详细讲解Oracle SQL*Loader的使用方法(3)

( rec_no "my_db_sequence.nextval",

region CONSTANT 31,

time_loaded "to_char(SYSDATE, HH24:MI)",

data1 POSITION(1:5) ":data1/100",

data2 POSITION(6:15) "upper(:data2)",

data3 POSITION(16:22)"to_date(:data3, YYMMDD)"

)

BEGINDATA

11111AAAAAAAAAA991201

22222BBBBBBBBBB990112

LOAD DATA

INFILE mail_orders.txt

BADFILE bad_orders.txt

APPEND

INTO TABLE mailing_list

FIELDS TERMINATED BY ","

( addr,

city,

state,

zipcode,

mailing_addr "decode(:mailing_addr, null, :addr, :mailing_addr)",

mailing_city "decode(:mailing_city, null, :city, :mailing_city)",

mailing_state

)

将数据导入多个表：

如:

LOAD DATA

INFILE *

REPLACE

INTO TABLE emp

WHEN empno !=

( empno POSITION(1:4) INTEGER EXTERNAL,

ename POSITION(6:15) CHAR,

deptno POSITION(17:18) CHAR,

mgr POSITION(20:23) INTEGER EXTERNAL

)

INTO TABLE proj

WHEN projno !=

( projno POSITION(25:27) INTEGER EXTERNAL,

empno POSITION(1:4) INTEGER EXTERNAL

)

导入选定的记录：

如下例： (01) 代表第一个字符, (30:37) 代表30到37之间的字符:

LOAD DATA

INFIL
