> For The sql:
> {code:java}
> select * from emp tablesample bernoulli(0) where empno > 5
> {code}
> The plan is :
> {code:java}
> LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4],
> SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8])
> LogicalFilter(condition=[>($0, 5)])
> LogicalTableScan(table=[[CATALOG, SALES, EMP]])
> {code}
> I think the correct result of above SQL is empty.
> But its result is the following SQL result:
> {code:java}
> select * from emp where empno > 5
> {code}
> It's an incorrect result
