Stored procedures 关键字“convert”附近的语法不正确

我有程序

create procedure dbo.updateView(@cobdate datetime)
as
begin
    Update hir_view set ValidTo=@cobdate where  HierarchyId in (
      select distinct HierarchyId from hir_organisation where ValidTo<getDate() and HierarchyId not in (
        select HierarchyId from hir_organisation where ValidTo>getDate()
      ) 
    ) and ValidTo>getDate()

end
go

我得到了错误声明 查找错误-Msg 156，级别15，状态34，服务器DSLNPHX02，第18行-Sybase数据库错误：关键字“convert”附近的语法不正确

---

我不确定哪里出错了

语法正确，您是否尝试过像这样运行update命令

convert(dateTime,'20160209') 

 Update hir_view set ValidTo=convert(dateTime,'20160209')  where  HierarchyId in (
      select distinct HierarchyId from hir_organisation where ValidTo<getDate() and HierarchyId not in (
        select HierarchyId from hir_organisation where ValidTo>getDate()
      ) 
    ) and ValidTo>getDate()

convert(dateTime,'20160209') 

 Update hir_view set ValidTo=convert(dateTime,'20160209')  where  HierarchyId in (
      select distinct HierarchyId from hir_organisation where ValidTo<getDate() and HierarchyId not in (
        select HierarchyId from hir_organisation where ValidTo>getDate()
      ) 
    ) and ValidTo>getDate()
