Database events are triggered by certain database operations. They can have code associated with them that is run automatically when the event occurs.
|DBC_AFTERDELETE||Occurs after a delete operation|
|DBC_AFTERINSERT||Occurs after an insert operation|
|DBC_AFTEROPENTABLE||Occurs on an open table operation after the table has been opened (from v5.0)|
|DBC_AFTERUPDATE||Occurs after an update operation|
|DBC_BEFOREDELETE||Occurs before a delete operation|
|DBC_BEFOREINSERT||Occurs before an insert operation|
|DBC_BEFOREOPENTABLE||Occurs on an open table operation before the table has been opened (from v5.0)|
|DBC_BEFOREUPDATE||Occurs before an update operation|
|DBC_CLOSEDATA||Occurs when a database is closed|
|DBC_OPENDATA||Occurs when a database is opened|
When a database is opened, if dbc_library.prg (.dbo compiled/runtime) procedure library file exists, it is loaded as a system library.
Programs associated with database events should reside in the relevant database's directory.
These can be created and modified from the Events tab in the Data Workspace when a database is open.
