Truncate Decimal In Derived Column Task
Apr 10, 2008Hi,
Is there a way to truncate a number to a certain number of decimal places in the SSIS Derived Column component (similar to TRUNC in excel)?
Thanks!

Adding Implied Decimal Without A Derived Column From Flat File Datasource
Apr 18, 2007We are importing Flat file data from our Mainframe system. We have a lot of money amounts coming in, but the mainframe does not store the decimals in the flat file. So for example a row in the file might look like this:
+0000007894-0000000563
Where the first value is $78.94 and the second value is -$5.63
Is there anyway to have the Flat file connection manager put in the decimal place for me, or do i have to create derived columns for each column and divide it by 100? There like 50-100 columns per file, so i'm looking for a better, quicker way.
Thanks in advance.

Integration Services :: Add New Column Based On Existing Column Using Derived Column Task?
Jul 28, 2015I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A
B

If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
Derived Column Task Replace Quotes
May 14, 2007How do you replace quotes in an expression
I mean for example if I needed to replace xx in a string with empty string then the following works: REPLACE(SelectedString, "xx","")
But the example I have needs to actually replace quote marks in a string with an empty string and REPLACE(SelectedString, " " ","") doesn't work. I tried guessing a few option like "E or &QTE or something...
Any ideas ?

I'm Retarded And Need Help With Derived Column Or Script Task
Feb 2, 2006I am moving data from an oracle database to sql server. Two of the source fields are dates, which sometimes contain values I know to be incorrect ('0001/01/01' and '1900/01/01').
I'd like to use either the derived column or script task (or any other appropriate one) to update these incorrect values (in both columns) to null before inserting into sql server, smalldatetime field.
In sql 2000 dts, I would simply use a VBScript IF statement, but I'm somewhat clueless when it comes to .Net.
Does anyone have any ideas or sample code that may help?
Thank you much.
Derived Column Task Failing With Error 0xC0049067
Apr 20, 2006I have a package that fails as soon as it hits the first Data Flow that contains a Derived Column task. The task takes three date columns and looks for a date of 6/6/2079. If it is there, it is replaced with a NULL. This task worked fine until I installed the Non-CTP version of SQL 2005 SP1, earlier today. (I went from RTM 9.0.1399 to SP1 9.0.2047)Does anyone have any ideas?
Here is the error I am trapping:
An error occurred while evaluating the function.
The "component "Update Max Date Value to NULL" (346)" failed because error code 0xC0049067 occurred, and the error row disposition on "input column "WeekEndingDate" (455)" specifies failure on error. An error occurred on the specified object of the specified component.
The ProcessInput method on component "Update Max Date Value to NULL" (346) failed with error code 0xC0209029. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
Thread "WorkThread0" has exited with error code 0xC0209029.
I tried to configure the error output to ignore the failure. The task succeeded. It did not insert anything, however, for the three columns in question. It then failed on the next Data Flow that contained a Derived Column task. I tried to pre-populate the columns with a default date, but no go. Any help would be appreciated.
Ho Do I Get The Details From A DTS Transform Data Task Into An SSIS Derived Column Transformation?
Mar 7, 2008i have too many DTS packages to migrate to SSIS, and while examining a DTS package in BIDS (converted with the migration utility) i tried to edit the resulting migrated package, which opened the DTS interface with the two connection icons joined by the big fat arrow with a gear on it...not exactly what i had in mind, iow, it looks like SSIS on the outside, but its still DTS on the inside.
So I stripped out a series of components from a more complex package hoping that simplifying it would reveal the contents of old DTS Transformations tab at least partially set up in a Derived Column transformation.
Can i get there from here, or must i recreate every stinking definition in a derived column manually from the ground up?
thanks very much for your help
How To Assign User Variable Value To The Derived Column, In Data Flow Task
Dec 19, 2006Hi:
In the derived column transformation editor, I have a Derived column name called FileGroupID. I would like to pass in a value for this column from a variable that I have set earlier in the scope. Can someone let me know, how to write the expression that does that and where do I specifiy that expression. I am thinking its the expression field in the derived column transformation editor. My main question is how to actually write the expression, what is the syntax to pull the variable value? Thanks.

