Description:
Know the view you want to drop, but don't know how to check for existence? Want to drop all views in the system, but have no automated way of doing it? Specify the view name as the parameter to drop only that view (IF it exists). Leave it empty to drop'em all.
Usage:
To drop a single view by name:
call sp_Drop_View('vw_People_Info');
To drop all views in a database:
call sp_Drop_View();
Code:
create procedure sp_Drop_View (IN @viewName varchar(128) DEFAULT 'NONE')
begin
IF @viewName = 'NONE' THEN
FOR VIEW_NAME_FOR as VIEW_NAME_CURSOR dynamic scroll cursor for
select st.table_name as VIEW_NAME
from systab st
where st.creator = 1 AND
st.table_type = 'VIEW'
order by st.table_name asc do
execute immediate 'DROP VIEW ' || VIEW_NAME;
END FOR;
ELSE
if exists(select 1 from sys.systable where table_name=@viewName and table_type='VIEW') then
EXECUTE IMMEDIATE 'DROP VIEW ' || @viewName;
end if;
END IF;
end;

Adding the owner name as a 2nd param (with default "DBA"?) would be nice. E.g. our schemata are usually owned by "dbo" - primarily for historical purposes like compatibility with MS SQL.
