It 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"

I'm reading a .csv file that has a column such as 17June2007:00:00:00, how can I convert this column in my Derived Column routine so its inserted into my DateTime column in my database?
so far I've tried
DT_DateTimeStamp
DT_Date
DT_DBDate
DT_DbTime
and its kicking back errors on this column. What do I have to do to convert 17June2007:00:00:00 into a readable datetime for the database column?
I'm having trouble converting a date in the format of:
Jan 11 2006 12:00:00:000AM
to a smalldatetime in my new SSIS package. I'm trying the derived column transformation, but I'm at a wall now, especially with the conversion of 'Jan' string to integer/month/value of 1. Anyone have experience/advice on this transformation?
What happened to the DateTime String transformation in SQL 2000? Was that too unpopular to move to integration services? That transformation saved my butt many times - every banks' data feed we import uses a different date format.
Thanks in advance for any advice/help!

how to declare multiple derived columns in SSIS Derived Column Task in one attempt.as i have around 150 columns coming from Flat file. I had created the required Expression in Excel and now i want add those in derived column task but its allowing only 1 expression at a time.

Hi,
Is there a way using a derived column transformation to change the format of the date eg:
The input flat file's date is in yyyy/mm/dd and i need to convert / change this to yyyy/dd/mm
Is this possible?
Thanks in advance,
Slash.
one 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
So I am trying to change my date type which is in the 1/1/2015 12:30:10 PM to a 2015-1-1 00:00:00
So I am using Derived Columns to do the trnasformation in Visual Studio but I am getting the following error:
An error occurred while attempting to perform a typecast
So this is what I did
Step 1:
Load date into OLE DB Source
Step 2:
Replace function
REPLACE(ATL,"1/1/2015 12:30:10", "1900-01-01 00:00:00)
Step 3:
Replace Function
REPLACE(ATL,"/","-"0
Step 4:
Replace funtion
REPLACE(REPLACE(ATL, "AM",":00"),"PM",":00"
Step 5: this is where the error occurs
(DT_DBTIMESTAMP)ATL
Step 6:
Load into OLE DB Destination File
Can 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.
Hi All, I struck by a issue, In a table(tblMemberPayments) i had two columns one is to hold (month) as CHAR and other one is to hold (year) as INT. Now i need to implement search for this table based on the dates given , I mean i need to get the records from this table in between any two dates given by the user (Eg : feb 2007 to feb 2008). While retriving i am unable to type cast the things as required for the above case. I am getting an error unable to convert varchar to datetime while using CONVERT FUNCTION the same thing a raises while using DATEDIFF FUNCTION .help me if any one knows the solution . here are the couple of ways i tried 1) 'CONVERT(varchar(10),(tblMemberPayments.ExpirationMonth + tblMemberPayments.Expirationyear),1) between CONVERT(varchar(10),''feb 2007'',1) AND CONVERT(varchar(10),''feb 2008'',1)' Msg 245, Level 16, State 1, Line 1Conversion failed when converting the varchar value 'Apr' to data type int. 2)'datediff(m,Cast(tblMemberPayments.ExpirationMonth + tblMemberPayments.ExpirationMonthint as datetime), ''Feb 2008'') >= 0 and datediff(m, cast(tblMemberPayments.ExpirationMonth + tblMemberPayments.ExpirationMonthint as datetime), ''Feb 2007'') <= 0' Thanks & Regards, Sudheer.Y

declere @d varchar(10)
declare @t varchar(10)
set @d=convert(varchar,'7/25/2007 10:10:53',101)
set @d=convert(varchar,'7/25/2007 10:10:53',108)
it returns as
@d=7/25/2007
@t=7/25/2007
but @t should be equal to 10:10:53
what's wrong in the conversions

