我执行了以下查询
select employee_name, max(employee_dept) as dept
from employeeDB
where employee_name is not null and employee_name != ''
group by employee_name
order by employee_name asc
limit 1000
执行操作时出现错误:ERROR: XX000: 磁盘已满
。
通过执行以下查询进行调查,我发现我有941GB的可用空间和5000GB的已用空间。
select
sum(capacity)/1024 as capacity_gbytes,
sum(used)/1024 as used_gbytes,
(sum(capacity) - sum(used))/1024 as free_gbytes
from
stv_partitions where part_begin=0;
有人能建议如何缓解这个挑战,以便我能获得所需的结果吗?
