Derived Column Can't Add 8-byte Integers
I'm having trouble adding a 4-byte integer with an 8-byte integer. Here's what I'm doing:
Column Name: BIG_ID
Derived Column: < add as new column >
Expression: (DT_I8)[ID] + 840230000538058
Data Type: eight-byte signed integer {DT_I8]
The error I get:
The literal 840230000538058 is too large to fit into type DT_I4. The magnitude of the literal overflows the type.
Then I try the expression:
(DT_I8)[ID] + (DT_I8)840230000538058
and
[ID] + 840230000538058
and get the same error.
What am I doing wrong? Is it possible to add 2 8-byte integers in regular expression? Why does it still think the literal is DT_I4?
Thanks,
Michael

Cast/Convert Mmddyy In String To New DB_DATETIMESTAMP Column In Derived Column Transformation
Hi, I have dates in "mmddyy" format coming from the sources and they are older dates of mid 80s like 082580 for instance. When I cast it this way (DT_DBTIMESTAMP) Source_Date , It says ok but throws a runtime error. When I hardcode a date in same format, (DT_DBTIMESTAMP) "082580" , It becomes red (an indication of syntax error) . Please note that we use double quotes in expressions in Derived Column Transformation; So an anticipation that using double quotes over single ones would be the syntax problem would be wrong. Any help in this will sincerely be appreciated. Thanks

Derived Column Usage When Column Does Not Exist In Source (but Exists In Destination)
Posted - 09/10/2007 : 15:53:26 Hey all - got a problem that seems like it would be simple (and probably is : ) I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me. Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs: '********************************************************************** ' Visual Basic Transformation Script '************************************************************************ ' Copy each source column to the destination column Function Main() DTSDestination("CM") = Month(Now) DTSDestination("CY") = Year(Now) DTSDestination("Comments") = DTSSource("Col031") DTSDestination("Manufacturer") = DTSSource("Col030") DTSDestination("Model") = DTSSource("Col029") DTSDestination("Last Check-in Date") = DTSSource("Col028") Main = DTSTransformStat_OK End Function *********************************************************** Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data. thanks in advance! jm

Add Values To A Column With Derived Column Expression?
Hi, how are you? I'm having a problem and I don't know if it can be solved with a derived column expression. This is the problem: We are looking data in a a sql database. We are writting the SQL result in a flat file. We need to transform data in one of the columns. For example: we can have 3 digits as value in a column but that column must be 10 digit length. So we have to complete all the missing digits with a zero. So, that column will have the original 3 digits and 7 zeros. How we can do that tranformation? We must do it from de the flat file or it can be a previous step? Thanks for any help you can give me. Regards, Beli

Deriving A New Column From Another Derived Column
In a Derived Column data flow transformation, why can't I refer to a derived column (added in that same transformation) in the expression for another derived column? It seems I am forced to chain 2 DC data flows, just to do something as conceptually simple as: a = x + y; b = a² On a related note: Can I define a variable that is scoped to each row? Can I bind a variable in an expression to avoid creating a new row, e.g. let a = x + y; a² as the expression for new row b?

When I run the bcp, it runs successfully, but the valueinserted into col1 is always NULL. I modified my trigger to get abetter idea of what was happening, and when I look at the values ofINSERTED.col1, they are all null. It appears that bcp is setting thecolumn value to null, presumable because the view definintion for thiscolumn is a derived column.Does any one know a way around this?Thanks!

Conditional On A Derived Column
Hi everyone, I have a quizzing application where users log in, answer questions, and are ranked relative to each other. For this final ranking, I calculate their score using this formula - score = (correct Qs answered) * 150 / (total Qs answered) + (total Qs answered) The SQL query that i use to get this info is - Code: SELECT TOP 50 username, (sum(correct) * 150 / count(1) + count(1)) AS score, count(1) as totalq FROM questionsstats GROUP BY username ORDER BY score DESC This works just fine. However, on top of this I need to put an additional restriction that only users who have at least answered 20 questions be counted in. How can I do this? Adding a simple 'WHERE totalq > 20' does not work. I get the error "Invalid column name 'totalq'.". Surely there must be a simple way to do this? Thanks.

Derived Column From A Condition Statement
I've found that there is no such thing as a Case Statement in the Derived Column task in the data flow objects. I've written a ternary statement instead. I can't seem to get it to work exactly how I want it to. For example AccountCategory == "E" ? 1 : 2 Works fine but the following doesn't AccountCategory == "E" ? CreditAmount : DebitAmount The CreditAmount and DebitAmount Fields are spelled correctly, the field type of AccountCategory is String and the Field type of CreditAmount and DebitAmount is numeric, but that seems to be the same situation that I have in the first example that works. Am I missing something? I'd appreciate any advice anyone has to offer. Thanks, Bill

Using OLE DB Source Properties In Derived Column

Does anyone know how I can do this? Any help much appreciated. Thanks

Derived Shape - Replacing A Column With Itself.
Hi there, I have a derived column shape in which I replace a column with an expression. The expression is an IF statement - a true result sets a value for the column and a false result just uses the existing value of the column (ie it replaces it with itself) Like this. ColumnName DerivedColumn Expression ColumnA Replace 'ColumnA' ColumnB != ColumnC ? "y" : ColumnA But whenever, the condition is NOT met, ColumnA is set to NULL!!!! Does this mean that the column value is deleted before the Expression is applied? If this is how it is meant to work, then does anyone have a way of doing what I want to do without creating extra columns in the dataset?? Cheers.
