Méthodes publiques

Méthode	Description
OleDbAccessDaLayer ( OleDbDescriptor connDesc ) : System	Construct the layer. Should typically be called only by the appropriate ConnectionDescriptor.
StoreRoomMissing ( ClassMapping mapping ) : bool	Returns true if you need to call "CreateStoreRoom" before storing any data. This method is "Missing" not "Exists" because implementations that do not use a store room can return "false" from this method without breaking either a user's app or the spirit of the method. Store room typically corresponds to "table".

Méthodes protégées

Méthode	Description
GetAsciiStringType ( ) : string	Returns the SQL type used to store an ascii string in the DB. MS Access does not seem to differentiate between encodings.
GetAutoType ( Type baseType ) : string	Returns the DDL for the type of an automatically incrementing column. Some databases only store autonums in one col type so baseType may be ignored.
GetByteArrayType ( ) : string	Returns the SQL type used to store a byte array in the DB.
GetDateTimeType ( ) : string	Returns the SQL type used to store a DateTime in the DB.
GetLongType ( ) : string	Returns the SQL type used to store a long in the DB.
GetStringType ( ) : string	Returns the SQL type used to store a "normal" (unicode) string in the DB.

StoreRoomMissing() public méthode

Returns true if you need to call "CreateStoreRoom" before storing any data. This method is "Missing" not "Exists" because implementations that do not use a store room can return "false" from this method without breaking either a user's app or the spirit of the method. Store room typically corresponds to "table".
