How To Find Terms In A File Name: Regular Expression OR A String Function
Oct 15, 2007
hi,
i am using a forEach look to import each file within a folder, but i also need to calculate the dataset related ot these files.
the file are named as:
ff_inbound_20071008_1.csv
ff_inbound_20071008_2.csv
where for file ff_inbound_20071008_1.csv:
ff => flat file
inbound => dataset of this csv
20071008 => date
1=> file count
having in mind that they are store in the variable as a full path:
z:myFlatFilesexportsproj01ff_inbound_20071008_2.csv
i need to extract the dataset and the date for each file.
how can i extract these terms from the file name?
many thanks,
nicolas

I am writing an SQL query to find an replace data in a column. I have a table that is filled with
C:usersXXXXappdata
C:usersYYYYappda
C:usersZZZZZZappdata
I would like to replace the c:usersXXXXX part with %userprofile%
The end result would be %userprofile%appdata
I know how to dot the replacement in powershell. it's quite easy
-replace "c:users[^]+","%userprofile%"Â Â
Basically how would transfer this into SQL...

Thanks in advanace for taking the time to read this post.
I am using MSSQL 2005 and have created a function that allows me to use regular expressions in my SQL queries.
My question is I have a pattern buried in a field of misc data that I need to pull out just that pattern and discard the rest of the data. Here is the Regular Expression I am using
select field1 from table1
where dbo.RegExMatch (field1,'[a-zA-Z]{4}[0-9]{6}[a-zA-Z]{2,4}')=1
This returns all values in the field that match the expression. What I want to do now is remove all data from the field on the left and right of the expression that does not match the expression. How would I accomplish this without reading through the 200k+ records and writing rules for every exception I run across?
so I could have Gar b/a ge 'THE GOOD DATA' m/or1 ba4d da....ta. All I want to do is return 'THE GOOD DATA'

HiI'm looking to return rows from a table where a column is LIKE a keyword. This is my current code:SELECT DISTINCT business_name FROM Table WHERE business_name LIKE @keyword + '%' ORDER BY business_name ASCThe problem with this is that if a business is called "The White Ship Inn", and the keyword to match is "White Ship" it will not match. If i put another wild card in front of @keyword then this finds too many matches - i need it to match against columns which either start with the keyword, or have a whitespace in front of them. Is there some kind of T-Sql i can use or will i have to go down the regex route (using this (http://www.codeproject.com/KB/mcpp/xpregex.aspx)) ?cheers

Does SqlServer support Regular expression?
I want to know if it's avilable or not...
And if it's not available, I want to know any other efficient way to validate string.. manipulating Regular expression style validation.
Thank you all...

I need to remove all the [ and ] in every sql stmt where they are usedto close encircling numeric value, fyi, all these sql stmt areconverted from an Access db. For instance,select *from XYZtblwhere fieldA = [1] or fieldA = [2] or fieldA = [3]to beselect *from XYZtblwhere fieldA = 1 or fieldA = 2 or fieldA = 3-- and of course I'd have written in as follows, but that's not-- the pointselect *from XYZtblwhere fieldA IN (1,2,3)Thanks.

I am try to build a query which only matches whole words and so far I've got this.
Code:
SELECT *
FROM tblSearchWords
WHERE CorrectSpelling LIKE '%[^a-zA-Z0-9]blah[^a-zA-Z0-9]%'
This will return rows which contain the string 'blah' without any numeric or alphanumeric characters beside it. However it doesn't return the rows where 'blah' is either at the start or end of the string as it expects any character except a-zA-Z0-0.
Is there any way to accept string when there is nothing on either side as well?
Thanks,
Goran

I am trying to exclude all strings that has 'a' inside (I havesimplified the actual problem)select 1where 'bb b a dfg' like '%[^a]%'However, the above does not work. By the way, I can not use 'not like'such as:select 1where 'bb b a dfg' not like '%a%'Although the above will work but the idea is that I have to use 'like'and not 'not like'. This is partly because I have to exclude rows froman exclusion table (a table that has many rows that will be excluded).Actually I want to include all srings that has lets say // in it usinga regular expression. I would like to write it as (I am sure it willnot work):select 1where column like '%[^/][^/]%'That should exclude strings like: 'aaa // aa aa' or 'bb bbb // bb' etcand include strings like: 'aaa aa aa' or 'bb aa nn' etcIs there any way to write a regular expression to do it? Otherrwise Ihave to solve this problem without using regular expressions in theexclusion table.Thanks.

