Dropping all View under particular schema - SQL - sql-server-2008

Question

How to drop all views under particular schema.
Ex: if I got below views in db.
[dbo].[view1]
[dbo].[veiw2]
[dbo].[view3]
[myView].[view1]
[myView].[veiw2]
[myView].[view3]
I just want to drop all views under schema myView all at a time.

Answer 1

Try this:
select 'drop view ' + QUOTENAME(sc.name) + '.' + QUOTENAME(obj.name) + ';'
from sys.objects obj
INNER JOIN sys.schemas sc
ON sc.schema_id = obj.schema_id
where obj.type='V'
and sc.name = 'myView';

Answer 2

I have tons of views (so, just aggregate drop query to one nvarchar(max) doesnt work - the query is truncated.) and i want to except some of views from deletion.
In this example, i want to drop every view from every schema beginnig with usr_* but not usr_test, usr_usr, usr_usr1, usr_usr2 and usr_usr3.
cursor is used because i dont care about few ms. This view cleaning query is used before integration tests, its not really speed-critical (and yet it perform really well)
declare drop_view_cursor cursor for
select 'drop view ' + QUOTENAME(sys.schemas.name) + '.' + QUOTENAME(sys.views.name) + ';'
from sys.views
inner join sys.schemas on sys.schemas.schema_id = sys.views.schema_id
where sys.schemas.schema_id in
(
select s.schema_id
from sys.schemas as s
where s.name like 'usr_%'
and s.name not in ('usr_test', 'usr_usr', 'usr_usr1', 'usr_usr2', 'usr_usr3')
)
declare #sql nvarchar(max)
open drop_view_cursor
fetch next from drop_view_cursor into #sql
while ##FETCH_STATUS = 0
begin
exec (#sql)
fetch next from drop_view_cursor into #sql
end
close drop_view_cursor
deallocate drop_view_cursor

This takes into account Schema, uses the system tables, and outputs to a variable that may then be executed. This way you don't have the problem of your Select truncating your script, because the Select and Print statements are limited on the length of what they may return.
The following runs in SQL Server 2008:
DECLARE #DropViewCommand nVarChar(MAX) = ''
SELECT #DropViewCommand = #DropViewCommand
+ 'DROP VIEW '+ QUOTENAME(S.Name) + '.' + QUOTENAME(V.name) + '; '
FROM sys.views as V
JOIN sys.schemas as S
ON S.schema_id = V.schema_id
WHERE S.name = 'dbo'--Selectively delete by Schema. Comment out to delete all views.
PRINT #DropViewCommand--See the command used in dropping all views (will be truncated in Select/Print, but not when Executing).
EXEC (#DropViewCommand)

Re-posting answer for those looking for specific solution. Put DROP view code in WHILE loop as shown below:
DECLARE #name VARCHAR(128)
DECLARE #SQL VARCHAR(254)
DECLARE #schema VARCHAR(128)
SELECT #name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'V' AND category = 0 ORDER BY [name])
SELECT #schema = (SELECT TOP 1 schema_name(schema_id) FROM sys.views WHERE [name] = #name)
WHILE #name IS NOT NULL
BEGIN
SELECT #SQL = 'DROP VIEW [' + #schema + '].[' + RTRIM(#name) +']'
EXEC (#SQL)
PRINT 'Dropped View: ' + #name
SELECT #name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'V' AND category = 0 AND [name] > #name ORDER BY [name])
SELECT #schema = (SELECT TOP 1 schema_name(schema_id) FROM sys.views WHERE [name] = #name)
END
