Public Methods

Method Description
OleDbOracleDaLayer ( OleDbDescriptor connDesc ) : System

Construct the layer. Should typically be called only by the appropriate ConnectionDescriptor.
SequenceExists ( string name ) : bool

Returns whether a sequence with this name exists or not. Firebird doesn't appear to support the SQL standard information_schema.
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".

Protected Methods

Method Description
GetAsciiStringType ( ) : string

Oracle doesn't seem to have a varchar type that is limited to ASCII characters.
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.
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.