Hi
I have a table which stores a big chunk of html text, which I have to search for and replace some strings.
How can I write a query that makes use of regular expressions to do the following:
Below is a block of example text
======================================================================
" src="http://aaaa/bbbb/cccc.nsf/blind%2010x10.gif?OpenImageResource" width=10> <img height=10 alt="" src="http://aaaa/bbbb/cccc.nsf/blind%2010x10.gif?OpenImageResource" width=10><img height=11 alt=""
http://aaaa/bbbb/cccc.nsf/blablablabla?OpenDocument src="http://aaaa/bbbb/cccc.ns http://aaaa/bbbb/cccc.nsf/d8d4f0dfa09ba71142256cc50040ee51/ee9b4493dac727be422571c30027df61? OpenDocument" target=_self>
======================================================================
Now I want to search and replace the string that is highlighted in red with something like "FOUND"
The below string is what I want to search for - I will used PATINDEX on the string below to find the start index of the string in the body, and then I will add on 114 to the when doing a replace:
'%http://aaaa/bbbb/cccc.nsf/%some guid%/%some guid%?OpenDocument%'
For example
REPLACE
(
TheField,
SUBSTRING
(
TheField,
PATINDEX(''%http://aaaa/bbbb/cccc.nsf/%some guid%/%some guid%?OpenDocument%', TheField),
,114
)
,
'FOUND'
)
QUESTION:
what would the regular expression be and how does one type it in the query?
I tried something like the below but it does not work, please advise .....
[a-z][0-9]{32} %/% [a-z][0-9]{32}

I have as csv-file wich I import into an SQL Server table. Now I want to do some checks on it. I use a conditional split to direct data to the other tables (1 table for the correct data, 1 table for the rejected data).
Is it possible to use a regular expression in a case in a conditional split to check if a columns has the right format?
If yes? How do I do that?
If no? What is the alternative?
Thanks!

The problem that I am having is that with Visual Web Developer I am creating a webpage and having it directly put online, so for example when I start a new ASP.NET page, I select the location to be HTTP, with the location http://MYWEBSERVER/Website and for the language and Visual BasicI notice a couple of things, first that there is no longer a a link under the Main toolbar "Website" selection called the ASP.NET configuration. So how can I configure what I want to have users be able to do? It seems that this choice is only available if I am building the ASP.NET page on my "localhost". So that is the first problem. So I am able to get the pages to work, atleast the things such as the textboxes to show up etc, (Even things as advanced as the "Login" box). How ever when I try to get someone to try to login I am taken to a page that has an server error. The error is:
"The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file. "
The Stack Trace Errors are at the bottom. I think this is happening because the automatically generated databases are not getting built online as they are on my computer. On my computer I have MSSQL express. So either the databases are not getting built for some reason, (and I think that is the case as I don't see any in the folder). So I think that somehow I have to create a database on my server, and then somehow configure the ASP.NET file, perhaps in the Web.Config file to look for that new database. Is this the correct methodology? Is there some simpler way that I can just somehow upload things as they are and have them work correctly on my server? The error says that either the Server did not find the database or that the trust level was insufficient. I don't think that is it as I just looked again and I don't see any .MDF files. So how would I go about getting this to work right? Is there a way to do this with MySQL also? So that I don't have to use MSSQL? My server only allows 1 DataBase for that.
Thanks and I hope my question makes sense. It is basically how can I get it to be able to create and check users etc. online?

I'm having problems designing a package to attempt to execute a fast load data transfer but failback to regular speed with error redirection in the event of an error.
The way I designed this was to add one data flow task to my package called "DFT FASTLOAD". The data flow copies a table SRC to another table DEST in the same SQL Server database. In the error handler for the data flow task I copied the original data flow task and changed the name to "DFT REGULARLOAD with Error redirection". In this data flow task I did not use fast load and addtionally redirected errors to a text file.
In the Data Flow Task "DFT FASTLOAD". I am copying from a varchar source field(with non-date strings) to a datetime destination field to force errors. However the Data Flow Task "DFT REGULARLOAD with Error redirection" never seems to start transferring data from source to destination. The data Flow Task "DFT REGULARLOAD with Error redirection" turns yellow (after the error occurs in "DFT FASTLOAD"), but no data is being transferred). It seems like it hangs.
Do I need to increase the MaximumError Count or something? The data flow task "DFT FASTLOAD" does not turn red when the error occurs it just remains yellow, so i assume I'm on the right track since it seems the error is caught.
I have added screenshots ... hopefully these screenshots will clarify my problem.

