Question regarding the execution of cursors and SQL statements

Hi,
I have cursor which fetches results from a table A.
Now, simultaneously, in other session, I ran an update on the table A and commited it.
1) My question is will the cursor keep fetching the old results or the cursor start fetching the new values when the data is committed?
2) I have a similar question in SQL too. We generally write SQL queries which take considerable amount of time- around half an hour. During this time, I ran an update on the table and committed it. Will the result set contain the old values ?
As per my knowledge, both should fetch the old values.
But, I would like to get my beliefs reinforced.
Thanks for your help.

Thanks John..
Your post drives me to ask another question. We've been getting the error "Snapshot Too Old" quite frequently.
So, we minimized the SQL and used cursor committing every 10000 records. This prevented the above error.
Is there any other possible reason why we get the error "Snapshot too Old"?
Thanks,
DonDon:
Typically, commiting more frequently increases the likelyhood of 1555, not decreases it. The 1555 error comes when the undo (or rollback in old terms) records that need to be read to support read consistency are no longer available. Simplistically, once a change has been committed, the undo records are marked as available for re-use and could be re-used thereby destroying the information that you need.
Even though ithe initial question is really old, read the Ask Tom thread posted by RPuttagunta. Tom explains it far better than I could, and the basic concepts have not changed.

Can the format of a SQL Statement modify the execution time of an SQL ....

Can the format of a SQL Statement modify the execution time of an SQL statement?
Thanks in advance

It depends on:
1) What oracle version are you using
2) What do you mean for "format"
For example: if you're on Oracle9i and changing format means changing the order of the tables in the FROM clause and you're using Rule Based Optimizer then the execution plan and the execution time can be very different...

Question regarding the "mcxquery" and "dscl -mcxread" commands:

Question regarding the mcxquery and dscl -mcxread commands:
Does anyone know why the mcxquery and the dscl . -mcxread commands don't show any info about MCX managed login items & printers? The System Profiler's "Managed Client" section does. Id like to see info regarding managed printers and managed login items using the mcx tools. I have Mac users running 10.5.2 with both login items and printers that are pushed out to them via MCX. The System Profiler app shows all of their policies, but the dscl . -mcxread and mcxquery tools dont. Why not?

How do you "call procedures/functions" without sql code? You need at least the call statement like
{call myProc(?,?,?)}that you wrap into a CallableStatement.
Other than that: when you switch off autocommit, you need to call commit/rollback at the end. Usually, if you don't commit/rollback a non-autocommitted connection, the transaction get's committed/rollbacked when you close the connection - that depends on the JDBC driver. But it's never a good idea to ommit the commit/rollback calls on a non-autocommit connection. Usually you enclose your code in a try/catch block like this:
con.setAutocommit(false);
try {
   con.commit();
} catch (Exception e) {
   con.rollback();
} finally {
    con.setAutocommit(true); //or:
    con.close();
}

I have 2 questions regarding the iphone 5. 1 How do i get my yahoo mail set up. I tried the setting it up as both a yahoo mail and other mail. 2. I seem to have lost my notes on my iphone 5 but I have them on my ipad. How can I use cloud to sync my notes?

I have 2 questions regarding the iphone 5. 1 How do i get my yahoo mail set up. I tried the setting it up as both a yahoo mail and other mail. 2. I seem to have lost my notes on my iphone 5 but I have them on my ipad. How can I use cloud to sync my notes?

I will address your second question.
First, make sure your iPhone and iPad have absolutely identical Apple IDs. If they do, use that Apple ID in Settings > iCloud on your iPhone to select the "Notes" option. Lo and behold, all your iCloud notes should appear on your iPhone.

I have just got my iPad2 and very pleased with it. I have a question regarding the monthly (recommended) battery full charge. Should I let the battery completely die down to nothing at all or would this be bad for my iPad?

I have just got my iPad2 and am very pleased with it. I have a question regarding the monthly (recommended) battery full charge. Should I let the battery completely die down to nothing at all before I plug in to recharge or would this complete drain be bad for my iPad?

