I'm trying to Load Data into a Teradata table using Fastload in Teradata Studio on a Mac. The table deliberately has all columns defined as VARCHAR since some of the fields have leading zeroes that I would like to retain. Sample record looks like this: 01,1,14,149,08,S7,6324. Fastload fails saying "Cause = java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String;". Fastload for the same table and input file worked previously when I had most of the data types set as INTEGER. But the leading zeroes were not being retained. How do I get around this problem? Do I have to use a script?
