  SQL: how to display the second string of the function in the Jobs table only if the function has more than one string.

  Hello

  You can use REGEXP_SUBSTR Oracle/PLSQL: REGEXP_SUBSTR function

  Select the function double REGEXP_SUBSTR('PUBLIC RELATION REPRESENTATIVE ','[^]+',1,2);

  Do you have any value of the column as no 2nd string?

• Combine two tables 1 d in a 2D array

  Hi all

  Maybe I forget what is obvious, but I can't find a solution to combine two tables 1 d in a 2D array AND (it is the impossible part for me) using the tables columns instead of lines.

  Example:

  Table 1:1, 2, 3, 4

  Table 2:5, 6, 7, 8

  Result: 1, 5

  2, 6

  3, 7

  4, 8

  The 'build array' function seems to add all tables as lines... I guess I could transpose the table, but I want it runs in a Subvi in constructions of different loop and I feel a little uncomfortable with it - I guess one would be left with a completely mixed table. I was maybe blind just to find the right function?

  Cheers, Jessi

  Hi Jessi,

  by default, LV is combining tables in rows. So when you need columns you must transpose the sets or use a different indexing scheme...

• How to fill a control ring with chains [] array?

  How to fill a control ring with chains [] array?

  It must be karma. (Try really bad karma because I couldn't post this question in my original)

  I must have been a Really bad guy in a previous life...  It's not like I'm bad in this one...

  So... what I want to do this time around?  Something that I thought would be easy... Well... it's a long story...  I had a simple solution, but the client wants something else.  -sigh-

  Here is what they want...  They want a control that allows for multiple selections to a control of the ring (or a control that allows a drop down selection menu).  Bites are filled at run time because it is based on 10 000 other precedents of things this particular choice.  So it must be dynamic.

  The snippet of code & images below show what I'm doing a little...

  The bottom image shows on the right bites which is filled in the control of the ring.  Since the number of items / items changes, I didn't have a bunch of controls stacked on another.  In addition, I have to deal with an unknown quantity of selections.

  Does anyone have a solution that can be recommended?  If so, can you share the solution / idea?

  Thank you

  I have posted a code that does something similar here: http://forums.ni.com/t5/LabVIEW/array-of-cluster/m-p/1822451#M625032

  It uses a table hint and individual controls that are moved on top of the table and populated as needed.  This approach might work for you?  You would need a two-column table and only control ring, which you would fill properly whenever the currently active cell changes.

• How to change the tab order of an array of clusters?

  How to change the tab order of an array of clusters?  I have the cluster arranged into a table in the front panel.   The element of the cluster passes horizontal and array element passes vertically.   When I press the tab key, the cursor will move to the item next to the table instead of the next item in the cluster (down to the place overall).

  so you have an array of clusters or cluster and the separate table?

  EXISTS checks for the existence of an element, not a value. Since you're using VARRAY (btw, it is not recommended), your only choice is a loop through:

  SQL> DECLARE
    2       TYPE dnames_var IS VARRAY(7) OF VARCHAR2(30);
    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');

    9            exit;

   12  END;

• Insert commas in a string

  Hello world

  I have a problem with a function that inserts commas in a string... and then I want a textfield to account for this string. The function is as follows:

          var count:Number = 0;
       var q2_Final:String;
       var tempString:String = "";
       var q2_UserInput:String;
          var q2_preCalc:Number;
          var q2_preCalc = 12345678*1000;
       q2_UserInput = String(q2_preCalc);
       
       for (var i:Number = q2_UserInput.length-1; i>=0; i--) {
            count++;
            tempString+=q2_UserInput.charAt(i);
            if ((count%3 == 0) && (i - 1 >= 0)) {
                 tempString+=",";
            }
       }
       
       for (var k:Number = tempString.length; k>=0; k--) {
       q2_Final+= tempString.charAt(k);
       }
  
          q2TextAns.text="US$ "+ q2_Final;
  

  The text which is showning the text field 'q2TextAns' when I run program is ' US$ null12, 345, 678, 000 ".

