Regular expression for recognizing all tables in a sql statement
Hi all
I need a regular expression for recognizing all the tables bane in a geberic statement.
Unlikely i need a regular expression that manage also inner join .I 'm sorry but this matter is new for me and i cannot find any usefull help in the web.
Regards
If you insist it should be something like:
"SELECT ([A-Z0-9_]+)[.][A-Z0-9_]+(,([A-Z0-9_]+)[.][A-Z0-9_]+)* FROM (([A-Z0-9_]+)[.][A-Z0-9_]+) INNER JOIN (([A-Z0-9_]+)[.][A-Z0-9_]+) ON .+" plus spaces etc... Yes it's for this kind of statements only.
But SQL parser is better because anyway you'll need to at least remove duplicates from founded names...

Issues regular expression for "find all" feature
Hi,
I am currently working on a website in dreamweaver that
contains about 2000 pages. I know some of these pages are missing a
div called id="breadcrumb". I have tried to find a way to search in
the "entire current local website" for pages that do not contain
any div with the id="breadcrumb". However, it does not seem to
work, I tried using the {n} syntax as {0} but it doesn't return
anything I expect, which is pages that do not contain
id="breadcrumb".
Thanks for your help.

An option:
Is this div normally next to another unique HTML element on
the page that is
in all pages? Like this:
<div id="xyz">
<div id="breadcrumb">
If so, you could to a find for:
<div id="xyz">
and replace with:
<div id="xyz">
<div id="breadcrumb">
Then, since the pages that already had the breadcrumb div
would now have
both, you do a second search and replace to remove the
duplicates:
find:
<div id="breadcrumb">
<div id="breadcrumb">
replace:
<div id="breadcrumb">
Of course, you'd still have to worry about the closing
</div> tag and that
might get tricky.
Ultimately, though, a site with 2000 pages really is a likely
candidate for
a migration into a CMS instead of manually having to maintain
individual
HTML files like this.

Request some help, over procedure's performance uses regular expressions for its functinality
Hi All,
Below is the procedure, having functionalities of populating two tables. For first table, its a simple insertion process but for second table, we need to break the soruce record as per business requirement and then insert into the table. [Have used regular expressions for that]
Procedure works fine but it takes around 23 mins for processing 1mm of rows.
Since this procedure would be used, parallely by different ETL processes, so append hint is not recommended.
Is there any ways to improve its performance, or any suggestion if my approach is not optimized? Thanks for all help in advance.

Many Thanks,
ArpitRegex's are known to be CPU intensive specially when dealing with large number of rows.
If you have to reduce the processing time, you need to tune the Select statements.
One suggested change could be to change the following query
SELECT
REGEXP_SUBSTR(P_EXCEPTION_RECORD, '([^^])+', 1,t2.COLUMN_VALUE) str
FROM
DUAL t1 CROSS JOIN
TABLE
CAST
MULTISET
SELECT LEVEL
FROM DUAL
CONNECT BY LEVEL <= REGEXP_COUNT(P_EXCEPTION_RECORD, '([^^])+')
AS SYS.odciNumberList
) t2
to
SELECT REGEXP_SUBSTR(P_EXCEPTION_RECORD, '([^^])+', 1,level) str
FROM DUAL
CONNECT BY LEVEL <= REGEXP_COUNT(P_EXCEPTION_RECORD, '([^^])+')
Before looking for any performance benefit, you need to ensure that this does not change your output.
How many substrings are you expecting in the P_EXCEPTION_RECORD? If less than 5, it will be better to opt for SUBSTR and INSTR combination as it might work well with the number of records you are working with. Only trouble is, you will have to write different SUBSTR and INSTR statements for each column to be fetched.
How are you calling this procedure? Is it not possible to work with Collections? Delimited strings are not a very good option as it requires splitting of the data every time you need to refer to. -
Hi All,
What should be the regular expression for string MT940_UB_*.txt and MT940_MB_*.txt to be used as filename inSFTP sender channel in PI 7.31 ??
If any one has any idea on this please let me know.
Thanks
NehaHi All,
None of the file names suggested is working.
I have tried using - MT940_MB_*\.txt , MT940_MB_*.*txt , MT940*.txt
None of them is able to pick this filename - MT940_MB_20142204060823_1.txt
Currently I am using generic regular expression which picks all .txt files. - ([^\s]+(\.(txt))$)
Let me know ur suggestion on this.
Thanks

