What's Wrong?

select语句中包含count() over()等开窗函数时，最后使用了分页查询limit xxx offset xxx，如果limit前没有order by子句，则无法查询出数据

What You Expected?

即使不加order by , 也正常返回数据

How to Reproduce?

create database demo;
CREATE TABLE demo.dma_emp (
empno INT NULL,
ename VARCHAR(255) NULL,
job VARCHAR(255) NULL,
mgr INT NULL,
hiredate VARCHAR(255) NULL,
sal FLOAT NULL,
comm FLOAT NULL,
deptno INT NULL
) ENGINE=OLAP
DUPLICATE KEY(empno, ename)
DISTRIBUTED BY HASH(empno) BUCKETS 10
;

INSERT INTO demo.dma_emp VALUES (7788, 'SCOTT', 'ANALYST', 7566, '1987-04-19', 3000, 0, 20);
INSERT INTO demo.dma_emp VALUES (7844, 'TURNER', 'SALESMAN', 7698, '1981-09-08', 1500, 0, 30);

INSERT INTO demo.dma_emp VALUES (7900, 'JAMES', 'CLERK', 7698, '1981-12-03', 950, 0, 30);

-- 1、不加order by 无法返回数据
select
count() over() sal_order,
t.*
from demo.dma_emp t
-- order by sal asc
limit 2 offset 2;

-- 2、不加order by 无法返回数据
select
row_number() over(order by sal desc) sal_order,
t.*
from demo.dma_emp t
-- order by sal asc
limit 2 offset 2;
