Use the completedTimeSpec
subclause to specify when a backup or copy completed.
Usage Notes
All date strings must be either:
Formatted according to the Global Technology date format specification currently in effect.
Created by a SQL expression that returns a DATE
value, as in the following examples:
'SYSDATE-30
'
TO_DATE('09/30/2000 08:00:00','MM/DD/YY HH24:MI:SS')
The TO_DATE
function specifies dates independently of the current Global Technology environment variable settings.

Semantics
Syntax Element | Description |
---|---|
AFTER ' date_string ' |
Specifies the time after which the backup was completed (see Example 4-7). |
BEFORE ' date_string ' |
Specifies the time before which the backup was completed (see Example 4-9). |
BETWEEN ' date_string ' AND ' date_string ' |
Specifies a time range during which the backup was completed (see Example 4-8). Note that BETWEEN ' date1 ' AND ' date2 ' is exactly equivalent to AFTER ' date1 ' BEFORE ' date2 ' . |