It's not bad for it - on this page www.apple.com/batteries/ipad.html it says :
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

PL/SQL 101 : Cursors and SQL Projection

PL/SQL 101 : Cursors and SQL Projection
This is not a question, it's a forum article, in reponse to the number of questions we get regarding a "dynamic number of columns" or "rows to columns"
There are two integral parts to an SQL Select statement that relate to what data is selected. One is Projection and the other is Selection:-
Selection is the one that we always recognise and use as it forms the WHERE clause of the select statement, and hence selects which rows of data are queried.
The other, SQL Projection is the one that is less understood, and the one that this article will help to explain.
In short, SQL Projection is the collective name for the columns that are Selected and returned from a query.
So what? Big deal eh? Why do we need to know this?
The reason for knowing this is that many people are not aware of when SQL projection comes into play when you issue a select statement. So let's take a basic query...
First create some test data...
create table proj_test as
select 1 as id, 1 as rn, 'Fred' as nm from dual union all
select 1,2,'Bloggs' from dual union all
select 2,1,'Scott' from dual union all
select 2,2,'Smith' from dual union all
select 3,1,'Jim' from dual union all
select 3,2,'Jones' from dual
... and now query that data...
SQL> select * from proj_test;
         ID         RN NM
         1          1 Fred
         1          2 Bloggs
         2          1 Scott
         2          2 Smith
         3          1 Jim
         3          2 Jones
6 rows selected.
OK, so what is that query actually doing?
To know that we need to consider that all queries are cursors and all cursors are processed in a set manner, roughly speaking...
1. The cursor is opened
2. The query is parsed
3. The query is described to know the projection (what columns are going to be returned, names, datatypes etc.)
4. Bind variables are bound in
5. The query is executed to apply the selection and identify the data to be retrieved
6. A row of data is fetched
7. The data values from the columns within that row are extracted into the known projection
8. Step 6 and 7 are repeated until there is no more data or another condition ceases the fetching
9. The cursor is closed
The purpose of the projection being determined is so that the internal processing of the cursor can allocate memory etc. ready to fetch the data into. We won't get to see that memory allocation happening easily, but we can see the same query being executed in these steps if we do it programatically using the dbms_sql package...

