• General doubt in the procedure

  Hello all;

  
  

  I learn PL/SQL procedures.

  i don't understand what I marked red following below.

  
  

  > > This code from web > >
  

  
  

  CREATE OR REPLACE PROCEDURE employer_details

  IS

  CURSOR emp_cur IS

  SELECT first_name, last_name, salary FROM emp_tbl;

  SheikYerbouti emp_cur% rowtype;

  BEGIN

  FOR SheikYerbouti in sales_cur

  LOOP

  dbms_output.put_line(emp_cur.first_name ||) ' ' || emp_cur.last_name | ' ' || emp_cur.salary);

  END LOOP;

  END;

  /

  REF_LINK: http://plsql-tutorial.com/plsql-procedures.htm

  My questions are:

  sales_cur indicates what?

  When using the loop can we use variable_name to start the loop?

  
  

  I mean I'm trying to run above the code for my personal data according to my emp table.

  If I'm not above doubt slot I can't finish my auto - practical.
  

  
  

  SQL > desc emp;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EID                                                      NUMBER

  ENAME VARCHAR2 (15)

  VARCHAR2 (10) EQUAL

  ESALARY VARCHAR2 (15)

  ECITY VARCHAR2 (15)

  EPERK                                                NUMBER

  NUMBER OF ECONTACT_NO

  Thanks in advance!

  Reading is one thing. Try another. Try to run the code in the comic book. (Maybe you can try apex.oracle.com)

  You will discover that this does not compile for several reasons.

  One is

  emp_cur.first_name: this must refer to the current line of the cursor loop, which is SheikYerbouti, so it should be emp_rec.first_name.

  Second is

  sales_cur is not declared, it is rather called emp_cur.

  Below is the modified code so that it works in my diagram

  CREATE OR REPLACE PROCEDURE employer_details

  IS

  CURSOR emp_cur IS

  SELECT ename FROM emp;

  SheikYerbouti emp_cur % rowtype;

  BEGIN

  FOR in emp_cur LOOP

  dbms_output.put_line (emp_rec.ename);

  END LOOP;

  END;

  you run it this way

  Start

  employer_details;

  end;

  In my case output is

• MySQL GPL license

  Hi all

  I have a general doubt about the GPL license. I hope you can help me find a clear answer...

  Let's say I want to build a java portlet or a java application that connects to the engine of MySQL Community Edition database by the official MySQL JDBC connector, which is under GPL license.

  Question: is there a any restriction on the importation and use of the pot of connector JDBC (not the source code) in the project from the point of view of copyright and/or commercial use?

  I mean, if I just use the pot in my project, am I still free to sell my application and protect it with copyright or it automatically goes GPL license too?

  I hope that the issue is pretty clear.

  Thanks in advance for the answers.

  How to convert Blu Ray Disc of the movie in general video and HD video formats

  Hello

  I doubt that this is possible because Bluray discs are mostly protected against copying.
  But if you have the Bluray m2ts file on your HARD drive, then you could try the tool called convertXtodvd. But I don't see that the reasons for this
  I mean that you will lose the quality of film converting the blueray to dvd.

• "conditional" checkbox in the General/console/process design of a process definition tab

  Hello

  According to Oracle® Fusion Middleware for Oracle Identity Manager 11 g Release 2 (11.1.2.2.0) Developer Guide, section 5.3.3.1 ('general tab'), the conditional check box has the following meaning:

  "This checkbox determines if a condition is met to add the task of current process to the process.

  Select this check box to prevent the process task to be added to the process, unless a condition has been met.

  "Clear this checkbox require is not the condition must be met for the task process be added to the procedure.

  Please clearify the following questions:

  (1) where exactly define these conditions?

  (2) what conditions are possible? (Complete list or link to documentation)

  (3) where exactly (link, document, chapter) is it is documented in detail?

  Thank you and BR,

  Max

  Hello

  1) its a check box available in the console Design-> Process Management-> process definition-> task-> task-> conditional box properties

  (2) two types of conditions are possible. Otherwise-> task will be call by default whenever the resource is currently in use.

