Splitting a string -- 2 variables

I'm trying to split a string into 2 variables
One variable (exString) being a string, the other variable (exInt)integer
For example, I want to split JSPCool.006
the variables would contain:
exString = JSPCool
exInt = 006

Whoops. Sorry there's an error. Try this instead:
String var = "JSPCool.006";
int splitLocation = var.indexOf(".");
String exString = var.substring(0,splitLocation);
int exInt = Integer.parseInt(var.substring(splitLocation+1, var.length()));only problem is that number will not be left as 006....it will be converted to just 6.

How to Split the string using Substr and instr using loop condition

Hi every body,
I have below requirement.
I need to split the string and append with single quotes('') followed by , (comma) and reassign entire values into another variable. so that i can use it where clause of update statement
for example I am reciveing value as follows
ALN varchar2(2000):=(12ERE-3MT-4Y,4IT-5O-SD,OP-K5-456,P04-SFS9-098,90P-SSF-334,3434-KJ4-O28,AS3-SFS0-J33,989-3KL-3434);
Note: In the above variable i see 8 transactions, where as in real scenario i donot how many transaction i may recive.
after modification i need above transactions should in below format
ALTR Varchar2(2000):=('12ERE-3MT-4Y','4IT-5O-SD','OP-K5-456','P04-SFS9-098','90P-SSF-334','3434-KJ4-O28','AS3-SFS0-J33','989-3KL-3434');
kindly help how to use substr and instr in normal loop or for loop or while loop while modifying the above transactions.
Please help me to sort out this issue.
Many Thanks.

Try this - may not be the best way but...:
create or replace type myTableType as table of varchar2(255)
declare
v_array mytabletype;
v_new_str varchar2(4000);
function str2tbl
         (p_str   in varchar2,
          p_delim in varchar2 default '.')
         return      myTableType
    as
        l_str        long default p_str || p_delim;
         l_n        number;
         l_data     myTableType := myTabletype();
    begin
        loop
            l_n := instr( l_str, p_delim );
            exit when (nvl(l_n,0) = 0);
            l_data.extend;
            l_data( l_data.count ) := ltrim(rtrim(substr(l_str,1,l_n-1)));
            l_str := substr( l_str, l_n+length(p_delim) );
        end loop;
        return l_data;
   end;
begin
v_array := str2tbl ('12ERE-3MT-4Y,4IT-5O-SD,OP-K5-456,P04-SFS9-098,90P-SSF-334,3434-KJ4-O28,AS3-SFS0-J33,989-3KL-3434', ',');
      FOR i IN 1 .. v_array.COUNT LOOP

      END LOOP;
   dbms_output.put_line(RTRIM(v_new_str, ','));

How to split a string around "." expression

My code is:
public String removeExtn(String resource){
          String[] splittedName = resource.split(".");
System.out.println("LENGHT IS: "+ splittedName.length);
          if(splittedName.length >= 3)
               resource = splittedName[0]+ "." + splittedName[1];
          return resourceName;
     * @param args
     public static void main(String[] args) {
          Test obj = new Test();
          System.out.println(obj.removeExtn("myfile.xml.sample"));
But it doesn't split the string around "." and given the arraylength 0. But if I try to use any another character (e.g. "," or ";") it works perfectly fine.
Please help me.
Thanks in advance.

Hi mansi,
I had a same kind of problem a few days back.
What I learned was the split() method has a string expression in it, which is usually noted as regex .
'Regex' is just a short form for 'regular expression'
You may directly use the string variable you would split around in some cases or may want to use a '\\' before some of the characters.
I can't place whole information here .So, let me give you that sun site link I read it from.
This link deals with the whole string class.
You may want to ctrl+F and split to read on split method.
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.htmlThis link talks about the regular expressions
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html#sumI got his for you from that link :
\p{Punct} Punctuation: For One of !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~ This is for your knowledge.
And if you want a quick fix just for your code...
that'ld be using a
split(\p{.}) in place where u used a split(.)I have not tried that ...but u may want to!
Hope that helps.

