title: Importing tab-delimited text file - can't change the column mappings SQL Server 2008
body: <p>I have a very large tab-delimited text file I'm trying to import into SQL Server 2008.  Some of the field names are greater than 50 characters and when I try to change the column mappings using Management Studio, I'm unable to change the data type (default is varchar) or the size (default is 50).  The Edit SQL button is also grayed out.  What gives with this?</p>
  
  <p>I am importing the data through the import wizard in SSMS (right click on database name, tasks, import)</p>