  If verified--> the task will not be called unless its being triggered by an action. (Thanks to a reaction-> success, or using the code)

  (3) I think that the link you share has everything what is necessary.

  Let me know if in doubt.

• several doubts with vmware esx 3.5

  guys, I had many doubts on VMware ESX. can you please answer me if you know the answers to any of the sub questions

  In the meantime thanks for all those who respond to my questions.

  (1) how to install ESX on the SAN to start on the SAN?

  (2) how to back up the database to the virtual Center Server? is it something that supports a SQL DBA or do we do as a VMware administrator?

  (3) for the installation of VCenter server, its request for the installation of the apache tomcat server. Why is this? It is with ESX 3.5

  (4) do we need a separate license for VCenter server apart from the licenses that we buy for the ESX servers?

  (5) if 2 virtual machine port groups are on two different VLANS, to send it, we need to configure a vyatta router. How can we do that if we are not a guy from Cisco?

  (6) we give only the IP numbers for a console Service and Vmkernals but not the virtual machine port groups. If so, how these virtual machines on these virtual machine port groups know what are their IP numbers? If we want a static IP number for a virtual machine, we inside windows from a virtual computer configuration?

  (7) is the Virtual Machine power off a soft stop?

  (8) what happens when we make one pause a Virtual Machine? I think that there is no option in a machine physical windows original. so, what does this mean VM break?

  (9) how many vsphere client can simultaneously access the vcenter Server?

  (3) for the installation of VCenter server, its request for the installation of the apache tomcat server. Why is this? It is with ESX 3.5

  Don't know why VM Ware chose Tomcat, they SAY THEY is not secure... No matter what.  It's just another Web server and its an option that VM Ware has chosen to work with vCenter.  It's not good or bad, just different... many people THINK apache is better, it is a matter of opinion.

  (6) we give only the IP numbers for a console Service and Vmkernals but not the virtual machine port groups. If so, how these virtual machines on these virtual machine port groups know what are their IP numbers? If we want a static IP number for a virtual machine, we inside windows from a virtual computer configuration?

  It is a way, you will realize quickly that will be a major pain.  I do like DHCP, reserve of the INVESTIGATION period.  Unless you know a way to connect to hundreds of virtual machines and change their IP remotely, this is probably the simplest method.  Unless you like make manual updates... then knock you out.

  (7) is the Virtual Machine power off a soft stop?

  Not as the name suggests it is a POWER-off.  Comments stop is a soft stop.

  (8) what happens when we make one pause a Virtual Machine? I think that there is no option in a machine physical windows original. so, what does this mean VM break?

  Confusion in the name.  It simply means 'suspend' and there is an option on physical machines... probably no servers, in the form of profiles of power are generally disabled, but it IS possible.

  (9) how many vsphere client can simultaneously access the vcenter Server?

  no theoretical limit... or I do not think that someone took the time to discover.  You will grow up to the moment where you have too many users connected to vCenter vCenter anyway... So the connections will not be reached.

• Doubts basic creation/modification of a Module

  Hello
  
  I'm a newbie at ATG, and I'm trying to understand how ATG (I work with ATG for just one week). I have some conclusions on ATG and I just want to confirm that I have just do.
  
  Configurations:
  Application server: WLS (Weblogic Server 11g)
  Version of the ATG: 10.0.3
  Database: Mysql
  Official database: Oracle
  IDE: Eclipse
  Develop the operating system: Windows 7 (yes I know linux isn't it better... but...)
  Official OS: Oracle Linux
  
  Conclusions and action I got:
  1. While ATG is a module
  2. do I need to create a new module to create a new store, or I have to work more crs?
  2.1. I have both, a new module and ReferenceStore under Eclipse IDE with all the taglibs and packages to work, I'm able to generate a constituent of any
  2.2. with this war, I'm able to run runAssembler.bat - pack xxx.ear m XXXECommerce Module and it generates a .ear
  2.3. with this .ear I'm capable of doing a deployment to WLS. (It runs without error to WLS but page index.jsp and all other open white and one occurs NullPointer interpretation tag dsp)
  
  Doubts:
  1 are. these conclusions correct?
  2. with my customizations in a .war do I do if erros happens running runAssembler and deployment?
  3 does anyone have a tutorial on how to create a new ecommercer site or how to use a crs as reference to build a store?
  