How to split this string into 4 sections to a max 35 characters

Hello,
Does anyone have an idea how I can acheive this please.
I have this string
Expense_Inv_8- ExpenseInv_7- Exp001- Expense_Inv_6- Expense_Inv_5- Expense_Inv_4- Expense_Inv_3- Expense_Inv_2- Expense_inv1
and I need to display them in sections seperated by ';' as explained below
Section 1 Section 2 Section 3 Section 4
Expense_Inv_8- ExpenseInv_7- Exp001;Expense_Inv_6- Expense_Inv_5;Expense_Inv_4- Expense_Inv_3;Expense_Inv_2;
need to split this string into 4 sections seperated by ';' and each section should be of no more than 35 characters, if null should end ;;;
Section 1, 35 Character ended by;
Section 2, broken off after Expense_Inv_5 because Expense_Inv_4 will take it over 35 chracters)
Section 3, should only take Expense_Inv_4- Expense_Inv_3, because adding Expense_Inv_2 will take it over 35
characters, each record in the string is seperated by '-'
Section 4, dispays the reminder of the string

Hi,
Welcome to the forum!
Whenever you ask a question, it helps if you post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) and the results you want from that data.
I think I understand the problemk well enough to attempt a solution, but if the query below isn't right, please post that information.
WITH     cntr     AS
     SELECT     LEVEL     AS n

;As written, this requires SQL*Plus 9 (or higher). You can have multiple versions or SQL*Plus on the same client, if you really need to keep the older version.
:section_length is the maximum length of each section (35, as you stated the problem).
:section_cnt is the number of sections. In the query above, this is 4. If you change it, you not only have to change the bind variable, but you have to change the hard-coded SELECT clauses of the main query and the last sub-query (that is, got_pos).
MODEL or PL/SQL would probably be better ways to solve this problem.

Splitting a string in different substrings

Hallo,
I want to split a string of any length in new substrings and want to save these substrings in different variables.
I tried as following:
data:
      string type string value 'Hallo SAP world', "This could be any string with any lenght
      offset type i value 0,
      str_len type i,
      new_str type string.
str_len = strlen( string ).
do 5 times.
new_str = string+offset(3).
write : new_str.
write : ' '.
offset = offset + 3.
   enddo.
1_ Has anyone any idea, how to save the new substrings in different variables?
2_ Since the new substring has length 3. So how many times should the do-loop run?
Thanks
ama

Hi, Muhammed Aftab Alam
Test the following Sample code it working the same way you are requiring, I have Tested,
REPORT zfsl_sub_string.
DATA: main_string TYPE string,
      len_string TYPE i,
      reminder TYPE i,
      string_from TYPE i.
main_string = 'Hallo SAP World'. " You can give any string here.
len_string = STRLEN( main_string ).
DO 3 TIMES.
reminder = len_string MOD 3.
IF reminder NE 0.
    CONCATENATE main_string ' ' into main_string SEPARATED BY space.
len_string = strlen( main_string ).
ENDIF.
ENDDO.
len_string = len_string div 3.
string_from = 0.
DO len_string TIMES.
WRITE: / main_string+string_from(3).
ADD 3 TO : string_from.
ENDDO.
Following too the same as above just add PARAMETER for input String
REPORT zfsl_sub_string.
PARAMETERS: pstring TYPE string.
DATA: "pstring TYPE string,
      len_string TYPE i,
      reminder TYPE i,
      string_from TYPE i.
*pstring = 'Hallo SAP World'. " You can give any string here.
len_string = STRLEN( pstring ).
DO 3 TIMES.
reminder = len_string MOD 3.
IF reminder NE 0.
    CONCATENATE pstring ' ' into pstring SEPARATED BY space.
len_string = strlen( pstring ).
ENDIF.
ENDDO.
len_string = len_string div 3.
string_from = 0.
DO len_string TIMES.
WRITE: / pstring+string_from(3).
ADD 3 TO : string_from.
ENDDO.
Please Reply if any Problem,

Mapping issue: Split a string to multiple strings in an idoc

Hi,
I need to split a string with an undefined length into strings of 132 chars. The problem is, how to map from the source field to the target field,
which belong to an idoc segment. The segment has the occurence 1 to unbounded, and the field 0 to 1. Simplifying, i need to map one source field split it in 132
chars block and put the resultant blocks into an idoc field (maxLength = 132).
IDoc
Segment X
Segment (occurence 1..unbounded)
Field X
Source field SourceA (undefined length)----->-----Field TargetA (occurence 0..1) (maxLength = 132)
Segment Y

Ok...here is one way of achiving what u want - hope ur comfortable with working with context mapping...
Raise the context of ur source field one level higher and write a UDF funtionto do this -
Declare an array list
Read the source string and append it to the arraylist.
Then when u map ur target IDOC text...read from this array list and created ...By maintaining the context...there will be as many segments in the idocas there are in the arraylist..

