MySQL資料移轉到Oracle記錄

來源:互聯網
上載者:User

MySQL: utf-8字元集

Oracle: Al32UTF8

步驟:

1. 從mysql匯出csv格式資料,匯出時設定default_character_set=gbk,否則會亂碼

2.上傳至linux伺服器(oracle伺服器),用以下命令將windows的\r\n換成\r:

   sed -i "s/\r//g" file

3.將gbk編碼轉為utf8編碼:

iconv -f gb18030 -t utf-8 file1.txt > file2.txt

4.編寫sql loader控制項檔案(file.ctl):

options (skip=1)
load data
CHARACTERSET AL32UTF8
infile 'terminal.txt'
badfile 'terminal.err'
discardfile 'terminal.dis'
replace into table terminal
fields terminated by ',' TRAILING NULLCOLS
(
id,
mobile,
imsi,
imei,
evoketime date "yyyy-mm-dd hh24:mi:ss",
province,
city,
evokenum,
createtime date "yyyy-mm-dd hh24:mi:ss",
project_id,
carrier,
ip,
sc,
new_imsi,
new_imei
)

5. 運行sqlldr匯入到oracle資料庫:

sqlldr user/pass@db -control=file.ctl
