Simple contrived test case.
Given the following data files
y:\stagingArea\db\vertica\t1.csv "1" y:\stagingArea\db\vertica\t2.csv "1.0" y:\stagingArea\db\vertica\t3.csv 1 C:\Development\YADAMU>

select version();
--
drop schema "test";
--
drop table "reject_t1";
--
drop table "reject_t2";
--
drop table "reject_t3";
--
create schema "test";
--
