C# Класс Azavea.Open.DAO.OleDb.OleDbAccessDaLayer

Implements a FastDao layer customized for PostGreSQL (optionally with PostGIS installed).

Наследование: Azavea.Open.DAO.SQL.SqlDaDdlLayer

Открытые методы

Метод	Описание
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".

Защищенные методы

Метод	Описание
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.

Описание методов

GetAsciiStringType() защищенный Метод

Returns the SQL type used to store an ascii string in the DB. MS Access does not seem to differentiate between encodings.

protected GetAsciiStringType ( ) : string
Результат	string

GetAutoType() защищенный Метод

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.

protected GetAutoType ( Type baseType ) : string
baseType	System.Type	The data type of the column (nominally).
Результат	string

GetByteArrayType() защищенный Метод

Returns the SQL type used to store a byte array in the DB.

protected GetByteArrayType ( ) : string
Результат	string

GetDateTimeType() защищенный Метод

Returns the SQL type used to store a DateTime in the DB.

protected GetDateTimeType ( ) : string
Результат	string

GetLongType() защищенный Метод

protected GetLongType ( ) : string
Результат	string

GetStringType() защищенный Метод

Returns the SQL type used to store a "normal" (unicode) string in the DB.

protected GetStringType ( ) : string

OleDbAccessDaLayer() публичный Метод

Construct the layer. Should typically be called only by the appropriate ConnectionDescriptor.

public OleDbAccessDaLayer ( OleDbDescriptor connDesc ) : System
connDesc	OleDbDescriptor	Connection to the Firebird DB we'll be using.
Результат	System

StoreRoomMissing() публичный Метод

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".

public StoreRoomMissing ( ClassMapping mapping ) : bool
mapping	ClassMapping
Результат	bool
