How To Find Terms In A File Name: Regular Expression OR A String Function
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

Using A Regular Expression In MSSQL 2005 To Find Patterns Buried In A Field Full Of Misc Data
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'

How To Convert A Returning String From Custom Code To A Function In Expression?
I have a custom code function that return string like: "SUM(Fields(Parameters!dept.Value + ""_1HeadCount"").Value) + SUM(Fields(Parameters!dept.Value + ""_2HeadCount"").Value) + SUM(Fields(Parameters!dept.Value + ""_3HeadCount"").Value) " How do I convert this string to a function inside the expression (in this case "SUM", "Fields", "Parameters!", etc.)? The expression of my TextBox show the string as a string instead of converting them to proper function and display the corrent value. The reason I need to build the string is because the Fields number is dynamic and I need a loop to increase the number in the field name. Any suggest is highly appreciated! Thanks, Tabbey

Regular Expression?
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.

Regular Expression?
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

Regular Expression Issue
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.

Regular Expression For Whole Words
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

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 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?

Capitalize A Text String/String Function Related
Hi Folks: How can I capitalize a string like 'JOHN DOE' into 'John Doe' with one SQL statement. SQL does provide string function like LOWER(char_expr) which would change the whole text string to 'john doe' and I don't want that. So far, in order to do that, I have to use a front-end development language like 'Omnis' which has a string function 'cap()' to capitalize the whole string, then update the back-end SQL with the new string.

Attempt FASTLOAD If Error Perform Regular Data Flow Transfer And Redirect Errors To Text File
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.

String Formatting Expression Problem
I have what should be a simple string formatting issue -- removing all alpha characters from a phone number. T-SQL below is simple and works just fine: declare @home_phone as char(14); set @home_phone = '(123)979-3206'; set @home_phone = REPLACE(@home_phone,'-',''); set @home_phone = REPLACE(@home_phone,'(',''); set @home_phone = REPLACE(@home_phone,')',''); The condensed version below works equally well: set @home_phone = REPLACE((REPLACE((REPLACE(@home_phone,'(','')),')','')),'-',''); Either script above returns correct result: select @home_phone; Result = '1239793206' HOWEVER, within SSIS Derived Column expressions, this function fails to remove parentheses. First of all, Expression Builder doesn't like outer single quotes (turns red) which I resolved by using double quotes resulting in the following expression: REPLACE(home_phone,"-","") + REPLACE(home_phone,"'('","") + REPLACE(home_phone,"')'","") Unfortunately, this expression fails to remove parentheses and instead returns: '(123)9793206' I've tried several different permutations--no inner single quotes; adding more inner single quotes; etc., but so far no success. Any suggestions would be much appreciated!

String Parsing And Expression Builder....
I can't figure this one out. I don't have enough knowledge of the string functions I guess. I need to pull a value out of a variable I setup in a for each loop. The value is the filename/path of each source file being processed. Let's say the variable that has the source file path is called VAR1. One sort of off topic thing I've noticed is when watch the variable in bebug mode and I look at the value of VAR1 it has double back slashes. Here's an example of the value of VAR1: "\\L3KRZR6.na.xerox.net\C$\Documents and Settings\ca051731\Desktop\Project4\DPT_20070926.ver" How come the back slashes have been doubled? And do I need to account for that when I start parsing the string value? Anyway, I need to grab part of the filename from VAR1 and I need the value populated at the start of the for each loop container - ideally when I capture VAR1 in the for each container. I'll be using the string in drop table, create table and create index statements before the actual Data Flow task within the overall package In the above example I need to grab the characters before the underscore and after the last \. So I'd need the string "DPT" captured in this example. The actual string could be 1 to 3 characters long, even though this example has it as 3 long. Underscores could exist anywhere in the actual UNC path once this package is moved to our actual system environments so I can't key off of the underscore. Because I can't count on the string being a fixed lenght I can't just use a positional string function and grab specific text starting/ending at specific points. Is there a way to use the various string functions in the expression builder to grab the text between the right most underscore and the right most back slashes or something like that? Ideally I'd like to setup a new expression based packed scope variable called VAR2 and build it using string functions applied to VAR1.

I am using an expression for a data source connection so I can decide which server/database to use at runtime. I also need to pass credentials to use for that connection. The only way I'm able to get this to work is to specify "No Credentials" for the data source and then pass a DataSourceCredentials to the report throught the report viewer. This works, for the most part, but puts a "Change Credentials" link in the report viewer. What I think would be much better is if I could specify the credentials in the connection string that I pass. However, everything I've tried so far has not worked. I get errors complaining that the compination of options is invalid or that the report server cannot find the credentials of "unknown keyword: User Name". All by trying various combinations of things. How do other people go about this? I've seen blogs implying that this is not such a big deal (that credentials CAN be passed over in the connection string). Hopefully I'm missing something simple here. If I have no choice, the "Change Credentials" link will not be the end of the world, but that's very sloppy. The people viewing this report will not know anything about the database credentials and I'd rather not show them somthing as inviting as a link that can get them off track. Thanks for your help! -C

