How to prompt for user input in PL/SQL

How do I prompt for user input in PL/SQL?
I am writing a piece of code where the user may choose, by clicking either of three buttons on an alert, to have the system assign a value to a variable, to input a value or to do neither?
If the user chooses to input the value I want to update a set of database fields with the value.
I have thought about showing a view where the value may be entered into a field displayed on that view. The value will be assigned to the variable by the user clicking a command button. The question I have in this case though, is whether, after the command button is clicked, control will be passed back to the code that called the view in the first place?

But if you call your procedure in that button then yes 'control will be passed back to the code'...

Desgordon,
This can be accomplished by displaying your message to the user using an Alert. I use 3 different Alerts (Note, Caution and Stop) in my forms and they are inherited from a central source file (such as an Object Library or a Template Form) so they can be used by all of my Forms. You can set the text of the Alert using the SET_ALERT_PROPERTY() built-in and capture what button the user presses with the SHOW_ALERT() built-in. Additionally, if you need more than one button to be displayed in an alert, you use the SET_ALERT_BUTTON_PROPERTY() built-in to rename the default button or to add up to a total of three buttons in the alert. Here's an example:
DECLARE
   Alert_ID       ALERT;
   v_AlertType    VARCHAR2(10) := 'CAUTION';
   v_AlertTitle     VARCHAR2(25);
   v_AlertText    VARCHAR2(150);
   n_AlertButton NUMBER;
BEGIN
   v_AlertTitle := 'Title of Alert';
   v_AlertText := 'This is message to the user.';
   /* Code leading up to the decision point. */
   alert_id := FIND_ALERT(v_AlertType);
   /* Note: I only set the Label of Button 2 because the default button 1 label is 'OK' */
   SET_ALERT_BUTTON_PROPERTY(v_AlertType, ALERT_BUTTON2, LABEL, 'Cancel');
   SET_ALERT_PROPERTY(Alert_ID, v_AlertTitle, v_AlertText);
   n_AlertButton := SHOW_ALERT(Alert_ID);
/* Now I can test the value of n_AlertButton for 1 or 2 to find out what button the user selected. */
IF ( n_AlertButton = 1 ) THEN
     /* Do something, because the user selected 'OK' */
ELSE
     /* It is assumed at this point that the user selected 'CANCEL' */
     /* Stop processing any further. */
     RAISE form_trigger_error;
END IF;
END:Hope this helps.

"catching" a prompt for user input and answering it through zenity?

I'm trying to write a script (or multiple scripts) that will allow me to use command-line only applications via user defined actions in my file manager without having to open a terminal. Now I realize this basic functionality is already available, but as it stands I am unable to respond to command-line prompts for user input without opening a terminal. Is it possible to write a shell script that would act as a wrapper and allow me to use zenity (or another popup program) to respond to such queries?
For example if I used a command-line program that prompted me for a password, could I "catch" that prompt with a shell script and answer it through another program, such as zenity?
Last edited by falconheart (2011-01-16 22:37:25)

The easier way to do this is to collect the info with zenity first, then pass it on the command line. If the program insists on prompting, then you could try feeding it the info with redirection if it accepts it from stdin. For example
command < info.txt
where info.txt is a temp file created by your script which contains whatever you want entered into the prompts. This will work in some cases.

How to force sql developer to prompt for user input for every execution ?

Hi Folks,
Environment: Oracle 11g (on Windows 7)
SQL Developer: *3.1.07*
I am executing a PL/SQL code off Sql Developer. The code uses substitution variables to prompt user for input. However,I am only prompted for the user input for the very first run of the code. For the subsequent executions, the code simply picks up the user input from the very first run. This behavior persists for all subsequent runs of the code.
I have executed the same piece of code from SQL*PLUS and the behavior seems normal (i.e. I am prompted for fresh input for every execution)
How can flush out the old user input so I can be prompted for new user input for every run of the code in sql developer?
Thanks in advance

Prompt For User Input in SQL Developer

I am using the '&' in a very basic SQL select script, but I do not get a prompt for my input. However, i have used the '&' in update scripts and it does prompt me.
For example:
select DCC_DESCRIPTION
from S_TBLDTMINOR
where DCC_DTMINOR = &Minor;
Gives an ORA-01008 error (not all variables bound).
If it's a varchar field and I use '&Minor' - it executes with no error, but does not prompt for data. Please note: this script works when it's run in SQL*Plus, but not in SQL Developer.
If I execute:
update S_TBLDTMINOR
set DCC_DESCRIPTION = 'Mark & Wilson'
where DCC_DTMINOR = 'AAA';
It does prompt me for a value (but I do not want it to).
So I know prompting works in SQL Developer, but it does not work in select statements.
Is this a configuration setting I can change in SQL Developer? I know I can use the escape in the update statement to avoid the prompt, but I'm not concerned with that. I'm trying to get the prompting to work in the select statement.

