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* FROMtabl
复制代码 代码如下:Select * FROM table1 Where (ID IN (3,5,1,4,2)) 复制代码 代码如下:Select * FROM table1 Where (ID IN (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 * FROM table1 Where (ID IN (3,5,1,4,2)) orDER BY CHARINDEX(',' + CONVERT(nvarchar, ID) + ',', ',' + CONVERT(nvarchar, Replace('3,5,1,4,2', ' ','')) + ',') 复制代码 代码如下: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 * 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', ',',' , ')) + ' ') 复制代码 代码如下: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 * FROM table1 Where (ID IN (3,5,1,4,2)) orDER BY FIND_IN_SET(ID, '3,5,1,4,2')