I have created a function to return values, which works fine, but I can't do calculations in it.
CREATE FUNCTION [dbo].[tf_Asset_Portfolio](@deal_id int,
@as_of_date datetime)
RETURNS TABLE
AS
RETURN ( SELECT DISTINCT dbo.Assets.issue_id, SUM(DISTINCT dbo.Assets.par_amount) AS par_amount, SUM(DISTINCT dbo.Assets.par_amount) AS market_value
FROM dbo.Issue INNER JOIN
dbo.Assets ON dbo.Issue.issue_id = dbo.Assets.issue_id INNER JOIN
dbo.Issuer_Rating_History ON dbo.Issue.issuer_id = dbo.Issuer_Rating_History.issuer_id
WHERE (dbo.Issuer_Rating_History.as_of_date <= @as_of_date)
GROUP BY ALL dbo.Assets.issue_id, dbo.Assets.deal_id, dbo.Issue.default_date
HAVING (dbo.Assets.deal_id = @deal_id) )
I need to do calculations on market value based on the default date.
If default date isn't specified then it should be 100% of par amount.
If default date is less than one year ago - 65% of the par_amount.
If default date is one or more years ago - 0.
I have no idea about how to do this and everything I try wont work.
I created another function to do the calculations and this seems to work, but it only does one record instead of all of them.
CREATE FUNCTION dbo.tf_Asset_Portfolio2
(@deal_id int,
@as_of_date datetime)
RETURNS @Market TABLE
(issue_id int, par_amount money, market_value money)
AS
BEGIN
DECLARE @ReturnDate datetime
DECLARE @DD datetime
DECLARE @PA money
DECLARE @MV money
DECLARE @ID int
DECLARE @DateD int
SELECT TOP 1
@ReturnDate = LAST_BATCH
FROM master..sysprocesses
WHERE SPId = @@SPID
SELECT @ID = issue_id FROM Assets WHERE Assets.deal_id = @deal_id
SELECT @PA = SUM(DISTINCT par_amount) FROM Assets WHERE Assets.issue_id = @ID AND Assets.deal_id = @deal_id
SELECT @DD = default_date FROM Issue WHERE Issue.issue_id = @ID
SET @DateD = DateDiff("yyyy", @DD, @ReturnDate)
If @DD = Null
BEGIN
SET @MV = @PA
END
Else If @DD > @ReturnDate
BEGIN
SET @MV = @PA
END
Else If @DateD < 1
BEGIN
SET @MV = @PA * .65
END
Else If @DateD >= 1
BEGIN
SET @MV = 0
END
insert into @Market
(issue_id, par_amount, market_value)
values
(@ID,@PA,@MV)
RETURN
END
I need to combine the functionality of being able to return mutliple records that isn't in the 2nd function and being able to calculate the market value which isn't in the first one. Please help. Thank you in advance.

Hi, I am a new to Reporting Services...
I am using RS2000
I am trying to apply cint function in the expression editor for the textbox
eg. i type in =cint(Fields!firstfield.Value/Fields!secondfield.Value).
This is returning error
The value expression for the textbox €˜HoldDuration€™ contains an error: Arithmetic operation resulted in an overflow.
Could you please let me know what I did wrong in this and how to correctly apply VB or any custom functions in the expression editor where the expession output would be a decimal value and you are interested in getting an integer value by rounding the fractional part.

2 278*(1/4)-2
3 81*(3/5) +4
I now have the expression as an nvarchar. (Ex: 8*(1/2)-6)
Now I need to evaluate this expression and output the result (which is -2 in above Ex) .Can someone give me idea on how do I evaluate the expression which is available as a string. I need to write a procedure for this.
I am unable to cast/convert nvarchar to float/int
Any sample code would be greatly appreciated.
This a very urgent requirement for me.Please get back
Thanks
Swapna
