Range query (database)
A range query is a common database operation that retrieves all records where some value is between an upper and lower boundary.[1] For example, list all employees with 3 to 5 years' experience. Range queries are unusual because it is not generally known in advance how many entries a range query will return, or if it will return any at all. Many other queries, such as the top ten most senior employees, or the newest employee, can be done more efficiently because there is an upper bound to the number of results they will return. A query that returns exactly one result is sometimes called a singleton.

gollark: The only message on 19 December is> 6K+ already?!?which seems pretty innocuous, so I'm assuming you're talking about the 20 December one about the (not implemented yet) restricted thing channels and will chalk this down to... time zones, or something.I'd kind of expect you to have said something in the intervening four months if this was a problem for you.
gollark: I mean, you're incoherently rambling about some rights violation and facism, so eh.
gollark: See, you're talking about it as if something happened *recently*, and whatever that is is 4 months ago.
