实例解析：sqlldr加载数据到不同表的问题
◆首先我们来创建测试表：
D:\Orion>sqlplus eygle/eygle
SQL*Plus: Release 9.2.0.6.0 - Production on 星期一 11月 11 12::20 2007
Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
连接到:
Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.6.0 - Production
19:53:59 SQL> create table test1 (
19:54:14 2 a1 varchar2(10),
19:54:21 3 a2 varchar2(10),
19:54:26 4 a3 varchar2(10));
表已创建。
已用时间: 00: 00: 00.03
19:54:32 SQL> create table test2 (
19:54:35 2 a1 varchar2(10),
19:54:39 3 a2 varchar2(10),
19:54:40 4 a3 varchar2(10));
表已创建。
已用时间: 00: 00: 00.04
23:21:42 SQL> exit
从Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production

◆然后我们来测试数据:
D:\Orion>cat data.txt
01,KunMing,YunNan
02,BeiJing,BeiJing
02,ShenZhe,ShenZhe
02,TianJin,TianJin
D:\Orion>
|
◆控制文件
D:\Orion>cat data.ctl
LOAD DATA
INFILE 'data.txt'
APPEND INTO TABLE test1
WHEN (2) = '1'
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY " " TRAILING NULLCOLS
( a1 POSITION(01:02), a2 POSITION(04:10), a3 POSITION(12:19) )
INTO TABLE test2
WHEN (2) = '2'
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY " " TRAILING NULLCOLS
( a1 POSITION(01:02), a2 POSITION(04:10), a3 POSITION(12:19) )

◆加载数据
D:\Orion>sqlldr eygle/eygle errors=20000 log=data.log control=data.ctl
SQL*Loader: Release 9.2.0.6.0 - Production on 星期一 11月 11 12:23:21 2007

达到提交点，逻辑记录计数3
达到提交点，逻辑记录计数4

◆检查结果
D:\Orion>sqlplus eygle/eygle

注释：假如你不选择分区表，就可以用这个方式来直接加载数据到不同的数据表中。
