Answer 1

This will work for your given test data
CREATE TABLE ext_tab (
empno VARCHAR(4),
ename VARCHAR(20),
job1 VARCHAR(20),
deptno VARCHAR(2)
)
ORGANIZATION EXTERNAL (
DEFAULT DIRECTORY import
ACCESS PARAMETERS (
RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY ','
)
LOCATION ('ext.txt')
);
providing that you have set up the import directory correctly.
Tested on 11.2.0.4
As for the reason it was given in the comments above. Always check the .bad and .log files first (created in the directory you put the file in). These are very helpful at telling you why rows are rejected.
I expect you have errors like this in the log:-
KUP-04021: field formatting error for field ENAME
KUP-04026: field too long for datatype
KUP-04101: record 1 rejected in file /import_dir/ext.txt
KUP-04021: field formatting error for field ENAME
KUP-04026: field too long for datatype
KUP-04101: record 3 rejected in file /import_dir/ext.txt
KUP-04021: field formatting error for field ENAME
KUP-04026: field too long for datatype
KUP-04101: record 4 rejected in file /import_dir/ext.txt
and that only WARD was imported because only his name fits into CHAR(4).
