Look at this SQLPLUS:
SQL> select regexp_replace('123abc', '[0-9]','') from dual;
REG
abc
SQL> select regexp_replace('1a7bc', '[0-9]','') from dual;
REG
abc
SQL> create table T ( Text varchar2(20));
Table created.
SQL> insert into T values ('12abc345');
1 row created.
SQL> insert into T values ('abc12345');
1 row created.
SQL> insert into T values ('123abc');
1 row created.
SQL> commit;
Commit complete.
SQL> select regexp_replace(Text, '[0-9]','') from T;
REGEXP_REPLACE(TEXT,'[0-9]','')
abc
abc
abc
IN OBIEE front end - Suppose in the column formual of column - Prod_desc - You have to use evaluate function - like this -
EVALUATE ('REGEXP_REPLACE(%1,%2,%3)',"PRODUCTS"."PROD_DESC",'[0-9]','')

Truncate numbers from string field

Afternoon all,
This time I'd like to extract only 2 strings out of a string field. The field is of sales area which contains numbers and letters. For example, Scotland is given a number 01, West midlands is 02, Ireland however is given IR.
however, the field which holds the information is like, 012, where 01 is the area number and 2 is type of area number.
The information which we are interested in is first two strings.
I have tried this in the formula given below but it doesn't work, it states a field is required
If hasvalue({?Sales Area}) then
totext(Minimum({slslsp.slr_slsperson}[1 to 2])) + " - " +
totext(Maximum({slslsp.slr_slsperson}[1 to 2]))
else
"n/a"
Should I be using a truncate and if yes then how?
P.S. This is to show only the sales area number or text if selected under a parameter. The values of the parameter will stay the same. In other words it is just to show in the report.
Many thanks once again
Regards
Jehanzeb

Is it a range parameter? If so try this
If hasvalue({?Sales Area}) then
totext(Minimum({slslsp.slr_slsperson})[1 to 2]) + " - " +
totext(Maximum({slslsp.slr_slsperson})[1 to 2])
else
"n/a"
regards,

Parsing multiple digit numbers from string

I have a string, specifically "Cups = 30" that I need to parse out "30" from. How can I do this? I've gone through tokenizing, it's dirivng me crazy!!

This program will help you
import java.util.*;
class s21
public static void main(String args[])
try
String s1="Cups=30";
StringTokenizer st=new StringTokenizer(s1,"=");
while(st.hasMoreTokens())
st.nextToken();
System.out.println(st.nextToken());//This statement will
give 30 as output
catch(Exception e)
System.out.println(e);

Extract numbers from mixed string.

How do I extract numbers from a mixed-character string?
These are house numbers and I have some exceptions - examples below.
How do I get rid of the letter/dash part, and keep the numeric part only?

It does not work if you have a string like 3343S##@1~!234

Urgent pl. I want to extract float from string (%f %s) or (%s %f) separate

I want to extract float from string (%f %s) or (%s %f) separated by tab, whitespace etc., Since I am using jdk1.3.1 I can't use regular expression can anybody suggest a simple (one or two or few line code - compact) to get the float in (sign+/-)#.#### format ignoring other characters ?
I tried:
e.g.,
String d="4.000 [tab]4";
source string resulted from "SUBSTRING query of mySQL" can be of :
" -4.543 XYZ ",
" XYZ -4.546 ",
" xx-yy 6.58 3 ",
"6.0 xxx yyy zzz",
the expected results for float from the string should be:
-4.543
-4.546
6.580
6.000
If String containing data separated by comma:
e.g.,
"4.120     1     ,
AAXXFE     ,4.206     1     ,
     4.000     1,
     4.201     1,
     4.189     1,
     4.204     1,
S     DDERSF-RSA"
The result should be: "4.120,4.206,4.000,4.201,4.189,4.204,0.000"
The string is created by:
ResultSet rs1 = stmt.executeQuery(S1);
while (rs1.next()) {
String d = rs1.getString("SUBSTRING(FIELD1,LOCATE(\""+s2[i]+"\",FIELD1)+"+ k_st + ","+ length+")");
System.out.print(d+",");
May be I don't know how to use the following:
float f1 = Float.parseFloat(d);
===
String pattern = "###.###";
//float value = -2100.578f;
DecimalFormat myFormatter = new DecimalFormat(pattern);
String output = myFormatter.format(d);
System.out.println(d+" " + pattern + " " + output);
===

