MYSQL-實現sqlserver- row_number() over(partition by order by) 分組排序功能

sqlserver:

with Result as
    (
        select SUM(F_DayValue) AS F_Value,F_ZZ_ttBuildID,F_EnergyItemCode 
        from T_EC_EnergyItemDayResult        
        where F_EnergyItemCode like '%000'
        and F_StartDay>=@ldStartDate and F_StartDay<=@ldEndDate
        and F_ZZ_ttBuildID IN (select F_BuildID from T_BD_BuildBaseInfo)
        group by F_ZZ_ttBuildID,F_EnergyItemCode
    )
    select a.F_Value,a.F_ZZ_ttBuildID,b.F_BuildName,a.F_EnergyItemCode,
    ROW_NUMBER() over(partition by a.F_EnergyItemCode order by a.F_Value desc) as nsort 
    from Result a
    left join T_BD_BuildBaseInfo b on a.F_ZZ_ttBuildID=b.F_BuildID

 

mysql:
