Provides context information for event handlers.
EVENT_PARAMETER ( context-name )
context-name: 'ConnectionID' | 'User' | 'EventName' | 'Executions' | 'NumActive' | 'TableName' | condition-name
context-name One of the preset strings. The strings are case insensitive, and carry the following information:
ConnectionId The connection ID, as returned by
connection_property( 'id' )
User The user ID for the user that caused the event to be triggered.
Executions The number of times the event handler has been executed.
NumActive The number of active instances of an event handler. This is useful if you want to limit an event handler so that only one instance executes at any given time.
TableName The name of the table, for use with RemainingValues.
In addition, you can access any of the valid condition-name arguments to the EVENT_CONDITION function from the EVENT_PARAMETER function.