So, what's really the point in knowing when SQL Projection occurs in a query?
Well, we get many questions asking "How do I convert rows to columns?" (otherwise known as a pivot) or questions like "How can I get the data back from a dynamic query with different columns?"
Let's look at a regular pivot. We would normally do something like...
SQL> select id
2        ,max(decode(rn,1,nm)) as nm_1
3        ,max(decode(rn,2,nm)) as nm_2
4 from proj_test
5 group by id
6 /
        ID NM_1   NM_2
         1 Fred   Bloggs
         2 Scott Smith
         3 Jim    Jones
(or, in 11g, use the new PIVOT statement)
but many of these questioners don't understand it when they say their issue is that, they have an unknown number of rows and don't know how many columns it will have, and they are told that you can't do that in a single SQL statement. e.g.
SQL> insert into proj_test (id, rn, nm) values (1,3,'Freddy');
1 row created.
SQL> select id
2        ,max(decode(rn,1,nm)) as nm_1
3        ,max(decode(rn,2,nm)) as nm_2
4 from proj_test
5 group by id
6 /
        ID NM_1   NM_2
         1 Fred   Bloggs
         2 Scott Smith
         3 Jim    Jones
... it's not giving us this 3rd entry as a new column and we can only get that by writing the expected columns into the query, but then what if more columns are added after that etc.
If we look back at the steps of a cursor we see again that the description and projection of what columns are returned by a query happens before any data is fetched back.
Because of this, it's not possible to have the query return back a number of columns that are based on the data itself, as no data has been fetched at the point the projection is required.
So, what is the answer to getting an unknown number of columns in the output?
1) The most obvious answer is, don't use SQL to try and pivot your data. Pivoting of data is more of a reporting requirement and most reporting tools include the ability to pivot data either as part of the initial report generation or on-the-fly at the users request. The main point about using the reporting tools is that they query the data first and then the pivoting is simply a case of manipulating the display of those results, which can be dynamically determined by the reporting tool based on what data there is.
2) The other answer is to write dynamic SQL. Because you're not going to know the number of columns, this isn't just a simple case of building up a SQL query as a string and passing it to the EXECUTE IMMEDIATE command within PL/SQL, because you won't have a suitable structure to read the results back into as those structures must have a known number of variables for each of the columns at design time, before the data is know. As such, inside PL/SQL code, you would have to use the DBMS_SQL package, just like in the code above that showed the workings of a cursor, as the columns there are referenced by position rather than name, and you have to deal with each column seperately. What you do with each column is up to you... store them in an array/collection, process them as you get them, or whatever. They key thing though with doing this is that, just like the reporting tools, you would need to process the data first to determine what your SQL projection is, before you execute the query to fetch the data in the format you want e.g.
create or replace procedure dyn_pivot is
v_sql varchar2(32767);
-- cursor to find out the maximum number of projected columns required
-- by looking at the data
cursor cur_proj_test is
    select distinct rn
    from   proj_test
    order by rn;
begin
v_sql := 'select id';
for i in cur_proj_test
loop
    -- dynamically add to the projection for the query
    v_sql := v_sql||',max(decode(rn,'||i.rn||',nm)) as nm_'||i.rn;
end loop;
v_sql := v_sql||' from proj_test group by id order by id';
dbms_output.put_line('Dynamic SQL Statement:-'||chr(10)||v_sql||chr(10)||chr(10));
-- call our DBMS_SQL procedure to process the query with it's dynamic projection
process_cursor(v_sql);
end;

Of course there are other methods, using dynamically generated scripts etc. (see Re: 4. How do I convert rows to columns?), but the above simply demonstrates that:-
a) having a dynamic projection requires two passes of the data; one to dynamically generate the query and another to actually query the data,
b) it is not a good idea in most cases as it requires code to handle the results dynamically rather than being able to simply query directly into a known structure or variables, and
c) a simple SQL statement cannot have a dynamic projection.
Most importantly, dynamic queries prevent validation of your queries at the time your code is compiled, so the compiler can't check that the column names are correct or the tables names, or that the actual syntax of the generated query is correct. This only happens at run-time, and depending upon the complexity of your dynamic query, some problems may only be experienced under certain conditions. In effect you are writing queries that are harder to validate and could potentially have bugs in them that would are not apparent until they get to a run time environment. Dynamic queries can also introduce the possibility of SQL injection (a potential security risk), especially if a user is supplying a string value into the query from an interface.
To summarise:-
The projection of an SQL statement must be known by the SQL engine before any data is fetched, so don't expect SQL to magically create columns on-the-fly based on the data it's retrieving back; and, if you find yourself thinking of using dynamic SQL to get around it, just take a step back and see if what you are trying to achieve may be better done elsewhere, such as in a reporting tool or the user interface.

excellent article. However there is one thing which is slightly erroneous. You don't need a type to be declared in the database to fetch the data, but you do need to declare a type;
here is one of my unit test scripts that does just that.

How to find out the execution time of a sql inside a function

Hi All,
I am writing one function. There is only one IN parameter. In that parameter, i will pass one SQL select statement. And I want the function to return the exact execution time of that SQL statement.
CREATE OR REPLACE FUNCTION function_name (p_sql IN VARCHAR2)
RETURN NUMBER
IS
exec_time NUMBER;
BEGIN
--Calculate the execution time for the incoming sql statement.
RETURN exec_time;
END function_name;
/

Please note that wrapping query in a "SELECT COUNT(*) FROM (<query>)" doesn't necessarily reflect the execution time of the stand-alone query because the optimizer is smart and might choose a completely different execution plan for that query.
A simple test case shows the potential difference of work performed by the database:

SQL>As you can see the number of blocks processed (consistent gets) is quite different. You need to actually fetch all records, e.g. using a PL/SQL block on the server to find out how long it takes to process the query, but that's not that easy if you want to have an arbitrary query string as input.

