我有这样的表结构。表名是z_notes
v_resident_fname
(基本上是一个名字)
i_communication_log
(布尔值,包含0或1,0表示常规注释,1表示关键注释)
dt_note_created
(日期)
所以我需要做的是,首先我想要所有的名字以及它们的计数wherei_communication_log = 0
和。dt_note_created < 1332792382
dt_note_create > 1332792382
所以这个查询是:
SELECT v_resident_fname as Name, COUNT( * ) AS Critical_Notes
FROM z_notes
WHERE dt_note_created >1332792382
AND dt_note_created <1332892382
AND `i_communication_log` = 1
GROUP BY v_resident_fname
返回:
______________________
|Name |Critical_Notes|
| abc | 7 |
| xyz | 4 |
另一个查询是相同的,但 i_communcation_log = 0
SELECT v_resident_fname as Name, COUNT( * ) AS Routine_Notes
FROM z_notes
WHERE dt_note_created >1332792382
AND dt_note_created <1332892382
AND `i_communication_log` = 0
GROUP BY v_resident_fname
_____________________
|Name |Routine_Notes |
| abc | 3 |
| xyz | 4 |
我想根据 Name 将这两个查询组合为一个查询,以便最终结果类似于:
____________________________________
|Name |Critical_Notes|Routine_Notes|
| abc | 7 | 3 |
| xyz | 4 | 4 |