  Why I get the words "null" in front of my number? No idea on how to NOT to show the words "null".

  Thank you for your time,

  Rafa.

  because you are not initializing q2_Final.  use:

          var count:Number = 0;
       var q2_Final:String="";
       var tempString:String = "";
       var q2_UserInput:String;
          var q2_preCalc:Number;
          var q2_preCalc = 12345678*1000;
       q2_UserInput = String(q2_preCalc);
  
       for (var i:Number = q2_UserInput.length-1; i>=0; i--) {
            count++;
            tempString+=q2_UserInput.charAt(i);

            }
       }

• How to convert int to String

  How to convert int to String. I get the error 'cannot convert integer to int.

  Dim str As String = "abc";

  int NB = Integer.valueOf (str);

  Use Integar.parseInt (). But make sure your str contains the integer value (like str = '123') otherwise you will get the exception.

  String str = "123"; int num = Integer.parseInt(str);

• How insert/edit a table of contents in the Bookmap?

  Hi all

  I am quite puzzled, how to use a bookmap to create a full PDF with table of contents to FM9? Everyone (well almost...) wants to OCD but I found nothing in the help and did not try it myself. It seems that I would need to insert a table of contents in the frontmatter section.

  Please excuse if there is already a thread, a link would be useful I have search but can't find this problem in the forum. Maybe it's so simple that I'm the only guy to have problems.

  I also read in FM10 help but found nothing there either. All information is available from adobe at all? Update to FM10 would be an option if needed.

  Hi Robert...

  FM-DITA (any version) does not support the automatic generation of a table of contents, Index, etc. a bookmap book lists entry. To create a generated list, you must manually add this element in the generated directory file and regenerate your book. You'll want to do it anyway so that you can assign paging and numbering and apply special models. This procedure is still the best way to manage the map of generating the address of the DITA standard FM...

  http://KB.leximation.com/DFM/?kbid=4

  Other hand (here is the sales pitch)... If you use DITA-FMx, it is provided automatically. Once you have set up the INI file of book-building with the properties and characteristics in the book, lists of books that add you to the bookmap will become good listings and all your pagination and numbering is applied correctly (in addition to loads of other features).

• How insert/DML data in the table when the data in the related table changes

  Hello guys!
  
  I came across a problem that I need to get fixed. Because I don't know how to start and get it resolved I wanted to ask you for your expertise.
  
  The scenario is as follows:
  
  I have a table 'a' in my 10g database and a view "ab" which combined table 'a' with 'b' table in a view. However, the 'b' table is a table in another schema Manager database. and accessible (read only right) via a database link.
  
  Now here it is: whenever the data changes in table "b", for example 2 new sets of data is inserted, I need to insert automatically the 2 values of these 2 sets of data in my table "a". Same procedure for update and delete in table "b".
  
  The action that inserts data into the table 'a' must be initialized in my database, I have limited access to the other. Can I somehow use a trigger my reviews of "ab" to insert data into the table "a"? Or is it possible to use the "change notification procedure database" using the view as the reference?
  
  Desperately need help and example of all suspicion/code greatly appreciated. I am very new to Oracle and not very fond of PL/SQL routines. So please be so kind as to give me more details.
  
  Thanks in advance - I hope you have any ideas how I can get this problem resolved.
  
  Sebastian

  >

  ... it does not, since the DDL operations are not permitted on the remote databases (ORA-02021). I can't create the trigger on a view either. :-(
  So what ways are left to insert data into the table 'a' when the related table changes?

  Please, help if you have an idea!

  Yes,
  You can't perform the DDL (create the trigger...) on remote databases as you can see...
  Try to create this trigger in the local database that will make DML (insert into...) on the remote database.

