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.
Having trouble casting GETDATE() to a string value (DT_STR) using expression builder? I want to concatenate the current date to some text used in a send mail task.
I'm new to SSRS (We are using SQL 2014) and have been asked to create a report from SharePoint list data. One of the columns in my list contains XML data. I need to pull three different fields from this XML. I see lots on using xml as a datasource but I'm using a SharePoint list as my datasource. Before I get too far down the wrong road I thought I'd ask here if there was a built in means of parsing XML or if I should look at using the Text Function under Common Functions in the Epression builder?
Hi All, I want to build following code into expression builder . I don't know how to write that things into expression builder. so can you help me out from this problems.
am trying to do the following in SSIS. I have Execute Process Task, in which I have the values are set for Executable, Arguments and working Directory manually. I keep changing this if the Connection Manager points to Dev or when it points to QA or to Prod. Instead I want to do like this. If my Connection Manager points to Dev, the Executale , Arguments and Working Directory should automatically change. Else if it points to QA, the Executale , Arguments and Working Directory should automatically change and similarly for Prod. Is this possible in Expression Builder in Execute Process Task. If so, how?. Thank you
I ran in to a strange problem in Report Builder. I drop a few fields from my Report Model on a simple talbe report. Some of them are straight forwards attributes and some of them are expressions.
Now in the table layout of a report I have say a attribute named as "Account Number". This attribute is actually a field from a table. I change the column header to a two line column header with €œAccount€? on one line and €œNumber€? on second line. No problem, piece of cake.
Now tried the same thing on an expression type attribute, say "Principal Balance". When I split the column header on two line I get this following error.
Semantic query compilation failed: e MeasureNotFound One of the SubtotalMeasures.MeasureName properties of the SemanticQuery refers to the Measure Expression 'Principal Balance', which does not exist. (SemanticQuery ''). ---------------------------- An error has occurred during report processing.
If you read the error you will realize that the query is trying to find an expression named "Principal" (newline char) "Balance" and it fails.
This expression is nothing but a sum aggregation on a field in the underlying table. If I put the "Principal Balance" back on one line report runs like a charm. Also note that exact same report in Designer no issues at all.
FYI: I am in SQL Server 2005 with SP2. (tried it both on Standard and Enterprise versions.)
Nobody answered my previous question. So, I am putting it this way. How to write an IF condition in Expression builder. I want to do something like this. IF (variable1='ABC' then
value = '.......' else variable1 ='DEF' then value = '.......' else variable1='GHI' then value = '.......'
You can perfectly click above "Evaluated value" and see the resutl but I mean, individually over each variable on the variables listview is not possible.
Hello, I am attempting to create an expression for a package variable in a SQL Server Integration Services project, but the elipse button in the expression property for the variable does not appear (Visual Studio 2005). I've tried two different screen resolutions, no luck.
Why would the elipse not be there? Is there a keystroke I can use to open the exrpression builder?
How to remove same repeated string in a column per row from a table? Looked at replace, stuff string functions, but none take a column name as a parameter.
can anybody translate to Transact SQL specifically the example of create function elemIdx i didnt understand how he used recursion may b cuz the language is odd to me i didnt get it
I would like to add additional string functions and other types of functions to the expression builder in SQL Server Integration Services. Right now the list of functions is relatively limited to such things as FINDSTRING, RIGHT, LEN, etc.
<p> Hi everybody, I was hoping to get some advice something I can't quite get my head around. I have a SQL db which contains a table with ratings using the AJAX rating control. When someone rates an object, I need to select the current rating and then use those numbers to; - calculate the new average - add new score to total score - increment number of votes by one.
I thought this can be best achieved using the SELECT statement and then parsing the SELECT string. (is the string comma separated?) using each array, i'd need to convert this into integers and then do the calculation. and re-upload the data to the ratings table (using the UPDATE statement).
Is this the best way of proceeding? I have tried initially to write the code using three sql statements. But that would mean to many requests from the server, right? Below is the conde I have writting already.int myrating; myrating = Rating1.CurrentRating;string getscore = "SELECT " + "RatingScore" +"FROM Rating " + "WHERE ItemID= '" + _ItemID+ "'";string getcount = "SELECT " + "RatingCount" +"FROM Rating " + "WHERE ItemID = '" + _ItemID + "'";string getaverage = "SELECT " + "RatingAverage " +"FROM Rating " +"WHERE ItemID = '" + _ItemID + "'";
int _ratingscore;int _newscore; _ratingscore = int.Parse(getscore); _newscore = _ratingscore + myrating; //add new rating score to old scoreint _ratingcount; int _newcount;_ratingcount = int.Parse(getcount); _newcount = _ratingcount + 1; //increase count by 1int _ratingaverage; int _newaverage;_ratingaverage = int.Parse(getaverage); _newaverage = _newscore / _newcount; //calculate new average rating otherwise otherwise would i be best off to do the following?... string[] dbRatings = SQLstring.Split(','); ?? Any help would be appreciated. Many thanks in advance. Phil
I'm running into a couple of performance issues with regards to the parsing of a text string. We have a function that will take a comma delimited character string, parse out the individual values, and then populate a temp table with those values. The two issues are 1.) the parsing process is VERY slow and 2.) there's a max to how large the string can be - at some point it could easily be 8000 characters or more in length.
