求大神-sql语句优化,该怎么处理

求大神---sql语句优化
如下四条sql语句，只有where条件不同，怎样写能让他们更加优化，速度，速度，我要将查询出来的数据放在一个集合中，appID,serviceCode,wayID,都一样，只不过count（ID）不一样

select appID,serviceCode,wayID,count(ID) from CupSmsMT where receipt=0 group by appID,serviceCode,wayID

select appID,serviceCode,wayID,count(ID) from CupSmsMT where receipt>=0 group by appID,serviceCode,wayID

select appID,serviceCode,wayID,count(ID) from CupSmsMT whereresult>=0 group by appID,serviceCode,wayID

select appID,serviceCode,wayID,count(ID) from CupSmsMT where result=0 group by appID,serviceCode,wayID

神马优化，where就一个条件，优化啥？
是要把四条语句的结果合在一起吗？
你的条件有重复，取>=0，在外面判断好了，要不就直接用union all
或者在select处判断

SQL code

select appID,serviceCode,wayID,       sum(case when receipt=0 then 1 else 0 end) as rec0,       sum(case when receipt>0 then 1 else 0 end) as rec1,        sum(case when result=0 then 1 else 0 end) as res0,        sum(case when result>0 then 1 else 0 end) as res1  from CupSmsMT where receipt >= 0 or result >= 0 group by appID,serviceCode,wayID

SQL code
select appID,serviceCode,wayID,count(case when receipt=0 then 1 else null end),count(case when receipt>=0 then 1 else null end),count(case when result>=0 then 1 else null end),count(case when result=0 then 1 else null end) from CupSmsMT  group by appID,serviceCode,wayID
