我在使用复杂的MySQL查询时遇到了一些麻烦。我想从这个查询中获取3列。过程的名称,每个过程的站点总数以及每个过程的医师总数(用户总数)。我正在关联2个表格,procedures
和tbl_syn_procedure
。
只有一个条件可以让我的医生总数(用户总数)和procedures.phys_id = '##'
,但我不知道如何将其纳入查询。
我目前有一个大型查询,它提供了我需要的一半数据。
SELECT
IFNULL( Synoptic, 'Total Count') AS Synoptic, Total
FROM (
SELECT
Synoptic,
SUM( Data ) AS Total
FROM (
SELECT
tbl_syn_procedure.name AS 'Synoptic',
COUNT(*) AS Data
FROM procedures
JOIN tbl_syn_procedure ON
procedures.proc_synoptic_id = tbl_syn_procedure.name_id
GROUP BY procedures.proc_synoptic_id
) AS stats
GROUP BY Synoptic WITH ROLLUP
) AS stats
这给了我一个两列表,如下所示:
摘要--------------------------总计
APBI设备插入---------- 1328
MRI引导活检------------- 71
立体定向活组织检查------------- 10504
总计数---------------------- 11903
但是你可以看到它缺少了医生总数(用户总数)。如果有人能就如何将第三列添加到查询中给我一些建议。
答案 0 :(得分:0)
试试这个
select
count(p.proc_synoptic_id), p.proc_synoptic_id, name, num_phys_procedures
from
procedures p
inner join tbl_syn_procedure on p.proc_synoptic_id = tbl_syn_procedure.name_id
left join
(
select count(proc_synoptic_id) as num_phys_procedures, proc_synoptic_id from procedures
where phys_id = ##
group by proc_synoptic_id
) phys_procedures on p.proc_synoptic_id = phys_procedures.proc_synoptic_id
group by proc_synoptic_id, name;
它首先得到程序总数,然后连接到派生表phys_procedures
,该表具有特定医生的程序数。
