復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))
復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))如果In后面的條件都是數(shù)字,那MSSQL排序應(yīng)該為
復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))
orDER BY CHARINDEX(',' + CONVERT(nvarchar, ID) + ',', ',' + CONVERT(nvarchar, Replace('3,5,1,4,2', ' ','')) + ',')
復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))
orDER BY CHARINDEX(',' + CONVERT(nvarchar, ID) + ',', ',' + CONVERT(nvarchar, Replace('3,5,1,4,2', ' ','')) + ',')改進(jìn)方法,不去處理空格,直接改用空格判斷.可以用來(lái)判斷少數(shù)有空格的字符條件.
復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))
orDER BY PATINDEX('% ' + CONVERT(nvarchar(4000), ID) + ' %', ' ' + CONVERT(nvarchar(4000), Replace('3,5,1,4,2', ',',' , ')) + ' ')
復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))
orDER BY PATINDEX('% ' + CONVERT(nvarchar(4000), ID) + ' %', ' ' + CONVERT(nvarchar(4000), Replace('3,5,1,4,2', ',',' , ')) + ' ')
其實(shí)還是在SQL外處理好條件字符串再進(jìn)行查詢和排序比較好.
對(duì)于MYSQL排序可能要改為(MYSQL不熟):
復(fù)制代碼 代碼如下:
Select *
FROM table1
Where (ID IN (3,5,1,4,2))
orDER BY FIND_IN_SET(ID, '3,5,1,4,2')
