Void program overload

Hi all

I m new on oracle & I'm trying to implement the subprogramme of overload concept. Below is my code

-The package Spec

create or replace package overloading1 as

function get_emp_row (p_empid number) return employees % rowtype;

function get_emp_row (p_last_name varchar2) return employees % rowtype;

function get_emp_row (p_department_id number) RETURN employees % rowtype;

end;

-Package body

create or replace package body overloading1 as

function get_emp_row (p_empid number) RETURN employees % rowtype as

employees x % rowtype;

Start

Select * x to employees where employee_id = p_empid;

Return x;

end get_emp_row;

function get_emp_row

(p_last_name varchar2)

RETURN employees % rowtype as

employees x % rowtype;

Start

Select * x to employees where last_name = p_last_name;

Return x;

end get_emp_row;

function get_emp_row (p_department_id number)

RETURN employees % rowtype as

employees x % rowtype;

Start

Select * x to employees where department_id = p_department_id;

Return x;

end get_emp_row;

end overloading1;

He has compiled. However, when I tried to run it via the command "exec" or anonymous block, I get errors.

When the command "exec" below

exec ('raja') overloading1.get_emp_row;  got the error like "ORA-00900: invalid SQL statement.

00900 00000 - "invalid SQL statement.

I then called the anonymous block. Got the error as attached (error.png)

declare

l_out varchar2 (4000);

Start

l_out: = overloading1.get_emp_row('raja');

dbms_output.put_line (l_out);

end;

A given number as a parameter like below & got "too many declarations error." Attachment with the name 'error2.png' contains the same

declare

l_out varchar2 (4000);

Start

l_out: = overloading1.get_emp_row (100);

dbms_output.put_line (l_out);

end;

Below is my table structure

100AA(null)(null)(null)22 JUNE 14
200Queen254000(null)MAY 22, 14
300Raja266000(null)22 APRIL 14

Kindly let me know as how to test it. Thanks in advance

Your function returns a RECORD while you assign to a function result string. Use:

declare

employees l_out % rowtype;

Start

l_out: = overloading1.get_emp_row('raja');

dbms_output.put_line (l_out.employee_id);

dbms_output.put_line (l_out.last_name);

...

end;

  • Void in projects, program

    Hello

    Can someone explain to me what is the concept of "* program *" and "* Sub program *" in the projects. Why is used.


    Thank you
    Sandeep

    On a simpler note:
    A project can be referred to as a "program". A program can be linked to several subprogrammes (which is nothing else than a program) and a program of sup can be
    related to a project.

    For example:

    Program: P1, tasks: T1, T2

    Sup program: P2, tasks: T3, T4

    Sup program: P3, task T5, T6

    Project: P4

    Void program P2 can be linked to P1, by linking it to the task T1.

    and Sub program P3 may be related to P1, by linking it to task T2.

    Similarly, project P4 may be related to sub program P2 in the binder to task T3.

    It is a kind of hierarchy, you can train using this relationship. It is useful to follow the dates of efforts etc. at the program level. Usually the dates
    and planned efforts will be integrated project-level program sup at the program level.

    More information in the Oracle project management user guide is there. Chapter 3, program management.

    Hello

    The concept of overload is class that contains the same method but different values of parameter names (it may not of parameters, the type or whatever it is). In this case if she calls only String() (if we as integer values), main method is really overloaded?

    The main method can be overloaded Yes, as you did in your code. But the main method is a bit special, so it would be stupid to overload.

    Also, no matter how much you surchargerez the main method, hand (String [] args) we're the only one who will be managed by the JAVA virtual machine.

    You could test it in this way.

    public static void main(String[] args) {
        // This is the entry point to your program _always_
        main(new int[] {1, 2, 3});
        main(1, "string");

  • Why can't I reply to comments on reddit? When I hover over the link to the answer, I see javascript:void (0) in the lower left corner.

    Some features of reddit do not work, including the ability to upvote/downvote 'save' and 'response' buttons on the comments. I see the message "javascript:void (0) ' in the lower left corner on the links doesn't work, so I guess it's relevant. Operation links show various long URLs instead.

    I have already uninstalled firefox and reinstalled. I deleted the cache and cookies. I have reset to factory settings. I have updated Java. I've updated Windows.

