Answer 1

An example of how you can do that :
SQL> create table test_date(a date, b varchar2(30));
Table created.
SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - Production
With the Partitioning, OLAP and Data Mining options
$ cat test_date.dat
20070731,AAA
20070801,BBB
$ cat test_date.ctl
load data
INFILE 'test_date.dat'
REPLACE
INTO TABLE test_date
FIELDS TERMINATED BY ','
a char "TO_DATE(:a,'yyyymmdd') - 1",
b char
$ sqlldr test/test control=test_date.ctl
