How to create a one-column collection from another multi-column collection?

Hi,
I am describing a SQL statement to get it's column list:DECLARE
cur NUMBER;
col_cnt INTEGER;
rec_tab DBMS_SQL.DESC_TAB;
type my_colls_t is table of varchar2(30);
my_colls my_colls_t;
BEGIN
cur := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(cur, 'SELECT * FROM my_view' , DBMS_SQL.NATIVE);
DBMS_SQL.DESCRIBE_COLUMNS(cur, col_cnt, rec_tab);
END;Now I need to get out the columns list from rec_tab.col_name and put it to my_colls collection. Have Oracle any build-in to do that? If not, what is the best way to do this?
Thanks in advance,
JackK

JackKYou can't do something like
my_cols := rec_tab.column_name;You need to loop throught the collection and assign each element. Like this.
for i in 1.. rec_tbl.count
loop
my_cols(i) := rec_tbl(i).column_name;
end loop;

I would like to know how can I modify one column of current and next record depending of some criteria using SQL2012?
The criteria is:
Type should always flow F->T
if current abs(amount)> next abs(amount) then groupid = 'PD'
if current abs(amount)< next abs(amount) then groupid = 'PI'
there is no case when those amounts will be equals
where current(custid) = next(custid) and current(service) = next(service) and groupid is null
Any help will be really apreciated.
Thank you

I tried that and got this error
'LAG' is not a recognized built-in function name.
You said you were using SQL 2012, but apparently you are not. The LAG function was added in SQL 2012. This solution works on SQL 2005 and SQL 2008:
; WITH numbering AS (
   SELECT groupid,
rowno = row_number() OVER (PARTITION BY custid, service ORDER BY date, id)
   FROM   #ServiceChange
), CTE AS (
   SELECT a.groupid,
CASE WHEN abs(a.amount) < abs(b.amount) THEN 'PD'
   WHEN abs(a.amount) > abs(b.amount) THEN 'PI'
END AS newgroupid
   FROM numbering a
   JOIN numbering b ON b.custid = a.custid
AND b.service = a.service
AND b.rowno   = a.rowno - 1
UPDATE CTE
SET   groupid = newgroupid

How can I separate one column into multiple column?

0001 CURRENCY USD
0002 PHONE_NUMBER 555-555-0002

BUYER_ID PHONE_NUMBER EMAIL CURRENCY
0001 555-555-0001 [email protected] USD
0002 555-555-0002 [email protected] USD
0003 555-555-0003 [email protected] CAD
Any help would be greatly appreciated.

This is another solution. Suppose your actual table's name is test(which has the redundant data). create a table like this:
CREATE TABLE test2 (BUYER_ID number(10),PHONE_NUMBER varchar2(50),EMAIL varchar2(50),CURRENCY varchar2(50));
then you will type this procedure:
declare
phone_number_v varchar2(50);
EMAIL_v varchar2(50);
CURRENCY_v varchar2(50);
cursor my_test is select * from test;
begin
for my_test_curs in my_test loop
select ATTRIBUTE_VALUE INTO phone_number_v from test
where person_id=my_test_curs.person_id
and attribute_name ='PHONE_NUMBER';
select ATTRIBUTE_VALUE INTO EMAIL_v from test
where person_id=my_test_curs.person_id
and attribute_name ='EMAIL';
select ATTRIBUTE_VALUE INTO CURRENCY_v from test
where person_id=my_test_curs.person_id
and attribute_name ='CURRENCY';
INSERT INTO test2
VALUES (my_test_curs.person_id,phone_number_v,EMAIL_v,CURRENCY_v);
END LOOP;
END;
Then you will create your final table like this:
create table final_table as select * from test2 where 1=2;
After that write this code:
INSERT ALL
into final_table
SELECT DISTINCT(BUYER_ID),PHONE_NUMBER,EMAIL,CURRENCY
FROM TEST2;
If you have a huge amount of data in your original table this solution may take a long time to do what you need.

How to create automatic creation of BP from customer and vendor master data

Hi gurus,
can any one tell how to create automatic creation of BP from customer and vendor master data.
Please give me the steps.
Thanks
Sasikanth.

HI,
Goto SPRO\ Cross application components \ Master data synchronization \ Synchronization control.
Assign account groups of customer and vendors to respective BP grouping. This setting is enough to create BP in background while creating customer / vendor. But the fields groups are very much important, ensure mandatory fields should be sync.

Pages: How can I sort one column of words and not have it affect the other columns?

How can I sort one column of words and not have it affect the other columns? I have opened the inspector to the edit columns and rows under Table. It will sort the column, but then it changes the other colums as well. I know that if I use Numbers, it will work, but I want to know how to do the same thing in Pages.

