Occurs before a table or view contained in the database is opened. There are two versions of the syntax.
PROCEDURE dbc_BeforeOpenTable(cTableName) |
PROCEDURE dbc_BeforeOpenTable LPARAMETERS cTableName |
Parameters
- cTableName
- Specifies the name of the table or view being opened.
Remarks
You can use method code in the dbc_BeforeOpenTable event to track attempted access before a table is opened in the database. This event occurs anytime a table or view in the database is opened either explicitly by the USE command or implicitly by other commands such as SELECT.
If the underlying tables are not open when a view is opened, this event occurs for both the tables and the view. The dbc_BeforeOpenTable event receives the name of the table as the parameter and not the cursor name.
Return .F. from this procedure to prevent the table from being opened.