    Java and Javascript are not the same thing

    • JavaScript is an object oriented scripting language that allows you to create dynamic HTML pages, allowing you to process the input data and manage data, usually in the browser.
    • Java is a programming language, a set of libraries and platform of virtual machine that allows you to create compiled programs that run on almost all platforms, without the distribution of the source code in its raw form or recompiling.

    You can enter the Mode safe by the following text:

    • Hold the SHIFT key while double-clicking the shortcut from the desktop Firefox (Firefox must be closed)

    Your "V - Ben" extension looks really suspicious. You must disable that. It is more likely adware.

  • Recommendation of program database for a single project

    Let me cut to it:

    I have a great many tables and lists of contacts covering the course of 15 years, I'd actually like to mine for my business.  The data themselves are simple but too abundant ranging from phones (h, cell, work, cell of spouse) to email (same distinctions) and point of reference and addresses (kid, volunteer Committee, etc.). These are lists that mainly alignments of my children and school lists over the years to let you know that some have a lot of data and other very little, so each record when entered in a spreadsheet (currently done) will vary high to very little retail.  Number of records will be null and void.  The 'perfect' form will prove be a combination of several records as individuals will appear several times (after being in the same class for 3 years or on the football teams, or both).  I don't know I will be assess by names and addresses, etc.

    I learned from a number of people that the best way to clean it is to enter these data in a database like MS Access program (not available for the Mac) or FileMaker and stay away from spreadsheets.  I have a big bottom using spreadsheets, so I'm familiar with those can be difficult to handle how.  The challenge with FileMaker is the cost!  Again, this is a one-time project (I think).  I'm familiar with db interfaces and look forward to relearning the basics, get the error report to correct and select, etc.  Spending this type of money for such power seems useless and stupid, and - again - this is a one-time project.

    At the other end, I see there are so many other programs that I don't really know which is better suited for this task.  JUST as an example I looked at Tap Forms for Mac but I had the feeling that it is a good place to 'empty your life' and all of you for the follow-up of the list - I have that part covered.

    If all goes well, the 'devil in the details' above you gives the idea of what I have (I think) I'm looking for.  I hope that YOUR ideas and skills can help me.

    Thanks in advance for your consideration.

  • BitTorrent and Utorrent act like they you download, but then the program does nothing when I try to install or open.

    I tried to download the programs. It seems that they download, but installation does not work everytime I try to open it later. Utorrent and bittorrent, have not tried all the others. I read a q & a to move mimeTypes.rdf and done and restarted Firefox and redownloaded in the program, still nothing.

  • Disk is too slow or overloaded system

    In one of my projects, every time, he gets at the helm of the 9 it still gives me the "disk is too slow or overloaded system' warning. I have 24 GB of RAM, 6 core 3.33 ghz processor, my project running on an external hard drive, and I froze all my tracks with the exception of a few. I'm still all my bounced based vst tracks audio tracks as well. This message appears every time in the same exact spot of the song, which isn't even the most complicated part of the song. However, there is no problem to any other part of the song. I do everything at sampling frequency of 96 kHz, which I regret now and is probably the most problem, but nobody knows what I can do to fix this? Also, I have increased my buffer size, did know of course other programs were running and still nothing.

    Are there audio recorded into your song? If this isn't the case, you can set the 44.1 kHz sampling frequency. The question with regard to your question is: what happens at the bar 9? Try to mute the titles one by one until it clears up the question. A screenshot of your project can also help determine the problem.

  • XP installation will void the warranty

    Hello

    I hope I am in the right place to ask this question - find info on the Toshiba site is not very easy! I am looking to buy a laptop Toshiba with Vista preloaded, but want to partition the drive and put XP on the partition as a dual boot. What I need to know is, this will void the international guarantee? Or where can I find?

    Hope you can help!

    Thank you

    Don t worry buddy. Installation of all applications, programs, software and other operating systems will not void the warranty.
    I recommend that you first create a new partition in Windows Vista, and then you could try to reinstall Win XP on the new partition.

