Validating Date Via An Derived Filed/expression
Apr 8, 2008How can I validate the date that is coming across in a 8 byte character field via an expression? It will either be a valid date or 0. If it is zero I want to make it a null.

Default Date In A Derived Column Expression
Nov 20, 2006one of my SSIS packages use this expression to put todays date in if it is NULL:
(ISNULL(datejs)) ? GETDATE() : datejs
however, what I really want to do though is put a default date in like '2007-01-01' but I get syntax error because SSIS thinks it's a string, which it is I suppose.
Is it possible to do what I want it to?
Thanks
Date Issue With Derived Column / Expression Language
Jan 10, 2006Can someone confirm this for me? The expression language in SSIS has the same limitations on date ranges as Sql Server? That limitation is that valid date ranges are from Jan 1, 1753 to Dec 31, 9999.
When ever I try to do a date function (DATEPART, for example) in a Derived Column Transformation on a date less than 1/1/1753, I get an error. I initially discovered this when bringing data over from Oracle to Sql Server. Just as a test, I created a text file filled with various dates and tried to import it. Whenever a date is less than 1/1/1753, it blows up.
For example, this expression code - DATEPART("YEAR",Date) will yield this error - [Derived Column [24]] Error: The "component "Derived Column" (24)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "YEAR" (80)" specifies failure on error. An error occurred on the specified object of the specified component.
As a workaround, I've been using a Script Component to do date checking, but this is obviously not ideal.

Jan 31, 2007I have a table in my report which shows sales values for each month by looking at the month number
so for Jan i use
=IIf(Fields!period_.Value=1,Fields!nett_.Value,0)
for Feb
=IIf(Fields!period_.Value=2,Fields!nett_.Value,0)
this is all good and I get a series of rows per customer with the correct value in the correct column
JAN FEB Mar
Customer A 250
Customer A 350
Customer A 5000
.
However I want to create a summary a line
JAN FEB Mar
Customer A 250 350 5000
I tried using SUM but this doesn't give all of the values in the summary line. It might just give the first and the rest are zeros. Or if the customer didn't have a value in Jan, but did in Feb and March, Feb's value is shown, but March is at 0 etc.
Have spent far too long on this today, so if anyone as any suggestion (come back Crystal all is forgiven ) on any approach I could take to this I'd appreciate it.

Question On Derived Column Expression
Apr 30, 2007Hi, all experts here,
Thank you very much for your kind attention.
I am having a question on derived column expression. The expression I am trying to use for the derived column is as below (column1 is a numeric data type column):
case
when column1<0 then 'yes'
else 'no'
end
But I got the error message though, would please any experts here give me any advices on the expression I used? What is wrong with the expression I used above?
Thank you very much and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,
Derived Column: Expression Question
Dec 4, 2006The following simple expression is not working for in a derived column transform. I have tried several things back and forth with lots of frustration.
DAY((DT_DATE)mydate)
In fact any of the date/time functions are not working for me and I keep getting the following error
[Derived Column [380]] Error: The "component "Derived Column" (380)"
failed because error code 0xC0049067 occurred, and the error row
disposition on "output column "Derived Column 1" (824)" specifies
failure on error. An error occurred on the specified object of the specified component.
mydate happens to be imported as string[DT_STR] column from a flat file source.
Thank you in advance.
Derived Column Transformation Expression
Mar 7, 2006Hi.
I am using the following expression to check if the first charcter of a string is not the letter "E" and if it is, strip it off by selecting the remainder of the string:
SUBSTRING([Derv.comno],1,1) == "E" ? SUBSTRING([Derv.comno],2,10) : [Derv.comno]
This is ok in 99.9% of cases, but ideally I would like to be able to check, and alter the string if the first charcter is anything but numeric
I had something like this in mind:
SUBSTRING([Derv.comno],1,1) != ("1","2","3") ? SUBSTRING([Derv.comno],2,10) : [Derv.comno]
but the syntax is incorrect.
Could you tell me if what I am attempting is actually possible, and if so, point me in the right direction regarding the syntax!
Thanks

Derived Column Expression Question......
May 7, 2007Greetings,
I have an existing 2000 DTS package that uses the following case statement:
Case
When TERMS_PERCENT ='0'
then 0
else cast(TERMS_PERCENT as decimal(6,2))/100
end as TermsPct
to convert a source DT_STR(4) datatype to a DT_Numeric(5,2) destination column and would like to use an equivelent derived column expression in 2005. Being a DBA by nature and experience I'm having trouble converting this statement to a valid expression without failure, any help would be greatly appreciated.