Hi
You made the best choice. JRegex is closer to java.util.regex.* and fine works with excellent performance in any JVM version so you can use examples/tutorials from both JRegex and Java.Sun.Com to learn more about regular expression.
About the regular expression in my last post, there are two capturing groups: the first for float numbers in IEEE format specification (also see Java Language Specification) and the second for any sequence of chars, groups using with any amount of blank spaces (spaces, tabs, etc :: see regular expression definition) as delimiter. The anchors "^" and "$" are being used to exactly match pattern in target string and you can relax this constraint as needed.
How to use JRegex? no secrets!
import jregex.*;
// a float number and string with any blank delimiter
String patternString ="^([+-]?(?:\\d+(?:\\.\\d*)?|\\.\\d+)(?:[eE][+-]?\\d+)?)\s+(.*)$";
Pattern pattern = new Pattern(patternString); // different from Sun regex package syntax
// below is identical in both packages
Matcher m = pattern.matcher(anyTargetString);
if (m.matches()) {
Double d = Double.parseDouble( m.group(1) );
String scratch = m.group(2);
// your stuff goes here
..Remember to put JRegex jarfile in classpath!
Regards and Success.

Grabbing numbers from an array of type double and outputting them into a text file

In a program im creating i need to save some coordinates of a micropositioner i have into a text file,
I have the coordinates saved into an array that has 6 digits of precision (6 places after the decimal point).
I use the number to string conversion and wire that into the write to text file function in labview. When i open the file
the numbers that are only displayed are the ones to the left of the decimal point. I know the number to decimal string function
rounds the values so if i were to input 3.111111 it would only output the string "3" instead of "3.111111" .
So to get all the digits onto the file without rounding i multiplied the number by 10^6 but the decimal point will be lost at that point.
Is there anyway i can convert numbers into strings without labview rounding to the nearest whole number also without having to multiply by 10^6 and without having to expect the user to know that the coordinates saved in a file are multiplied by an order of magnitude of a million ?

ed oh i guess i just missed that function on the pallete after i saw that the function went from number to hex, octal, etc. i assumed that the rest on that row would be some sort of conversion to a different base number, haha thanks.

stored in xmltype table called bids
I want to run this query...
select extract(OBJECT_VALUE,'/bids/bid_tuple/itemno/text()').getnumberval() from bids;
it give me .. 1.0011E+63
Which I DO NOT NEED
I need numbers not string since extract or extract vlaue will return string AND using getNumberVal() will give me this strange result
I need it since I want to compare the result with data from relational table
Thanks

NinaOracle wrote:
select extract(OBJECT_VALUE,'/bids/bid_tuple/itemno/text()').getnumberval() from bids;That extracts and concatenates all itemno text nodes from the document into a single (possibly long) string.
With getNumberVal you then try to convert the string to a (possibly big) number, hence the display "issue".
If you want to break the XML into relational rows and columns, XMLTable is your choice :
SQL> SELECT x.itemno
2 FROM bids b,
3       XMLTable(
4        '/bids/bid_tuple/itemno'
5        passing b.object_value
6        columns
7         itemno number path '.'
8       ) x
9 ;
    ITEMNO
      1004
      1007
      1007
      1007

How to gather a set of floating point numbers from a web page form?

I am pretty new to Java and I am working on a project to apply Benfords law to find the probability of digits submitted by the user. My first step is to gather set of floating point numbers from a web page. How do I go about doing this? Any suggestion or a proper site where I can learn this stuff will be highly appreciated.

I am using NetBeans IDE 5.5.1 and for this project. I have realized that the first question was not well phrased.
I created a web project with 2 jsp files and a class file in it. When my jsp file runs I ask the user to enter a number for finding the probablility based on Benfords law.
This is what I got so far:
This is input.jsp
<h1></h1>
Please enter a number to be checked
<form action="result.jsp" method="post">
<input type="number" name="number" >
<input type="submit" value="Check number">
</form>
</body>
</html>
This is result.jsp
String number=request.getParameter("number");

More efficient way to extract number from string

Hello guys,
I am using this Regexp to extract numbers from a string, and I doubt that there is a more efficient way to get this done:
SELECT regexp_replace (regexp_replace ( REGEXp_REPLACE (' !@#$%^&*()_+= '' + 00 SDFKA 324 000 8702 234 | " ' , '[[:punct:]]',''), '[[:space:]]',''), '[[:alpha:]]','') FROM dual
{code}
Is there a more efficient way to get this done ?
Regards,
Fateh

Or, with less writing, using Perl syntax \D (non-digit):
SELECT regexp_replace(' !@#$%^&*()_+= '' + 00 SDFKA 324 000 8702 234 | " ','\D')
FROM dual
REGEXP_REPLACE(
003240008702234

Convert from String to float

How do I convert from String to float?

Hi,
you can use a Double for example - assuming value is that string to parse
float f;
try { Double d = new Double(value); f = d.floatValue(); }
catch (NumberFormatException e) { f = 0.0; } // error - string value could not be parsed
// here use your float fHope, that helps
greetings Marsian
P.S.: the Double class is usefull for that, because you also can get intValue(), doubleValue() or longValue() out of it for example. The StreamTokenizer for example parses numbers also only to double.

