Issue importing large file into SQL server I am trying to import a 4gb csv file into a new table in sql server using the wizard. And when I do I get the errors below. I also included the 2nd row of the file I am trying to import without the headers. Any idea on how I can fix this?

You're getting a truncation error, meaning the data that's coming in is larger than the field size you have specified.  Try increasing the destination table field size and you should be good to go.

I get these alot when I work with email addresses as the SQL import wizard defaults to 50, I always have to increase it every time I do a fresh import.
