Matching a list of characters

I'm trying to run a "SELECT" where I would match some characters in a sentence to find sentences with words starting in vogals.
Does Oracle have the ability to match strings with regular expressions?
So I would write something like
[aeiouAEIOU] and find these sentences.
null

You can use INSTR() function.
For example, if you are looking for a characters 'amjf' in a column col1, then your
select may look like
SELECT col1
FROM table_name
WHERE instr(col1,'amjf',1) > 0;

Is there a function to check a list of characters in a string?

is there a function to check a list of characters in a string?

You need to create a vi. Find attached a vi that you can use. In the vi, if the number of match occurrence is zero, that indicates no match otherwise it will return the number of matches in the supply string. The vi is a modified version of Search String and Replace - General

Match code list setting

Hello,
We have a specific match code list for a new field in the screen . We use Screen painter .
When we display match code it will be displayed by default a list ALV . But here How can we change to a list Basic for the values of this match code . ( SAP Basic list not ALV list)
Is there some way to change this setting for user ?
Thanks

Hi,
I already added the field search help into screen, But here user need to have basic list for search help ,( This search help is for KUNNR,Name1...etc, And they want to have basic list when they press F4 , not normally AVL liste

Regex to match numbers but not characters

Hey all,
I brain must not be working right or something but I cannot for the life of me figure out how to get a regex to match numbers, but not characters.
e.g.
123456
would match, but
123abc
would not. Essentially what I want to do is take a string and only return a match when the string has numbers but no characters.

No, it doesn'tYes it does.
"123abc".matches("\\d+");
"abc123".matches("\\d+");
"123".matches("\\d+");
false,false,trueExcellent example demonstrating the output of a method.
However the suggestion above was referring to a regular expression, not a method.
And the above regular expression does match with the following methods
"123abc".replaceAll("\\d+", "xxx");
"abc123".replaceAll("\\d+", "xxx");
"123".replaceAll("\\d+", "xxx");
The correct regular expression to match only digits is....
^\d+$

Java.lang.String: How can we replace the list of characters in a String?

String s = "abc$d!efg:i";
s = s.replace('=', ' ');
s = s.replace(':', ' ');
s = s.replace('$', ' ');
s = s.replace('!', ' ');
I want to check a list of illegal characters(Ex: $ = : ! ) present in the String 's' and replace all the occurance with empty space ' '
I feel difficult to follow the above code style.. Because, If list of illegal characters increased, need to add the code again to check & replace the respective illegal character.
Can we refactor the above code with any other simple way?
Is there any other way to use Map/Set in this above example?

RTFM
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
That document is almost perfectly useless for someone
who is just starting to learn regexes. What they
need is a good tutorial, and the best one I know of
for Java programmers is the one at
this site. When you're ready to move on from
introductory tutorials, get the latest edition of
Mastering Regular Expressions, by Jeffrey Friedl.Dear Uncle,
maybe you want to read that document first before judging its usefulness. And just in case you can't be bothered, the following is an exact quote, which accidently happens to clearly explain the op's question on the usage of \\[\\] in sabre's regex:
Backslashes, escapes, and quoting
The backslash character ('\') serves to introduce escaped constructs, as defined in the table above, as well as to quote characters that otherwise would be interpreted as unescaped constructs. Thus the expression \\ matches a single backslash and \{ matches a left brace.
It is an error to use a backslash prior to any alphabetic character that does not denote an escaped construct; these are reserved for future extensions to the regular-expression language. A backslash may be used prior to a non-alphabetic character regardless of whether that character is part of an unescaped construct.
Backslashes within string literals in Java source code are interpreted as required by the Java Language Specification as either Unicode escapes or other character escapes. It is therefore necessary to double backslashes in string literals that represent regular expressions to protect them from interpretation by the Java bytecode compiler. The string literal "\b", for example, matches a single backspace character when interpreted as a regular expression, while "\\b" matches a word boundary. The string literal "$hello$" is illegal and leads to a compile-time error; in order to match the string (hello) the string literal "\$hello\$" must be used.