View 2 Replies View RelatedHaving some trouble converting strings to dates. I am using a .dtsx package and have figured out how to use a derived column to convert the string to a new string which is a valid date. The problem is now converting the column data type to date. I insert a new data conversion step to convert the vchar field to date, then when it runs it fails on this step. Error is
The conversion returned status value 2 and status text "The value could
not be converted because of a potential loss of data."
If I leave out the data conversion step and run the package, then manually change the data type to date it warns with the same message, but if I accept it converts correctly.
Here is my derived column code
REPLACE(SUBSTRING([Data Conversion 1].START_OF_EXECUTION,1,10) + " " +
RIGHT([Data Conversion 1].START_OF_EXECUTION,8),".",":")
Please Help
Hi
I am quite new to SSIS and have been given the task of importing some data from a text file into the database. The data contains dates which are in the American format of mm/dd/yyyy. I need them in the datadase in the format of dd mon yy.
I realise I could load it and do a SQL task to convert once it is in the database but ideally i would like this data transformed before it is loaded into the tables.
any suggestions will be gratefully recieved.
Best regards
I have this query where I do certain conversions and on top of this how can I sum the column values.
'$ '+ Replace(CONVERT(varchar,CAST(Total_Amount AS money),1) ,'.00','') as Total_Amount,
'$ '+ Replace(CONVERT(varchar,CAST(Monthly_Amount As money),1),'.00','') as Monthly_Amount,
I have multiple columns in a table that I only want to convert if they are not null or of the proper type. I don't really want to redirect the whole row if one of the conversions fails, rather I would just not want to do the cast or set it to another value. In this scenario is it better to use a custom script or multiple tasks? The multiple tasks seems like a lot of overhead for processing the same data. Just curious how others handle this scenario as it seems as though it has come up quite often on our current project? Thanks for the assistance.

PS: Is it possible to embed evaluation statements along with conversion statements in a task expression? e.g. (len(trim([Column1])) > 0) substring([Column1], 1, 4)
I 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
C
D
E
F
G
H
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".
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

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!

Table structure as follows
Employee
Empno empname salary
commission
I want to have an other employee table named employee_modified
Empno empname salary
commission derived_column1(salary+commission)
derived_column2(derived_column1 + xxxx) and so on derive other
columns based on the earlier derived columns)
Is that possible to do it.. or am I doing something wrong.
something like
Select empno , empname , salary , commission,
(salary + commission) as derived_colum1 ,
(derived_colum1 + xxxxx) as derived_colum2 ,
(derived_colum2 + xxxxx) as derived_colum3
into employee_modified from employee
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
How 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.
View 1 Replies View RelatedHi, 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?

I am trying to transfer data from SQL Server 2005 table to another SQL Table. In the source table there is a field called Region [nvarchar(max)]. The values for these fields will be like APAC-China, NA-Racine, etc., i.e Region followed by the country name seperated by - symbol. I want the destination tablre with 2 fields Region[nvarchar(max)] and Country [nvarchar(max)]. I am using a Derived Column task to achieve the same.
Can anyone please help me out in doing this data conversion?
Thanks
Hi,
I am doing a task which will get all data based on several base and crosswork tables. I used stored procedure to get the data, but the next step will be using derived column to massaging data, and to load to the destination database. Is there a way to do that since I must generate data on the fly?
Thanks,

I am trying to create a derived column from two separate fields. One is a date field in format of 2008-03-01 and one is a time field. In DTS I use to have something like this:
DTSDestination("TransactionDate") = cdate(DTSSource("DSRHDATI")) & " " & timevalue(DTSSource("DSRHTIME"))
I am trying to figure out how to do this in SSIS. I know I have to use a dervived column but can't seem to come up with the correct syntax. Any help would be apprecaited. thanks.

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?
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.
Two 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.
Hello, first time here, first time messing with SQL.
When creating a table in SQLServer2005 can you specify a column to be for a derived attribute. example a column monthlysalary and create a column that is a derived attribute - yearly salary. Is this done when creating the table and how is the syntax ?
