---|---|---|
MovePrevUnique()()() |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast()()(). Otherwise, move the cursor to the previous
non-duplicate key in the database, and store that key and associated
datum in Current. MovePrevUnique will return false if
no non-duplicate key/data pairs exist after the cursor position in
the database.
| |
MovePrevUnique(LockingInfo) |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast(LockingInfo). Otherwise, move the cursor to
the previous non-duplicate key in the database, and store that key
and associated datum in Current. MovePrevUnique will
return false if no non-duplicate key/data pairs exist after the
cursor position in the database.
| |
MovePrevUnique(DatabaseEntry, DatabaseEntry) |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast()()(). Otherwise, move the cursor to the previous
non-duplicate key in the database, and store that key and associated
datum in Current. MovePrevUnique will return false if
ntheo non-duplicate key/data pairs exist after the cursor position in
database. If either the key or the data is partial
DatabaseEntry, its
PartialLen bytes starting
PartialOffset bytes from the beginning
of the retrieved data record are returned as if they comprised the
entire record. If any or all of the specified bytes do not exist
in the record, MovePrevUnique is successful, and any existing
bytes are returned.

MovePrevUnique(DatabaseEntry, DatabaseEntry, LockingInfo) |
If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast(LockingInfo). Otherwise, move the cursor to
the previous non-duplicate key in the database, and store that key
and associated datum in Current. MovePrevUnique will
return false if no non-duplicate key/data pairs exist after the
cursor position in the database. If either the key or the data
is partial DatabaseEntry, its
PartialLen bytes starting
PartialOffset bytes from the beginning
of the retrieved data record are returned as if they comprised the
