Occurs before a View is removed from the current database. There are two versions of the syntax.
PROCEDURE dbc_BeforeDropView(cViewName) |
PROCEDURE dbc_BeforeDropView LPARAMETERS cViewName |
Parameters
- cViewName
- Specifies the name of the view to be deleted from the current database.
Remarks
DROP VIEW is almost identical to DELETE VIEW; DROP VIEW is the ANSI SQL standard syntax for deleting a SQL view. Both commands remove a view definition from the active database, but the syntax is slightly different.
You can use the dbc_BeforeDropView event to track attempted access to the database before a view is removed from the database.
Return .F. from this procedure to prevent the view from being dropped.
