Compare and extract number from string

Hi, all
If I want to compare a requirement number and extract a number form a continuous data, . for example,
the string like this ( ******** 123 ******
*********456 ******
*********789*******)
and I have requiremnts that I need to extract the number is nearest greater 450, so in the above example, I need to pick 456.
How can I result it?
thanks

Just extract all numbers into an array, then find the element with the smallest absolute difference. See attached (LabVIEW 7.0).
EDIT: Sorry, If by "Nearest greater" you mean the next higher number, you can use something like in my example II. (Also LabVIEW 7.0).
If you don't recognize an node, just right-click on it and select help.
You still need to add proper execption handling, e.g.:
What if no element is greater?
What if there are multiple solutions?
What if the string does not contain any numbers?

Hyperion Brio: Computed Item Extract Number From String

I would like to extract a number from a string in a computer item. For example if I had a string such as "The customer purchased $5.00 of footballs", I would like to remove only the 5.00 from the string. I would have to use the java functions in the results. Any suggestions on how to do this?

you can do this in the Results section with a computed column using the native string functions. to break it down i have split it up a bit.
strval is you string "The customer purchased $5.00 of footballs"
position of $ = 25
     Instr ( strval, '$', 1, 1 )
the starting position of the amount would then be 26
     Instr ( strval, '$', 1, 1 ) + 1
position of decimal after $ = 26
     Instr ( strval, '.', Instr ( strval, '$', 1, 1 ), 1 )
using Substr function you need to pick the string, the start value and the number of characters.
string
     = strval
start position
     = Instr ( strval, '$', 1, 1 ) + 1
number of characters - location of decimal minus the start position plus 3 to get the cents
     = Instr ( strval, '.', Instr ( strval, '$', 1, 1 ), 1 ) - Instr ( strval, '$', 1, 1 ) + 3
put all together
Substr( strval, Instr ( strval, '$', 1, 1 ) + 1, Instr ( strval, '.', Instr ( strval, '$', 1, 1 ), 1 ) - Instr ( strval, '$', 1, 1 ) + 3 ) * 1
the multiply by 1 converts the string to 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
SQL>
{code}

Extract Number from string

I need to extract the number, if it exists, from an alphanumeric text string. I am told that the first two characters will be alpha and the remaining character(s) will be numeric, if the numeric exists at all.
I know this is a simple formula, but I can't quite get it.

Are the two alpha and remaining numeric characters always in the same position within the string?
Are the two alpha characters always going to be the same?
Is the length of the numeric value following the two alpha characters always going to be the same?
The more no answers you have to the above the tougher it will be!
Get back with the above answers and possibly copy and paste some examples of the ENTIRE strings from which you will be extracting the values and let us know which are the values you'll be pulling from within the larger string.
"I need to extract the number, if it exists, from an alphanumeric text string. I am told that the first two characters will be alpha and the remaining character(s) will be numeric, if the numeric exists at all.

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.

Fetch Sales order number and PO number from ship to party and sold to party

HI,
I need to get Sales order number and PO number
from ship to party and sold to party.
I have only ______sold to party and ship to party and req del date_______ in selection screen as mandatory
Please let me know
Sreekanth

Hi,
You can do this:-
SELECT VBELN FROM LIKP
INTO TABLE T_DELIVERIES
WHERE KUNNR = SHIP TO PARTY
AND     KUNAG = SOLD TO PARTY
AND LFDAT      = DEL DATE.
You will get a table containing the list of deliveries.
Use VBFA to get the sales orders from deliveries.
SELECT VBELV FROM VBFA
INTO TABLE T_SALESORDERS
WHERE VBTYP_N = 'J'
AND     VBELN = T_DELIVERIES-VBELN.
T_SALESORDERS WILL give you list of sales orders.
From Sales Orders you can get Purchase orders through EKKN Table.
Using EKKN pass T_SALESORDERS-VBELN and get corresponding EBELN.

(street name are 90% char, number is 100 numeric, in 10% street name name

Hi,
Solution of Mr. Wijk come first, however I like to post (it's very similar and incomplete, I know...). Supose you have a table call address (use position -1 like Mr. Wijk to look backward). It's better in cases like '1.My Street 123' (the space before the number is very important)
SELECT substr(a.street_name,
              1,
              instr(a.street_name,
                    -1) - 1) street_name,
       substr(a.street_name,
              instr(a.street_name,
                    -1) + 1) street_number
FROM address a;Regards,

How to get Storage unit and Warehouse number from Handling Unit.

hello all,
I have Handling unit and Material in my program as an input, using these two fields i have to get corresponding storage unit and ware house number, to pick up transfer order.
Can anybody explain me who can we get Storage Unit and Warehouse Number from Handling Unit.
I know we can pull transfer order from table LTAK & LTAP using warehouse number.
But i dont understand how to get warehouse number from handling unit.
There is table LSUTO which has warehouse and Handling unit relation, but in our system there is not data maintained in that table. So, i was just wondering how can i get warehouse number from the given handling unit number.
please guide me
thanks
Edited by: Mr A on May 12, 2008 1:23 AM

Hi ,
Check out the handling unit item table VEPO. You got storage location(LGORT) in it.
Reward points if it was useful.

