In SSIS, I'm starting with a SQL Source (a table). It has 3 columns, including a varbinary column ("FileBlob") that comes from a filestream (this shows up as type DT_IMAGE in SSIS).
In the first data flow component, I convert the varbinary column to DT_TEXT, and output the result to a flat file. This works.
In the next step, I read in the flat file I just created, attempting to convert the DT_TEXT column back to DT_IMAGE.
I get this error:
The conversion returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.
I'm assuming there's a way to do a round-trip conversion of the binary data to text, and then back to binary. Just not sure what I'm missing. Thanks.

I've created a table in SQL Server 2016 with this definition:
CREATE TABLE Stage.Test (f1 DATE NULL);
INSERT INTO Stage.Test (f1) VALUES ('1/1/2000');
Notice the f1 column uses the DATE data type.
Then I created a data flow task in SQL Server Data Tools (VS 2019) to load data from that table. I created an OLEDB Source Component and set the source table to Stage.Test. But when I examine the data type of the "f1" column (in both the 'External Column' and 'Output Column' columns), it says it's a Unicode string:
Why is it choosing a Unicode string instead of DT_DATE?
I haven't seen this exact example when it comes to date fields but SSIS converts data automatically when it has detected the field to be of a certain type. Perhaps it's the '/' in your date field that does it. We do not use this date format over in these parts of the world so I've never had the problem. You can especially see this when you import excel files with SSIS. I usually have this problem with strings where unicode strings can sometimes become non-unicode strings.
A way to fix could be to:
edit the sql query to explicitly cast the field as date
add a conversion step in the data flow after the source (like a derived column getting the parts of the string in the right order)
try to change the output datatype by right clicking on the source in the data flow and using the advanced editor and then edit the output column datatype:
SSIS Source Advanced Editor Output
I'm not sure if that 3 would work with this date format issue as I do not have experience with the format myself but it is working fine for my unicode/non-unicode problem.
I have a CSV file that I exported myself out of SFDC. It has about 60k records. 3 columns are numbers, 1 is a date, & the other dozen or so are Text.
In SSMS or SSIS, when I attempt to import the file to a table - the importer errors out on the same row of data each time "15421" with the error message:
The data conversion for column XXXX returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page."
The error is pointing to one of the Text columns. When I look at the data in the table to see what imported, the data ends exactly that that row and column - the column is empty. The contents of the column is 2 characters.
My first attempt was to use DT_STR (255), resulting in the error. If I switch to as DT_WSTR (1024) or even DT_NTEXT - the job runs and reports success, but it ends exactly that row and doesn't import the rest of the 45k records - as if something in that row (and in that column?) is indicating the file is finished at that point.
I looked at that file with Notepad ++ and Sublime Text Gremlins, and Sublime Text Hex editor - I can't see anything abnormal in the data or the text qualifying quotation marks, or the comma delimiters... Thoughts? TIA!
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).
I have ODBC DB2 query to get data from database and data type of column only contain varchar(x), date, and int.
However, I'd like to keep them in flat file destination, but isn't able to use UTF-8 encoding. SSIS keeps informing error message below:
[Flat File Destination si_ce_f_hotel_capacity_snapshot_weekly [2]]
Error: Data conversion failed. The data conversion for column
"SOURCE_MARKET_CODE" returned status value 2 and status text "The
value could not be converted because of a potential loss of data.".
This column has varchar(2) datatype from source. And I specify this datatype in ssis flat file structure as DT_WSTR (2).
However, when I change file format to Unicode, everything works just fine.
How do I get this work in UTF-8 ??
Thanks a lot for your answer.
varchar -> DT_STR
Nvarchar -> DT_WST
You should specify the datatype in ssis flat file structure as DT_STR or use the ssis data conversion transformation tool
You need to do a data convertion in the middle of your data flow. This can be done by using a Derived Column or Data Convertion Data Flow Transformation.
I am getting this error when trying to execute the SSIS package.
[Flat File Destination [22]] Error: Data conversion failed. The data
conversion for column "DC" returned status value 4 and status text
"Text was truncated or one or more characters had no match in the
target code page.".
The column is of size 10 and I want that to be 4 in output, I had that set in my flat file but is not working.
Please advise where I am going wrong.

If you don't want to mess with the Flat File properties, you could trim the value in your data source. IE SELECT SUBSTRING(Column,1,4) AS Column FROM Table.
SSIS Error: Data conversion failed. The data conversion for column “”RECIPIENT”” returned status value 4 and status text “Text was truncated or one or more characters had no match in the target code page.
Answer:-
(1) Just Right Click on Connection string for your Flat file source and got advanced column and find "RECIPIENT" Column properties update Column size with actual size like from 50 to 100.
(2) Right Click on Flat File Source and choose “Show Advanced Editor”
Go to “Input and Output Properties “ Tab
Expand “Flat File Source Output” and choose “External Columns”
(3) Select column that is causing this error (In my case column is “RECIPIENT” as per above error message) and on right hand side, increase length say 100 or 200 or depending on your column length
(4) Now select “Output Columns” and select same column as above and make this value same as we did in Step 4, in my case its 200 as shown below.
(5) Run It works.