Hi user12289057,
1/Not sure what your testcase is (including table definition), I was trying to reproduce with:
select * from dual where dummy = '&myin'
2/Try
undefine Minor
to ensure Minor is not already set.
3/Minor may need to be quoted if it is a string.

How to Prompt for User/Pass Running Shell Script Remotely through ARD

So I finally got my Active Directory Script working! However, I realized that I'm not the only one going to be running this script and to have my user name and password in the script itself is beyond foolish. While I know it's possible just to have whoever's running the script to manually add their username and password, I'd prefer to have prompts to make things easier for the rest of my team.
Here's my current script. I've tested it on the machine I'm connecting to Active Directory and it works fine if you run it on the machine itself in terminal. However, I'm going to be doing this on about 150 machines and the whole point of the script is to do it remotely.
#! /bin/bash
MACNAME=$(scutil --get ComputerName)
read -p "User Name: " USER
read -p "Password for $USER: " PASS
dsconfigad -add "CORP.DOMAIN.NET" \
-username $USER \
-password $PASS \
-computer $MACNAME \
-mobile disable \
-mobileconfirm disable \
-localhome enable \
-useuncpath enable \
-shell /bin/bash \
-ou OU=Macs,CN=Computers,DC=corp,DC=DOMAIN,DC=net \
-force \
-localpassword "PASSWORD" \
-groups "GROUPS"
When I run the UNIX script through ARD to a machine, I get no prompts for USER or PASS. In fact, it gives me the following error "dsconfigad: Authentication server encountered an error while attempting the requested operation. (5202)" So it's not asking for a user name and password.
Is there any way to make a shell script prompt you for a User Name and Password when you're sending commands remotely through ARD? Or is there another way to do this?
Any suggestions would be greatly appreciated.
-rks

Best solution is to create an account that is exclusive to binding machines. By doing this, you can embed the user name and password in the script. Heck, you can post it on your website. If the account is configured properly, it will only be able to create machine records in a defined container. If you are mixing Macs and PCs in your AD domain, I also recommend creating an isolated container for your Mac records. Now, the account has even less access rights as you can make it so it only has rights to the Mac container.
Otherwise, ARD does not prompt. You can play around with an expect script but the reality is that you are still embedding the credentials in the script so it really does not achieve what you want. ARD is not an interactive shell scripting tool. It is more a fire and forget.

Prompting for user input in nested select statements

I recently rewrote a query to use a nested select statement instead of specifying every SELECT field on the GROUP BY line. Here's the query which works perfectly with hard-coded values of '030', '01/01/11', and '12/31/11'.
SELECT T0.[CardName] AS Customer, T0.[CardCode] as 'Cust ID', T0.[Phone1] as Phone, T0.[CntctPrsn] as 'Contact Person', T0.[Address], T0.[City], T0.[State1] as State, T0.[ZipCode] as 'Zip Code', T0.[Country], T1.[TotalSales]
FROM OCRD T0
INNER JOIN
   (SELECT I.[CardCode] AS CardCode, SUM(I.[DocTotal]) AS TotalSales
    FROM OINV I
    WHERE left (I.[CardCode], 3) = '030' AND (I.[DocDate] >= '01/01/11' AND I.[DocDate] <= '12/31/11')
    GROUP BY I.[CardCode]) T1
ON T0.[CardCode] = T1.[CardCode]
ORDER BY T0.[CardName]
When I try to prompt for the left 3 characters of the CardCode (or the dates), ie.
    WHERE left (I.[CardCode], 3) = [%0] AND (I.[DocDate] >= '01/01/11' AND I.[DocDate] <= '12/31/11')
I get an error "Column 'OCRD.CardName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause".
It's like putting a user variable in the inner SELECT made it part of the outer SELECT which is exactly what I was trying to avoid by re-writing this query with the inner SELECT.
Can anyone explain what SQL Server is doing here and how to fix it?

