Use of special characters in Search String

What is the use of special charaters like
in the search string in the Find & Replace of ABAP editor ?
I want to search for all strings starting with V which are followed by alphabets like
VA
VB...
If I use V*, it also gives me results like
V/R...
Whether it is possible to specify such a condition?

Hi,
While giving ur search in FIND & REPLACE,
use the match case or match whole word only..
Then u will get search results only where the exact case of that variable is used..
As per my knowledge there is no signification of special characters ,- : ; in the search string..
Hope this helps...
Cheers,
Simha.

How to search special characters in a string

Hi all,
I want to search special characters in all string columns and all rows in the table.
The table has about 5 string columns and about 5.000.000 rows. For each row and column, I have to search entries, which included special characters like ", !, ? or something else (f.ex. "Mama?Mia" or "!!!Hotel out of order!!!"). The problem, the character could stand at each position in the string.
What's the best and most performance possibility to search such entries?? Is it possibility only by SQL; is there a special function for this?? Or must I use PL/SQL.
Thanks for helping

RegExp for excluding special characters in a string.

Hi All,
Im using Flex RegExpValidator. Can anyone suggest me the correct expression to validate this condition?....
I have tried this expression :----- /^[^///\/</>/?/*&]+$/...But in this it is also negating the alphabets.Also I have tried with opposite condition that in the String we should have alphabets and the expression is:-- ([a-z]|[A-Z]|[0-9]|[ ]|[-]|[_])*..... Please can anyone help me on this.
Thanks in advanced to all.

Re: RegExp for excluding special characters in a string.
here is a sample app taken from the live docs
using ^[a-zA-Z0-9 \-_]*$ as the regex accepts all characters from a-z, A-Z, 0-9 - [space] and_
run the example tell me what regex you are using and what test strings fail when they should pass or pass when they should fail

Special characters in search criteria

Hi gurus.
Can anyone tell me something about usage special characters in search cryteria (e.g. in transaction CN43N field POSID - I'm looking for some WBSs). I have try to find answer, but I'm not able to. I know about characters + and * , but I wonder are there any more. If yes, please tell me what do they mean

PDS - XML format, unable to read special characters in a string.

Hi All,
I've been using XML files to create my report with Oracle9i's new featue of PDS.
Now, I'm unable to read a file if it contains '&' or '<' in the string. In fact, the xml file itself not able to crate a xml page in the browser, if these special characters are present.
Is there any way to solve this problem ?
I can't tell the users to remove &, < from the description data. Is there any way to workaround for this ?
Thanks in advance,
Satya.

Hi Rohit and Rajesh
Thanks for your reply.
In fact, my problem is like this:
I'll get data in .txt file and save that as a .xml file in the network before calling Oracle report ,which gets data from the .xml.
The contents are like this:
<Comapy name> Ford Motors UK & Europe</Company name>
<Department> HR & Pensions</Depatrment>
<Salary>Grad4 < 25000 </Salary>
As per XML entity character representation, I need to replace '&' with '&' and '<' with '<lt;'
I'm wondering is there any other way to solve this problem as it is difficult to replace '<' and '>' generically.
Honestly, I couldn't understand what Mr. Rajesh was trying to tell.
'for & use & ( with semicolon at the end)'
'for < use <'
'for > use >'
Can you shed some light on this ?
Many thanks
Satya.

Replace all special characters in a String with underscore

I have a String which contains some special characters even(!,$,@,*....).
I need to replace all the special characters with _ in my String. I do have an idea of using String.replace() and analogous forms, but I would be thankful if anyone can suggest me of a better and an efficient way.
regards,
fun_one

Kaj,
Thx for your earnest reply. I did have a peep into the API on this method. But the regular expression that I need to use here was beyond my understanding. It did specify some regex that I put to use (something like myString("\D","_"), assuming that I need to replace all non-digit characters ), but it really did not help me getting the result.
Would you spare some code for me reg. the usage of regular expressions in such a scenario?