Regular Expression For Dreamweaver
I still haven't had the time to really become a professional when it comes to regular expressions, and sadly I am in need of one an finding it difficult to wrap my head around.
In a text file I have hundreds of instances like the following:
{Click here to visit my website}{http://www.adobe.com/}
I need a regular expression for Dreamweaver that I can run within the "Find and Replace" window to switch the order of the above elements to:
{http://www.adobe.com/}{Click here to visit my website}
Can anyone provide some guidance? I'm coming up short due to my lack of experience with regular expressions.
Thank you in advance!So you have a string that starts { and goes until the first }. Then you have another string exactly the same. And you want to swap them. I'm not making any assumption that the second one has to look like a URL (that's a whole other minefield, but perhaps you could do something simple like it must start with http).
You don't specify how your text file is divided up, have you got this as a complete line to itself, or is it just a huge block of text? Preferably as individual lines.
I don't have Dreamweaver, but this worked for me in Notepad++
Find: ^{(.*?)}{(.*?)}$
Replace with: {\2}{\1}
My file looked like this:
{Click here to visit my website}{http://www.adobe.com/}
{some other site}{http://www.example.com/foo}
And doing a Replace All ended up like this:
{http://www.adobe.com/}{Click here to visit my website}
{http://www.example.com/foo}{some other site} -
Regular expression for LOV?
I have a list of strings in an LOV. I tried filtering it by typing in "^disk" in the search bar, which I hope will return a list of strings starting with "disk", but I failed.
Any idea on how to use regular expression for LOVs? Thanks!HI Buffalo,
i have a select list item in my page1 named :P1_EMPNAME with lov query value
select ename as d, ename as r from emp WHERE EGEXP_LIKE(ename,:P1_SEARCH) or :P1_SEARCH IS NULL
i have a Search text box in my page1 name :P1_SEARCH
When i run the page, by default all the empnames will display in the lov list item
i have given ^buffalo in the text seach item and clicked the submit button ,it shows the Employee buffalo in my list item lov.
If you want all the entries that start with S, search for ^s
End with R, use r$
please try this link http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28424/adfns_regexp.htm

Hi Everyone,
I need help with regular expression for following scenario .
If any of the DBCC command is run against sql server i want it to be captured . Something like if it starts with DBCC it should be captured .
For instance following is expression for
DBCC CheckDB : part="dbcc checkdb", rgxp="(\s|;|^)dbcc\scheckdb\s?\((((to[a-z0-9_\$\#\.\@])|(t[abcdefghijklmnpqrstuvwxyz0-9_\$\#\.\@])|([abcdefghijklmnopqrsuvwxyz]))[a-z0-9_\$\#\.\@]*)\s?\)(\s|;|$)"
But instead of writing expression for all DBCC commands is there any way to write a regular expression say if DBCC i want it to be captured .
Thanks
Suhas VallalaHi Suhas,
As Olaf said, regular expressions is not supported in SQL Server. To trace the DBCC event, you can use the SQL Sever Profiler, just tick the Security Audit--> Audit DBCC Event. You can set up a trace in the profiler by following the below tutorial.
SQL SERVER – Introduction to SQL Server 2008 Profiler
If you have any question, feel free to let me know.

Regular Expression for a Person's Name

How to write the regular expression for Square brackets?
Hi,
I want regular expression for the [] Square brackets.
I have tried to insert in the below code but the expression not validate the [] square brackets.
If anyone knows please help me how to write the regular expression for [] Square brackets.
private static final Pattern DESC_PATTERN = Pattern.compile("({1}[a-zA-Z])" +"([a-zA-Z0-9\\s.,_():}{/&#-]+)$");Thanks
RaghavSince square brackets are meta characters in regex they need to be escaped when they need to be used as regular characters so prefix them with \\ (the escape character).

What is the regular expression for the end of a story?
Forgive me if this is wrong forum for asking this, but I'm trying to use the Find command using GREP and I need to know the regular expression for the end of a story. (Or, the last character of a story.) Thanks in advance.
I'd try search for .\z (that's a dot in front) which ought to find the very last character in the story, and replace with $0 and your additional text.
You know you can use a keyboard shortcut to move your cursor to the end of any story, right? Ctrl + End on Windows, Cmd + End, I think, on Mac. Unless you want to do this to every single story in the document, I would think you might be just as well off to put your text on the clipboard, put the cursor in the story and hit the key combo followed by Ctrl/Cmd + V to paste.
