the problem here is that "" is not an integer. 

0 is.  If you were to write a simple script file to process the input file 
and turn the empty fields into 0s where they should be because they're 
integers you're set.

OR, you can build a temp table with all text columns, import into that, 
then use a select query to change the blank text columns to the character 
0, then import that into the target table.