Check special characters in a string

Hi all
I am using oracle 10g.......
Need to know what should be the query to check whether a special character exists or not in a column value....used the following query like.....
select count(*) into emp_no_count_special_char
from dual
where REGEXP_LIKE(insert_data_rec.emp_no , '[#!$^&*%./\|]$' )
or REGEXP_LIKE(insert_data_rec.emp_no , '^[#!$^&*%./\|]' );
This works fine in case a string starts or ends with a special character ,what if a string of special characters lies in between numeric digits.
e.g: '100#$%7'
Please help find a query that checks for the existence of sp. characters irrespective of their position in the column!!!
Thanks
Dave

WHERE REGEXP_LIKE (insert_data_rec.emp_no, '[#!$^&*%./\|]');
-- Check that no special characters exist in the string

How is it possible to use Index Seek for LIKE %search-string% case?

Hello,
I have the following SP:
CREATE PROCEDURE dbo.USP_SAMPLE_PROCEDURE(@Beginning nvarchar(15))
AS
SELECT * FROM HumanResources.Employee
WHERE NationalIDNumber LIKE @Beginning + N'%';
GO
If I run the sp first time with param: N'94', then the following plan is generated and added to the cache:
SQL Server "sniffs" the input value (94) when compiling the query. So for this param using Index Seek for AK_Employee_NationalIDNumber index will be the best option. On the other hand, the query plan should be generic enough to be able to handle
any values specified in the @Beginning param.
If I call the sp with @Beginning =N'%94':
EXEC dbo.USP_SAMPLE_PROCEDURE N'%94'
I see the same execution plan as above. The question is how is it possible to reuse this execution plan in this case? To be more precise, how
Index Seek can be used in case LIKE %search-string% case. I expected that
ONLY Index Scan operation can be used here.
Alexey

The key is that the index seek operator includes both seek (greater than and less than) and a predicate (LIKE). With the leading wildcard, the seek is effectively returning all rows just like a scan and the filter returns only rows matching
the LIKE expression.
Do you want to say that in case of leading wildcard, expressions Expr1007 and Expr1008 (see image below) calculated such a way that
Seek Predicates retrieve all rows from the index. And only
Predicate does the real job by taking only rows matching the Like expression? If this is the case, then it explains how
Index Seek can be used to resolve such queries: LIKE N'%94'.
However, it leads me to another question: Since
Index Seek in
this particular case scans
all the rows, what is the difference between
Index Seek and Index Scan?
According to
MSDN:
The Index Seek operator uses the seeking ability of indexes to retrieve rows from a nonclustered index.
The storage engine uses the index to process
only those rows that satisfy the SEEK:() predicate. It optionally may include a WHERE:() predicate, which the storage engine will evaluate against all rows that satisfy the SEEK:() predicate (it does not use the indexes to do this).
The Index Scan operator retrieves
all rows from the nonclustered index specified in the Argument column. If an optional WHERE:() predicate appears in the Argument column, only those rows that satisfy the predicate are returned.
It seems like Index Scan is a special case of Index Seek,
which means that when we see Index Seek in the execution plan, it does NOT mean that storage engine does NOT scan all rows. Right?
Alexey

Special Characters in search terms and in data

I'm having a hard time making a decision about what types of special characters I should support in my Contains search.
I know that some of my data has dashes in it like '1034-AMFM' but if a user puts that in the search term it will be interpretted as a special character by OracleText correct?
What I have resorted to at the moment is stripping all special characters out of the users search terms but this severely limits the capabilities of Oracle Text and what I'm stuck with is a very basic search tool.
Is there a way to find a happy medium here?

You need to use a backslash, not a forward slash. The following demonstrates the behavior under different circumstances, such as specifying the hyphen as a printjoin or skipjoin or whitespace, which is the default, with and without escaping:

How can I find special characters in a string

Hi,
I have a small task where I have to find special characters in a given string, Can anyone suggest.......................

What is your definition of a "special character", could you be a bit more specific?
Do you simply want to find the position of a specific character in the string?
Can it occur more than once and you want to find all occurences?
What should happen if the special character does not exist?
For programming purposes, all 256 possible 8 bit characters (x00-xFF) can be treated the same. Non-printing characters can be entered in \-codes or hex display if needed.
