Mysql inq-查询多个表的结果

我正在编写一个问题跟踪脚本，查看mysql语句，我能够获得所有优先级问题的计数，但无法获得状态的计数

如何使用下面的mysql语句检索状态计数

tbl_status
index    status
 1         open
 2         closed
 3         pending

tbl_priority
index      priority
1           low
2           medium
3             high


tbl_incident
incident  priority   status
adfadf        1          2
adfsdf        2          2
adfadf        1          1
adfadf        3          2
adfasdf       1          3

我能够将优先级分组如下（工作）：

喜欢与状态相同的结果，但它不起作用。也许一句话要求太多了

open 1
closed 3
high 1

也许一句话要求太多了

open 1
closed 3
high 1

是的，试着为每个问题分开陈述。依我看，这样会更有效率

对于状态：

select tbl_status.status, count(*)
from tbl_incident 
    inner join tbl_status on tbl_status.index = tbl_incident.status
group by tbl_status.status;

至于优先事项：

select tbl_priority.priority, count(*)
from tbl_incident 
    inner join tbl_priority on tbl_priority.index = tbl_incident.priority
group by tbl_priority.priority;

select tbl_priority.priority, count(*)
from tbl_incident 
    inner join tbl_priority on tbl_priority.index = tbl_incident.priority
group by tbl_priority.priority;