Thanks Gordon. That's how I originally wrote the query and it works fine. But I was disturbed that I had to GROUP BY every field in my SELECT statement when I really only wanted to group by CardCode. So I did some research and came up with this where the inner select still groups by only CardCode and still takes user input. I don't really understand why you need the commented SELECT statements in the SET lines, but you do. Something about using real table fields for variables.
DECLARE @startDate datetime
DECLARE @endDate datetime
DECLARE @rep varchar(10)
SET @rep /* SELECT T0.[CardCode] FROM ORDR T0 WHERE T0.[CardCode] */ = '[%0]'
SET @startDate /* SELECT T0.[DocDate] FROM OINV T0 WHERE T0.[DocDate] */ = '[%1]'
SET @endDate /* SELECT T0.[DocDate] FROM OINV T0 WHERE T0.[DocDate] */ = '[%2]'
SELECT T0.[CardName] AS Customer, T0.[CardCode] as 'Cust ID', T0.[Phone1] as Phone, T0.[CntctPrsn] as 'Contact Person', T0.[Address], T0.[City], T0.[State1] as State, T0.[ZipCode] as 'Zip Code', T0.[Country], T1.[TotalSales]
FROM OCRD T0
INNER JOIN
   (SELECT I.[CardCode] AS CardCode, SUM(I.[DocTotal]) AS TotalSales
    FROM OINV I
    WHERE left (I.[CardCode], 3) = @rep AND (I.[DocDate] >= @startDate AND I.[DocDate] <= @endDate)
    GROUP BY I.[CardCode]) T1
ON T0.[CardCode] = T1.[CardCode]
ORDER BY T0.[CardName]

Increasing max # of inputs on prompt for user input

Hi
I would like to increase the number of inputs beyond 10 available on the prompt user for input function. At the moment I am using 9 of the 10 available inputs each running a subVI from a case structure. I seem to be limited to 10 inputs using the prompt user for input function so is there another way of prompting the user to select from >10 inputs preferably 20.
Thanks for any help

You can always write you own dialog with as many selections as you like.
Right-click the express VI and "open front panel" This will convert it to a VI that you can edit in any way you want. save it under a new name.
You might even want to add some validation code, e.g. to make sure that no more than 2 boxes are checked.

How to create an user input variable for customer exit variable? - BW3.5

Hi Guru,
I have a requirement for the selection period of my reports. There are 3 possible reporting periods which should be user selectable:
1. Month: Current reporting month
2. Fiscal Year to Date
3. Project Year to Date
Here I need 2 variable to do these, 1 customer exit and 1 user input variable. I have created a variable customer exit to calculate all these requirement. But can any1 tell on how to create the user input variable for my customer exit? I need a user input variable with drop down list like below.
01-Current month
02- Fiscal Year to Date
03-Project Year to Date
I have create a new master data for this variable, but it's not working. What I need now is a standalone master data which do not need to link to any exiting records. Can any1 tell me how to create this?

Just go to the definition of the variable for which you have created a customer exit. There you will find a check box for "Ready for Input". Just tick that checkbox and the variable will be available as a selection variable in the reports selection screen.

Yogesh

How to generate the User-Input XML Body for executing workflows via REST APIs: The Solution

I see that executing a workflow via REST APIs requires lot of work to be done just to prepare the right User-input XML body. Any mistake and you have some major debugging to do. Larger the number of User-Inputs, the bigger is the problem.Life is so much easier at the WFA GUI with Display names and tooltip help for User Inputs which are very easy for reading and providing the right values. I don't have any such privileges when manually preparing the User-Input XML body.It’s been asked numerous times how to provide User-Input values for type table, or Query (Multi-Select) etc. These are complex User-Input types and has lots of scope for user mistakes.I can have User-input dependency at WFA GUI which allows me to make the right selection, but while preparing my XML body I need to take care of it myself.An operator is allowed to execute workflows, but the same Display names which help him make the right user-inputs, makes it impossible for him to prepare the user-input body xml. Display names can't be used in in XML body and he can't know the exact parameter names by looking at the Display names. So he need to always contact the Admins/Architects for this. And Architects/Admins can't be expected to keep providing User-Input XML body to operators every operator. How about if I could enter all the User-Input values in my workflow execution at WFA GUI, I can do a preview which passed to my satisfaction and then I can magically get the XML body for it which I can use to execute my workflow from REST APIs from any client. It could be so very much easy for me than building my User-Input XML body manually. This is exactly what I'm going to give you right now. You open the WFA in browser, Go to your workflow, Start execution, you input values from GUI reading carefully the display names, preview it to your satisfaction and then get the XML body. Assume your workflow is called “Workflow to Print a given Message”. It’s a simple workflow with only 1 user-input Displayed as "Message to Print" Prerequisites: The following are the one-time prerequisites. You need PowerShell 3.0 on your WFA server.Import the attached Generate_Workflow_User_Input_Body_in_XML.dar in your WFA. It’s our magical command called "Generate Workflow User Input Body in XML"Add credentials of a WFA Admin/Architect in you WFA itself with Name/IP: localhostMatch: ExactType: OtherName/IP: localhostUsername: <WFA Admin/Architect Username>Password: <User Password> Steps: Suppose you have a workflow called "Workflow to Print a given Message". You want to execute it from REST apis and need to prepare the user input XML body. Select this workflow and clone it. The workflow clone is the exact copy of your original workflow word by word, input-by-input. It will open in Edit mode with name "Workflow to Print a given Message - copy".Add the command "Generate Workflow User Input Body in XML" at the beginning of your workflow. This is a must. This command need to be the first command in your cloned workflow.This command requires no input. So for its Parameters just press okay and save the workflow.You are done.Now Execute the clone workflow. You'll see all the user-inputs available to you. Make your choices as you wish. Preview it to confirm that planning is passed and u have no errors.Execute it now.You'll see that the our magical command "Generate Workflow User Input Body in XML" has failed in our clone workflow execution. Don't worry, its fate was decided to be so. But it didn't fail before giving me what I really wanted. i.e. my XML body for my real workflow. It displayed it in the GUI as well as saved it in your WFA server @ C:\temp\<workflow_name_dd_MM_yyyy_hh_mm_ss_.xmlIt also deleted all the reservations of this particular failed job. So NO major residue left to be cleaned.To summarize: Clone Your workflow and Add the command "Generate Workflow User Input Body in XML" as your first command. Start Execution, provide your User-inputs and preview it. Be satisfied and Press Okay. Now Execute it. After a few scconds this cloned workflow will fail with Error "All done. The Workflow will fail now." See the command execution logs for this command. You'll see the User-Input XML body. It has also saved the XML file at C:\temp in your WFA server. Have fun. sinhaa

