URGENT: Autonumber to use next AVAILABLE value

Hi All
I urgently need your help: I am writing a Java assignment using a MS Access database. Some of the columns are AutoNumber used as primary keys in a relationship.
The program sometimes needs to delete records. The problem I have is that when I add new records the driver should use the next available number not the next sequential number.
ie.: If I have the records 1 2 3 4 5 and I delete record 3 I have
1 2 4 5.
When I now add a record, I want it to assign the number 3 to the record instead of the number 6.
There must be some work-around. PLEASE help me here!
Kind regards,
Comlink

What you need is called a sequence. Access doesn't have this. But you could make a table with one number field and write code to increment or decrement this number on confirmed updates.
Just an idea.

Configuration "use next available filename" in "write measurement file" function

My project recording signal and saving using "Write to Measurement File" function. I want to perform record multiple segments signals should have configured option "use next available filename". For example, if the original file is data.tdms then it will save the file into: data_1.tdms, data_2.tdms, data_3.tdms, ...
To do that I use a button control enable and disable write functionality.
In the past I have done normally. Now, I can not make it anymore, now every write new data were add into one file created without the next new file as desired, it has almost become a option "Append to file".
I use LabVIEW 2013
Solved!

Hello ducta9,
It looks like you currently have the Write to Measurement File Express VI configured to "save to one file" - this means that all data from a given session will be saved to the same file. The file number will only be incremented once the application is restarted or the Reset Boolean input is set to True. If you want to save to a series of files, select the "save to a series of files" option and configure the Express VI as needed to generate new files at intervals.
If you want to write variable-size chunks of data to a new file every time the user clicks the Enable button, you might be able to get away with just wiring a True constant to the Reset. I would still recommend taking a look at the options available in the save to a series of files settings.

Thousands of individual .txt files being created while using "next available file name" option in Save to ASCII step

I'm using Signal Express to record Load vs Displacement data and export it to a format our engineers can work with (in this case ASCII is okay). It would seem that by selecting the Next Available File Name from the drop down arrow it would do just that. For instance a typical save path for me would look like C:\....Desktop\Project Number and Description\Run_1.txt within that Run1.txt file would be all the data points for that run. When I hit record again Signal Express would (SHOULD) create a Run_2 since it's the Next Available File Name.
But instead what it does is creates a single txt file for every single sample point being read. Needless to say, If I'm recording 6 second of data at 1khz I end up with thousands of txt files!
The first thing that comes to mind is, why would anyone want this?
Second is how can I record multiple individal runs for the same project and have the file name increment?

...and more attachments of the ASCII save path, before and after acquiring 4 seconds of data along with one of the files from that folder.
Again, this is 4 seconds of two-channel spring plot data at 100 Samples to Read @ 1k Rate (Start Run.... wait 4 seconds or two full test sample cycles... Stop Run).

The .txt file would not attach (I think it's too small). Here's what it looks like if you were to open it:

Also, for some reason it won't let me attach my project file. It's a .seproj extension but the forum thinks it's 1k in size and "empty"

RMAN backups not using next available volume: uses next unlabeled volume

Greetings.
I've noticed that sometimes (haven't zeroed in on when yet) when RMAN backs up using OSB, the first tape in the library, an RMAN volume, is grabbed and backed up to.
There are about 10 other RMAN-labeled volumes right below that first one. But RMAN will take an unlabeled volume further down in the library, label it as an RMAN volume, and proceed to back up to it.
This is happening often enough where my library is filling up with partially used RMAN volumes.
Three jobs (that I can see so far) are cron jobs calling an RMAN script. I'm looking for the other jobs which, I think, are run via OEM.
Any thoughts?
-Jeff

Our daily backup is doing the same thing. That is, it's not backing up to tapes I assume it'll use. This is in the transcript:

