Steph,

'3236' is a string not a numeric. As I see it (novice that I am) you have
three choices. 1) Write an external program (gawk, sed, etc.) to remove the
quotes around that field. 2) Import the data into an intermediate table and
then using an after trigger move and manipulate the data using CAST. 3)
Import the data into your table using a BEFORE trigger and manipulate the data
using CAST.