Converting A String Expression To Proper Case
How would I convert an expression like on of these to all upper case first letters with remaining letters lower case? VB has a function for that but sql doesn't seem to. I thought about having a loop go through each character to check for spaces. I've written a couple of similar pieces of code in VB when a while ago, but is there a better way? Thanks :) Just a couple of typical examples of how the data should appear ~ payment, credit card ==> Payment, Credit Card butcher & singer ==> Butcher & Singer

Filters && Expression With String Values, Should They Work??
Any idea why this expression would not work in SSRS? Based on a expression on a group textbox I get 0 records that match: =Iif(Fields!ACCRUAL_CODE.Value <> "A", CountDistinct(Fields!LOAN_NBR.Value), 0) I've evaluated in the proc & there should be a count of 29 records. I found a work around by using this in the stored proc & I get my record count: ACCRUAL_CODE = CASE WHEN BASE.ACCRUAL_CODE = 'A' THEN 0 ELSE 1 END and changed the expression in SSRS to this & it works: =sum(Fields!ACCRUAL_CODE.Value) Is this a known issue with strings? From searching on this site I see that string evaluations are widely used so I do not see why it wouldn't work. I've also see this when filtering the dataset on anything that is a character. Any suggestions?

Problem With Expression Based Connection String
We're using RS2005 and have a report that we want to be able to dynamically select what database server we use at runtime. For this report we are using private OLE DB datasources to connect to Sybase ASA 9 databases. I have created a parameter for the database server name and modified the datasource connection string ="Provider=ASAProv.90;Data Source=" & Parameters!db.Value This works fine in the IDE but when we publish to the server we get the following error: An error has occurred during report processing. Cannot create a connection to data source 'rpASA_02'. Database server not found I can create expression based connection strings against MSSQL and everything works fine on both the IDE and RS server. Why doesn't this work with OLEDB? Am I doing something wrong or is this an MS bug? tia -bruce

SUM Of Report Field With Expression Which Has COUNT Aggregate Function
Hi everyone, I have created a report which has 3 groups. The report output as shown below. I am having trouble getting the SUM of Total Credtis for each Org. Can't seem to get the total 42 and 16 (highlighted), but can get total unists 11 and 13. I get expression contains aggregate function. This is because Units assessed is the Count of IDs (details hidden from the report). Report has three groups Org , Assessor and Unit. Can someone please help me with this? Appreciate help. Thank you, Ski Org 1(Group1) Unit Credits Units Assessed(# of Trainees) TotalCredits Assessor 1 Unit 1 2 4 (Count of Ids) 8 (2*4) Assessor 2 Unit 2 1 2 2 (1*2) Assessor 3 Unit 3 5 2 10 (5*2) Unit 4 2 1 2 Assessor 4 Unit 5 10 2 20 -------------------------------------------------------------------------------------------------------- 11 42 ----------------------------------------------------------------------------------------------------------- Org 2 Assessor 3 Unit 1 2 3 6 Assessor 4 Unit 6 1 10 10 -------------------------------------------------------------------------------------------------------- 13 16 --------------------------------------------------------------------------------------------------------

Expression Based Connection String && Stored Procedures
I have been looking around on this forum and on other sources on the web about expression based connection strings in rs2005. From my own trials and from what others have reported it seems that you can not use expression based connection strings with stored procedures. Can anyone confirm that rs2005 does not have the ability to do this? Or alternatively has anybody been able to successfully use an expression based connection string with a stored procedure?

Frror: 4000 Max String Literal In Expression For Datareader Component
Hi, I have a datareader component of which i am dynamically setting its sqlcommand statement with expression (click the background of dataflow > properties > expressions). Now my sql select statement has about 600 fields so that makes my expression statment "select field1, field2, .....from table1 where field2 >=" + @[User::dateforfield2] but when i evalute the expresssion (which is right), i get the error: A string literal in the expression exceeds the maximum allowed length of 4000 character and i think its because of the fields in my select statment causing my string literal to grow more than 4000 characters. Is there any way to increase the max string literal for expressions. Please help.

Can I Apply A Database Function Or Assembly Call In An Expression For Filter Data?
I need to translate a user€™s regional setting into one of our own language codes before I send it through as a filter to the model query. If our language codes were the same, the filter would look like this in the report filter - Language Code = GetUserCulture() Which translates to this in the database query (for us english) - table.language_code = 'EN-us' And of course I need it to look like this - table.language_code = 'ENG' I would like the logic to be globally available to all report writers (ie not forcing each report writer to have an iif or case stataement). I was thinking custom assemblies or maybe a database function, but at this level of the filter, I cannot seem to figure out how to embed a database function call to apply to the filter criteria like this Language Code = dbo.ConvertFcnIWrote(GetUserCulture()) Or how I would access the custom assembly in the filter expression. Do you have a recommended implementation for this situation? Thanks, Toni Fielder

Sql String Find With &&
I have a visual studio 2005 app that has to match strings to something in a database. It works wonderfully until a string shows up with an & in it (so "this & that") The app wont find anything even though it should, the same query that is made in VS works just fine in enterprise manager I tried a replace on the & with the chr(), hex, and html reference for & and none of those work. We tried using different methods in VS to do the sql statement and commands. The statement surrounds the string with single quotes. If we take the & out, everything works fine. Turned off request valadation just in case. Any ideas?????