Here are the function and the stored procedure wher eit occurs:
CREATE FUNCTION [dbo].[Split](@String varchar(MAX), @Delimiter char(1))
RETURNS @Results TABLE (Item nvarchar(4000))
AS
BEGIN
DECLARE @INDEX INT
DECLARE @SLICE nvarchar(4000)
-- HAVE TO SET TO 1 SO IT DOESNT EQUAL Z
-- ERO FIRST TIME IN LOOP
SELECT @INDEX = 1
WHILE @INDEX !=0
BEGIN
-- GET THE INDEX OF THE FIRST OCCURENCE OF THE SPLIT CHARACTER
SELECT @INDEX = CHARINDEX(@Delimiter,@STRING)
-- NOW PUSH EVERYTHING TO THE LEFT OF IT INTO THE SLICE VARIABLE
it was simple to parse simple variables using replace functions. eg. REPLACE(@str, '@customer_name', @customer_name). It worked like mail merge.the converted string was then sent forward using a webservice.now my requirement is to add conditional values in body field e.g:
body = Document ID: @document_id Customer Name: @customer_name Item name: @item_name Quantity: @qty IF isnull(@rate, 0) > 0 Rate: @rate IF isnull(@rate, 0) > 0 Amount: @amount
how can i parse strings like this. I'm open to change format of values for body field.
parsing any delimited string (in above example it is using ',' as parsing delimiter. This query can be useful in many business scenarios where in we have input data as a long string containing delimited values.

I have a co-worker who applied build 3161 to SQL Server 2005. The original problem was that the print preview was showing up as black.This is a documented issue with Microsoft here:
http://support.microsoft.com/kb/935436
Now, when she goes into expression builder, the foreground AND background color for what you type in there appears to be white... so everything shows up as invisible. You can highlight the text you type and it shows up but otherwise it is obviously invisible.
The suggestion to do this is buried deep in one of my posts, however I still do not have a clear idea of how to do this.
I have a flat file which has several "bad rows" in it. Because file error redirection is buggy, I need a manual approach to get rid of these incomplete rows in my data file.
Phil, you suggested I read the file as one long string, then parse out the bad rows (using a script?).... however I have no idea as to how to actually do this.
I was wondering if it's possible to clarify the steps involved in doing this, or perhaps point me to an example I can look at, as I cannot seem to get around this problem on my own.
My colleague opens up an SSIS package with variables, many of which use expressions built with the Expression Builder. She cannot bring up the Expression Builder by clicking the ellipsis (...) in the "Expression" Property of the Property Window, regardless of whether "EvaluateAsExpression" is set to True or False.
I can open up this same package and use the Expression Builder just fine. Any ideas?
Apologies if this has been answered already, I did many searches to try to find the solution before posting here.
I have implemented a custom source component that can be used as the data source in the Data Flow task.
I have also created a custom UI for this component by using the IDtsComponentUI .
But my component does not have the capability of setting the custom properties via the DTS Variables using the Expression Builder.
I have looked around for samples on how to do this, but I can only find samples of how to do this for custom Control Tasks, i.e. IDtsTaskUI.
My question is, How can implement the Expression Builder in my custom Source component + custom Source UI. Or do you know of any samples which I can look at.
How do you write an expression in report builder to only display the results that start with a certain string value..eg. Project Number - CUP1501, DPR1502, ENG1507 etc. These values will all get returned but I only want the Project Number that has CUP and DPR in it?
Wondering what's the preferred method for this. I've got a scenario that a user is updating some content on a page and I need to update my word catalogs for my search feature. I have some code currently to filter out words that are too small, make sure there are no duplicates and to count how many occurrences there are of each. What I'm wondering is, does it make more sense to do a loop in my code to run all the insert commands to place the new words in the database, should I try sticking them together in one string and parse them when they get up there or is there a better method someone can suggest?
I'm trying to parse out a line of data that is separated by the text "atc1.", "atc2." etc.
For example,
[atc1.123/atc2.456/atc3.789/atc4.xyz/]
If I only want the data after atc2., then I could search the string for "atc2." and collect all the characters afterwards. But how can I make sure to trim off all the data after "atc3." to make sure I'm only collecting "456" from the example above?
I have a problem at the moment, where the client wants to be able to type in a custom algebraic formula with add/minus operators, and then to have this interpreted, so that the related datasets are then added and returned as a single dataset.
An example would be having a formula stored of [a] + [b] - [c]
and if I were to write the SQL to apply that formula, I might write something like (let's assume 1:1 relationships with the ID's)
select a.a + b.b - c.c as [result] from z inner join tblA a on z.id = a.id inner join tblB b on z.id = b.id inner join tblC c on z.id = c.id
The formula can change though, maybe things like:
[a] + [b] + [c] + [d] [a] + [b]
The developer before me wrote something SQL-based where they parsed the string and assigned each value of the formula as either positive or negative (e.g A is positive, B is positive, C is negative, now sum the datasets to get the result), and then created one large table of values then summed them. This does (kind of) work, I'm just contemplating potential alternatives, as it is quite a slow process, and feels like it is quite convoluted, when I get into the details. If I were to do something like this in SQL, I'd normally want each part of the expression to be a column, and then to just apply the operators, but because the formula can change, then the SQL would need to be somehow dynamic for this approach.
I have a table which has expression as a column and the data looks similar to the following .
ID (int) Expression (nvarchar data type)
1 8*(1/2)-6
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