UDF Or Trigonometric Functions In An Expression For A Derived Column?
May 24, 2006Hi all!
I am importing data from a CSV to a DB with a SSIS package.
Among some things things it already does, it has to decide if the relation between one row and the following is acceptable.
If it is not, the 2nd row is discarded, the next one is taken and the relation value is calculated again to decide whether to keep this one or not, and so on.
To calculate this value, I need to apply a formula that includes sin(), cos() and acos() functions.
I have already written this formula as a scalar-valued function in my SQL Server.
So, my question is:
- Is there a way to call a function (a UDF) within the Expression in a Derived Column dataflow item?
and if not,
- Hoy can I use trigonometric functions within the Expression in a Derived Column dataflow item?
I hope someona can tell me something about this... I'm falling into despair! :-s
Thanks a lot!!

Expression Problem In Derived Column Component
Nov 22, 2006I am reading an excel file with a field that consists of lastname, firstname. I am using the Derived Column transformation to separate the two fields. The firstname expression works fine: SUBSTRING(F1,FINDSTRING(F1,",",1) + 1,LEN(F1) - FINDSTRING(F1,",",1))
However, the lastname field keeps giving me an error when I use SUBSTRING(F1,1,FINDSTRING(F1,",",1) - 1). I'm sure I've used this substring before in visual studio. Could this be a bug? The error is below.
[Add Columns [2886]] Error: The "component "Add Columns" (2886)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "LastName" (3100)" specifies failure on error. An error occurred on the specified object of the specified component.

Validating A Date Masked As A String.
Jul 8, 2006I'm trying to import a text file with a column that is actually a date value, like this "19550218" (yyyymmdd).
What is the best way to test if the string-date values in this column represent valid sql dates? Should I use SSIS to copy that value into an actual sql date field and see if an error is generated? I have tried using the VB.NET
"System.Datetime.ParseExact"
function in a Script task but found ParseExact less than reliable.
TIA,
Barkingdog
P.S. In fact, thought not speedy, I think that SSIS should come with a number of datatype validation routines "out of the box". Importing clean data is relatvely easy. It's handling the exceptional cases, like above, that really burn up my time.
P.P.S An before some says "regular expressions" I don't know enough about them to use them wisely.
Is Pattern Matching Possible In Derived Columns Expression Syntax?
Feb 8, 2008
Chaps,
apologies for the drip-drip approach......
Is it possible to do pattern matching against a string using FINDSTRING or similar in a derived column expression without recourse to including 3rd party regexp style plugins?
I want to seach for a reference in a string which will have the format ANNNNNAAA ie. an alpha with a certain value followed by 5 digits followed by three alphas with specific values.
eg Z00001YYY or X00022HHH
thanks for your assistance,

Major Problem With REPLACE-expression In The Derived Column Transformation
Apr 26, 2006I'm importing a csv-file delimited with semicolons. Firstly I LTRIM the columns "in place" and the data imports fine. All the numbers in right columns in the target table. Then I add another Derived Colum Transformation to replace decimal character comma (,) to a dot (.) in order to convert the string/varchar value to numeric. But here I run into trouble. Running the task ends in success but the result in the target table (same as above) is not. All the commas are now dots as expected but what is worse is that SSIS have added values in cells that should not be there. I get values in cells that shoud be empty!
Shortly: Only LTRIM([Column1]) as expression and "Derived Column" as Replace 'Column1' works OK.
But adding REPLACE-expression (i.e REPLACE(LTRIM([Column1]) , "," , ".") to this breaks things up
I'm aware that I could do this with SQL but this is not the point...
Any ideas?

But at end of result i got all the columns as No. Some should be Yes.
Newbie Case/search Question In Derived Column Expression Syntax
Feb 6, 2008
Hi everyone,
I am a newbie to SSIS and looking for answer to a simple search/replace style question.
I am building a derived column and looking for some expression syntax that can search for several strings in one column and set a value in a new column.
A bit like a case statement:
CASE ProductLine
WHEN 'R1' THEN 'Road'
WHEN 'M1' THEN 'Mountain'
WHEN 'T1' THEN 'Touring'
WHEN 'S1' THEN 'Other sale items'
ELSE 'Not for sale'
END,
The twist is that 'R1','M1','T1','S1' could feature anywhere in the string that is ProductLine.
Thanks for all your help,
regards,
Chris

Newbie Search/replace Case Style Functionality In Derived Column Expression Syntax

Hi guys,
I am looking for some syntax to help me with a traditional search/replace style requirement. I am wanting to examine the contents of one column and populate another.

WHEN 'R1' THEN 'Road'
WHEN 'M1' THEN 'Mountain'
WHEN 'T1' THEN 'Touring'
WHEN 'S2' THEN 'Other sale items'
ELSE 'Not for sale'

the twist is that R1, M1 etc. can appear anywhere in the ProductLine column.
thanks for any assistance you can provide.

Derived Column - Date Conversions?!?
May 1, 2007It was my understanding earlier that -- it is mandatory to have a Derived Column for a DATE String in a Flat File
to be loaded properly into a table with "datetime" column type
However, i tried running my package with the Input Column as "DT_STR" and the Destination on the table is DATETIME.
Looks like the process went on fine.. Am i missing something here?
My Date Format from the source looks like -- "DD-MON-YY"
