this question has answer here:

today noticed when alter table in view, syscolumns of view not updated without run sp_refreshview. code bellow show i'm talking about

create table test ( n1 decimal(12,4) ) go create view vtest select * test; go sp_help vtest go alter table test alter column n1 decimal(12,2) go sp_help vtest

note vtest stay static, there someway automate process ?

you need call sp_refreshview update view 

create table test ( n1 decimal(12,4) ) go create view vtest select * test; go sp_help vtest go alter table test alter column n1 decimal(12,2) exec sp_refreshview  vtest go sp_help vtest
