  Hi all

  Please help me understand the process on Views in SQL Server

  Table:

  create table viewstest

  (Col1 int, Col2 int, Col3 int)

  go

  insert into viewstest

  values

  ('1', '1', '1')

  ,('2', '2', '2')

  ,('3', '3', '3')

  ,('4', '4', '4')

  ,('5', '5', '5')

  ,('6', '6', '6')

  ,('7', '7', '7')

  View:

  create view [dbo].[VW]

  as

  select * from viewstest

  where Col1 = '1'

  GO

  Ok

  Why is it that when I update or insert data in the view, it also updates the underlying table?

  Is that normal?

  Thanks

  Views are just saved select statements. They aren't tables, they don't store data. Where else would the changes go when you update a view?
