mysql將查詢部分數據導出到外部文件的腳本，文件格式替換

mysql將查詢部分數據導出到外部文件的腳本：

mysql -u root -p222222 -e "use ccbdj2014;SELECT A.CERT_NO 證件號碼,A.CUST_NAME 客戶姓名,A.MOBEL 聯繫電話,MOBEL_NUM 交易筆數 FROM CUST_INFO A WHERE CHANEL='02' ORDER BY A.MOBEL_NUM;">/tmp/ccbdj.txt

說明：root：用戶名，222222：密碼，ccbdj2014：數據庫名稱  ， >/tmp/ccbdj.txt：導出到tmp下的ccbdj文件中

注意：腳本文件編碼應該與數據庫編碼格式一致！

生成文件格式：證件號碼客戶姓名 聯繫電話交易筆數

將文件格式替換爲：證件號碼，客戶姓名，聯繫電話，交易筆數  格式代碼如下：

package test;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