Substring matching for lists

Can anyone suggest efficient data structure or algorithm to get the "subset" or "superset" of a string. What I mean by subset/superset is this:
"new york",
"new york city",
"new york state",
"york city"
superset("new york") = {"new york", "new york city", "new york state"} // left side is substring of every string on right side
subset("new york city") = {"new york", "new york city", "york city"} // every string on right side is substring of the left side
subset("new york state") = {"new york", "new york state"}The brute force way is use loop through each string and do string contains comparison but is there a more efficient method especially w/ith large string lists??

So if string A is a substring of string B than the subset of B contains A and the superset of A contains B.
A classical algorithm that is used sometime to speed substring searching works like this. You create an integer signature for each string. For example, you could set a bit in the integer to indicate the presence of each individual letter of the alphabet. (Since there are more letters than the 32 bit location, you would actually hash each individual letter to a number between 1 and 32 and set that bit). What the signatures do is let you do a very fast substring rejection. If the integer signature of A is NOT a subset of the signature of B it means that A has character that does not show up in B and thus A could NOT be a subset of B.
Note integer subset testing is very fast. A is subset of B iff (A & B) == A
More typically, this encoding is done not on letters themselves but rather on di-grams. So to encode "new york" you hash "ne", "ew", "w ", " y"...
Now, this structure, only gives you a fast reject. If signature of A really is a subset of signature of B it does NOT tell you that A is a substring of B. You must do the substring comparison to check, but it can reject lots of strings that could not possibly match quickly.
The use of 32 bits for the signature was arbitrary and may not be appropriate. If your strings are long, way more than 32 characters, you would find yourself in general setting most of the bits, and if most of the bits are set you will typically get no rejections. So you must choose the length of your signature to match the characteristics (average length) of the data you expect to be processing.
Thus to find the superset of String A, you would rip through the entire list of strings using the fast signature comparison to do a fast reject and only do the slower substring comparison on the ones where the signatures were compatible.
There is a sense in which this is still just the brute force method, in that you compare every string to every other string, but by preprocessing each string once to create a signature, you can potentially speed up all subsequent substring processing.
BTW I think Jos was pulling your leg about Patricia trees. They are a very efficient method for storing a dictionary of words that allow you to quickly decide if a word is in the dictionary but they are used for matching full strings against full strings, or full strings against prefixes and are not useful for matching substrings. Of course I could be wrong about this. I'd be happy to let Jos teach me a new use for Patricia trees.

SSRS and data from SharePoint lists - special characters in HTML

Hi All,
This may not actually fit into this forum, but here goes anyway...
We're using SSRS to report on data stored in Project Server workspaces (so SharePoint lists). Prior to upgrading to 2013, we could pull this data in and set the "Placeholder properties" of the text box to interpret HTML tags as styles and it would
format everything as it appeared in the SharePoint list. Now that we have upgraded to 2013, this works with a few notable exceptions - some special characters are rendered as their escaped/encoded (whatever the term is) - so a colon which is within the text
field in SharePoint, rather than appearing in the SSRS report as ":" appears as ":".
These are multiline, rich text formatted columns in the SharePoint list. Using =Replace(Fields!Description.Value,":",":") in the report makes the appropriate replacement, but given that this occurs with a handful of other special
characters as well, this solution becomes very unruley very quickly. Has anyone else encountered this, or does anyone have any other suggestions for a work around?
If not now, when?

Facing same issue but having no solution, please suggest..

SQL*Plus: list of characters that need to be escaped

Hi all,
We have a requirement where we need to add comments to tables and table columns and this is done using SQL*Plus. I understand that there are some special characters that are interpreted by SQL*Plus such as ampersand (&). I would like to know the list of such characters so that we can escape them before passing it on to CREATE COMMENT ON statement. So far we have identified the following special characters:
The following characters need to be escaped no matter where they are present in the comment
single quote "'" (hex 27)
define "&" (hex 26)
sqlterminator ";" (hex 3b)
The following characters need to be escaped when they are the only character on a line
forward slash "/" (hex 2f)
blockterminator "." (hex 2e)
sqlprefix "#" (hex 23)
The following characters need to escaped if they are followed by a newline
line continuation "-" (hex 2d)
We would like to know if there are other special characters and appreciate if someone can provide the list.
Thanks

