As a slight alternative to  FazianMubasher s answer  instead of allowing NULL for the specified column  which may for many reasons not be possible   you could also add a Conditional Split Task to branch NULL values to an error file  or just to ignore them

It usually happens when Allow Nulls option is unchecked   Solution    Look at the name of the column for this error warning  Go to SSMS and find the table Allow Null for that Column  Save the table Rerun the SSIS   Try these steps  It worked for me   See this link

It s as the error message says  The value violated the integrity constraints for the column  for column  Copy of F2   Make it so it doesn t violate the value in the target table  What the allowable values are  data types  etc are not provided in your question so we cannot be more specific in answering   To address the downvote  No  really it s as it says  you are putting something into a column that is not allowed  It could be Faizan points out  that you re putting a NULL into a NOT NULLable column  but it could be a whole host of other things and as the original poster never provided any update  we re left to guess  Was there a foreign key constraint that the insert violated  Maybe there s a check constraint that got blown  Maybe the source column in Excel has a valid date value for Excel that is not valid for the target column s date time data type    Thus  baring concrete information  the best possible answer is  don t do the thing that breaks it  In this case  something about  Copy of F2  is bad for the target column  Give us table definitions  supplied values  etc  then you can specific answers   Telling people to make a NOT NULLable column into a NULLable one might be the right answer  It might also be the most horrific answer known to mankind  If an existing process expects there to always be a value in column  Copy of F2  changing the constraint to NULL can wreak havoc on existing queries  For example  SELECT   FROM ArbitraryTable AS T WHERE T  Copy of F2          Currently  that query retrieves everything that was freshly imported because Copy of F2 is a poorly named status indicator  That data needs to get fed into the next system so    bills can get paid  As soon as you make it such that unprocessed rows can have a NULL value  the above query no longer satisfies that  Bills don t get paid  collections repos your building and now you re out of a job  all because you didn t do impact analysis  etc  etc

Teradata table or view stores NULL as     and SQL considers it as a character or string  This is the main reason for the error  The value violated the integrity constraints for the column   when data is ported from Teradata source to SQL destination   Solution 1  Allow the destination table to hold NULL Solution 2  Convert the     character to be stored as some value in the destination table

I ve found that this can happen due to a number of various reasons   In my case when I scroll to the end of the SQL import  Report   under the  Post-execute  Success   heading it will tell me how many rows were copied and it s usually the next row in sheet which has the issue  Also you can tell which column by the import messages  in your case it was  Copy of F2   so you can generally find out which was the offending cell in Excel   I ve seen this happen for very silly reasons such as the date format in Excel being different than previous rows  For example cell A2 being  05 02 2017  while A3 being  5 2 2017  or even  05-02-2017   It seems the import wants things to be perfectly consistent   It even happens if the Excel formats are different so if B2 is  512  but an Excel  Number  format and B3 is  512  but an Excel  Text  format then the Cell will cause an error   I ve also had situations where I literally had to delete all the  empty  rows below my data rows in the Excel sheet  Sometimes they appear empty but Excel considers them having  blank  data or something like that so the import tries to import them as well  This usually happens if you ve had previous data in your Excel sheet which you ve cleared but haven t properly deleted the rows   And then there s the obvious reasons of trying to import text value into an integer column or insert a NULL into a NOT NULL column as mentioned by the others

Delete empty rows from Excel after your last row of data   Some times empty rows in Excel are still considered as data  therefore trying to import them in a table with one or more non nullable columns violates the constrains of the column   Solution  select all of the empty rows on your sheet  even those after your last row of data  and click delete rows   Obviously  if some of your data really does vioalte any of your table s constraints  then just fix your data to match the rules of your database
