Public Methods

Method	Description
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.

Protected Methods

Method	Description
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.

Method Details

FirebirdDaLayer() public method

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

public FirebirdDaLayer ( FirebirdDescriptor connDesc ) : System
connDesc	FirebirdDescriptor	Connection to the Firebird DB we'll be using.
return	System

GetAutoType() protected method

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).
return	string

GetBooleanType() protected method

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

protected GetBooleanType ( ) : string
return	string

GetByteArrayType() protected method

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

protected GetByteArrayType ( ) : string
return	string

GetDateTimeType() protected method

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

protected GetDateTimeType ( ) : string
return	string

GetLongType() protected method

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

protected GetLongType ( ) : string
return	string

GetStringType() protected method

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.

protected GetStringType ( ) : string
return	string

SequenceExists() public method

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.
return	bool

StoreRoomMissing() public method

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.

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