I think the only two characters you need to worry about in your comment strings are: ' and & (apostrophe/single quote and ampersand). The latter you can get around by doing:
set define offbefore running your statements, but the apostrophe you'll have to double up to allow oracle to recognise that it's not the end of the string. Eg:
I'm a stringwould become
'I''m a string' -- NB. this is two single quotes, not 1 double quote!or, if you're on 10g or above, you can use the quote operator (q):
select q'#I'm a string#' from dual;See the documentation for what characters can be used as the quote delimiters: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14251/adfns_sqltypes.htm#sthref377

Instead of pointing to local files, re-matched library lists all local files as duplicates

I've got a mess. I moved my matched local music files from my internal drive to a larger external drive. I deleted the iTunes folder on the internal drive, created a new library by changing the location of my music library in iTunes preferences and adding all of the files on the external drive.
When I turned match back on, my cloud-based matched files no longer pointed to my local versions. Instead, match listed everything as a duplicate -- a copy in the cloud and a local copy even though the two copies are exactly the same, previously matched files.
I've added files to my cloud library from numerous computers -- so my cloud library is the most complete -- and I was in the process of creating one local, consolidated library on my new external drive by downloading those files from match. There has to be a way to re-sync both local and match libraries with everything matched as it previously was withouth having to either delete and re-upload or delete and re-download.
Any tips, instruction or help will be greatly apprieciated.

You didn't move the library in the right way. In the future, use this Apple KB article to move an iTunes Media folder: http://support.apple.com/kb/ht1449
To try to clean this up is going to take some work on your part but it isn't impossible. Start off with one album or artist at a time and delete them from the cloud. Then you should be able to select the corrosponding locally stored tracks, right click them, and choose "add to iCloud." This should re-initiate a scan on those tracks and add them to the cloud.

Custom Reports don't match Device List

Hi,
I have been trying to get a report from a cerain site that shows me to contain 545 devices (PC/Laptops).
When I create a report to give me a complete list of devices from that site I will get a total of 381. No matter how I try to tweak the custom report I don't get anywhere near the devices listed in the site.
Is there a known issue with reporting?
Is there anyother site I can check out for more info?
Server = ZENworks 10 Configuration Management with SP1 (10.1)
Client = 10.1.3
ThanX

I have yet to find a solution for my issue.
No matter how much i tweak my reports they never match the number of devices listed in a site.
Only sites that contain under 10 devices do the reports pull a proper number and match the number of devices.
Still no Luck.

Messages menu status does not match Buddy List window

Using Messages in Yosemite, the status of my logged-in buddies listed in the menu bar does not match the status of my buddies in the Buddies window. I have buddies listed in the window that are not in the menu bar and vice versa.
It seems that the menu bar list may not be updating correctly--when I try to message them, the chat window sometimes says they are "idle"

Hi,
Sending Feedback to Apple rarely (if ever) gets a response. At iChat 3 release with OSX 10.4 there was an issue that I gave feedback for.
I also happened to mention the issue in the Lounge Area for "New Technical Issues" and the Host linked to the iChat forums there were back then contacted me about it and had me run some stuff for Engineering. (that's a possible once in 10 years like you).
iChat 5 in Snow Leopard
The process on how to display a particular Set of Buddies is different (as you will see with the next pic)
However I only see those "Available" in a full sense in the Menu Drop Down.
Idle (Amber) is technically Available + (a second level of Available if you like)
Yosemite/Messages 8+ (Mavericks is also listed as Messages 8)
The whole thing as I have several Accounts Logged in does fill my screen top to bottom.
These pics agree with your first paragraph.
I will let my MacBook Pro go Idle as it has one Account in iChat there that is not on my iMac and see if the Menu Drop down changes when it does.
I will have to wait for this to happen.

My iTunes Match wish-list...

