in my sql stored procedure i'm using 2 select query and its showing 2 outputs separately(as two rows result) . In my code behind i'm taking the output using sqlreaderdata (sqlreaderdata dr). I'm getting first output value(using dr[0]...), but what i want is second output value. how will i get the second output value..

first select query result shows like

34 10 10

ie, columnone value=34, columntwo value=10 columnthree value=10



here dr[0]=34
dr[1]=10
dr[3]=10

second select query output

columnone

34:10:10

what i want is "34:10:10"...how will i get it.
