[GENERAL] How to return an Int4 when subtracting dates/timestamps

[Andre Lopes]

Hi,

I need to return an Int4 when I do this king of select

[code]
select CURRENT_DATE - '2009-12-31' from tbl_sometable
[/code]

This select returns an Interval. How can I return an Integer? Like '138'


Sorry my bad english.

Best Regards,
