我試圖通過使用排序,但排序不能正常工作,因爲我想Sql Server的排序爲nvarchar場

這裏是我的代碼弄清楚這個數據:

SELECT (SELECT LEFT(SUBSTRING(description, PATINDEX('%[0-9.-]%', description), 8000), 
     PATINDEX('%[^0-9.-]%', SUBSTRING(description, PATINDEX('%[0-9.-]%', description), 8000) + 'X') -1)) as x  
FROM dbo.fn_BMS_PPA() 
WHERE ppayear = 2017 and actualrootppaid = 112905 
and actualmotherppaid != 0 and withchildppa = 0 
ORDER BY x 

輸出是:

1.1.1 
1.1.10 
1.1.11 
1.1.2 
1.1.3 
..... 

我要的是:

1.1.1 
1.1.2 
1.1.3 
1.1.10 
1.1.11 
..... 

請留意,有時它會1.11.1.1.1

您不能使用「數字排序順序」對字符串進行排序。請參閱:https://dba.stackexchange.com/questions/3828/is-there-a-collat​​ion-to-sort-the-following-strings-in-the-follow-order-1-2-3 – Alex
