Méthodes publiques

Méthode	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".

Méthodes protégées

Méthode	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.

Method Details

GetAsciiStringType() protected méthode

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

protected GetAsciiStringType ( ) : string
Résultat	string

GetAutoType() protected méthode

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).
Résultat	string

GetByteArrayType() protected méthode

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

protected GetByteArrayType ( ) : string
Résultat	string

GetLongType() protected méthode

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

protected GetLongType ( ) : string
Résultat	string

GetStringType() protected méthode

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

protected GetStringType ( ) : string
Résultat	string

OleDbOracleDaLayer() public méthode

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

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

SequenceExists() public méthode

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

public SequenceExists ( string name ) : bool
name	string	Name of the sequence to check for.
Résultat	bool

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".

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