1、登錄命令
./sqlline.py localhost:2181:/hbase-unsecure

phoenix-sqlline
localhost:2181:/hbase-unsecure

2、退出
!quit

!exit

3、幫助

4、列出metadata信息

5、創建表
create table if not exists ljc.student(id integer primary key,name varchar(20));

6、查看當前庫中存在的表
!tables

phoenix中的表信息都存在SYSTEM.CATALOG表中,也可以通過下面的sql語句查看系統的表信息
select * from SYSTEM.CATALOG;

注意:
1、如果不加雙引號,會自動將小寫轉為大寫
2、phoenix表名區分大小寫
7、刪除表
drop table ljc.student;

8、查看表結構
!describe "METRIC_AGGREGATE"

注意:
phoenix/hbase對表名、字段名都是大小寫敏感,如果直接寫小寫字母,不加雙引號,則默認會被轉換成大寫字母
9、插入、更新
Phoenix中不存在update的語法關鍵字,而是upsert ,功能上替代了Insert+update
upsert into ljc.student(id,name) values(1,'zhangsan');
upsert into ljc.student(id,name) values(2,'lisi');
upsert into ljc.student(id,name) values(3,'wangwu');
upsert into ljc.student(id,name) values(4,'liuping');
upsert into ljc.student(id,name) values(5,'zhouhong');

10、示例SQL
create table if not exists ljc.student(id integer primary key,name varchar(20));
upsert into ljc.student(id,name) values(1,'zhangsan');
upsert into ljc.student(id,name) values(2,'lisi');
upsert into ljc.student(id,name) values(3,'wangwu');
upsert into ljc.student(id,name) values(4,'liuping');
upsert into ljc.student(id,name) values(5,'zhouhong');
create table if not exists ljc.score(id integer primary key,score integer);
upsert into ljc.score(id,score) values(1,98);
upsert into ljc.score(id,score) values(2,87);
upsert into ljc.score(id,score) values(3,90);
upsert into ljc.score(id,score) values(4,80);
upsert into ljc.score(id,score)