I stumbled across a page that Apple had up, asking for suggestions for Aperture. I don't know if there are different versions of iTunes Match, or upgrades coming. Apple engineers, if you're reading this I'd love to see the following in the next version of iTunes Match:
1. Update the playcount and "Last Played" dates when playing music that is streamed to an IOS device. That would be a nice feature
2. Sync additional playlists from iTunes to iTunes Match after the initial sync-match-upload. I have playlists that I've created after the intial sync and it would be great if we could get new playlists and music into the cloud. I've turned it off, turned it on. Updated iTunes Match a bunch of times. I wish there was some way to get it to show my current iTunes library.
3. When you buy an entire album from iTunes, it would be great to get the entire album into iTunes Match, not have some of the songs labled "Ineligible"
Those are three from my wish-list. Feel free to add onto it

There have been a number of posts about it, and it's affecting me as well (I also can't delete TV episodes) - I assume that there is bug with the current version of iTunes and/or a problem at Apple's end which they need to fix

Police route and match community-list

Hi All,
I have a C3825, and have been using standard ACLs and a PBR to route certain HTTP traffic via an alternative default gateway:
route-map RTRMAP-OfficeLAN permit 10
match ip address RTRMAP-OfficeLAN-toADSL
set ip next-hop x.x.x.x
This is working absolutely fine, and as expected, all traffic matching the ACL is being sent to x.x.x.x
However, we have recently expanded our network, and I am now receiving various networks via BGP from various sources. All BGP incoming via iBGP is tagged in communities:
Community (expanded) access list 100
    permit 37xxx:100
Community (expanded) access list 200
    permit 37xxx:200
Community (expanded) access list 300
    permit 37xxx:300
Community (expanded) access list 400
    permit 37xxx:400
Community (expanded) access list 500
    permit 37xxx:500
All communities are also matching prefixes when executing either 'sh ip bgp community 37xxx:100' or 'sh ip bgp community-list 100'
What I am trying to achieve, is create an EXCEPTION for the policy route. Traffic matching the community lists, must be forwarded based on the routers routing table, whilst traffic maching the ACL, must be sent via the policy route...
route-map RTRMAP-OfficeLAN permit 5
match community 100 200 300 400 500
route-map RTRMAP-OfficeLAN permit 10
match ip address RTRMAP-OfficeLAN-toADSL
set ip next-hop x.x.x.x
My logic dictates to me that the above should work, but looking at the route-map, I get matches on seq 5 and pacets are exiting the route-map as expected (first matched). However no traffic that does NOT match community 100,200,300,400 or 500 and that DOES match the RTRMAP-OfficeLAN-toADSL never matches.
The counters on the route-map for seq 5 is increasing, but no counters are increasing at seq 10.. It's almost as if seq 5 is matching all traffic.
Am I missing something?
Many thanks,
Chris.

Hi,
you can't use community-list for PBR afaik it only accepts ACLs for matching.

List of characters not supported for a field search of type char

Hi,
I have a field of type char.
When we create entries for that field in a table we use special characters like &, etc. When searched it is not supported and not displayed in results.
I suppose it might be because SAP can support for characters of specific ASCII codes.
If you have any list of the ASCII codes supported in search, kindly let me know.
Thanks and Regards,
Jaisish

Hi Jaisish,
as far as I know, there are two "special" characters that act as jokers in a field search
+: standing for one character
*: standing for zero or more characters
You can search for these characters into the content of a field, if you "escape" them. The symbol for escaping is "#" (before the special character + or *).
For example, if you search for "#*", this will search all entries with an asterisk in its content.
I hope this helps. Kind regards,
Alvaro

Match pattern and null characters

Hi,
I'm using LabView 2010 and want to write a VI that imports a spreadsheet file (txt) into an array, and then goes through the rows and looks for expressions.
Problem:
The "read from spreadsheet file" vi generates unnecessary spaces and empty rows and the data apparently contains null characters, so that the "match regular expression" vi returns only errors.
What is a null character and how do I get rid of it and how can I import the text file properly without the additional spaces and empty lines?
Thank you.
Original text file:
Text file imported into an array (note the spaces and empty rows):
vi:
Solved!
Go to Solution.

This file is not an ASCII text file but really an UTF16 file. As such the ASCII String to Spreadsheet file obviously has to run into problems trying to interpret it. A quick and dirty approach would be to read in the file as string first, remove the first two UTF16 file indication bytes and then remove every second character. If the file does only contain 7Bit ASCII characters you are all done and can feed the resulting string to Spreadsheet String to Array, otherwise you will get some strange characters at the positions that contain non 7Bit ASCII characters.
