怎么压缩你的case when代码？用ELT( INTERVAL(x, x1,x2,x3,x4) , cat1,cat2,cat3,cat4)

(case when duration>=0*60 and duration<5*60 then "[0-5>"
        when duration>=5*60 and duration<10*60 then "[5-10>"
        when duration>=10*60 and duration<15*60 then "[10-15>"
        else "15 or more" end
        ) as bin 

ELT(INTERVAL(duration,0,60*5,60*10,60*15),'[0-5>','[5-10>','[10-15>','15 or more') as bin
