Regular Expression in 11g

I am using the following SQL to implement IN condition when the values coming as ,KA,TN,KL,
SELECT * FROM WHERE STATECD IN
(SELECT UPPER(TRIM(SUBSTR(',KA,TN,KL,',
INSTR(',KA,TN,KL,', ',', 1, ROWNUM) + 1,
(INSTR(',KA,TN,KL,', ',', 1, ROWNUM + 1) -
INSTR(',KA,TN,KL,', ',', 1, ROWNUM) - 1))))
FROM all_objects
WHERE ROWNUM < = LENGTH(',KA,TN,KL,') - LENGTH(REPLACE(',KA,TN,KL,', ',')) - 1)
FROM STATE
Want to know how to implement same using regular expression?

This is the forum for issues with the SQL Developer tool. Your post would be better place in the SQL and PL/SQL forum

Help in query using regular expression

HI,
I need a help to get the below output using regular expression query. Please help me.
SELECT REGEXP_SUBSTR ('PWRPKG(P/W+P/L+CC)', '[^+]+', 1, lvl) val, lvl
FROM DUAL,(SELECT LEVEL lvl FROM DUAL
CONNECT BY LEVEL <=(SELECT MAX ( LENGTH ('PWRPKG(P/W+P/L+CC)') - LENGTH (REPLACE ('PWRPKG(P/W+P/L+CC)','+',NULL))+ 1) FROM DUAL));
I need the output as
correct result:
==============
val lvl
P/W 1
P/L 2
CC 3
But i tried the above it is not coming the above result. Please help me where i did a mistake.
Thanks in advance

Frank gave you a solution in your other thread. You could simplify it if you are on 11g:
SQL> select * from table_x
2 /
TXT
TECHPKG(INTELLI CC+FRT SONAR)
PWRPKG(P/W+P/L+CC)
select txt,
 regexp_substr(
 txt,
 '(.*\()*([^+)]+)',
 1,
 column_value,
 null,
 2
 ) element,
 column_value element_number
from table_x,
 table(
 cast(
 multiset(
 select level
 from dual
 connect by level <= regexp_count(txt,'\+') + 1
 as sys.OdciNumberList
order by rowid,
 column_value
TXT ELEMENT ELEMENT_NUMBER
TECHPKG(INTELLI CC+FRT SONAR) INTELLI CC 1
TECHPKG(INTELLI CC+FRT SONAR) FRT SONAR 2
PWRPKG(P/W+P/L+CC) P/W 1
PWRPKG(P/W+P/L+CC) P/L 2
PWRPKG(P/W+P/L+CC) CC 3

Does Oracle Database Express Edition 11g support CLOB datatype?

I am having problems in displaying CLOB data type columns when I query my tables in Oracle Database Express Edition 11g. I am getting garbage values. However when I do the exact same thing in the Enterprise Edition I do not have any problems. So I am thinking that the Express Edition does not support CLOB data types due to its size limitations. Am I missing something here?

Hi, and welcome to the OTN forums!
I download a year ago oracle 10g and installed in windows7/64bit.
Now 11g is available. But it says does not work in x64.Well, in fact, 10.2 XE wasn't certified for x64 either, not even for Linux x64...
11.2 XE has a Linux x86_64 release, and there has been an announcement that there'll be a x64 release for Windows as well, but it's not available (yet).
There have been a lot of reports that people got 11.2 XE work on x64 Windows machines as well, with a few tweaks at installation time and/or afterwards...
You'll find tons of posts on that topic when using forum search...
oracle 10g seems to be not available anymore.Right, the official downloads have been removed after all database 10.2 releases fell out of (regular) support.

