有效的关键字:
userid -- ORACLE username/password
control -- Control file name
log -- Log file name
bad -- Bad file name
data -- Data file name
discard -- Discard file name
discardmax -- Number of discards to allow (全部默认)
skip -- Number of logical records to skip (默认0)
load -- Number of logical records to load (全部默认)
errors -- Number of errors to allow (默认50)
rows -- Number of rows in conventional path bind array or between direct p
ath data saves
(默认: 常规路径 64, 所有直接路径)
bindsize -- Size of conventional path bind array in bytes(默认256000)
silent -- Suppress messages during run (header,feedback,errors,discards,part
itions)
direct -- use direct path (默认FALSE)
parfile -- parameter file: name of file that contains parameter specification
s
parallel -- do parallel load (默认FALSE)
file -- File to allocate extents from
skip_unusable_indexes -- disallow/allow unusable indexes or index partitions(默
认FALSE)
skip_index_maintenance -- do not maintain indexes, mark affected indexes as unus
able(默认FALSE)
readsize -- Size of Read buffer (默认1048576)
external_table -- use external table for load; NOT_USED, GENERATE_ONLY, EXECUTE(
默认NOT_USED)
columnarrayrows -- Number of rows for direct path column array(默认5000)
streamsize -- Size of direct path stream buffer in bytes(默认256000)
multithreading -- use multithreading in direct path

resumable_name -- text string to help identify resumable statement
resumable_timeout -- wait time (in seconds) for RESUMABLE(默认7200)
date_cache -- size (in entries) of date conversion cache(默认1000)
PLEASE NOTE: 命令行参数可以由位置或关键字指定
。前者的例子是 'sqlload
scott/tiger foo'; 后一种情况的一个示例是 'sqlldr control=foo
userid=scott/tiger'.位置指定参数的时间必须早于
但不可迟于由关键字指定的参数。例如,
允许 'sqlldr scott/tiger control=foo logfile=log', 但是
不允许 'sqlldr scott/tiger control=foo log', 即使
参数 'log' 的位置正确。

三:sql loader使用例子
a)SQLLoader将 Excel 数据导出到
1.创建SQL*Loader输入数据所需要的文件,均保存到C:\,用记事本编辑:
控制文件:input.ctl,内容如下:
load data --1、控制文件标识
infile 'test.txt' --2、要输入的数据文件名为test.txt
append into table test --3、向表test中追加记录
fields terminated by X'09' --4、字段终止于X'09',是一个制表符(TAB)
(id,username,password,sj) -----定义列对应顺序
a、insert,为缺省方式,在数据装载开始时要求表为空
b、append,在表中追加新记录
c、replace,删除旧记录,替换成新装载的记录
d、truncate,同上
在DOS窗口下使用SQL*Loader命令实现数据的输入
C:\>sqlldr userid=system/manager control=input.ctl
默认日志文件名为:input.log
默认坏记录文件为:input.bad
2.还有一种方法
可以把EXCEL文件另存为CSV(逗号分隔)(*.csv),控制文件就改为用逗号分隔
LOAD DATA
INFILE 'd:\car.csv'
APPEND INTO TABLE t_car_temp
FIELDS TERMINATED BY ","
(phoneno,vip_car)
b)在控制文件中直接导入数据
1、控制文件test.ctl的内容
-- The format for executing this file with SQL Loader is:
-- SQLLDR control=
-- version of SQL LOADER and the filename for this file.
LOAD DATA
INFILE *
BADFILE 'C:\Documents and Settings\Jackey\桌面\WMCOUNTRY.BAD'
DISCARDFILE 'C:\Documents and Settings\Jackey\桌面\WMCOUNTRY.DSC'
INSERT INTO TABLE EMCCOUNTRY
Fields terminated by ";" Optionally enclosed by '"'
