I am trying to replace the value of a column in a derived column component, but it will not let me change the datatype.
It has decided that the column is a float, which is wrong.
How can I change it to the correct type?
Hi,
I have a data flow task where I have mutiple columns (of different data types) , I want to create a single column using all these columns in XML format and load it into a table with a column of datatype XML. Can I accomplish this using Derived column tranformation?
Thanks
Here is my expression in a derived component:
"Failed insert into PONL_WELL. WELL_NO=" + (DT_WSTR,10)PROP_NO
PROP_NO comes from ms sql server , and the derived component datatype for this column is DT_WSTR.
The destination will be ms sql server, and i have a data conversion after the derived component to cast from DT_WSTR to DT_STR.
However, the derived component failed everytime giving me
Error: 0xC0049064 at Load Ponl_Well, Derived Column [1342]: An error occurred while attempting to perform a type cast.
Anyone know how i can eliminate the data conversion component and just do my string and column concatenation in the derived column and have it output as DT_STR?
Hi, friend,
l've 2 variables A & B from source database which i used to calculate C with the following formula, i.e.
C = 100 * A/B
In case of B = 0 (DIV BY ZERO), C should be equal to -9999.
l've set the datatype for A & B are INT, C is FLOAT at targetting database.
So l used to derived column to calculate C as,
B == 0 ? -9999 : 100 * A/B
After l run the package, l realize that all my C is INTEGER rather than FLOAT.....it seems that SQL server has evaluate the wrong datatype for me....anyway to overcome this?
I am trying to change the value from "T" to "A" in trans_type column based on the value in Transfer_of_Provider column..
I like to change "T" to "A" if the value of Transfer_of_provider column is "Y".
"Transfer_of_provider" coulmn has NULL value..
I've used the below logic to do that... but becuase of NULL value in "Transfer_of_provider" column .. it keep giving me a truncation error..
TRans_type = (ISNULL(Transfer_Of_Provider) ? "N" : Transfer_Of_Provider) == "Y" ? "'T" : "A"
How can I make this work?
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,

Hello,How do I change the datatype of a column in a CSV file. Preferably in the select statement (apparently Cast, Convert, & Replace functions don't work when selecting from a CSV). I have a page where users upload their CSV files to and then I use SQLBulkCopy to insert all the records into my sql table. The problem is with columns of money data. EX: "$2,000" >> 2000The CSV file interprets the "$2,000" as a string of text. How do I convert it to a decimal so I can insert it into my sql database?

View 4 Replies View RelatedHi,
I have just started learning SSIS. I have created a new package which is as follows :
SOURCE QUERY ----> Derived Column ------> Destination Customer Info
Source Fields are
FirstName
LastName
OrgCode
Phone
Ref1
The Derived column is adding a new Column name FullName and the friendly expression for it is FirstName + "Null" + LastName
Destination has all the columns are same as source columns with similar datatypes.
When i start the debugging process i get the following error:

Hi all€”Given a date field called [Reading Date] and a time field called [Reading Time], I am attempting to use the following transformation on the field to test for nulls and combine the data into a single field called [Reading Date/Time]:
(DT_WSTR)([Reading Date]== "") || ISNULL([Reading Date]) || (DT_WSTR)([Reading Time]== "") || ISNULL([Reading Time])? (DT_DBDATE)GETDATE() : (DT_DATE)(SUBSTRING((DT_WSTR,8)[Reading Date],5,2) + "/" + SUBSTRING((DT_WSTR,8)[Reading Date],7,2) + "/" + SUBSTRING((DT_WSTR,8)[Reading Date],1,4) + " " + SUBSTRING((DT_WSTR,8)[Reading Date],1,8))
I get the following error:
Error at Data Flow Task [Derived Column1[177]]: Attempt to parse the expression "(DT_WSTR)([Reading Date]== "") || ISNULL([Reading Date]) || (DT_WSTR)([Reading Time]== "") || ISNULL([Reading Time])?

The expression might contain an invalid token, an incomplete token, or an invalid element. It might not be well-formed or might be missing part of a required element such as a parenthesis.
Here is a sample [Reading Date]:

I have a data source that I access via odbc in a DataReader Source component in SSIS. I can access the data fine. However, I am having problems with certain fields that are numeric (specifically home prices ranging from 100,000.00 to 99,999,999.00). In the advanced editor for my data reader source under the input and output properties tab, in data reader output under the external columns and output columns, these fields for some reason default to numeric data types with a precision of 4 and a scale of zero, not large enough to hold the data that is coming in. This causes errors that make the data come in as null (after i specify to ignore the errors).
I can change the precision and scale to 18 and 4 in the external columns, but when I try to change the datatype, precision or scale in the output columns I get the following message:
Property Value is not valid.
The details are:
Error at Import DataReader Source: The data type of output columns on the component "DataReader Source" cannot be changed.
Error at DataReader Source: System.Runtime.InteropServices.COMException (0xC020837D)
at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)

I 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.
Hi,
I have created a program that imports a csv into the sql server. but during that import I need to track all the errors that occured for some malformed rows. I think I need to use the error output collection of the dataflow components to track the errors. I figured out that every dataflow component has a error output collection along with the data output collection. I want to write those error outputs into a separete database. So, I have created a SQL server data destination component and created a path between derived columns error output and it input collection. But it is not working as expected. can any body help on this?
or can anyone give me any example how to use/handle error output collection in SSIS?
I will appreciate all kind of suggestions.
thanks

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!

Hello all,First of all, I must state that I'm new to SQL Server, but have been along-time software guy for quite some time. Please excuse the potentialsimplicity of the solution to my problem.I create a blank database (TestDB) under my server machine (SQL Server 2000Standard)... I then create a new table (Run_Number) with only one record init.Field(1): Next_Run_Number (bigint), identity w/ seed 1 and increment 1, nonulls, PKI can successfully save this new table to disk and everything seems fine...problem comes up when I go back into the table and change the datatype from(bigint) to (int). I try and save changes and I get the following errorprompt:'Run_Number' table- Unable to create index 'PK_Run_Number'.ODBC error: [Microsoft][ODBC SQL Server Driver]Invalid cursor stateI've checked and there's plenty of disk space available and the dbase is setto grow by 10% as necessary. Any ideas what could be going wrong? I'm ableto successfully make this change on my other machine running SQL Server 2000Personal. Thoughts?TIA!-J.C..

Table structure as follows

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
I am running Microsoft SQL Server 2012.
I had created a database named "Company-Data" that contains a table named "tblStock". This table contains several columns such as ID, Product, Quantity. The datatype for the column "Quantity" is INT.
I had entered 100 records to the table, now I want to change the datatype for the column "Quantity" from INT to MONEY.
How can we do this without loosing the data that has been entered the the column previously.
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.

Beli

Hello,
I would like to change the datatype on a particular column from varchar to bigint across 100's of tables within a database.
I have the command ready which is:
ALTER TABLE tablename ALTER COLUMN columnname BIGINT
The problem happening is that it seems there are constraints across all the columns in every tables.
The error message is:
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF__tablename__columnname__0ABD916C' is dependent on column 'columnname'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN columnname failed because one or more objects access this column.
I understand that if I delete this constraint, then it will let me modify the datatype of the column, but since there are tons of them and they are randomly named, how do I achive changing the datatype across multiple tables in bulk.
What would be the best process to change the datatype of ntext fields.
I assume just changing the datatype - is not the way to go?