Multiple Available Values in Parameter

I have a query like Select * from Table where column in (@Parameter)
@Parameter has two choices.
Choice 1 value is 01 or 05. Choice 2 value is 04 or 06.
If Choice 1 is selected for the parameter, I want the query to result into Select * from Table where column in (01, 05). This should show results for rows where Column is either 01 or 05. "Column" is a text data type.
How do I use multiple available values in a parameter? I found this post
http://social.msdn.microsoft.com/Forums/en-US/a484ceb0-78f8-472e-ae96-d48f85ea25b7/multiple-values-in-available-values-non-query-in-report-parameter-in-ssrs?forum=sqlreportingservices but that is not working for me. I tried to put 01 and 05 (no double
quotes) on different lines in the parameter available values expression box but I still get no results. My parameter is a data type of text and is not multi value.
If I change my available value to 01 I get correct results
I'm really stuck. I hope someone can help me.
Milissa Hartwell

Hi Milissa,
In order to achieve your requirement, I suggest that you should add another parameter named parameter1 in your report. For more details, please see:
Modify the query like below:
Select * from Table where column in (@Parameter1)
Add another parameter named Parameter1 with ‘Allow multiple values’ option in the report.
Select Hidden as the parameter visibility.
Specify the values below in the Available values:
Label: 1
Value: =iif(Parameters!Parameter.Value=1,”01”,”04”)
Label: 2
Value: =iif(Parameters!Parameter.Value=1,”05”,”06”)
Specify the values below as the Default Values:
Value: =iif(Parameters!Parameter.Value=1,”01”,”04”)
          =iif(Parameters!Parameter.Value=1,”05”,”06”)
Then when you select 1 as the choice of Parameter, it will directly affect the result into Select * from Table where column in (01, 05). When you select 2 as the choice of Parameter, it will directly affect the result into Select * from Table where column
in (04, 06).
If there are any other questions, please feel free to ask.

How to read the Key value from the Message using the text value.. Urgent

I need to read the Key valuefrom the message pool using the text value for the Key.. Is it possible.. Please help me with sample code..
Thanks and Regards
Avijit

Avijit,
I got your requirement. I really dont know the scenario your working on but its possible to do it. There is no direct way to do so, but complexity is in getting to know the Keys dynamically from interface.
Here you go..
     try
          Class msgClass      = IMessageTestWDApps.class;
//Replace IMessageTestWDApps with IMessage<Your WD Component name>
          Field keys[]      = msgClass.getFields();
          IWDTextAccessor textAccessor = wdComponentAPI.getTextAccessor();
          if(keys != null)
               String key = "";
               for(int index=0;index<keys.length;index++)
                    key = keys[index].getName();
                    wdComponentAPI.getMessageManager().reportSuccess("Key= "+key);
                    if(textAccessor.getText(key).equals("My message text"))

Generating next available Sales Order Number

Hi experts,
I have a requirement where i need to get to know the next available Sales Order Number in SAP for an SAP to third-party system integration scenario.
Is there any BAPI available which can list the next-available sales order number in the system?
Kindly share your expertise on this one.
Thanks in advance.
Regards,
Keerthi

Hi
You can use FM CVV8_GET_NEXT_NUMBER.
Provide Number range object as RV_BELEG.
To get the number range interval you have to pick value of NUMKI field from table TVAK according to your sales document type.
The function module will return the next available number.

Report Builder 3.0 and Report Parameters with Available Values - do a LIKE expression?

I would like to write an expression based on a @Status parameter that includes the labels you see in the diagram. My problem is that in the field Status - that includes these data results of Issued, Cancelled and Finaled - data entry is not consistent
so I would like to do a like expression for the value - something like this Issued would be "Is*" or Cancelled would be "can*" etc. however I keep getting error statements and I'm not sure what I'm doing wrong.