  Thank you!!

  You must run runAssembler as many times have you create ear files.

  In general, intermediaries, and Production will be same file ear with only a difference for data source files.
  These data source files, you can put in the localconfigs of specific server.

  The publication, you must create a new module and add the list of modules required in his MANIFESTO. MF file.

• Doubts in functions and procedures

  Hello world
  
  Can someone tell the exact differences between function and procedure?
  
  My doubts are
  1. If the procedure can return and is not necessary it must return a value (in other words, if we want to come back and is not as one can write procedure) then why do we need to function?
  
  2. I tried to call a function that updates a table in the code, I got an error saying that the function does not use DML.
  
  3. I want to know the combination that
  procedure a. can call a function and vice versa?
  b. function (which uses DML instructions) can be called from sql statement?
  and if all other combinations are there let me know with reasons.
  
  Thanks in advance,
  Vinay

  Have you looked at in the [reference Guide and the User Guide for PL/SQL | http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/toc.htm] already?

  http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14261/subprograms.htm#i4074

  (1) for example: functions can be used in SQL, procedures cannot.
  (2) generally, the methods are used for DML.
  It depends on how you are performing the function:

  hoek&XE> create table t as select 1 col from dual;
  
  Tabel is aangemaakt.
  
  hoek&XE> create or replace function f
    2   return number
    3   as
    4    num number;
    5   begin
    6    update t
    7    set col = 2;
    8    num := sql%rowcount;
    9   return(num);
   10  end;
   11  /
  
  Functie is aangemaakt.
  
  hoek&XE> select f from dual;
  select f from dual
         *
  FOUT in regel 1:
  .ORA-14551: cannot perform a DML operation inside a query
  ORA-06512: at "HOEK.F", line 6
  
  hoek&XE> 
  
  hoek&XE> var num number
  hoek&XE> exec :num := f;
  
  PL/SQL-procedure is geslaagd.
  
  hoek&XE> print :num
  
         NUM

           1
  
  hoek&XE> select * from t;
  
         COL
  ----------
           2
  

  Yes 3A)
  No. 3B), see 2.

• Settting of report interactive user customized - cool savings generals?

  What, if any, is overload by allowing users to save their own settings custom interactive report? I looked through all the documentation and I was not able to find something about how the settings are saved and what is the associate overload by allowing end users to do.
  
  Any information would be greatly appreciated.
  
  Thank you
  
  Mark Moran

  Mark,

  Do you mean overhead in terms of storage or performance?

  In my opinion the benefits certainly outweigh the disadvantages here (if users can create/filter/etc. their own reports without having to return to developers, then it costs is well backed up generals).

  However, I appreciate that in high volume sites, it would be undesirable to have a large number of end users, creating "unlimited" amounts of custom reports themselves. Perhaps a future improvement could be made to be able to limit the number of reports by user? Although realistic, I doubt many users would create hundreds / thousands of report parameters, if really there a matter of economies of scale?

  John.

• Settings > general > keyboard > shortcuts toggle?

  I am running iOS 10.0.2 on my Plus 7 iPhone and my iPad 12,9 Pro.

  When I go into settings > general > keyboard IPAD Pro, there is a "Shortcuts" under the rocker switch to "Enable Caps Lock" and above the toggle to "Predictive". (Note that the rocker "Shortcuts" also appears on an iPad running iOS 10.0.2). 2 Air

  On iPhone 7 more, however, there is no such rocking "shortcuts".

  Because, on this same page settings, both devices have an "Alternate text" option that you can type on enter custom keyboard shortcuts, I have no idea what the rocker "Shortcuts" on iPad is for.

  I did on 1 million various searches on Google and you have not found the answer.

  Could someone kindly enlighten me?

  Thank you.

  The shortcuts are for tools to the left and to the right of the top of the keyboard that you see here. The iPhone screen is probably too small to make use of this feature.

  Shortcuts for editing text and paste it from the Clipboard.