Hi Peter,
Numbers sorts full rows on values in selected column(s). The technique for sorting a single column is essentially the same as Jerry is describing for Pages tables—separate the (data in the) column to be sorted, sort it, return it to the table.
In Numbers the actual column may be separated from the original table, sorted, then returned. In Pages, the data must be extracted, sorted, then pasted back in, overwriting the unsorted data (if it was left in the original table).
iWork tables follow a database model in which each row is a Record, and each column holds a Field within the records.
As evidenced by the current question (and several similar questions arising in the Numbers community) that model doesn't apply to the way some users, especially some who come in from the MS Excel world, use tables.
With Excels model—islands of data on a single large table, the ability to sort one or a selected few columns of data makes sense. One 'island' may comprise only cells AA21:AH50. Sorting that small 'table' should be possible without disturbing the rest of rows 21-30, which are probably part of one or more other 'data islands' in the sea that is a MS Excel spreadsheet.
In Numbers, each of those 'islands' would be a separate Table, and that Table would be sortable without disturbing other Tables in the document.

How to embed and launch ipa file from another ipa package created using Air for iOS

Hi Guys,
Anybody out there knowing how to embed and launch ipa file from another ipa package created using Air for iOS ?

Tracy,
Thanks. That worked. However I have another related question:
I convert the xml feed to a XMLListCollection by doing:
<mx:XMLListCollection id="mission"
source="{xmlFeed.lastResult.day}"/>
and
<mx:XMLListCollection id="mission1"
source="{xmlFeed.lastResult.day.tBlock}"/>
On the chart I have
<mx:ColumnChart id="missionReadiness" height="150%"
width="100%"
paddingLeft="2" paddingRight="2"
showDataTips="true" dataProvider="{mission1}">
<mx:series>
<mx:ColumnSeries xField="" yField="@today"
displayName="Today"/>
<mx:ColumnSeries xField="" yField="@tomorrow"
displayName="Tomorrow"/>
<mx:ColumnSeries xField="" yField="@afterT"
displayName="After Tomorrow"/>
</mx:series>
</mx:ColumnChart>
the yField works, but for the xField I want to have the @date
but refers to the parent node, so I am clueless on how to refer to
it.
Also, I would like to display on the chart only the values to
a specific date (like @date="05/17/2007").
Any suggestions on how to do that?

How we can remove one authorization object from multiplt roles

How we can remove one authorization object from multiplt roles

> Correct me if I am wrong !!
O.K., Here I go
> But if the object is maintained in SU24 and if you use Expert mode for generation of the role then again those objects may be pulled.(make sure you never use expert mode once you delete the objects)
Actually using expert mode and choosing 'edit old status' is the only way to avoid objects being 'pulled in' after menu changes.
> As jurjen said, you may download the tables and instead of deleting the object from the excel sheet, change the value of the object in column "DELETED" = X, by doing this only the objects get inactivated(but remain in PFCG).
I am not speaking of downloading tables but about downloading roles from PFCG. This will not get you a spreadsheet but a flat textfile. If you whish to set the object status to deleted you'll have to swap the space on position 207, right behind the 'U, S, G' flag, with an 'X' for all corresponding lines.

How to create a One Page checkout

Hello nice people,
Does anybody knows how to create a ONE-PAGE Check Out Process in Online Shop Layout?
Thanks in advance

"I can resolve the problem if I can insert one page (or step) after
"registration - buy". This would be a "summary" page where the customer has
the last opportunity tu check out all his data and, if it is needed, to
correct his order, billing address, shipping, the way of payment"
<<< The only way to do this is with JS. You can use jQuery's .load() method
to load your cart into the registration layout. You'll have to do some
parsing of that cart table to obtain things like product name, quantity etc
and present this in some kind of summary. Parsing tables in jQuery is not a
nice task, so if you're going to embark onto producing this kind of summary
you may want to get rid off the table from the cart and simple throw in
some divs and tags which will help you parse the cart nicely. That mans
you'll have to construct the layout for the cart though using JS.
Example of alternative cart layout:
It renders like this:
product one
(S)
product one
(M)
onchange="UpdateItemQuantity(this.value,231502,234492,6737768,183427,'','US');return
false;" class="cartInputText" type="text" value="1">
onchange="UpdateItemQuantity(this.value,231502,234492,6737768,183428,'','US');return
false;" class="cartInputText" type="text" value="3">
$10.00
$45.00
$55.00
You can see that this is much nicer to read and you can then construct your
own data structure that will hold this info and render it it whichever way
you want to. You can even write it back as a table where each product is in
its own row. You may want to look at something that gives you template.
model, controller like ember.js.
Anyway, I hope that helps somewhat.
Cheers,
M

If I have multiple email accounts, how can I prevent one of them from sending email?

If set up multiple email accounts in Thunderbird, how can I prevent one of them from sending email, while allowing others to send?

Simple answer:
do not use the email address when sending or replying or forwarding emails. Sending is not automatic, you have to generate the email and click on a Send button.
You could use an smtp server that will not allow sending using the incorrect server for the email address, so that it cannot send, but if you accidentally use the email address you may get an error message, but at least the email will not be sent. Do this here:
Tools > Account Settings for the mail account.
bottom right Outgoing Server - select one that will not accept sending using wrong email address
OR
in Outgoing Server(SMTP) select the server you are using for that account
click on 'Edit'
deliberately make an error in the server name - remove the port details etc.
So the details are wrong and cannot send.
