공개 메소드들

메소드	설명
FirebirdDaLayer ( FirebirdDescriptor 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". Firebird doesn't appear to support the SQL standard information_schema.

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.
GetBooleanType ( ) : string	Returns the SQL type used to store a boolean in the DB.
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. NOTE: At the moment just uses varchar, so will rely on whatever the DB is using for an encoding.
