oracle sqlldr控制文件模板

 Sqlldr userid=lgone/tiger control=a.ctl
 LOAD DATA
 INFILE 't.dat' // 要导入的文件
 // INFILE 'tt.date' // 导入多个文件
 // INFILE * // 要导入的内容就在control文件里 下面的BEGINDATA后面就是导入的内容, *和't.dat'不能同时存在
 INTO TABLE table_name // 指定装入的表
 BADFILE 'c:bad.txt' // 指定坏文件地址
 ************* 以下是4种装入表的方式
 APPEND // 原先的表有数据 就加在后面
 // INSERT // 装载空表 如果原先的表有数据 sqlloader会停止 默认值
 // REPLACE // 原先的表有数据 原先的数据会全部删除
 // TRUNCATE // 指定的内容和replace的相同 会用truncate语句删除现存数据
 ************* 指定的TERMINATED可以在表的开头 也可在表的内部字段部分
 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
 // 装载这种数据: 10,lg,"""lg""","lg,lg"
 // 在表中结果: 10 lg "lg" lg,lg
 // TERMINATED BY X '' // 以十六进制格式 '' 表示的
 // TERMINATED BY WRITESPACE // 装载这种数据: 10 lg lg
 TRAILING NULLCOLS ************* 表的字段没有对应的值时允许为空
 ************* 下面是表的字段
 (
 col_1 , col_2 ,col_filler FILLER // FILLER 关键字 此列的数值不会被装载
 // 如: lg,lg,not 结果 lg lg
 )
 // 当没声明FIELDS TERMINATED BY ',' 时
 // (
 // col_1 [interger external] TERMINATED BY ',' ,
 // col_2 [date "dd-mon-yyy"] TERMINATED BY ',' ,
 // col_3 [char] TERMINATED BY ',' OPTIONALLY ENCLOSED BY 'lg'
 // )
 // 当没声明FIELDS TERMINATED BY ','用位置告诉字段装载数据
 // (
 // col_1 position(1:2),
 // col_2 position(3:10),
 // col_3 position(*:16), // 这个字段的开始位置在前一字段的结束位置
 // col_4 position(1:16),
 // col_5 position(3:10) char(8) // 指定字段的类型
 // )
 BEGINDATA // 对应开始的 INFILE * 要导入的内容就在control文件里
