SQL99 Syntax and Description
DROP VIEW view_name RESTRICT | CASCADE
In the SQL99 syntax, RESTRICT
tells the DBMS to
prohibit the drop if views or assertions that currently reference the
table are to be dropped. The CASCADE
clause
causes any referencing objects to be dropped along with the view.
This command is not currently supported by MySQL.
Microsoft SQL Server Syntax and Variations
DROP VIEW [owner_name.]view_name [,...n] GO
Microsoft SQL Server allows multiple views to be dropped in a single command by placing a comma between each view name. The views must reside in the same database. Information about the view is removed from all system tables.
Oracle Syntax and Variations
DROP VIEW [owner_name.]view_name;
As with other Oracle DROP
commands, the owner
name may be specified along with the view name. Users with the system
privilege, DROP ANY VIEW,
may drop views owned
by other users.
PostgreSQL Syntax and Variations
DROP VIEW view_name;
In PostgreSQL, the DROP VIEW
command drops an
existing view from the current database. Only the owner of the view
may drop it. The PostgreSQL command DROP
TABLE
also can be used to drops views.
