Initiates a connection to a database.
procedure Connect; overload;
Call Connect to initiate a connection to the database.
The database to which the connection is established, is specified by TEntityConnection.ProviderName and TEntityConnection.DialectName properties. The connection parameters are passed through the TEntityConnection.ConnectionString property.
Calling Connect generates a TEntityConnection.BeforeConnect event, establishes the connection, sets the TEntityConnection.Connected property to True, and generates an TEntityConnection.AfterConnect event. In addition, when calling Connect TEntityConnection may display a login dialog, depending on the value of TEntityConnection.LoginPrompt.
