Check if a string is a number

• Check if the string is a number

  I need to check if a string is entered in a textinput control is not a number and do something. I tried
  
  If ((object.text is Number) == false) {}
  error = true;
  }
  
  But this does not work, I tried google, but didn't find anything useful.

  I think I'll go with the regex solution, even if it still does not work: s

  It always returns true even if it has an 'a' or so in it. It seems to only do that when the 'a' is NOT in front of the string.

  EDIT: found on google: var expression: RegExp = / ^ [0-9] + $/;

  Thank you for you answer and help me :)

• Check that a string contains data only numbers

  Hello

  I'm trying to find an elegant way to test an input string "serial number" format A00000000 (where A can be any letter and 0 can be a number any).  My first thought was to check the following features:

  (1) total string length = 9.

  (2) using the "Decimal String to the Number.vi", result = 0 (which indicates that the string contains no numbers).

  (3) using the 'Decimal string to Number.vi' with an offset of 1, the result is a number.

  Unfortunately, that does not differentiate between the following strings:

  A00005123 valid

  Invalid A5123

  Invalid A5123B123

  Invalid A005123BC

  All the world is this recently?  Is there a way to analyze non-specific chips (for example separating the groups of letters, numbers or other?)  Is there a complete way to do this without breaking the chain in 9 individual items and do a comparison of 26 item for the letter and 10 element for each number comparisons?

  Thank you

  Sean

  You can use a regular expression to match the pattern.

  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');

    5      for i in 1..dept_names.count loop
    6        if dept_names(i) = 'Shipping'
    7          then
    8            dbms_output.put_line('Exists ................');
    9            exit;
   10        end if;

   12  END;
   13  /
  Exists ................

  If you use the nested table, you can use MEMBER, SUMBULTISET, MULTISET EXCEPT:

    3       dept_names dnames_var := dnames_var('Shipping','Sales','Finance','Payroll');

  Hello Experts,

  Soon harry and thnaks in advance

  Harry,

  You can do this (and many other conversions from string to a number) with analysis of the chain. %x indicates LabView input data are hexagonal. There are also a lot of string functions to a number (for example ' in hexadecimal string to the number") which could be faster if you do this 100 000 times in loop, but analysis chain will solve 99% of your problems.

• How do I check the particluar string in the xml data

  Dear oracle Experts.
  I'm using the following oracle database.
  
  Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
  PL/SQL Release 10.2.0.4.0 - Production
  CORE 10.2.0.4.0 Production
  AMT for Linux: release 10.2.0.4.0 - Production
  NLSRTL Version 10.2.0.4.0 - Production
  
  I have a following xml data...
  p_msg_in CLOB: =.
  < DATA >
  < FLD FNR = DTE = '26 SEP 12' "ZZ0584" SRC = "DXB" OF the "DAC" = / >
  < AAA LBP = ETK '22334455' = ' 1234567/4' ACT = "123" / >
  < AAA LBP = ETK "223344" = "2345678/1" / >
  < AAA LBP = ETK "223344" = ' 1/123456' ACT = "345" / >
  < / DATA >
  
  then im go get the header like this information...
  
  v_msg_xml: = xmltype (p_msg_in);
  
  I'm IN multicur (v_msg_xml, ' / DATA/FLD ') LOOP
  V_1: = i.xml.extract('//@FNR').getstringval ();

  v_5: = i.xml.extract('//@SRC').getstringval ();
  v_6: = i.xml.extract('//@DES').getstringval ();
  END LOOP;
  
  After that, I need all the real records one by one, use it for a loop in a loop. Here for each iteration, I should check that a string of characters (for example law) is there or not. in the example above, 1.3 records have value of law in it. Well, I need to check something like that. If instr ("< AAA LBP = ETK"223344 "=" 123456/1 "ACT =" 345 "/ > ',' law") > 0 before performing the step below.
  How to get there.
  I appreciate your help.
  Thank you.
  C IN multicur (v_msg_xml, ' / DATA/AAA ') LOOP
  v_7: = c.xml.extract('//@LBP').getstringval ();
  v_8: = c.xml.extract('//@ETK').getstringval ();

  If I understood corrrectly you must give the LBP and values ETK tags AAA who attribute the Act. If so, all you need is:

  declare

• Check that a string is a string

  This may seem like a trivial question. I want to check that a string is a string. I thought to use a string method on a variable in a function and catch the exception. I did a little research around Java Platform SE 7. This seems to be a strange thing to do and I thought everything stable and if they fail, it must be a string, but I'd like something specific.

  832844 wrote:
  It's the thought. I wrote a recursive descent parser and verify a constant-> int | text | float

  Ah. So what you want is to find out if your string contains an integer, float or whatever.

  Assuming I'm right, and that the 'text' is equivalent to 'none of the above', can help the Java wrappers:

  public enum Type {INTEGER, FLOAT, TEXT);
  
  public boolean isType(String text, Type type) {
     try {
        switch (type) {
           case INTEGER:
              long i = Long.parseLong(text);
              break;
           case FLOAT:
              double d = Double.parseDouble(text);
              break;
           case TEXT:
              return true;
           default:
              throw new IllegalArgumentException();
        }
     } catch (Exeption) {
        return false;
     }
     return true;
  }
  

  Then just run above against all types except TEXT (or TEXT).

  It is likely to be slow, but its extensible for any type of "analysable" you want to check for, and you can do as specific as you want (the above example is rather crude).
  And I think that it is fairly easy to follow; at least I hope so.

• How a String get phone number?

  Hi all

  How a phone to get the string numbers. In this "Emp_Details" column, we have

  Phone number, address and Date. How we can get the only phone number.

  Example:

  Select Emp_Details from Table_name.

  Values of Emp_Details:

  13/01/2015

  AAA

  6617144613

  6617144613

  
  

  Please help me as soon as possible.
  

  Hello

  To find the rows where emp_details contains exactly 10 digits (and nothing else), you can use

  SELECT *- or what

  Table_name FROM

  WHERE the TRANSLATION (emp_details

  '123456789 '.

  ', ' 000000000 '.

  ) = "0000000000"

  ;

  I hope that answers your question.

  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.

  Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.

  If you change the query at all, post your modified version.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).
