I am using ssis 2008 and trying to extract data from a tab delimited file
In the file above, I am getting an error where Counter=1494059
I am using a derived column transformation and it has a formula '(DT_DBTIMESTAMP)Date'
Due to that I am getting following errors:
[Derived Column 1 [295]] Error: An error occurred while attempting to perform a type cast.
[Derived Column 1 [295]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Derived Column 1" (295)" failed because error code 0xC0049064 occurred, and the error row disposition on "input column "Date" (297)" 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.
I tried to redirect erranous rows..but it is also not working
Can anyone pls help to sort this one out..
p.s. all the previous files were processed successfully, we are getting errors with this one file only..though it has identical structure and encoding

Rather than looking at the source data in Excel, can you please open it in Notepad++ or similar and then have a close look at the offending data?

From your screen shot, everything looks fine. But Excel has a tendency to mask problems.

If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

Now instead of Date and time conversion..I tried following:

SUBSTRING(LTRIM(RTRIM([Date])),LEN(LTRIM(RTRIM([Date]))) - 3,LEN(LTRIM(RTRIM([Date])))) + "-" + SUBSTRING(LTRIM(RTRIM([Date])),1,FINDSTRING(LTRIM(RTRIM([Date])),"/",1) - 1) + "-" + SUBSTRING(LTRIM(RTRIM([Date])),FINDSTRING(LTRIM(RTRIM([Date])),"/",1) + 1,2)+" 00:00:00.000"

STILL NOT WORKING 🙁

I get the error 'An error occurred while evaluating the function. '

How are you so sure it fails on that specific line?

I checked it in the Data Viewer

I thought you said redirecting error rows didn't work?

Yes, so there are no rows getting redirected on error output i.e. RED pipeline..and also the data viewer on Green pipeline is telling me where the error is

And why is that, if I may ask?

Data viewer on the Green pipeline is showing me all the records before that particular erroneous record

Sure? It might also show all the records loaded into the first buffer loaded when the error occurs.

SSIS doesn't load data row by row.

ok..I tried almost everything..but the derived columns seems to be giving problem..so I have resorted to this:

I am creating a temp table..dumping the flat file as it is into it..and then using CONVERT in execute_sql task..I move the records over to the final destination table..

I agree that it is one more extra step and will take some extra time..but it is getting the job done for now