How to split a string using IndexOf?

How would you split a string using indexOf and not using the .split method?
Any help is appreciated :D
Message was edited by:
billiejoe

would it be better to use the first or the second?
int indexOf(int ch)
Returns the index within this string of the first occurrence of the specified character.
int indexOf(int ch, int fromIndex)
Returns the index within this string of the first occurrence of the specified character, starting the search at the specified index.
I think the second would be helpful. so how do i read it?

How to split a string into tokens and iterate through the tokens

Guys,
I want to split a string like 'Value1#Value2' using the delimiter #.
I want the tokens to be populated in a array-like (or any other convenient structure) so that I can iterate through them in a stored procedure. (and not just print them out)
I got a function on this link,
http://www.orafaq.com/forum/t/11692/0/
which returns a VARRAY. Can anybody help me how to iterate over the VARRAY, or suggest a different alternative to the split please ?
Thanks.

How to create dynamic connection string with variables using ssis.

Hello,
Can anyone let me know on how to create dynamic connection string with variables using ssis?
Any help would be appreciated.

Hi vinay9738,
According to your description, you want to connect multiple database from multiple servers using dynamic connection.
If in this case, we can create a Table in our local database (whatever DB we want) and load all the connection strings. We can use Execute SQL Task to query all the connection strings and store the result-set in a variable of object type in SSIS package.
Then use ForEach Loop container to shred the content of the object variable and iterate through each of the connection strings. And then Place an Execute SQL task inside ForEach Loop container with the SQL statements we have to run in all the DB instances.
For more details, please refer to the following blog:
http://sql-developers.blogspot.kr/2010/07/dynamic-database-connection-using-ssis.html
If there are any other questions, please feel free to let me know.

OR ('|') in regular expressions (e.g. split a String into lines)

Which match gets used when you use OR ('|') to specify multiple possible matches in a regex, and there are multiple matches among the supplied patterns? The first one (in the order written) which matches? Or the one which matches the most characters?
To make this concrete, suppose that you want to split a String into lines, where the line delimiters are the same as the [line terminators used by Java regex|http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.html#lt] :
     A newline (line feed) character ('\n'),
     A carriage-return character followed immediately by a newline character ("\r\n"),
     A standalone carriage-return character ('\r'),
     A next-line character ('\u0085'),
     A line-separator character ('\u2028'), or
     A paragraph-separator character ('\u2029)
This problem has [been considered before|http://forums.sun.com/thread.jspa?forumID=4&threadID=464846] .
If we ignore the idiotic microsoft two char \r\n sequence, then no problem; the Java code would be:
String[] lines = s.split("[\\n\\r\\u0085\\u2028\\u2029]");How do we add support for \r\n? If we try
String[] lines = s.split("[\\n\\r\\u0085\\u2028\\u2029]|\\r\\n");which pattern of the compound (OR) regex gets used if both match? The
[\\n\\r\\u0085\\u2028\\u2029]or the
\\r\\n?
For instance, if the above code is called when
s = "a\r\nb";and if the first pattern
[\\n\\r\\u0085\\u2028\\u2029]is used for the match when the \r is encountered, then the tokens will be
"a", "", "b"
because there is an empty String between the \r and following \n. On the other hand, if the rule is use the pattern which matches the most characters, then the
\\r\\n
pattern will match that entire \r\n and the tokens will be
"a", "b"
which is what you want.
On my particular box, using jdk 1.6.0_17, if I run this code
String s = "a\r\nb";
String[] lines = s.split("[\\n\\r\\u0085\\u2028\\u2029]|\\r\\n");
System.out.print(lines.length + " lines: ");
for (String line : lines) System.out.print(" \"" + line + "\"");
System.out.println();
if (true) return;the answer that I get is
3 lines: "a" "" "b"So it seems like the first listed pattern is used, if it matches.
Therefore, to get the desired behavior, it seems like I should use
"\\r\\n|[\\n\\r\\u0085\\u2028\\u2029]"instead as the pattern, since that will ensure that the 2 char sequence is first tried for matches. Indeed, if change the above code to use this pattern, it generates the desired output
2 lines: "a" "b"But what has me worried is that I cannot find any documentation concerning this "first pattern of an OR" rule. This means that maybe the Java regex engine could change in the future, which is worrisome.
The only bulletproof way that I know of to do line splitting is the complicated regex
"(?:(?<=\\r)\\n)" + "|" + "(?:\\r(?!\\n))" + "|" + "(?:\\r\\n)" + "|" + "\\u0085" + "|" + "\\u2028" + "|" + "\\u2029"Here, I use negative lookbehind and lookahead in the first two patterns to guarantee that they never match on the end or start of a \r\n, but only on isolated \n and \r chars. Thus, no matter which order the patterns above are applied by the regex engine, it will work correctly. I also used non-capturing groups
(?:X)
to avoid memory wastage (since I am only interested in grouping, and not capturing).
Is the above complicated regex the only reliable way to do line splitting?