Hi KittyCat101,
If I understand correctly, you want to use a parameter to filter Status field that starts with “Is” or “Can” or “Fi”. If in this scenario, we can refer to the following steps to achieve your goal:
Modify the available values for @Status parameter to “Is”, “Can” and “Fi”.
Right-click the tablix or dataset to open the properties dialog box.
Select Filter in the left pane, then add a filter like below to filter Status field:
Expression: =Fields!Status.Value like (Parameters!Status.Value & "*") Type: Boolean
Operator: =
Value: true
If there are any other questions, please feel free to ask.
Thanks,

Getter/setter methods -- how do I use the return values

I'm just learning Java, and I haven't been to this site since the end of July, I think. I have a question regarding getter and setter methods. I switched to the book Head First Java after a poster here recommended it. I'm only about a hundred pages into the book, so the code I'm submitting here reflects that. It's the beginnings of a program I'd eventually like to complete that will take the entered information of my CD's and alphabetize them according to whatever criteria I (or any user for that matter) choose. I realize that this is just the very beginning, and I don't expect to have the complete program completed any time soon -- it's my long term goal, but I thought I could take what I'm learning in the book and put it to practical use as I go along (or at lest try to).
Yes I could have this already done it Excel, but where's the fun and challenge in that? :) Here's the code:
// This program allows the user to enter CD information - Artist name, album title, and year of release -- and then organizes it according the the user's choice according to the user's criteria -- either by artist name, then title, then year of release, or by any other order according to the user's choice.
//First, the class CDList is created, along with the necessary variables.
class CDList{
     private String artistName;//only one string for the artist name -- including spaces.
     private String albumTitle;//only one string the title name -- including spaces.
     private int yearOfRelease;
     private String recordLabel;
     public void setArtistName(String artist){
     artistName = artist;
     public void setAlbumTitle(String album){
     albumTitle = album;
     public void setYearOfRelease(int yor){
     yearOfRelease = yor;
     public void setLabel(String label){
     recordLabel = label;
     public String getArtistName(){
     return artistName;
     public String getAlbumTitle(){
     return albumTitle;
     public int getYearOfRelease(){
     return yearOfRelease;
    public String getLabel(){
    return recordLabel;
void printout () {
       System.out.println ("Artist Name: " + getArtistName());
       System.out.println ("Album Title: " + getAlbumTitle());
       System.out.println ("Year of Release: " + getYearOfRelease());
       System.out.println ("Record Label: " + getLabel());
       System.out.println ();
import static java.lang.System.out;
import java.util.Scanner;
class CDListTestDrive {
     public static void main( String[] args ) {
          Scanner s=new Scanner(System.in);
          CDList[] Record = new CDList[4];
          int x=0;
          while (x<4) {
          Record[x]=new CDList();
          out.println ("Artist Name: ");
          String artist = s.nextLine();
          Record[x].setArtistName(artist);
          out.println ("Album Title: ");
          String album = s.nextLine();
          Record[x].setAlbumTitle(album);
          out.println ("Year of Release: ");
          int yor= s.nextInt();
                s.nextLine();
          Record[x].setYearOfRelease(yor);
          out.println ("Record Label: ");
          String label = s.nextLine();
          Record[x].setLabel(label);
          System.out.println();

}//end class          First, I'd like to ask anyone out there to see if I could have written this any more efficiently, with the understanding that I'm only one hundred pages into the book, and I've only gotten as far as getter and setter methods, instance variables, objects and methods. The scanner feature I got from another book, but I abandoned it in favor of HFJ.
Secondly --
I'm confused about getter and setter methods -- I'd like someone to explain to me what they are used for exactly and the difference between the two. I have a general idea, that getters get a result from the method and setters set or maybe assign a value to variable. I submitted this code on another site, and one of the responders told me I wasn't using the returned values from the getter methods (he also told me about using a constructor method, but I haven't got that far in the book yet.). The program compiles and runs fine, but I can't seem to figure out how I'm not using the returned values from the getter methods. Please help and if you can explain in 'beginners terms,' with any code examples you think are appropriate. It will be greatly appreciated.
By the way, I'm not a professional programmer -- I'm learning Java because of the intellectual exercise and the fun of it. So please keep that in mind as well.

But this is something every new programmer goes through, and I will not spoil the fun. You see, in 3 to 6 months when you have learned much more Java, assuming you stick with it, you will look back at this and be like "what the hell was I thinking" and then realize just haw far you have come. So enjoy that moment and don't spoil it now by asking for what could have been better/ more efficient. If it works it works, just be happy it works.