Oracle Database Express Edition 11g Database; Tables bigger than 11 GB

Dear all,
is it possible to make a part of big Tables (14 GB) visible in Oracle Database Express Edition 11g Database?
If yes, it would be nice to get the correct development.
Thanks in advance.
Regards
Peter

or maybe there is another software which can import only specified number of rows/bytes? Then you would need to export according to "another software" rules/format as well.
As the table is not that big, one could copy the table, delete selected rows large enough, and export from that table copy instead.
If it's not possible, could you please be so kind and provide the full test-version of Oracle database without 11GB limitation?Oracle provides, under the OTN downloads license, SE and EE editions. See http://www.oracle.com/technetwork/indexes/downloads/index.html

Regular expression to add undesrcore before single capital

I am trying to convert the names of attributes that use capitalization sort of like camelcase to distinguish multiple words, e.g. VehicleColor to use underscores instead, eg. Vehicle_Color.
I have a regular expression that does this, however I have a problem when an abbreviation consisting of multiple upper case characters is present, e.g. AverageMPG becomes Average_M_P_G. I am trying to come up with a pattern that only adds the underscores to the first occurrence of a capital letter in a series which should result in the abbreviation MPG becoming Average_MPG.

Regular Expression Abbreviation of Words

Suppose I have got data in my column like
Balla Ram Chog Mal College
Maharishi Dayanand University
Cambridge Public School
Now I want to write a query using regular expressions to find out the abbreviations. e.g the resulting data set should be:
BRCMC
MDU
CPS
How should I write regexp for it ?

One way, using SUBSTR and INSTR, tested on 10g.
with data as
select 'Balla Ram Chog Mal College' col from dual union all
select 'Maharishi Dayanand University' col from dual union all
select 'Cambridge Public School' col from dual
select col, replace(ltrim(max(sys_connect_by_path(str, ',')) keep (dense_rank last order by r), ','), ',') abbr
from (
select col, substr(col, decode(level, 1, 1, instr(col, ' ', 1, level - 1) + 1), 1) str, level, row_number() over (partition by col order by level) r
from data
connect by level <= length(col) - length(replace(col, ' ')) + 1
 and col = prior col
 and prior sys_guid() is not null
order by col, level
group by col
start with r = 1
connect by r - 1 = prior r
 and col = prior col
 and prior sys_guid() is not null;
COL ABBR
Balla Ram Chog Mal College BRCMC
Cambridge Public School CPS
Maharishi Dayanand University MDU
With 11g, you will not require the Outer query to concatenate the results, you can directly use LISTAGG as demonstrated by Hashim.

Logical AND in Java Regular Expressions

I'm trying to implement logical AND using Java Regular Expressions.
I couldn't figure out how to do it after reading Java docs and textbooks. I can do something like "abc.*def", which means that I'm looking for strings which have "abc", then anything, then "def", but it is not "pure" logical AND - I will not find "def.*abc" this way.
Any ideas, how to do it ?
Baken

First off, looks like you're really talking about an "OR", not an "AND" - you want it to match abc.*def OR def.*abc right? If you tried to match abc.*def AND def.*abc nothing would ever match that, as no string can begin with both "abc" and "def", just like no numeric value can be both 2 and 5.
Anyway, maybe regex isn't the right tool for this job. Can you not simply programmatically match it yourself using String methods? You want it to match if the string "starts with" abc and "ends with" def, or vice-versa. Just write some simple code.

Help in Regular expression

Hello..
I wanted to write a regular expression to match the foll string..
 
 NEW ORLEANS, Louisiana (CNN)

I tried doing..
Matcher matcher= Pattern.compile(" ([^<^>]+?)", Pattern.CASE_INSENSITIVE).matcher(story);
Its not working...
is there any other soln?

Theres probably a better way to do this but here's a way that works.
import java.util.regex.*;
public class RegexTester{

 String text =
 " " +
 " NEW ORLEANS, Louisiana (CNN) " +
 "-- Two years after Hurricane Katrina devastated coastal areas of Louisiana and Mississippi," +
 "residents say much of America has forgotten their plight." +

 String regex = ">((?:\\s*[\\S&&[^<>]]+\\s*)*?)<";
 Pattern p = Pattern.compile(regex);
 Matcher m = p.matcher(text);
 while(m.find()){
 System.out.println("Match: '" + m.group(1) + "'");

but its giving results for all above expressions while i want different expression for each.
i hav used * after [:digit:]{4}, when i am using ? or . then its giving no results. Please help in this situation ASAP.
Thanks

