Best way to present a query recordset to a remote server

What is the best way to move the data from the app and Server data structures?

There is probably another way to get here, but in Developer SQL, on the navigation tree, expand objects until your table, right-click, and then click EXPORT... you will see all the options. It is a tedious process and it sucks IMO, but yes, it works. This is zero especially because 1) it's a table at a time, 2) If your data model is robust and has constraints and sequences and triggers, then you will need to disable all for the insert and we hope you can re-enable constraints, etc. without hitch (good luck, unless you have only a handful of tables)

I prefer to use the oracle EXP command-line to export an entire schema, then the server target, I use IMP to import the schema. In this way, it is almost true. This makes the dirty life if you develop multiple applications in a single schema, and I felt pain - however - it is much easier to drop the tables and other objects is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. blow everything you don't want on the target after the fact...)

You can use method datapump oracle too.

If not, what can be done, IF you have access to both servers of your instance of SQL developer (or if you can tnsping both already from the command line, you can use SQL * MORE), is to run a script that will identify the objects of your applications apex (usually by the prefix for the names of objects, such as % EBA_PROJ_ etc.) and do all the manual work for you. I've created a script that does just that so that I can pass data from dev to prod servers on a dblink. It is difficult because of the order that must be executed to disable constraints and then turn it back on and of course, more complicated if don't always precede you ALL your "objects demand '... (tables, views, triggers, sequences, functions, procs, indexes, etc.)

best way to write this query

 

create table deals (id_prsn number, id_deal number, fragment number); 
create table deal_values (id_prsn number, id_deal number, value_ number, date_ date); 

insert into deals values(1,1,50); 
insert into deals values(2,2,40); 
insert into deals values(1,3,50); 
insert into deals values(2,4,80); 
insert into deals values(1,5,20); 
insert into deals values(2,6,80); 

insert into deal_values values(1,1,10 ,sysdate - 3); 
insert into deal_values values(2,2,208, sysdate - 3); 
insert into deal_values values(2,4,984, sysdate - 3); 
insert into deal_values values(1,null,134,sysdate - 3); 
insert into deal_values values(1,1,13, sysdate - 2); 
insert into deal_values values(2,2,118, sysdate - 2); 
insert into deal_values values(2,4,776, sysdate - 1); 
insert into deal_values values(1,null,205,sysdate - 1); 
insert into deal_values values(2,null,-5,sysdate - 1); 

 

select *from ( 
select a.id_prsn, 
       a.id_deal, 
       a.fragment, 
       b.value_, 
       b.date_, 
       max(b.date_) over (partition by b.id_prsn, b.id_deal) max_date 
  from deals a 
inner join deal_values b 
    on a.id_deal = b.id_deal or b.id_deal is null 
   and not exists  (select 1 from deal_values 
                              where id_prsn = a.id_prsn 
                                and id_deal = a.id_deal) 
   and a.id_prsn = b.id_prsn 
) 
where date_ = max_Date; 

 


    on a.id_deal = b.id_deal or b.id_deal is null 
   and not exists  (select 1 from deal_values 
                              where id_prsn = a.id_prsn 
                                and id_deal = a.id_deal) 
   and a.id_prsn = b.id_prsn 

Here's a different approach:

select * from (
  select a.id_prsn, a.id_deal, a.fragment, B.value_, b.date_,
  ROW_NUMBER() over(
    partition by a.ID_PRSN, a.ID_DEAL
    order by B.ID_DEAL nulls last, B.DATE_ desc
  ) RN
  from DEALS a
  join DEAL_VALUES B
  on a.ID_PRSN = B.ID_PRSN and a.ID_DEAL = NVL(B.ID_DEAL, a.ID_DEAL)
)
where rn = 1
order by 1, 2;

"nulls last" is the default sort order; I just put that for clarity.

Ask your host if they have a form-to-email script server you can use.

The success.html is something create you separately and reference in the form-to-email script.

Best way to download multiple ISO/models to an ESXi Server

We put a lot (about 70) Server ESXi (standard license).  Each server will go to one of our remote offices that is connected through a link that we cannot push a lot of data using...   We have ESXi 4 U1 installed on each server.  Now we try all our models and the ISO copy on each server.  Initially, we thought that we would be able to connect to your laptop with the client and download files in storage.  This works, but takes forever.  We have about 20 GB of data, and it took about 2 hours per server...   So we thought that we could do it once and then use Ghost to clone the drive we have created...  This also seems to take forever.  Does anyone have ideas on how to do this?

Thanks for all the ideas.

Best way to display a set of data rows (15 + columns)?

Hey,.

I have a set of data rows in a data from a JAVA call control. Rowset contains about 15 + columns of data that I need to display to the user in a grid. What is the best way to achieve this? When I try to drag the control of data lines in the AMX only obvious choice page seems to be seen list but I can't just use some columns in a list view. Or an iterator. I guess I should use iterator somehow, but what is the best way to present this data?

