SSIS-Expression Builder
Apr 18, 2008
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

This works:
len ((DT_WSTR,2)DATEPART("mm", getdate()))==1 ? (DT_WSTR,1)0 + (DT_WSTR,1)DATEPART("mm", getdate()) : (DT_WSTR,4)DATEPART("mm", getdate())
This doesn't:
"dataware/"+ len ((DT_WSTR,2)DATEPART("mm", getdate()))==1 ? (DT_WSTR,1)0 + (DT_WSTR,1)DATEPART("mm", getdate()) : (DT_WSTR,4)DATEPART("mm", getdate())
I tried a couple of different things at this point, where am I missing the cast? Before len? Cast to what?

Hi,
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.
Thank you,
Jameel.

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 = '.......'
END
Thank you.

Hi all of you,
When you're making expressions with your own variables and system variables and so on. How could I see the contents for each variable?
When you have an expression like this:
"Cargas de Hacienda. " + SUBSTRING( @[System:ackageName], 7,20) + " "
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.
Thanks for any input or advice,
Enric

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.

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?
Thank you for your help!

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.
Is this possible?

Hello,
I am using the following expression to access a daily file.
"D:\importdata\peregrinedata\ACD_DATA_" + (DT_WSTR, 4) YEAR( GETDATE() ) + (DT_WSTR, 2)MONTH( GETDATE() ) + (DT_WSTR, 2) DAY( GETDATE() ) + ".txt"
output: D:importdataperegrinedataACD_DATA_2008123.txt
I need to have this file by current day -1. I've tried dateadd and can't figure out how to get it to work.
Thanks

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.
Anyone know how to fix this?

Has anyone encountered this before?
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.
Thanks much!

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?

Hi all of you,
That's an easy one. I've got a Send Mail task which might send a message in plain text along with a SSIS variable.
Something like that:
'La tabla "' + SUBSTRING( @[System:ackageName], 3,20) + "' se ha cargado correctamente'
TIA for that,

I am developing the SSIS and stuck on copying specific files.
1. We receive CSV file to our drive on a daily basis.
2. The csv file name has the last 8 digits formatted with the yyyymmdd. For example, the file name might be abcdef_20150226.csv This means it will be our CSV file for today, Thursday, February 26, 2015.
3. There are a lot of files in this directory.
[URL]
What we would like to do:
Add the constraints (or expression) that will copy the files from this directory to another directory that have the date equivalent to Monday only. For example, the file abcdef_20150226.csv will not be copied because it is Thursday file. But the abcdec_20150223 will be copied to a new Directory because it is Monday.

I have a file named abc-72015.txt.
I have a package that renames the file from abc.txt to abc-72015.txt
I want to do the reverse. I wan to rename it from abc-72015.txt to abc.txt.
I have a variable named myFileValue with a value of abc.txt.
Can I do this by setting the variable as an expressions and use a function to rename it as abc.txt?
What would the syntax be?

I have a package with an input column that is varchar(8000).
I want to strip the first byte off of this column and put it in one result column and the remainder of the field I want to go to a second column. If the input column is an empty string, I want to return NULL.
Pulling the first byte off works fine, no issues, however putting the remainder of the input column into an output column is giving me a little trouble.
If I use this expression:
LEN(FLD1) == 0 ? NULL(DT_WSTR,1) : SUBSTRING(FLD1, 2, LEN(FLD1) - 1))
I get an error that says my expression evaluates to a string of greater than 4000 bytes.
If I do this instead:
LEN(FLD1) == 0 ? NULL(DT_WSTR,1) : RTRIM(SUBSTRING(FLD1, 2, 7999))
The expression passes muster but I get the warning that I will be truncating the column at 4000 bytes.
In actuality, I don't care if the result column is truncated after 4000 bytes. I find the second solution to be a bit clunky and I'm wondering if anyone can give me a reason why the first solution won't evaluate but the second will?

Ive been using SSIS for a month or two and now find I need to create some custom tasks to perform some performance logging. in the the overloaded ProviderComponentProperties section I am trying to create a property which has the same look as the Expressions properties you find elsewhere (Little + on the left and a group of sub properties when expanded).
Ive have played with creating a IDTSCustomPropertyCollection90 collection then adding my sub properties to it but I cant seem to then add my new collection to the ComponentMetaData.CustomPropertiesCollection.
Im assuming the Expressions parameter is a collection added to the properties collection but I cant figure out how. Any help would be much appreciated.

I am using the "XML Source Adapter" in an SSIS package.
I notice that although you can specify the XML filename as an expression, the XSD appears to have to be a fixed file path.
This is a problem for me since the path for the XSD is different in my development than it will be in production (in production it's on drive E:, which I don't have).
I'd like to have the file location specified in the config file, but since I can't make it an expression how can I do that?
Also, since they don't have Connection Managers I can't switch DelayValidation on.
Thanks.
