SETCOMPDATE

ISODRAFT Reference Manual

Command Reference Section : Alphabetical Command Reference : SETCOMPDATE

Sets the Comparison Date for an MDB or DB.

Sets the Comparison Date for an MDB or DB. The user can set the comparison date to an actual date, to a stamp, or, for a specific DB, to an exact session number and/or extract number. The comparison date can be used in queries and, for example, in Change Highlighting, where it is necessary to specify a comparison date in order to determine which elements have been changed since the specified date.

Note:

If a stamp is used to set the comparison date, this will set the comparison session for each database within the stamp. It will also reset any comparison dates set previously.

Querying a date will only return a value if the last SETCOMPDATE command used a date on its own, otherwise it will return 'unset'. Similarly, querying a stamp is only valid if the last SETCOMPDATE command used a stamp.

Examples:

SETCOMPDATE 10 January 2002

Sets the comparison date to 10 January 2002.

SETCOMPDATE STAMP stamp 016

Sets the comparison date to stamp 016.
