views structure is not refreshing

If the underlying structure of the view changes , then the views which are referring these objects wont refresh always with the new structure.
Below script will loop through all the views and executes the sp_refreshview on each view.
Note :  used the implicit transaction , else if any statement fails then the rest of the execute statements in this loop wont execute though its using Begin Try and Catch.

create proc refresh_views as set nocount on set xact_abort on   declare @vwname varchar(256) declare @err varchar(max) = '' declare cur cursor for select TABLE_SCHEMA+'.'+TABLE_NAME FROM INFORMATION_SCHEMA.views open cur fetch next from cur into @vwname while @@FETCH_STATUS = 0         begin                 begin try                 -- It has to be in a transaction , else if any statement fails then the rest of the execute statements in this loop wont execute though its using Begin Try and Catch                 BEGIN TRAN                 EXECUTE sp_refreshview @vwname                 COMMIT TRAN                 end try                                 begin catch                 ROLLBACK TRAN                                 set @err = @err +','+@vwname+':'+ERROR_MESSAGE()                                 end catch                                         fetch next from cur into @vwname continue         end close cur deallocate cur if @err <> '' begin select 'Sync Has the errors while refreshing the follwing views   '+@err end
