sql 多条件查询的一种简单的方法

以后我们做多条件查询,一种是排列结合,另一种是动态拼接SQL
如:我们要有两个条件,一个日期@addDate,一个是@name
第一种写法是
if (@addDate is not null) and (@name <> '')
select * from table where addDate = @addDate and name = @name
else if (@addDate is not null) and (@name ='')
select * from table where addDate = @addDate
else if(@addDate is null) and (@name <> '')
select * from table where and name = @name
else if(@addDate is null) and (@name = '')
select * from table
第二种就是动态组成SQL,通过exec来执行，我就不写，
昨天我想到一种办法
select * from table where (addDate = @addDate or @addDate is null) and (name = @name or @name = '')
结果一调试，成功，
一点想法，有更好方法的，请指教！～