How do you keep a VI running while waiting for user input?

I have a VI that:
1. The user enters set points.
2. The user starts the VI and the VI sends the set points to an external process via a serial interface.
3. The VI stops running.
4 The user waits for the external process to complete.
5. Repeat sequence. Go to Step 1.
This works well except for one small problem. Starting the VI in step 2 causes an external micro controller to reset. During the reset it will ignore set point commands. To get around this problem a delay has been added between when the VI opens the serial port and when the VI sends the set points to the external process Is it possible to keep a VI running continuously in this type of application, thereby eliminating the start up and shut down of the serial interface?
If yes, how do you keep a VI running while waiting for user input?

The ones for the event structure specifically. I'm posting from my phone. Look at the basic ones for user input. even a simple while loop with a boolean and a case statement would work.

How to make Flash to wait for user input

Hi,
I found this PHP script, then I made some changes to make it
FEED the Flash user interface with online user input.
The main concept of this script is WAITING for user input, so
it shows the messages and then go to next line and so on.
The user input go to directly to TEXT file which writes in
lines, each line has a unique id = (mag_id).
There "get_msge.php" which works as the middleware between
FLASH and messages text file.
The problem, its doesn’t show any data while there are
data in the text file.
Help here please, best regards.
This is the link of
problem illustartion
AS is:
// create an object to store the variables
varReceiver = new LoadVars();
// load the variables from the text file
varReceiver.load("get_msg.php?file_id=1&msg_id=1",
"POST");
// trigger something - when the variables finish loading
varReceiver.onLoad = function(){
//the variables have finished loading
if (this.msg_id == 1) {
_root.xmsg1_swf.text = this.msg;
_root.xmsg1_ch.text = this.msg;
gotoAndPlay("line2");
} else {WAIT }
PHP is:
<?php
//get these values from the FLASH
$file_id_swf = $_POST ['file_id'];
$file_name = "messages/messages".$file_id_swf.".txt";
$msg_id_swf = $_POST ['msg_id'];
// [0] ."||".[1] ."||".[2] ."||". [3] ."||".[4]."||". [5].
//$msg_id."||".date."||".time."||".$from."||".$to."||".$msg.
$fp = fopen ($file_name, 'rb');
while (!feof ($fp))
$msg_txt = fgets ($fp, 1024);
$line = explode ("||", $msg_txt);
$msg_id = $line[0];
$from = $line[3];
$to = $line[4];
$msg = utf8_encode ($line[5]);
if ($msg_id == $msg_id_swf)
echo
"msg_id=".$msg_id."&from=".$from."&to=".$to."&msg=".$msg;
}//while
fclose ($fp);
?>

Well, given the things that you've written, I don't think it
could. There technically isn't any code in flash that lets it
"wait." In order to "wait," you must run the script over again
until some condition is met.
However, your code does look accurate. Why do you need to
wait? The onLoad function will be invoked WHEN something is loaded.
So, I don't see the reason for the "waiting."
In addition to that, I would like to say that using text
files isn't that great with flash. I have done this before and
noticed several problems with using text files. The biggest problem
is that the text files are cached after being loaded. Every time
you re-load it again, you will get what you got the first time
until you reset your cache (ie. close your browser). I suggest
using MySQL. (Just my thought.)