Question regarding the Transformation activity in BPEL

Hi,
I have a question regarding the Transformation activity in BPEL.
I have a database adapter that uses a PL/SQL API. The API returns two tables of nested objects and it automatically generates a schema for me based on the outputs structure. I need to use the Transformation activity to map both these out parameters to root element in the destination.
The element in the destination is "unbounded". Please take a look at the following screen shot -
http://www-apps.us.oracle.com:1100/~rvishnuv/transform1.gif
From the screen shot, you can notice that I have two XML segments X_TEST_TBL and X_TEST_TBL1 in the source and I have one GLOGXMLElement ("unbounded") in the destination. I need to map each of the source elements to the same destination. Then internally, I will be mapping the elements of X_TEST_TBL to "Location" segment/element and the elements of "X_TEST_TBL1" to "ItemMaster" segment/element. If I try to use "foreach" and map second
element "X_TEST_TBL1" also GLOGXMLElement using the foreach, I get the following error -
http://www-apps.us.oracle.com:1100/~rvishnuv/transform1_error.gif
Let us say my X_TEST_TBL contians two records and X_TEST_TBL1 contains one record. Is there any way that I can use these two out parameters to map to the same destination (GLOGXMLElement) so that my final document contains multiple "GLOGXMLElement"s that represents data from both the output parameters? i.e. there should be in total of three occurances of GLOGXMLelement in the output document such that two occurances correspond to data obtained from X_TEST_TBL and one corresponds to data from X_TEST_TBL1.
Please let me know if there is any way to achieve this.
Thanks
Ravi

I have read all the questions regarding the "Can't send photo using iMessage".

I have read all the questions regarding the "Can't send photo using iMessage". I followed everything and check everything that was in it. It's still the same. I am still not able to send a photo. It started happening last week. It was fine before that. There is no error message.
It will try to send but it will get stuck just before it sends
and the red ! will appear with the "Not Delivered" status.
When i tap on the !, it just says "This iMessage was not delived".
No other message or photo is sending as the same time as the photo.
I did reset it, I checked the email address, removed it as well. Turned it off then back on. Signed out and signed back in. Wi-Fi strength is very good. iOS is 6.0.1. I checked for updates, it is up-to-date I also checked a link http://support.apple.com/kb/TS2755. It did not help at all.
What's wrong?!?!?!?!

It is not a matter of reconsidering the decision. There are unsolveable technical problems with trying to run a program such as Firefox on Blackberry OS. We would need Blackberry to distribute a tool similar to Android's NDK to run on Blackberries.

Some simple questions regarding the Xcode.

I have some preliminary questions regarding the Xcode (objective C):
What is the difference between the programming files followed by .h and .m?
What does an asterisk * followed by a text mean (i.e. *window;)?
Is there any source that briefly explains the most common codes with examples (nsstring, nsarray, iboutlet, inaction.....etc)?
Any other tips will be highly appreciated.
Many thanks.

Xcode is the IDE.
Objective-C is the most common language used within Xcode.
UIWindow *window ..... the * means return the address of the instance variable 'window'.
An * is called a pointer to a variable.

Question regarding the pen tool (w/ picture inside)

Hello everyone! I have a question regarding the pen tool. I think this picture is very helpful for my question:
So in this pic is an orange rectangle and within that rectangle is a blue stripe. I would like the blue stripe to be perfectly flush (not over, and not under) the edge of the rectangle. For example, on the bottom end of the blue stripe, you can clearly see that the stripe does not extend far enough to the edge of the orange rectangle. At the top of the stripe, it goes a little bit over (a bit hard to see). I work with some complex shapes when using the pen tool and it is really slowing me down to compensate for over/under shapes. If it could just snap to the borders of other shapes it would make my life a lot easier. Thanks for reading and please help!

