Re: [SQL] datetime query issue

um, this was probably unintelligible. this is the table:

+----------------------------------+----------------------------------+-------+
| Field | Type | Length|
+----------------------------------+----------------------------------+-------+
| source_numeric | int8 not null | 8 |
| destination_numeric | int8 not null | 8 |
| source | text not null | var |
| destination | text not null | var |
| bytes | int8 not null | 8 |
| date | datetime | 8 |
+----------------------------------+----------------------------------+-------+

every hour, a set of rows is added to this table with the current timestamp on
each row. i guess i need a function to extract the time from datetime. date_trunc
may be what i am looking for but i couldn't find information in the documentation
as to how to use these functions.
