mysql 导入导出CSV数据的例子

下面来看两个mysql 导入导出CSV数据的例子,这此都用到了mysql自带的命令了,如 LOAD DATA LOCAL INFILE 或select * INTO OUTFILE命令了.

cvs文件导入MySql数据库命令,代码如下:

1. setnamesutf8;
2. LOADDATALOCALINFILE'C:＼＼resource.csv'
3. INTOTABLEresource
4. FIELDSTERMINATEDBY''
5. LINESTERMINATEDBY'＼r＼n'
6. (title,singer);
7. --phpfensi.com
8. FIELDSTERMINATEDBY----字段终止字符
9. OPTIONALLYENCLOSEDBY----封套符
10. LINESTERMINATEDBY----行终止符

导出一段时间的数据到 cvs,代码如下:

fileName="data"`date --date=$date "+%Y%m%d"`".csv";

#mysql里先导出数据到 xml, 用 select into outfile 导出,设定字段分隔符和记录分隔符.

/usr/local/webserver/mysql/bin/mysql -h "$mysql_host" -u "$mysql_username" --password="$mysql_password" -e "select * INTO OUTFILE '$data_dir$fileName' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '＼"' LINES TERMINATED BY '＼＼n' from $table where InTime>=$minTime && InTime<$maxTime;"

#这一步也很重要， 需要将编码转换为GBK

rm -rf $final_dir$fileName && touch $final_dir$fileName

iconv -c -f UTF-8 -t GBK $data_dir$fileName > $final_dir$fileName

先用select into outfile 把数据从mysql 里边倒出来,其中字段分隔符 ＼t,记录分隔符为 ＼n,然后转一下字符的编码就OK了.