A couple of thoughts come to mind:
1. You could create the shape "face on", using guides, and the points will snap to guides with snap enabled. Then you could transform the whole thing together by selecting all the shape layers.
2. Holding down the shift key while dragging a point seems to cause it to snap to some things under some conditions. However, on having just tried to recreate what you're showing I didn't see the proper snap happening sometimes.
3. There's the full manual approach, of course where you zoom into thousands of percent and move the points by hand manually. I assume this is what you're trying to avoid.

Question regarding the installation of a J2EE 6.40 Add-in

Hi all,
I would like to install a J2EE engine on a test instance of ECC 5.0 and have a few questions regarding the installation...
Do I have to use the MASTER CD to first install the J2EE engine (Support Package 0) and then apply the latest support packages found on the SAP Marketplace?
Or should be able to directly install the J2EE Add-In by using the latest support packages found on the SAP Marketplace?
Best regards,
Xavier Vermaut

Thanks Bhavik for your reply,
That's what I actually thought but I get the following problem... Here's what I wrote into my customer message... I am still waiting for an answer and would like to get this solved ASAP
Dear SAP,
We would like to install the J2EE 6.40 Add-In on our ECC 5.0 instance
(TST) but get the following error message at the very beginning of the
installation
> Cannot find an installed ABAP system, which is a prerequisite for a
> J2EE Add-In installation. The installation cannot continue.
We checked the installation logs (sapinst_dev.log) and found the
following :
> Found these instances:
> sid: MGR, number: 00, name: DVEBMGS00, host: erpqs1a
> sid: TST, number: 10, name: DVEBMGS10, host: erpqs1a
Why does the installation say that it can not find any ABAP systems when
having previously found the 2 different instances running on this
server?
Would this problem be related to the fact that we have two instances on
this server?
Please find hereunder the way we performed this installation :
01) Download of the 4 different parts of SAP J2EE Engine 6.40 SP 10
     (Solaris 10 - Oracle)
     Part I   : SAPINST10_0-20000121.SAR         (Solaris 64)
     Part II : CTRLORA10_0-20000121.SAR         (Solaris 64)
     Part III : J2EERTOS10_0-20000121.SAR        (Solaris 64)
     Part IV : J2EERT10_0-10001982.SAR          (OS Independant)
02) Extract these 4 archives into /install/J2EE_640
03) Check Java Version and Environment Variables
04) Check Solaris Pre-Requisites
05) Adapt "product.xml" as specified in OSS Note 697535 (IGS)
06) Log in as 'root'
07) Set DISPLAY environment Variable
08) Move to the Installation directory
      ( /install/J2EE_640/SAPINST-CD/SAPINST/UNIX/SUNOS_64 )
09) ./sapinst
10) In the 'Welcome to Netweaver Installation' screen, select
      => Dialog Instance Finalization
Any idea how to get this solved?
Best regards,

Questions regarding the APEX sample shopping cart

I am fairly new to APEX development, but had a few questions regarding the sample APEX shopping cart:
1) is there a way to integrate Google check out payments with the sample APEX shopping cart
2) is there any way to list a service, that involves monthly recurring payments
3) is there any other shopping cart that is APEX based that is available
Thank you,
Ashok

Hi Sam,
i am haveing a deadline monitoring for my shopping cart where remainders are going to generate for first day and the second day, after both the remainders generated and the approver changing the cost center or asset or order at that time, the workflow flow should retrigger and send the approval mail to the new approver, but it is not going to the new approver, so the workflow is not triggering in my case. so i need to restart my workflow again if any changes occurs.
in the second point my functional guy says that, when the approver changes any text or any date like that it should come for the accept changes, and when he sees the approval preview, only the approval person should be there but not the creator person in the preview and when the creator of the sc accepts the changes it is showing that it is approved by the creator name but he says that it should the approver name not the creator name.
so can you please help me in this to get the solution.
thanks in advance
