), the table is loaded but I have some records rejected, and all these records contain the last field AMOUNT with the scientific notation as:
CY001_STATU;2009;Jan;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Feb;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Mar;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Dec;11220020GR;'03900;CYZ900;-9,99999999839929e-03
All the others records with a decimal AMOUNT are loaded correctly.
So, my problem is that I NEED to load all the records (with the decimal and the scientific notation format) together (without records rejected), but I don't know which datatype I have to use for the AMOUNT field....
Anybody has any idea ???
Any help would be appreciated
Thanks in advance
Alex

Select and ... only one time in table - how?

Hallo,
in SRList from SRDemo "Select and View / Edit" comes only on top of the table.
In my page it comes on top and bottom of the table. why is it so and how i can customize it?
i don't see the point.

There isn't much point when you only have 10 items in the table, but imagine the case where there are 100 or more rows in the table (possibly after the user has selected to view all rows). Then it would be conveniant to have the selection facet at the bottom of the table too, so that the user doesn't need to scroll all the way back up to the top.
As for customisation, I don't think that you can change the behaviour in that way.

TABLE - How to set the row in the table

I have a problem where I have a selection on one view and then call a second view to display the results in a table. The table displays 5 rows. I then go down to the 20th row and select the row. When I have finished processing, I still have row 20 selected and I go back via a plug to the selection screen. I then enter new criteria and go back to the second view and the table displays that data showing row 20 as the first row. How do I get it to go back to row 1 every time I go into the second view??

Hello Graeme,
assuming i understand the problem, as a quick solution it would perhaps help to set the lifetime of the second view from "framework controlled" to "when visible" (in the properties of the view). Another way could be to explictly invalidate the context node holding the data for the second view after having left the view.
Kind regards

How to fix a faulty partition table, How to fix a faulty partition table

I have a 400gb partition on my 500gb HD, the remaining 100gb was split up in 3 partitions. I deleted 2 of these partitions, restarted and now Disk Utility claims my 400gb drive is now 53gb, accessing files has become impossible.
I can still see all the files listed but am unable to open them or copy them, I get a -36 error.
I have thrown Disk Utility, DiskWarrior, TechTool Pro and some lesser known tools at it but none of them wants to repair the volume.
Sounds to me like a busted partition table, after all that was all that was altered, in theory I should be able to access my files. Does anyone have any suggestions on how to fix this?

Problem solved, I used iPartition to resize the partition back to its original size after which I could copy all data off.

ADF table: How to find out which rows were modified by the user

Hi,
I am using ADF table to display data that can be modified by the user (ReadOnly = false in the input text). I need to find out which rows were modified by the user, and only update (persist) those rows in the database.
Is there an easy way to find out which rows were modified by the user.
I am NOT particularly concerned with which columns were modified as I would update the entire row (if any data in that row is modified).
I am using Oracle JDeveloper version 11.1.1.3.
Thanks,
Ash K

Thanks Timo.
I am using ADF Data Control (which are created from Web Service proxy) to display/update the data.
In the backing bean, the operation that is invoked at the time persisting data is as follows:
public void commitOperation {
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("operationA");
DCIteratorBinding dciter = (DCIteratorBinding)bindings.get("someIterator");
for(int i=0; i<dciter.getViewObject().getEstimatedRowCount(); i++)
Row row=dciter.getRowAtRangeIndex(i);
SomeObject someObject= new SomeObject ();
someObject.setAttr1(row.getAttribute("Attrbute1").toString());
someObject.setAttr2(row.getAttribute("Attribute2").toString());
objectList.add(someObject);
operationBinding.getParamsMap().put("param1", objectList);
ResultObject result = (ResultObject) operationBinding.execute();
Inside the for loop (or any other place in the backing bean), I would like to figure out if the row was modified by the user. Please let me know if how to get that. If ADF provides this automatically, that would be GREAT.
Thanks,
Ash K

Moving data between tables (how to find out if the 2nd table is empty)

Hi,
I have 2 tables, and I'm copying records from one table to another.
I've followed the Wiki: [https://www.sdn.sap.com/irj/sdn/wiki?path=/display/vc/movingdatabetween+tables]
So far, everything works ok.
Here is my question: how do I get the number of records passed?
I mean, how do I know the number of rows in the 2nd table? (Remember that this number is variable, because it depends on how many rows I've inserted and deleted on the 2nd table).
I've tried to achieve that using a data store with a numeric field, but I couldn't find the way to increment/decrement the numeric field on data store, and insert/delete the row on table at the same time .
All I want is to find out if the 2nd table is empty or not.
Any ideas to solve this?
Thanks in advance!
Help will be point-rewarded.
Marcelo

Hi Ahmed
thanks for your reply, it was very helpful!! (I've assigned points to you)
However the user can add twice or more times the same row... so the counter doesn't reflect the real number of rows in the 2nd table.
I've partially solved this also using a data store with a parameter called key_list, where I add (I mean, concatenate) the key field for the selected row.
So, if I have a table with 4 rows with key fields "key1", "key2", "key3", the parameter key_list would get "key1;key2;key3".
So far, it's ok. But when I remove a row previosly added.... I can't remove the key from the key_list parameter. (I mean, from 2nd table I choose to remove the "key2" row, but I don't know how also remove the key name from the key_list)
I hope be clearly enough.
Any help will be really appreciated and point-rewarded.
Thanks again.
Best Regards
PS: is there any way of "mark" a row that has been added to the 2nd table? I mean, using (for example) a hidden boolean field named "added", that becomes true when the selected row is added to the 2nd table.

Error log table how to track the run details

Hi ,
I am using the log errors concept in oracle and recording the errors.
My table is employees and I used the
be low script to create the error log tables.
BEGIN
DBMS_ERRLOG.create_error_log (dml_table_name => 'employees');
END;
It has created a table called err$_employees;
I have run the procedure and the procedure has inserted some records into the table for unique constraint error .
but when i rerun the same job , again it has inserted the same records whcih has created a proble now .
How will i figure out that which records are from the first runa dn which are from the second run?
Also i want to fail my job based on entried in the error log table i created.
Is it possible to track whats records belong to what instance in error log table.
hope i am clear abt the requirement i'm looking for ?
thanks
sri

If you look at the documentation you will see you can tag records that are inserted in the error log table e.g.
insert into employees
select ...
from ...
where ...
log errors into err$_employees('My Run Identifier')
You need to construct the string used as a tag so you can identify your individual runs.
