Null values are being inserted into Primary key column when loading data via Sql*loader in Direct Path Load mode.
--Steps to reproduce:
a) Create a table say emp in a schema
create table emp
(accno number primary key);
b) Create a sequence in the same schema
create sequence emp_seq;
c) Create a control file - load.ctl with contents as:
INTO TABLE emp
WHEN (1:2) = 'KB'
into table emp
WHEN (1:2) = 'BB'
d) Create a datafile called loaddata.dat with contents in the same directory
e) Use the following command
sqlldr <username>/<password> control=load.ctl log=load.log direct=yes
You would find that first command puts a null value into the table where as the column is defined as primary key.