Truncate Log As Maintenance Task
Jun 23, 2008In my maintenance plan task I have added a final step, an execute T-SQL statement, the code is simple, just a truncate of the database log to free space in the server, the code I am using is this on:
use NAV001
GO
DBCC SHRINKFILE(NAV001_Log, 1)
BACKUP LOG NAV001 WITH TRUNCATE_ONLY
DBCC SHRINKFILE(NAV001_Log, 1)
The problem is that I get an error when the maintenance task reach this step, the error log says that:
DBCC SHRINKFILE(NAVISION_PRUEBAS_Log, 1)" failed with the following error: "Could not locate file 'NAV001_Log' for database 'master' in sys.database_files. The file either does not exist, or was dropped.
Why is it trying to use master database if I am telling sql server to "use NAV001" in the first sentence?
Cast/Convert Mmddyy In String To New DB_DATETIMESTAMP Column In Derived Column Transformation
Mar 5, 2007Hi,
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)
Sep 11, 2007
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!

Access To TaskHost From Derived Task Class.

for some reasons, I have to get access to the TaskHost during validation and execution. For example, I wanna know, if my task is within a container or not (parent is Sequence).
For the UI during design time, there is the TaskHost parameter. What about the execution time or during validation?
Any hints?

Add Values To A Column With Derived Column Expression?
Feb 25, 2008Hi, 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.

Transfer Sql Server Objects Task Truncate Table Fails Due To Foreign Key
Aug 10, 2006Hi
We used to used Sql Server 2000 DTS to perform daily backups to remote servers very successfully but just cannot do the same with SSIS.
I set my Transfer Sql Transfer Objects Task to use the following settings:
CopyData = true
ObjectsTocopy = All Tables
As soon as it hits a table that has a foreign key, I get the following error:
"Truncate data failed for Table nnn"
I've tried setting DropObjectsFirst = True but this fails too with foreign key violations.
First of all, am I doing something obviously wrong? Is SSIS not smart enough to drop tables in the right order so that we don't get foreign key violations?
Am I totally barking up the wrong tree with this and can anyone suggest a better way of doing remote backups?
Kind regards

Adding Decimal Value During Data Flow Task
Nov 19, 2006Hi,
I have a flat file(pipe delimited), like below( only two rows shown)
1|001|B|C|002|A|003|
1|005|D|C|003|A|004|
I have to import column 2( that is 001), column 5 (that is 002), column 7(that is 003) from the above flat file to column in Database that has DataType Numeric DataTyp (4,3).
In the Database the columns shoule have values like(.001), (.002), (.007). I have used flat file source, Script component, and OleDbDesitnation in my DataFlow task.
In the script component, I have added a "." for each column as a string.
I cannot import to OldeDbDestination becuase of Data conversion issue.
Is there any way we can solve this..
Thank you.

Execute SQl Task Return Decimal Type Result
Dec 3, 2007
I am trying to have an Excecute SQL Task return a single row result set executed on SQL Server 2005.
The query in the Execute SQL Task is:
select 735.234, 2454.123
I get a conversion error when trying to assign to SSIS variables of type Double.
I have nothing configured in the "Parameter Mapping" tab.
I have the two SSIS Double variables mapped to the Tesult Name 0 and 1 in the "Result Set" tab
I don't want to use a for loop enumerator since there is a single row returned.
I simply want to assign these two values to SSIS Double variables (double is the closest match)
I can't even hack this by converting the decimals as string and then using DirectCast to convert them to Double.
Thanks for the help
Truncate Characters In A Column
Jan 26, 2006I recieve data where I am comparing zip codes from raw data, to a zip code table. The columns I am matching are in integers.
The issue is that in the raw data, sometimes the zip code is extended to more than the 5 characters in the zip code table so I am getting null value returns
A sample of this is in the raw data is:
Zipcode
54303
54304786
78641
Is there a way I can have it compare only the first 5 digits of the zip codes in the raw data zip code column to the zip code table? Or would I have to convert the data type? Or alter or truncate the characters somehow? If so, please include how to do this. Any help would be greatly appreciated. Thank you!
Derived Column
May 6, 2008Hi, wondering if anyone can help me. I currently have a field that has a date and time in it in the format dd/mm/yyyy hh:mm:ss. Ideally I would like to get rid of the time part of it altogether but for it to still be recognised as a date as opposed to a string. However, I've been told that this is not possible in 2005, is this true? If this is the case, what would be the best way to set the time to 00:00:00 after the date for all records on that field?

Deriving A New Column From Another Derived Column
Jul 26, 2006In 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?
Conditional On A Derived Column
Jan 27, 2006Hi 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.
SSIS Derived Column
Mar 6, 2013Two questions regarding Derived Columns in SSIS
1. In a if else expression if condition is false how do you keep the value of the source column eg: Name == "" ? "Unknown" : Name
Above will change all the non blank values to Name and not the actual value
in the Name Column eg. John
2. I have a column (unicode string)that stores date and time (The source is flat file) Is it possible to write expression to select the 1st day of month based on that date, and use this derived column as input to a table with a datetime field.
