Integration Services :: Column Names Using Lineage ID
Nov 17, 2015
I am working on a custom component to implement some rules based on the column name. I am looking for ways to identify the column name using lineage id. Is there anyway we can derive column name using the lineage id?
We run std 2008 r2. I'm looking at the files this transform is complaining about. They seem to be named appropriately. The customerid folders don't exist when this runs. I'm going to put one in place to see if that is the problem.
The errors i'm getting are...
[Export Column ] Error: The file name "c:usersmyuserid heprojectnamecustomeridafilename.doc" is not valid. The file name is a device or contains invalid characters. [Export Column ] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Export Column" (22)" failed because error code 0xC020207F occurred,
and the error row disposition on "input column "FILENAME" (29)" specifies failure on error. An error occurred on the specified object of the specified component.
There may be error messages posted before this with more information about the failure.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Export Column" (22) failed with error code 0xC0209029
while processing input "Export Column Input" (23). 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. There may be error messages posted before this with more information about the failure.
As part if a recent requirement I have to export Chinese/Singaporean names in a CSV file. The data in the tables is a NVARCHAR(256).
I am using a FlatFile Connection manager where all the present columns from the table are exported as NVARCHARs. My understanding was that the Chinese/Singaporean names would blend seamlessly with NVARCHARs in place. But, they get garbled when pushed to the CSV.
Here is the connection manager setup
There are a lot of suggestions of fixing this by copying/pasting to a notepad file and changing the formatting... But I cant do that since the file is generated using a schedules SSIS package. How can I tweak the process to fix the issue?
is there any "robust" way to find out the name of a field in the pipeline by it's Lineage ID programatically? There is a sample code out there (on one of the blogs) but it seams not to be reliable...
The usecase is easy... What is the field name in an error output of that column that causes the error? We don't want to have hardcoded LineageIDs in the error handling so I think it's the best idea to go with field names... However we only get that LineageID...
I have a situation where I want to load the Excel file dynamically, and the excel file have different columns or even worksheet name. How I could approach this? I believe there's no way to modify the meta data (specifically the mapping) in the data flow.
I have an excel file which contains lots of sheets. Some of them are named as DW-<day>-<month> (for e.g; DW-1-July). Like this I have sheets for the whole month. I have other sheets too with a different name. I would like to import data from these sheets only (DW ones). Upon my research I have found that this can be achieved via For Each Loop Container (I guess!).
Post data import, I have a set of T-SQL query that I plan to execute via Execute SQL Task.
I need to move specific files from a server to another server on a monthly basis. There are hundreds of files that are in the source directory and I need to move approximately 40 of those to the destination server. I would like to easily add or delete the file list as needed. I have seen where several variables were created for for each file name (and one for the path) and the ForEach Loop would go through them. With 40 or more I was thinking that I could make a connection to an Excel spreadsheet or text file with a record for each file name and read in and and move to the next record and make that value become the content of a "FileName" variable. Then if I wanted to add another file name I could just add another record to spreadsheet/text file or remove and the package would handle automatically....
I have successfully created a linked server between SQL Server 2008 R2 and a Postgres db, and all is working fine, except when I try to run a stored procedure that returns a TEXT column.The top lines of the stored procedure (function in postgres) that is called are:
CREATE OR REPLACE FUNCTION get_defects() RETURNS TABLE(defectid bigint, featurevalues text) AS ...
The function obviously executes correctly in postgres, however when I try to execute the function in SQL Server via the linked server:
SELECT * FROM OPENQUERY(POSTGRES, 'SELECT * FROM get_defects()') I get the error:
OLE DB provider "MSDASQL" for linked server "POSTGRES" returned message "Requested conversion is not supported.". Msg 7341, Level 16, State 2, Line 1
Cannot get the current row value of column "[MSDASQL].featurevalues" from OLE DB provider "MSDASQL" for linked server "POSTGRES".The problem seems to be when trying to return the TEXT column featurevalues, as the following query executes as expected:
SELECT defectid FROM OPENQUERY(POSTGRES, 'SELECT * FROM get_defects()')
I am having one store procedure which use to load data from flat file to staging table dynamically.everything is working fine. staging_temp table have single column.all the data stored in that single column below is the sample row.
after the staging_temp data gets inserted into main table.my probelm is to handle such a file where number of columns are more than the actual table.if you see the sample rows there are 4 column separated by "¯".but actual I am having only 3 columns in my main table.so how can I get only first 3 column from the satging_temp table.output should be like below.
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
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.
I am working on 1 POC project.I have 2 customer having source file in txt format, but the column sequence of both customer are diffrent.Number of columns in all files are like below.
ID NAME AGE 1 VIPIN 29
ID AGE NAME 2 29 jayesh
As per source file you can see that CustA have column sequence ID,NAME,AGE and CustB Have ID,AGE,NAME sequence .I have target table #Temp with ID,NAME,AGE sequence.Like that I have many files from both customer, I have to load in ID,NAME,AGE sequence from all source file to target table.How can we change the sequence of source column before loading to target table.
I have 10 columns i.e from Segment1 to Segment10. I need to concatenate it with ".". All 10 segments can be null. If any of the segment is null i do not want to show ".". This is the expression I am using
I can preview the SQL command in the OLE DB Source Editor and bring back all columns and results just fine but when I click on the Columns I get
TITLE: Microsoft Visual Studio ------------------------------ The component reported the following warnings: Error at Data Flow Task [OLE DB Source ]: No column information was returned by the SQL command.
The columns are there in the preview - why can't SSIS get the column information?
I'm trying to write a conditional split where I want to bring in only records where the date is less than today, but my problem is that I can't simply do this Column < GetDate() because if something comes in today, it takes the time into account and it will bring that record for today. You can do this in SQL, but I'm not sure how to do that in SSIS
I receive a data feed from a third party in a pipe delimited file. From time to time, they add a column at the end. I would like my ssis package to continue to process the data even if they add a column with out it breaking. How best do I handle this situation?
I have an SSIS package in which I need to include a derived column. I've done derived columns a ton when there is just one condition being "tested". In this case there are two. I have the following update statement for a table I'm inserting data into:
UPDATE STAGING_DIM_AR_INVOICE SET SC_CODE = ( CASE WHEN REC_TYPE = 'P' AND SC_CODE IS NULL THEN 'ag' WHEN REC_TYPE = 'I' AND SC_CODE IS NULL THEN 'OL'
I'd like to be able to address this case on the load itself. I've used CONDITIONAL before, but not sure how that would work in this case. I'm trying to keep it as "simple" as possible.
My Requirement IS : 1<sup>st</sup>run: if the record does not exist in the table insert the record (file_name, last_modified_file_date) and create a copy in the archive folder with file_name_currentdate.csv
Daily run: retrieve the last_modified_file_date from the input file and check if the retrieved date is greater than the last_modified_file_date in the table:
If true: create a copy of the input file in the archive folder and update the last_modified_file_date in the table with the retrieved date
If false don’t do nothing because the file has been archived in one of the previous runs.I have already retrieving the modified date and File Nae iserting into Filename Table: (That table has 2 columns which are FileName and FileDate) so In script task everytime the variable getting Modified date(retrieve the last_modified_file_date from the input file). How I can Compre the existing table record and variable. I have already imported the all Filenames and Modified into table like below.