So you are basically setting anyone up who responds to the post for a trap that could make them look bad when you double post.
You are setting you getters and setters up right as far as I can tell. Which tells me that I think you grasp that a getter lets another class get the variables data, and a setter lets another class set the data. One thing, be sure to use the full variable name so you should have setRecordLabel() and getRecodLabel() as opposed to setLabel() and getLabel(). Think about what happens if you go back and add a label field to the CDList class, bad things the way you have it currently. Sometimes shortcuts are not your friend.
And yes, you are using the getters all wrong since you are not saving off what they return, frankly I am suprised it compiles. It works because you don't really need to use the getters where you have them since the CDList Record (should be lowercase R by the way) object already knows the data and uses it in the printout() method. Basically what you are doing in lines like:
Record[x].getArtistName();is asking for the ArtistName in Record[x] and then getting the name and just dropping it on the floor. You need to store it in something if you want to keep it, like:
String artistName = Record[x].getArtistName();See how that works?
Hope this helped, keep up the good learning and good luck.

Ssrs parameter default value not showing ,when available values is binded to query dataset

I have developed a report using sql server data tools for vsiual studio2012 ,i have defined few parameters ,on one of the parameter when available values is binded to a dataset query, the report default value is not showing in report preview .
Many Thanks
Chandra

Hi Chandra,
According to your description, you have set the default value for a parameter, but it's not displayed when initially running the report. Right?
In this scenario, since you have set the available values bind to query, so your default values should be within these available values. If these default values are not within the available values, the default values will be not displayed. So please check
the default values.
Reference:

If you have any question, please feel free to ask.

Msql and o8i - using a default value in an insert

1. In an Oracle 8i Enterprise DB I have a primary key in table FOO called FOO_ID, it's SQL description is:
FOO_ID NUMBER DEFAULT TO_CHAR(sysdate, 'HH24MMSSMMDDYY') NOT NULL
1.5 I test via TOAD inserting a record into the DB without specifying FOO_ID, but specifying other values in the table row. I commit the data. When I commit the table correctly fills in FOO_ID with a time/date stamp per the above definition.
2. I run wtgpack and create an application which uses this table. I check the SQL code to make sure the column definition is copied to the snapshot which will be the basis for Oracle 9i Lite mobile DB on my laptop.
3. I run msync.exe and get the DB.
4. I run msql to make sure the data replicated ok. It did.
5. I run an INSERT statement not specifying a primary key hoping that the default will be used. For example,
"INSERT INTO FOO (FOO_TYPE) VALUES ('Test Type')";
I get the following error from msql:
[POL-3221] null key in primary index
The questions is, why isn't the O9iLite DB using the default value when creating the new record/row?
Thanks,
Z

Danny is spot on, but a little elaboration for the beginner:
childValue == "yes" asks whether these two are the exact same String object. There are times when that's true, but it's unlikely. Instead, use String equals() ( childValue.equals("yes") ) to ask whether the two have the same value.
With the simple class Danny suggests:
class Vessel {
   private boolean assessed;
   private int stenosis;
   public boolean isAssessed() { return assessed; }
}All you need in the loop is
Iterator vessels = vesselAssessed.values().iterator();
while (vessels.hasNext()) {
   Vessel vessel = (Vessel) vessels.next();
   if (vessel.isAssessed()) {
}

"The 'charCode' property of a keyup event should not be used. The value is meaningless." Is this possibly caused by a virus?

I don't know what's wrong with my Mac Mozilla Firefox, version 3.6.8, but today, it started alerting me about an error message on the "Error Console". In every website I visit, it tells me: "The 'charCode' property of a keyup event should not be used. The value is meaningless." Is this possibly caused by a virus?
I saw a pop-up which did not allow me to click it when I scatter the windows on my Mac. I was using Private Browsing, with pop-ups disabled, but one pop-up managed to get passed my settings, and open in another window. It would not allow me to select it, so all I did was to close Firefox, and start a new session. So far, everything has been normal, I also deleted the cookies it installed.
But, I still keep seeing that "Error Console" notice under my "Tools" on the Menu Bar, and when I clicked on it, it listed errors (such as what I listed above).
Would someone explain this to me?
Thanks for your help!

