Sorts and ranges
You can query the database
in more ways than one.
- If you want to put the entire database in
a particular order, you SORT the database by index points. Using
any index sorts the database. Not all fields in the database
are indexes.
- If you want to identify a subset of the
database by an indexed range of values such as date or a specific
field and its value, you SET A RANGE. These ranges are alternative
to each other; that is, you use one or the other, but cannot
use both, and using one cancels the other. Dates and fields
are indexes in the system, so using these to identify a group
of records is particularly efficient and quick for the system.