The longest match wins, normally. Except for alternation (or) as can be read from the innocent sentence
The Pattern engine performs traditional NFA-based matching with ordered alternation as occurs in Perl 5.

Can TestStand 2.0.1 store/compare strings (local variables, strings in *.ini files) as unicode strings?

Can TestStand 2.0.1 store/compare strings (local variables, e.t.c) as unicode strings? If so, how can I tune TS to do it? Is there built-in support for such strings in newer versions of TS? I've not found sufficient information on the matter at the DevZone Forums.

Hi Paul,
Try this example, I'm sure I downloaded this from NI website.
This just reads keys from an INI file but you can also write to an ini file by using the appropiate functions in the dll.
Hope this helps

How to split a string in jsp?

I have a set of strings or names in ${form.temp.name}Is there anyway I can split a string in jsp or jstl by a newline "\n" or space "\\s" character and print them separately. Or Do i have to do something in my controller as I am using spring with jsp and jstl for my web application?
Thanks.

Yes I did the work as below. When I use some delimiters like ";", the code works. But for the newline character of carriage return it does nto work.
<c:set var="str" value="${form.temp.name}"/>
                 <c:set var="delim" value=" \r\n|\\n"/>
                 <c:set var="array" value="${fn:split(str, delim)}"/>
                 <c:forEach var="token" items="${array}">
                     <p><c:out value="${token}"/> </p>
                 </c:forEach>                Icidentally for the same element, when I try to split in java with the same delimiters, it is working. I am surprised why it is not working?

Regex to split a String

Hi,
Here's a little regex problem Jos e-mailed me the other day, to which I didn't find a satisfactory answer (I found one, but it's rather verbose). Chances are that there is no short (or simple) solution, but when this is the case with a certain problem, I usually know why there is no simple solution because of some limitation with the regex flavor I am using. However, I can't think of one with this problem.
Also note that this problem can be easily (and far more efficiently) solved by writing a custom method, but I happen to like regex and am curious to know if there's some solution to this I missed.
So, without further a due, here is the questions:
Split a String T into parts with a maximum size N without splitting T on a certain sub string S. In other words: try to split a String in as large as possible parts (equal or less than N) without splitting it on a certain sub string.
You can use only one split(...) call!
Lets say S = abc and N = 5 then here are a couple of examples:
T            = xyabcdefgabc
T.split(...) = [xyabc, defg, abc]
T            = xyzabcbbzzzabcabcbcacbyyy
T.split(...) = [xyz, abcbb, zzz, abc, abcbc, acbyy, y]
T            = xyzzzzabcbabczabcabcabcacbyyy
T.split(...) = [xyzzz, zabcb, abcz, abc, abc, abcac, byyy]

Okay, I give up. I can see how to do this with find(), but not with split(). I hope you haven't been waiting for me all this time... :DTo be frank, yes I have. You, sabre and maybe Darryl (in a good mood ; )). Ah well, I am now convinced I didn't overlook some easy shortcut.
This is what I've cooked up:
class Main {
    public static void main(String[] args) {
        String[] tests = {"xyabcdefgabc", "xyzabcbbzzzabcabcbcacbyyy", "xyzzzzabcbabczabcabcabcacbyyy"};
        String sub = "abc";
        int max = 5;
        String regex = String.format("(?<=\\G.{%d,%d})(?=%s)|(?<=\\G.{%d})", max-sub.length()+1, max-1, sub, max);
        System.out.println("regex = "+regex+"\n");
        for(String test: tests) {
            System.out.println(test);
            System.out.println(" -> "+Arrays.toString(test.split(regex))+"\n");
}B.t.w. uncle_alice, this *\G* (previous match) functionality, is this some Java thing or does it exist in other regex flavors as well?