The messages you see in the Error Console are mostly to assist the web site's author in resolving compatibility problems. Some of them can assist you in determining why a web site doesn't work as intended. The one you mentioned doesn't sound that suspicious, except that it occurs on many sites. Perhaps one of your add-ons is trying to monitor what you type?
To diagnose whether this is caused by an add-on or one of your settings, you could try the following:
First, make a backup of your computer for safekeeping. To back up Firefox, see [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information].
Next, try starting Firefox in Firefox
[http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Be careful not to "reset" anything permanently if you didn't back up.
Does that resolve the errors? If so, then an add-on usually is the culprit. If not, try creating a new (blank) profile: [http://support.mozilla.com/kb/Managing+profiles Managing profiles].
If the new profile works correctly, you can choose between further research on your old profile or moving key settings like bookmarks from your old profile to the new one. [https://support.mozilla.com/en-US/kb/Recovering+important+data+from+an+old+profile Recovering important data from an old profile].
Hope this helps.

Is there a way to use a shortcut value in the page's header template ?

Hello everybody,
we would like to create a page template with centralized information in the database. I tried to use the shortcuts inside the page template, but it doesn't seems it's working, or I'm not using it correctly.
The only way I was able to use it is by using javascript to instanciate some properties, But I don't like that idea because it means I must edit all the page using that script. I simply want to change the page template and the changes be applied to all the page who are using that template.
Here is what I want to do :
<img src="#WORKSPACE#image/logo.png" alt='"MY_SHORTCUT"' />
IS there a way to have a dynamic substitution variables that I could use in my html object attributes ? (I'm using APEX 3.2)
Thank you

Shortcuts are not available for use in page templates. This is something of a pain.

IS there a way to have a dynamic substitution variables that I could use in my html object attributes ? (I'm using APEX 3.2)The closest equivalent to shortcuts in this case is probably an application item. Set the value using an application computation or process and reference it in the page template using static substitution syntax:
<a href="http://myserver.com/htmldb/f?p=100:1:415680519803489:::::" title="&APP_ITEM."> <img src="#WORKSPACE#image/logo.png" alt="&APP_ITEM." /> </a>Not sure that it's necessarily a good idea to use the same value for link <tt>title</tt> and image <tt>alt</tt> text in this case though. What value(s) will be used?

How to show the next available number to populate

I have a page which displays all of my columns.
My second column are numbers. If the 3rd column is filled in, the data on all of the columns will be displayed including the 2nd column on this page.
If the 3rd column is not filled in yet, only the next number of the 2nd column will be displayed somewhere on the page together with the rest of the data mentioned above. This number will be the next higher available number, or in other words, the next lowest number without something filled in for the 3rd column.
So when I click on this number, I can go to the next page to at least populate column 3. Thanks.

Let me see if I can explain better.
I have a table with all fields displayed including the edit icon on the left.
Let me see if I can illustrate this. Let the capital letters be columns of this table.
And let the data be as shown under the lettered columns. Here is a hypothetical sample of the data. The ...... is just to make the spacing happen for the columns to line up in this example
..... A B C D E.........F
edit 1 7 .c .d e 01-MAY-2008
edit 1 8 .c .d e 02-MAY-2008
edit....9...........-- would like to display this line
I would like to display the next available number for column B (in this case number 9 since it is after 8) for me to be able to edit by filling in data in the rest of the columns.
Now, for column B, I have number 9 all the way to say, 1000 available in the database but with no other data, just the number itself existing. Because these numbers (like 9) in column B have no data yet in colunm C, it will not be displayed in the table because there is no data to look at.
So after I can add data to column C and maybe other columns, then when I apply changes will #9 and its data show up in the table after data 8 and then #10 will show up as the next number available to receive data where 9 use to appear.
I hope this clarified it.
