dbc_BeforeDropView Event
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.
Example
* Reports to the screen Event name, where it is called from and ;
* the parameter passed.
PROCEDURE dbc_BeforeDropView ;
(cViewName)
? '>> ' + PROGRAM()
?? ' in ' + SUBSTR(SYS(16),RAT('\',SYS(16))+1)
? ' cViewName = ' + TRANSFORM(cViewName) + ' - ' ;
+ TYPE('cViewName ')+' /end/ '
ENDPROC
