-- 单分区测试
-- ============================================================

-- 1. 插入单分区数据
insert into /test/aaa/test_partition (p_id, p_name, p_value) values (1, 'part1_item1', 100)
;

insert into /test/aaa/test_partition (p_id, p_name, p_value) values (1, 'part1_item2', 200)
;

insert into /test/aaa/test_partition (p_id, p_name, p_value) values (2, 'part2_item1', 300)
;

insert into /test/aaa/test_partition (p_id, p_name, p_value) values (2, 'part2_item2', 400)
;

-- 2. 查询单分区数据
select * from /test/aaa/test_partition where p_id=1
/**
output()
**/
;

-- 3. 跨分区查询
select * from /test/aaa/test_partition
/**
output()
**/
;

-- 4. 按分区聚合
select p_id, count(*) from /test/aaa/test_partition group by p_id
/**
output()
**/
;

-- 5. 更新单分区数据
update /test/aaa/test_partition set p_value=150 where p_id=1 and p_name='part1_item1'
;

select p_value from /test/aaa/test_partition where p_id=1 and p_name='part1_item1'
/**
output()
match("p_value","150")
**/
;

-- 6. 删除单分区数据
delete from /test/aaa/test_partition where p_id=2 and p_name='part2_item2'
;

select * from /test/aaa/test_partition where p_id=2 and p_name='part2_item2'
/**
output()
count(0)
**/
;
