i using microsoft sql server management studio. new sql , not know how start going solving apologize in advance lack of attempted solutions. simplified example of current sql query follows:
use [database] go select [id] ,[value1] ,[max1] ,[value2] ,[max2] [datatable]
which yields so:
[id] [value1] [max1] [value2] [max2] [1] [2] [0] [9] [1] [1] [4] [0] [3] [0] [1] [8] [1] [5] [0] [1] [5] [0] [6] [0] [2] [1] [0] [1] [0] [2] [6] [1] [4] [0] [2] [3] [0] [3] [0] [2] [2] [0] [5] [1]
i trying datatable (datatable) select value corresponding binary indicator (max1 , max2 columns value1 , value2 respectively) maximum value id. trying above table become:
[id] [value1] [value2] [1] [8] [9] [2] [6] [5]
if simpler create separate data frame each variable (value1 in separate resultant data frame value2), fine well.
thank you
you can use conditional aggregation pick values corresponding binary values 1.
select [id] ,max(case when [max1] = 1 [value1] end) value1 ,max(case when [max2] = 1 [value2] end) value2 [datatable] group [id]