How do I avoid Error 85 in Scan From String scanning VISA read buffer?

I have encountered an Error 85 with my Scan From String VI. I have a timed
loop to read data from a device (flowmeter) using a serial port. This device takes
periodic measurements and sends the reading which contains a numerical value to the serial port COM1. It cannot be read continuously, and the period
between measurements may vary, so I decided a timed loop would be better than a while loop.
The VI begins with VISA Configure Serial Port and then
goes to a VISA Write which sends the message to the device to begin
taking measurements. After this, the device usually says "TAKE FLOWMETER READINGS" to the terminal, thereafter only sending numbers. Then begins my timed loop containing VISA Read. I
am taking the read buffer two places.
First, I am taking it to an Array to Spreadsheet String with the
Format String %.3f, as was in the Write to Text File example. Then I am
using Concatenate Strings with this string and also a string containing
the System Time. This string goes to Write to Text File, which I have
configured using Open/Create/Replace File outside of the loop.
Second, I am taking the read buffer to a waveform chart. I thought
it would be a good idea to use Scan From String to convert the string
into a DBL which I am then sending to the waveform
chart.
I am not sure if the initial "TAKE READINGS" message is giving me an error. I was able to get one reading saved to my text file from the device.
Also the format string for my Scan From String is %.3f
I am getting the Error 85 at the Scan From String only sometimes.
When this happens, there is no data being written to the text file. But
other times, I get data and it writes to the text file just fine (but
rounds to nearest whole number).
Any help would be greatly appreciated! This serial port device has been giving me a lot of trouble.

Is this what you mean? Did I wire the shift registers correctly?
I didn't know if you meant to Concatenate before Scan From String or Concantenate before or after VISA Read?

Cut text from string

Hello. Is there any way I can cut text from string?
I have responseResult variable which has value: {"success":true,"error":"No any errors."}
I want >>No any errors. << text from that string variable.

Like Varun suggested above, this text is JSON, and you can parse out the various values using JSON deserialising.
If you just want to use standard string manipulation (which I wouldn't recommend unless this is the only string you want to 'cut up') you can use various combinations of string functions.
For example, you could split the string at every double-quote mark:
string jsonString = "{\"success\":true,\"error\":\"No any errors.\"}"; // initial string
string[] strParts = jsonString.Split('\"'); // split string into an array of parts of the original separated at each double quote symbol
string partINeed = strParts[5]; // get the specific part needed
That's not a good way to do this in general (you should add proper JSON parsing), but for a single use it's OK. Note that you have to hard-code which piece of the string you're getting, which is not a safe approach.
Also note I used "\" in those strings so I could incorporate double-quotes in the string.
For more detailed string manipulation read up on RegEx. If you need to parse a lot of these strings in your app use JSON.
I'm a self-taught noob amateur. Please take this into account when responding to my posts or when taking advice from me.
Thank you guys. That solved my problem.

Parsing from string to int

in my C# project I have an array type of String. the array gets numbers from type int.
int numCell;
string[] arr = new string[numCell];
then i use it in a function like this:
sum += int.Parse(arr[i]);
and it works!
but, when i dothe same thing in WPF it tells me:
Input string was not in a correct format.
what shouuld i do?

Why did you mark your own question as answer? Please unmark it.
>>if in C# it worked why wouldn't it work in wpf?
As I have already mentioned, it is because of the actual value of arr[i]. It has nothing to do with Windows Forms or WPF but it is possible that your WPF application has put a different value in the array than your Windows Forms Application did. And if this
specific value is not a valid number the parsing will always fail. So you should check the values that put into the array and probably use the int.TryParse method to do the parsing:
int sum;
if (!int.TryParse(arr[i], out sum))
//the value of arr[i] was NOT a valid number...
This will however not change the fact that for example the value "D1" cannot be converted to an int using the int.Parse or int.TryParse method.
Please remember to close your threads by marking helpful posts as answer and please start a new thread if you have a new question.

Scan from string in pda

Hello.
I work with LV 7.1, with the I Modul of PDA.
It doesn't work me 'Scan From String'. I have not found any contradiction because the pda doesn't accept it.
Does somebody know which the cause can be? As I can substitute it?
Thank you.

scan from string.JPG ‏6 KB

Hello Greta
The Scan from string function is supported in LV PDA but with some restrictions. The help file for LV PDA tells us:
'The Format Into String function and the Scan From String function do not support changing the numeric separator (such as %#;). The Scan From String function does not support wildcard matches.'
You are changing the numeric separator and this is not supported.
Hope this helps