  • DLLImport for c# programming

    Hello

    I am programming with c#, I have the problem in the niVB_Initialize function,

    My environment: WIN7 32 bit, VS2013 community (compiled x 86)

    All tips to clear this?

    int a = 0;
    }

    } //Main
    } //class program
    } //namespace AUA_niVB

    The only thing I see in your code that I'm not sure is the use of "nivirtualbench.lib" as the name of the DLL; nivirtualbench.lib is a library to import for "nilcicapi.dll." I think that the syntax for pointer/address-from you with "unsafe" is correct, even though I'm more a C++ guy than a c# guy.

    I was able to use the following with the C API of VirtualBench. It also avoids the use of the keyword "potentially dangerous."

    Example of namespace

    {

    Class Program

    {

    public const UInt32 LIBRARY_VERSION = 17874944;
    public const nom_dll as string = "nilcicapi.dll";
    [DllImport (nom_dll, EntryPoint = "niVB_Initialize", CallingConvention = CallingConvention.Cdecl)]
    public static extern Int32 Initialize (UInt32 version, out IntPtr libraryHandle);
    [DllImport (nom_dll, EntryPoint = "niVB_Finalize", CallingConvention = CallingConvention.Cdecl)]
    public static extern Int32 Finalize (IntPtr libraryHandle);

    public static void Main (string [] args)

    {

    IntPtr libHandle;

    Initialize (LIBRARY_VERSION, out libHandle);

    do stuff with libHandle

  • How to overload a sequence?

    I want to overload the sequences TestStand operation can be overloaded in other programming languages.  By overloading, I mean I want multiple sequences with the same name and different parameters.  He appealed and enveloping the function much easier and cleaner.

    For example if I need 3 parameters for specific action, but I only have 2 and want to use the 'standard' for the 3rd parameter value, I take steps to get the third parameter inside a function with 2 parameters, and then call the function with 3 parameters.

    I put the standard quoted value because most of the time it will not be a digital fault.  It could be a piece of information obtained from a network or a field of another parameter, or anything really.

    I think you are badly understand what I'm telling you...

    The default values for common data types are:

    Boolean = False

    Digital = 0

    String =' '

    However, this is not what I am referring.  When you add a parameter to a sequence there are 4 columns: name, value, type, comment.  Under the comment of value that you put a value that you want to be the default. Let's say you have a digital set called Foo and you put 10 as value.  Now when someone puts down a call to this sequence sequence and they check the default zone for the parameter Foo the value will be 10 when he enters the subsequence.

    Edit: If you really want to try to check if the default value has been used:

    RunState.CallingStep.Module.AsSequenceCallModule.Parameters.Item (X). UseDefaultValue whre X is the index of the parameter you want to check.

    See you soon,.

  • void VI does not run with the main VI.

    My main and sub VI is attatched.

    Re: void / VI does not run with the main VI.

    When you start your main program, the Subvi is called and the main VI must wait the Subvi before it can continue. However, the Subvi is not set to open the Panel before, so very probably that it runs in the background for 100 seconds (1000 iteration to 100ms), because no one can press the stop button at the beginning to put an end to the Subvi. Once the Subvi is completed, the last value is returned to the main VI via the output connector and the main VI can process and display this last value. At this point, the main VI stops, because it's done (hopefully you do not "continuous operation").

    Obviously you have some misconceptions of beginners on the stream. Please we tell exactly what you expect the program to do, and we might be able to point in the right direction.

    On my laptop HP Envy M4-1015dx, I just changed a large image file in Photoshop, probably using a large amount of the work disk. In the background, I had another Adobe program running even though I had not committed the application within a few hours before. Google Chrome web browser was also opened in the background, with a lot of tabs open. Thus, the load on the processor of the computer /? was really heavy.

    At this point, the battery died and the computer turns off later. I plugged to a power source shortly after and you press the power button to turn on the laptop. The laptop starts and went to the Welcome screen, I entered my password and the laptop is stuck on the 'Welcome' screen that loads before opening on the desktop.

    I pressed the power button to turn off the laptop and again to turn it on. At this point, everything loaded very slowly. Screen where to enter the password moved extremely slow, taking at least 5-10 minutes to accept my activation key and begin to load the desktop.

    Using any other application did not work, they became unresponsive. Tent a restore of the system took more than 30 minutes just to set a restore point and 'prepare' the computer for a restoration of the system. I could never complete a restore, I got an error during the process of preparation.
