在mysql视图中传递参数

我从一个表中创建了两个视图。第一个视图是主视图，第二个视图是使用第一个视图创建的。我想在第一个视图中传递参数，在第二个视图中得到结果……下面是我在mysql中的视图

create view dealermth1_view as
      select a.glc,a.docdt,b.gln,(month(docdt)) as mth,a.qty from sale a,glmast b where a.glc=b.glc and b.flag3='N'


create view dealermth2_view as
select glc,gln,mth,qty as qty1,0000000000.000 as qty2,0000000000.000 as qty3,0000000000.000 as qty4,0000000000.000 as qty5,0000000000.000 as qty6,0000000000.000 as qty7,0000000000.000 as qty8,0000000000.000 as qty9,0000000000.000 as qty10,0000000000.000 as qty11,0000000000.000 as qty12 from dealermth1_view where mth=1
union
select glc,gln,mth,0000000000.000 as qty1,qty as qty2,0000000000.000 as qty3,0000000000.000 as qty4,0000000000.000 as qty5,0000000000.000 as qty6,0000000000.000 as qty7,0000000000.000 as qty8,0000000000.000 as qty9,0000000000.000 as qty10,0000000000.000 as qty11,0000000000.000 as qty12 from dealermth1_view where mth=2
union
select glc,gln,mth,0000000000.000 as qty1,0000000000.000 as qty2,qty as qty3,0000000000.000 as qty4,0000000000.000 as qty5,0000000000.000 as qty6,0000000000.000 as qty7,0000000000.000 as qty8,0000000000.000 as qty9,0000000000.000 as qty10,0000000000.000 as qty11,0000000000.000 as qty12 from dealermth1_view where mth=3

我想做这样的事情

select * from dealermth1_view where mth='2'

---

在第二个视图dealermth2_视图中，它必须只显示2个月的记录，因为我显然需要50个代表来评论，我将添加这一点作为答案
