SQLLoader3(数据文件没有分隔符时的导入)

数据文件：D:\oracletest\ldr_tab_fiile.dat
1、数据文件字段中间以制表符TAB隔开：
7369 SMITH CLERK
7499 ALLEN SALESMAN
7521 WARD SALESMAN
7566 JONE SMANAGER
===控件文件：

LOAD DATA
INFILE 'D:\oracletest\ldr_tab_fiile.dat'
REPLACE
INTO TABLE EMP2
FIELDS TERMINATED BY x'09'  --以制表符tab分隔
(EMPNO,ENAME,JOB)

===查询结果，导入成功

SQL> select * from emp2;

EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- -------------- ---------- ---------- ----------
7369 SMITH CLERK
7499 ALLEN SALESMAN

控制文件：

LOAD DATA
INFILE 'D:\oracletest\ldr_tab_fiile.dat'
REPLACE
INTO TABLE EMP2
(
EMPNO position(1:4),
ENAME position(*+1:14), --*表示从上一字段结尾
JOB position(*:25)
)
