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.
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, I apologize if this question has already asked (I already looked in this forum but do not find the answer), I need to have this done as soon as possible. I've following data:
column1 column2 begin_date active ------------- ------------ ---------------- -----------
1253 1057 1/1/2006 0
1253 1057 1/1/2007 0
1253 1057 4/1/2007 0
1253 1057 7/1/2007 1
I need to have the final result as following: (the new end_date column is the value of the begin_date in the next row -1)
column1 column2 begin_date active end_date ------------- ------------ ---------------- -------- ------------------
Can someone help me out in providing the STEPS to solve this problem. My scneario is, I've a table which has got 2 fields and 5 default row values have been filled in. Now, using the above, duirng package runtime, it need to dynamically create additional field and has to store values like for.e.g (0001 America). I'm getting the following error while executing the ssis package.
1. [DTS.Pipeline] Warning: Component "Derived Column" (1170) has been removed from the Data Flow task because its output is not used and its inputs have no side effects. If the component is required, then the HasSideEffects property on at least one of its inputs should be set to true, or its output should be connected to something. 2. [DTS.Pipeline] Warning: Source "OLE DB Source Output" (87) will not be read because none of its data ever becomes visible outside the Data Flow Task.
Please suggest with your valuable solution at the earliest.
CASE WHEN Data IS NULL THEN NULL WHEN SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(CYCLE_YYYYMM AS VARCHAR(9)), 4, 6) IS NULL THEN 0 ELSE RTRIM(SUBSTRING(REPLICATE('0', 9 - LEN(Data)) + CAST(Data AS VARCHAR(9)), 4, 6)) END
From what I have seen the first option is not really required
I am trying to upload a csv file into a destination SQL Server table using Data FLow objects in MS SQL Server 2005 SSIS. My destination table X has a date column while my source data file (for which i have a flat file connection) does not have a date column. I created a Derived column for date using the system date function in my Source data object and ran the package but it returned errors. I changed the data type of the derived column but I still get errors.
is there any other way i can get the date on the fly i.e generate a date for the incoming source file and map that (insert into) to the destination table ?
i 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

I have flat file source from which data is imported to a Sql table.The target column is int and input column is string .The column has some numeric values and some blank values.when I tried to convert into int values it fails.
I am Using Derived column between Source and Destination Control. the Source input column PriceTime is String Data type. but in the Destination is should be a DATE TIME column. How to Convert this string to DateTime in the Derivied Column Control.
I already tried to in the Derived column control
PRICEDATETIME <add as new column> ((DT_DBTIMESTAMP)priceDateTime) database timestamp [DT_DBTIMESTAMP]
But still throwing Error showing type case probelm
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.
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:
' 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.
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.
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,
Hi, 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?
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?
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:
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.
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 -
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'.".
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 ?
but while transfering record from text file to table i need some logic here
my text file is "ID"|"Name" 1012|"10AA" 1013|"10BB"
logic is 10 should be replace by variable VID = 98
I defined this veriable as int
My ID column in database is int and Name column is varchar(50)
I try here expression like ID != 98 ? @[User::VID] : ID it work fine
but for varchar column I am not able to do I got error when i write expression SUBSTRING(Name,1,2) != "98" ? [DT_STR, 50, 1252] "(@[User::VID])" + rest of value of column : [Name]
my final output in table should be like ID..Name 98..98AA 98..98BB
I would like to validate datatype using Derived Column.My data type are such as numeric(X,X),datetime,int, and varchar.How do I do this using Derived Column.Example if row does not qualify as ISNUMERIC()...throw it in ERROR table else send it to SUCCESS table.Any Idea ?
Hi,I have a view that looks something like this -CREATE VIEW myview AS SELECTmyudf(col1) as col1, col2, col3FROM mytableThe view has an 'INSTEAD OF' trigger on it to do the correct thing oninsert. 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!