Manually, you can go and edit the list to add more columns and place fields in them.

Check out the application workbetter to see some models list (for example, people discovered) sample.

Oracle Mobile Application Framework samples

You might want to rethink your design and have a limited set of fields appear in the list, and then when you select a list item data show the rest of the info.

a very large list is perhaps not ideal for a mobile screen.

Best way to get vCenter Server VM

I would like to spend our vCenter server from one physical machine to a virtual machine.

What is the best way to go about this?

The current Server vCenter running Server 2003 R2 Standard x 64 Edition with SP2.

I want to move it to a virtual machine running Server 2008 R2.

I don't have something special, installed with the server vCenter Server. Running Essentials Plus licensing.

2 host ESX 4.1 with one on the way. New host will be ESXi 4.1 update 1.

Thanks in advance.

What is the best way to optimize a SQL query: call a function or doing a join?

Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

Best way to export from Indesign CS5 for Ipad presentation

Hello, I want to create a portfolio of our work to put on an Ipad, so I can show it to my clients. Would be nice if I could slip through the different screens by scrolling with my finger. Now that I read a few articles about it, but still I can't find out what is the best way... Interactive PDF is not supported on Ipad (?) so I should create an e-book, but which is the best way? Or is it better to simply add a few images in my photofolder and simply scroll through them?

Thank you very much for your answers!

There you go. You already have the opportunity to browse the images and run them in a slide show. There is no need to complicate things with PDF/ebook.

Hello

You don't want to make several clauses UNPIVOT and PIVOT; you want to do several sets of columns in a cluase PIVOT and UNPIVOT one clause.

In the UNPIVOT clause, it's just a matter of replacing the unique "amt" column before the keyword FOR with a list in parentheses '(amt_1, amt_2)' and the replacement of each column in the list (for example, "month_a_amt") with a list of the same length ("(month_a_amt_1, month_a_amt_2)" ").
In the PIVOT clause, it's just a matter of replacing the unique "SUM (amt)" aggregate function with a list of unparenthesized of functions, each with an alias ("the SUM (amt_1) AS amt_1, SUM (amt_2) AS amt_2'. The alias that will be added at the end of the givien for names output column in the IN clause.

SELECT       id
,       TO_CHAR ( ADD_MONTHS ( TO_DATE ( 'Nov 2009'
                                        , 'Mon YYYY'
                          )
                      , month_num
                      )
            , 'Mon YYYY'
            )          AS month
,       product_a_amt_1
,       product_a_amt_2
,       product_b_amt_1
,       product_b_amt_2
,       product_c_amt_1
,       product_c_amt_2
FROM       test_base_table
UNPIVOT       ( (amt_1,         amt_2      )     FOR month_num IN (
         (month_a_amt_1, month_a_amt_2)     AS  0,
         (month_b_amt_1, month_b_amt_2)     AS -1,
         (month_c_amt_1, month_c_amt_2)     AS -3,
         (month_d_amt_1, month_d_amt_2)     AS -4              )
       )
PIVOT       ( SUM (amt_1) AS amt_1
       , SUM (amt_2) AS amt_2 FOR product IN ( 'ProductA' AS product_a
                                                    , 'ProductB' AS product_b
                                   , 'ProductC' AS product_c

       )
ORDER BY  id

It looks like all the new values of amt2 are 9. Don't you think it's the best test? I think that different numbers, as you used for the examples of previous data, reduce the chances of getting good results purely by chance.

If you want to experiment with queries like this, I suggest you use "SELECT *" (nothing added) in the SELECT clause. Start with just an UNPIVOT operation. Some examples in the documentation to do a TABLE CREATION AS... to save the results of an UNPIVOT operator and use this table as the base for a PIVOT table. I think it's a good idea to reduce confusion.

What is the best way to inform your client of VCentere when a vmotion event has occurred?

Again, the alarm is once configured on the server vCenter Server and this can be done by using the Client vSphere or programmaticlaly using the vSphere API. The action of the alarm go can be anything and who is also stored and executed on the server vCenter Server. If you want the action to send an HTTP request, you can, as long as the 'scenario' can be run on the server vCenter Server. It's the size of the default actions that have been implemented with an alarm (alarm in vCenter system as event, SNMP trap, e-mail or run local script to vCenter Server)

If you want to develop a thin client that watches for a change or a particular property, you'll want to take a look at the collector of property if you have not already in the vSphere Programming Guide - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsdk_prog_guide.pdf in collaboration with collector property, you'll want to take advantage of "Views" which is what the vSphere Client uses to display the vSphere infrastructure inventory and updates only the customer when something changes or automatically when a view is modified (for example, cluster/host to view vm/model). You can still use the method of the alarm, but relying on the collector of property/views, will give you a solid client without having to query the system.

I would recommend that you take a look at these two presentation by one of our engineers on the manifold of the property http://vimeo.com/16222275 and http://vimeo.com/16215337 alarms & events