      CREATE OR REPLACE TRIGGER local_forward_pt_after_insert
       AFTER INSERT
           ON N2K_INV_PT
           FOR EACH ROW
  
       BEGIN
           -- Insert records into table "a"
           INSERT INTO TBL_PUNKTDATEN@remote_database_sid
            ( INT_NUMMER,
              STR_GEBIET
               )
           VALUES
            ( :new.INT_INV_PT_NR,
              :new.GEBIET );

  I have a table 1 d I want to get into an Excel template.  How can I convert a 2D table so I can enter Excel Table.vi easy?

• How to add zeros to string in the table of the ADF

  I have af:table with a column that can have values such as "01", "STW", "RT003", etc., from the DB.

  I want to display the total length of 10 String with no leading zeros if the length is less than 10.  How can I do?

  I tried under expression groovy in VO and gives an error

  String.format("%10s", mycolumnname). Replace (' ', '0')

  Another option is to add an attribute derived from SQL in your VO, who gets the necessary column padded with zeros using built-in SQL Oracle LPAD function. For example, you can use the following SQL expression for the new attribute:

  LPAD (column_name, 10, '0')

  Another option is to add a transient attribute to your VO and specify an expression good Groovy for it, for example:

  (voAttrName is nothing)? ("NULL: String.format("%1\$10s ", voAttrName) .replace (' ', '0')

  Notice the backslash in front of the dollar sign. It is necessary to escape the dollar sign, which is a special character in Groovy.

  This approach is not good if the VO attribute value can contain spaces, as spaces of the value will be replaced by zeros too.

  Indeed a few questions:

  (1) I don't see what possible use of this part:

  -- DBMS_XMLGEN.setRowTag ( ctx IN ctxHandle, rowTag IN VARCHAR2);
  -- DBMS_XMLGEN.setRowSetTag ( ctx IN ctxHandle, rowSetTag IN VARCHAR2);
  -- the name of the table as specified in our DTD
  DBMS_XMLGEN.SETROWSETTAG(l_context_handle,'zipcode s');
  -- the name of the data set as specified in our DTD
  DBMS_xmlgen.setRowTag(l_context_handle,'mappings') ;
  

  (2) not really a problem, but do not use UTL_FILE to read XML files. Oracle already provides the practice of methods or procedures to read XML efficiently with an call (see examples below).

  (3) in order to use the DBMS_XMLSTORE, the names of XML elements must match the columns in the table exactly, which is not the case here. If you cannot change the structure of the XML or the structure of the table to get an exact match, you can pre-process the file (with XSLT, for example).

  So, below is an example of using DBMS_XMLSTORE and an alternative with XMLTable that offers more flexibility:

• How to name tables with variables (strings and integers)

  If I have berries in the program as

  M1, M2, M3, M4, M5,..., M20. And if I want to choose one of them at random, I have a way to loop in which there is a loop of research for the index number that is found in a table as M1 [1] = 1, M2 [1] = 2 and if I have a random number between 1 and 20, I can loop element tables [1].

  But y at - it another way with directly get the random matrix buy name. For example, I have the random number 14, which directs me to M14. How the name of the table to help me choose the M14 when I number 14...

  It is not clear why you need to do it this way, in particular there is no information on what values are other elements of the paintings.

  In general, there are several ways:

  1. you can have a table 2D - in this way, you need to separate tables and your first random number will choose the first dimension.

  2. you can place your berries in another table:

  var arrayOfArrays:Array = [M1, M2, M3,...];

  And extract them with random number. This is similar to the way 1 because you end up with table 2D anyway.

  3. you can create an object that has properties with the numbers and the values of these properties will be your berries:

  var arrayReferences:Object = {}

  A1: M1,.

  A2: M2.

  ....

  }

  Then you can get the berries with integer like this:

  trace (arrayReferences ["a" + 2]);

  Other means will involve several approaches to OBJECT-oriented programming.

  The last note, everything in AS3 is zero base (especially tables), so you better stick to it even in your naming conventions: M0, M1, etc...
