复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))

复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))如果In后面的条件都是数字,那MSSQL排序应该为


复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))
orDERBYCHARINDEX(','+CONVERT(nvarchar,ID)+',',','+CONVERT(nvarchar,Replace('3,5,1,4,2','',''))+',')

复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))
orDERBYCHARINDEX(','+CONVERT(nvarchar,ID)+',',','+CONVERT(nvarchar,Replace('3,5,1,4,2','',''))+',')改进方法,不去处理空格,直接改用空格判断.可以用来判断少数有空格的字符条件.

复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))
orDERBYPATINDEX('%'+CONVERT(nvarchar(4000),ID)+'%',''+CONVERT(nvarchar(4000),Replace('3,5,1,4,2',',',','))+'')

复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))
orDERBYPATINDEX('%'+CONVERT(nvarchar(4000),ID)+'%',''+CONVERT(nvarchar(4000),Replace('3,5,1,4,2',',',','))+'')

其实还是在SQL外处理好条件字符串再进行查询和排序比较好.
对于MYSQL排序可能要改为(MYSQL不熟):

复制代码 代码如下:
Select*
FROMtable1
Where(IDIN(3,5,1,4,2))
orDERBYFIND_IN_SET(ID,'3,5,1,4,2')
