Синтаксис

'Декларация
Public ReadOnly Property IndexSqlStatements As StringCollection

public StringCollection IndexSqlStatements { get; }

public:
property StringCollection^ IndexSqlStatements {
    StringCollection^ get ();
}

/** @property */

public function get IndexSqlStatements () : StringCollection

Значение свойства

A StringCollection containing the indexing Transact-SQL statements.

Замечания

Indexing statements are optional. Creating the proper indexes on an event class can help improve performance for event chronicle rules and subscription rules.

Use the StringCollection methods to modify the statements.

If you alter the indexing statements, updating the application deletes and re-creates the event class to which it corresponds. This includes dropping and re-creating the Microsoft SQL Server tables and indexes used by this event class. Any data existing in the original SQL Server tables is permanently deleted.

Пример

The following examples show how to define an index on an event class:

// Add an index to the event class to help improve performance
flightEvents.IndexSqlStatements.Add(
    "CREATE INDEX FlightEventsIndex ON MyAppSchema.FlightEvents " + 
    "( LeavingFrom, GoingTo );");

' Add an index to the event class to help improve performance.
flightEvents.IndexSqlStatements.Add( _
    "CREATE INDEX FlightEventsIndex " + _
    "ON MyAppSchema.FlightEvents " + _
    "( LeavingFrom, GoingTo );")
