我想排序给予列升序和降序按月份和年份按字母顺序排列

monthtext <-----(column Name in varchar) 

'2016july'    
'2016september'  
'2016december'   
'2016january'   
'2017february'  
'2017june' 
'2017march'

我想排序按升序或降序不是按字母顺序。应该要考虑的月份和年份排序我想排序给予列升序和降序按月份和年份按字母顺序排列

升序答案应该是像

'2016 january' 
'2016 july' 
'2016 saptember' 
'2016 december' 
'2017 february' 
'2017 march' 
'2017 june'

mysql或SQL-Server？ – Jens

我正在使用sql-server，我需要在sql-server – Rahul

你可以使用这个，如果所有的日期是有效的：

SELECT monthtext 
FROM 
    (values 
    ('2016july'),('2016september'),('2016december'),('2016january'), 
    ('2017february'),('2017june'),('2017march')) x(monthtext) 
ORDER BY cast(monthtext as date)

太棒了！这是一个简单的方法.. –

谢谢你sir @ShakeerMirza它的工作很好回答简单的方法。 – Rahul

事情是这样的：

你应该再添个月也case声明

select t.* from (
    select '2016july' as str union all 
    select '2016september' union all 
    select '2016december' union all 
    select '2016january' union all 
    select '2017february' union all 
    select '2017june' union all 
    select '2017march' 
)t 
order by 
    cast(substring(str, 1, 4) as int), 
    case 
     when substring(str, 5, len(str)) = 'january' then 1 
     when substring(str, 5, len(str)) = 'february' then 2 
     when substring(str, 5, len(str)) = 'march' then 3 
     when substring(str, 5, len(str)) = 'june' then 6 
     when substring(str, 5, len(str)) = 'july' then 7 
     when substring(str, 5, len(str)) = 'september' then 9 
     when substring(str, 5, len(str)) = 'december' then 12 
    end

@Oto Shavadze先生你钉了它。那是正确的，谢谢你！ – Rahul

@Rahul - 不客气 –

您需要将其拆分为年份&月然后应用Order By子句。

模式：

CREATE TABLE #TAB (NAME VARCHAR(50)) 

INSERT INTO #TAB 
SELECT '2016july' 
UNION ALL 
SELECT '2016september' 
UNION ALL 
SELECT '2016december' 
UNION ALL 
SELECT '2016january' 
UNION ALL 
SELECT '2017february' 
UNION ALL 
SELECT '2017june' 
UNION ALL 
SELECT '2017march'

现在不要选择像下面

SELECT NAME 
, CAST(SUBSTRING(NAME, 1, PATINDEX('%[a-z]%',NAME)-1) AS INT) YEAROF 
,DATEPART(MM, SUBSTRING(NAME,PATINDEX('%[a-z]%',NAME),LEN(NAME)) +' 01 2017') MONTHOF 
FROM #TAB 
ORDER BY YEAROF,MONTHOF

结果：

+---------------+--------+---------+ 
|  NAME  | YEAROF | MONTHOF | 
+---------------+--------+---------+ 
| 2016january | 2016 |  1 | 
| 2016july  | 2016 |  7 | 
| 2016september | 2016 |  9 | 
| 2016december | 2016 |  12 | 
| 2017february | 2017 |  2 | 
| 2017march  | 2017 |  3 | 
| 2017june  | 2017 |  6 | 
+---------------+--------+---------+