Want to crop an image of car and extract number plate from it.

i have a problem in my project.I have to crop the edges of a car's image and i want to extract only it's number plate.The OCR i am using can not extract charcters which are skewed etc.Can i have a code through which i can crop an image and extract only specific part?

Is this a college project ?
Cos it sounds extremely tricky to attempt.
If I was attempting this I might
1. Assume a fixed camera position.
So that I'd know what the road looked like without any cars.
Take a photo of this road as a "control background".
2. Assume a standard number plate system.
In Ireland, they've a white background, black lettering.
No italic writing.
Then, when I detect a car ( say more than 5% of the "control background" is covered ), I might try searching for the black & white lettering.
This might involve scanning the image from left to right, top to bottom, and defining rectangular ranges of black & white pixels.
( I'd allow multiple regions, so there could be more than 1 plate in the photo.
It might even pick up sign-writing on vans and cars ! )
That's just my initial quick idea of how to attempt it.
Could be easier ways...

Owen

Validating and Extracting Data from OBSSOCookie

Hello, I am looking for references on how to validate an OBSSO Cookie that is presented by a user (through their browser) and how to extract values from the cookie (using JAVA API calls in the Access Manager SDK).
I am not able to locate any references in the developers guide - can someone please assist or point me to some documentation to start?
Thanks in Advance.

Here's a snippet from when I did this to get the username from the cookie:
public String getUser(HttpServletRequest request, HttpServletResponse response) {
try {
String sdkLocation = System.getProperty("oam.sdk.location");
ObConfig.initialize(sdkLocation);
catch (ObAccessException ie) {
System.out.println("Initialize failed");
ie.printStackTrace();
Cookie cookie = getCookie(request, "ObSSOCookie");
ObUserSession userSession = null;
try {
userSession = new ObUserSession(cookie.getValue());
catch (Throwable t) {
t.printStackTrace();
System.out.println("Failed to create new user session");
try {
String DNarray[];
if (userSession.getStatus() == ObUserSession.LOGGEDIN) {
String userDN = userSession.getUserIdentity();
StringTokenizer userST = new StringTokenizer(userDN,",=");
DNarray = new String[userST.countTokens()];
for(int i=0;userST.hasMoreTokens();i++){
DNarray[i] = userST.nextToken();
userID = DNarray[1];
System.out.println("user ID is " + userID);
else {
System.out.println("Login failed. Return status = " + userSession.getStatus());
catch (com.oblix.access.ObAccessException obae) {
obae.printStackTrace();
obae.getMessage();
return userID;
}

Extract date from string in T-SQL

Hi,
I am having one field(AT_TEXT) in my database that has below kind of values. I want to extract date from this string but the issue is all rows has different format.
1)One Month Lttr sent on 3/12/2009 due to
2)One Month Letter sent on 1/15/2009 due to
3)One Month letter sent on7/15/2011.The amount due - This has no space between on and 7 and . after yr
4)One Month letter sent on 7/16/12 due to - This has 12 instead of 2012(2 positions after 2nd slash/)
Can anyone please help me to write query to extract date from this string?
Vicky

Hi Jingyang
Li,
I checked your query and it looks good but I have one issue. So when we reverse it, it looks like below and it is talking that $57.80 as a 1st numeric value and try to convert it into date and giving me error.
I realize from your query that you are trying to reverse the value and then try to find out 1st Numeric value from that string, but my whole string has another numeric value at the end, like
"One Month Letter on 1/15/2009 due to non-pmt of prems-amt to avoid DE is $57.80"
So when we reverse it, it looks like below and it is taking that $57.80 as a 1st numeric value and try to convert it into date and giving me error.
"08.75$ si ED diova ot eud tma - smerp fo tmp-non ot eud 9002/51/1 no retteL htnoM enO"
Also sometimes I have $ amount at the end and sometimes I don't have any $ amount at the end, like below,
"One Month letter sent on 10/15/2012 due to non-payment of premiums. The amount due to avoid dise"
Can you please modify your query which takes only date part not the $ amount and give me?
Thank you so much for your help
Vicky
