I have a flat file and one of the column in the flat file has composite characters and In the Flat File connection manager I defined that particular column as
DataType - DT_WSTR
OutputColumnWidth - 40
The actual column length in text file is 30 but as this has composite keys I increased it to 40. Now I placed a Dataviewer after the Flat File Source to see how the data is passed and I see different values For example Société is passed as Société
Kindly help me to prevent this character conversion.
Please let me know if you need additional details. Thanks in advance
I changed the code page on the Flat File connection manager to UTF-8 and it solved the issue :).

When using a copy activity in Azure Data Factory to copy a typical CSV file with a header row into Parquet sink, the SINK fails with the following error due to the column names in the CSV having spaces in the header.
The column name is invalid. Column name cannot contain these
character:[,;{}()\n\t=]
The CSV is pipe delimited and displays just fine using the preview feature of the dataset with the first row marked as the header. I see no options to handle this use-case on the parquet side (sink) of the copy activity. I realize this can probably be addressed using a data flow to transform column names to remove spaces, but does that mean the native copy activity is incapable of handling this condition where a space in included in a header row?
EDIT: I should have added that dataset uses default mappings so that we can use the same dataset for any CSV to PARQUET copy. The answer provided will work for explicit mappings, but we don't see any resolution for folks who use default/dynamic mappings since we do not have access to the column names to remove spaces.
As we can note from the official Doc here
Error code: ParquetInvalidColumnName
Message: The column name is invalid. Column name cannot contain these character:[,;{}()\n\t=]
Cause: The column name contains invalid characters.
Resolution: Add or modify the column mapping to make the sink column name valid.
If you would like continue to use copy activity, there are few workarounds
1. make sure you have selected Column delimiter as Pipe(|)
2. If feasible, in mapping settings > import schema and rename the column name without spaces in destination column.
This is still an ongoing issue or request, follow here for more.
I have a flat file with the below value:
AI9983|01|20170802|119965.57|0.000000|0.000000|||
AI9983|01|20170803|119713.62|-0.210019|-0.210019|||
I read the file, the value 119965.57 gets stored as 119965.60
the value 119713.62 gets stored as 119713.60.
When reading the flat-file the variable is set as float[DT_R4]
It gets stored in the database as decimal(28,2).
Can someone help me to sort this out, I need to store the value as it is in the flat file into the database.
I am not using any derived column or transformation here.
Float will not return a reliable result, so it is challenging to use in database work.
In the flat file connection manager, go to the columns tab, select the column and change the data type to numeric with a DataPrecision of 28 and Scale of 6 (Based on the sample data provided in the question).
Hi all quick question for you.
I have an SSIS2012 package that is reading a flat file (.csv) and is loading it into a SQL Server database table. However, I am getting an error for one of the columns when loading the OLEDB Destination:
[Flat File Source [32]] Error: Data conversion failed. The data conversion for column "Active_Flag" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
I am wondering if this is because in the flat file (which is comma delimited), the values are literally spelled out "TRUE" or "FALSE". The advanced page on the flat file properties has it set to "DT_BOOL" which I thought was right. It was on DT_STRING originally, and that wasn't working either.
In the SQL server table the column is set up as a bit, and allows nulls. Is this because it is literally typed out TRUE/FALSE? What's the easiest way to fix this?
Thanks for any advice!
It actually turned out there was a blank space in front of "True"/"False" in the file. Was just bad data and I missed it. Fixing that solved my issue. Thank you though, I did try that and when that didn't work that's when I knew it was something else.
I need to export varbinary data to file. But, when I do it using Column Transformations in SSIS, the exported files are corrupt. There are few junk characters at the start of the file. On removing them, the file opens fine.
A similar post for BCP, says that these characters specify the data length.
Would like to know how to address this issue in SSIS?
Thanks
Export transformation is used for converting the varbinary to files.I have tried something similar using Adventure works which has image type of var-binary data.
Following Query is used for the Source query. I have Modified the query
since it does not have the full path to write image files.
SELECT [ProductPhotoID]
,[ThumbNailPhoto]
,'D:\SSISTesting\ThumnailPhotos\'+[ThumbnailPhotoFileName]
,[LargePhoto]
,'D:\SSISTesting\LargePhotos\'+[LargePhotoFileName]
,[ModifiedDate]
FROM [Production].[ProductPhoto]
Used the Export column transformation[also available in 2005 and
2008] and configured as follows.
Mapped rest of the columns to the destination.
After running package all the image files are written into the
respective folders[D:\SSISTesting\ThumnailPhotos\ and D:\SSISTesting\LargePhotos].
Hope this helps!
We have an SSIS package which reads from a DB, creates a flat file from that info, and drops it to a file server.
I recently made an update to the package's query which is used against the DB, adjusted the column mappings, and placed it under the SQL Job which ran the SSIS package before.
The problem is that the text qualifier in the flat file should be a quotation mark: ". But when I checked the flat file it produced, the text qualifier showing is: _x0022_
I investigated the Text Qualifier property for the DestinationConnectionFlatFile, and it is set to a quotation mark: "
How can I ensure the flat file will have a text qualifier of quotation mark?
Here is a previous answer I found when this happened to me:
SSIS exporting data to flat file renders double quotes as hexadecimal characters
Additionally ,
This issue occures because of installation issue. So if you see this sort of Issue, It mean if you are loading from file Database table and file contains 100 records , then instead of 100 records only 99 records would get loaded to database , last records would get skipped.
I had same issue, to fix that I had re-instalation of
1) MS Visual Studio
2) MS BI Studio
in the sequence mentioned above.
Given below are the two solutions :
Solution 1: Open the Package in Notepad and Edit the Value present in the "TextQualifier" of particular object to """.
object Name
"
Solution 2: open the Package and Replace the Value in the "TextQualifier" of the Flat File Connection Managers (FFD,SRC,SOURCE) to "\"".
Solution 1: Open the Package in Notepad and Edit the Value present in the "TextQualifier" of particular object to (") " follow semicolon
object Name
"
