1、连接

 mysql -u username -ppassword -P 3306 -D database -hip

2、列显示:"\G"

mysql> select * from HUMMOCK_BLACK_LIST limit 1 \G;
*************************** 1. row ***************************

             server_name: LoadTest
gmt_modified_microsecond: 1300172398493

 3、去重操作:distinct  

mysql> select distinct  server_name from HUMMOCK_BLACK_LIST limit 10;
+-------------+
| server_name |

| QA-TEST-2   |
| DEV         |
| A-QA-TEST   |
| B-QA-TEST   |
| ?????       |
| online-test |
+-------------+
