sqlldr裝載數據完成代碼。本站提示廣大學習愛好者：（sqlldr裝載數據完成代碼）文章只能為提供參考，不一定能成為您想要的結果。以下是sqlldr裝載數據完成代碼正文
這裡用 excel 數據做個最簡略的測試。
1）把 excel 數據存為 t.txt 文件，留意文件後綴名為 .txt
1 jhchen 11/07/2005 20:04:00 2005-11-7 20:04
2 jhchen 11/07/2005 20:04:00 2005-11-7 20:04
3 jhchen 11/07/2005 20:04:00 2005-11-7 20:04
2）SQL> create table t_load(
id number,
name varchar2(10),
dat1 date,
dat2 date,
dat3 date
);
Table created.
3）掌握文件 t.ctl 以下
load data
infile 't.txt'
badfile 't.bad'
append into table t_load
fields terminated by X'09'
trailing nullcols
(
id ,
name ,
dat1 date "mm/dd/yyyy hh24:mi:ss",
dat2 date "yyyy-mm-dd hh24:mi:ss"
)
個中，X'09' 是制表符，TAB鍵，trailing nullcols 表現如表的字段沒有對應的值時許可為空。
4）C:\Documents and Settings\cjh>sqlldr userid=jhchen/oracle control=t.ctl

到達提交點，邏輯記載計數3
5）SQL> select * from t_load;

LOAD DATA
INFILE 't.dat' // 要導入的文件
// INFILE 'tt.date' // 導入多個文件
// INFILE * // 要導入的內容就在control文件裡 上面的BEGINDATA前面就是導入的內容
INTO TABLE table_name // 指定裝入的表
BADFILE 'c:\bad.txt' // 指定壞文件地址
************* 以下是4種裝入表的方法
APPEND // 本來的表稀有據 就加在前面
// INSERT // 裝載空表 假如本來的表稀有據 sqlloader會停滯 默許值
// REPLACE // 本來的表稀有據 本來的數據會全體刪除
// TRUNCATE // 指定的內容和replace的雷同 會用truncate語句刪除現存數據
************* 指定的TERMINATED可以在表的開首 也可在表的外部字段部門
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
// 裝載這類數據: 10,lg,"""lg""","lg,lg"
// 在表中成果: 10 lg "lg" lg,lg
// TERMINATED BY X '09' // 以十六進制格局 '09' 表現的
// TERMINATED BY WRITESPACE // 裝載這類數據: 10 lg lg
TRAILING NULLCOLS ************* 表的字段沒有對應的值時許可為空
************* 上面是表的字段
(
col_1 , col_2 ,col_filler FILLER // FILLER 症結字 此列的數值不會被裝載
// 如: lg,lg,not 成果 lg lg
)
// 當沒聲明FIELDS TERMINATED BY ',' 時
// (
// col_1 [interger external] TERMINATED BY ',' ,
// col_2 [date "dd-mon-yyy"] TERMINATED BY ',' ,
// col_3 [char] TERMINATED BY ',' OPTIONALLY ENCLOSED BY 'lg'
// )
// 當沒聲明FIELDS TERMINATED BY ','用地位告知字段裝載數據
// (
// col_1 position(1:2),
// col_2 position(3:10),
// col_3 position(*:16), // 這個字段的開端地位在前一字段的停止地位
// col_4 position(1:16),
// col_5 position(3:10) char(8) // 指定字段的類型
// )
BEGINDATA // 對應開端的 INFILE * 要導入的內容就在control文件裡
