dudas con interbase

[cahp]

Hola:

SELECT current_time FROM RDB$Database

SELECT current_date FROM RDB$Database

SELECT current_timestamp FROM RDB$Database

esto es en Interbase 6.x

Creo que en versiones anteriores es:

SELECT cast('TODAY' as date) FROM RDB$Database
SELECT cast('now' as date) FROM RDB$Database


Saludos.