I dont get your question Can you post your desired output? and also give some sample data.
Please consider the following when you post a question.
1. New features keep coming in every oracle version so please provide Your Oracle DB Version to get the best possible answer.
You can use the following query and do a copy past of the output.
select * from v$version 2. This forum has a very good Search Feature. Please use that before posting your question. Because for most of the questions
that are asked the answer is already there.
3. We dont know your DB structure or How your Data is. So you need to let us know. The best way would be to give some sample data like this.
I have the following table called sales
with sales
as
 select 1 sales_id, 1 prod_id, 1001 inv_num, 120 qty from dual
 union all
 select 2 sales_id, 1 prod_id, 1002 inv_num, 25 qty from dual
select *
from sales 4. Rather than telling what you want in words its more easier when you give your expected output.
For example in the above sales table, I want to know the total quantity and number of invoice for each product.
The output should look like this
Prod_id sum_qty count_inv
1 145 2 5. When ever you get an error message post the entire error message. With the Error Number, The message and the Line number.
6. Next thing is a very important thing to remember. Please post only well formatted code. Unformatted code is very hard to read.
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.
<place your code here>\
7. If you are posting a *Performance Related Question*. Please read
 {thread:id=501834} and {thread:id=863295}.
 Following those guide will be very helpful.
8. Please keep in mind that this is a public forum. Here No question is URGENT.
 So use of words like *URGENT* or *ASAP* (As Soon As Possible) are considered to be rude.

Regular expression alphabets

Hi

Hi,
Try this

VTThat won't work as it's expecting at least two characters with the first having to be a-z (lower case) or space or "-" followed by A-Z (upper case) or space or "-".
The correct way is either:
[a-zA-Z -]or
[[:alpha:] -]using the alpha set is often preferable as it can work differently with different character sets/languages rather than restricting to just the a-zA-Z ranges.
Generating a reference for your own database characterset/language can be useful...

Urgent!!! Problem in regular expression for matching braces

Hi,
For the example below, can I write a regular expression to store getting key, value pairs.
example: ((abc def) (ghi jkl) (a ((b c) (d e))) (mno pqr) (a ((abc def))))
in the above example
abc is key & def is value
ghi is key & jkl is value
a is key & ((b c) (d e)) is value

can anybody pls help me in resolving this problem using regular expressions...

Bracket in Regular Expression constant?

I am a bit puzzled by the behavior I am experiencing in LV 2011. I hope to get some light from experts out there.
I am trying to parse a messy ASCII header file and after having split it into individual lines (strings), I use the "Match Regular Expression" function to remove some of the info before the substantial information.
Some of the strings include square brackets ([, ]), which are special characters for the function, therefore, as documented in the help, one needs to precede them with a backslash.
Example:
I want to parse the following line:
#PR [PR_DEV,I,2]
One way (which I am using because of considerations related to the rest of the header) is the the following:
Note that the first string constant is using "Code Display" whereas the second one is using "Normal Display".
Why did I not put a backslash in front of the bracket in the first string, you may ask? Well, I did, but it disappeared after I typed the other characters. And reverting to "Normal Display" did not restore it.
Of course, the first version does not parse the input string correctly, whereas the second one does it fine.
In other words, the custom display string (which is convenient for cryptic codes such as \s* or to distinguish between space and tab...or simply ENTER tabs!) seems to mess up with the \[ combo (likewise with the \] one).
It is not a huge deal. I can use the "Normal Display" mode, but I tend to think that this qualifies as a hidden "feature". And again, it is still a pain in the ... when dealing with special characters such as tabs, etc...
Solved!
Go to Solution.

I think that [ is a special character which needs to be preceded by a backslash, but it is not one of the defined backslash characters (like \s). So, you need to put in two \\ to get one \ while in '\' Codes Display.
You can put in any character by using \xx where the xx is a hex character using only upper case letters for A..F. I converted the strings to byte arrays and tried to see what made the arrays match and the Match work.

How to solve this ?
Thanks in advance.

Shouldn't that be Acinetobacter?
edit: nope, I'm wrong, you're right.
