LIMIT statement allows slicing the result array using an
offset and a count. It reduces the number of elements in the result to at most
the specified number.
Two general forms of
LIMIT count LIMIT offset, count
The first form allows specifying only the count value whereas the second form allows specifying both offset and count. The first form is identical using the second form with an offset value of 0.
FOR u IN users LIMIT 5 RETURN u
Above query returns the first five documents of the users collection.
It could also be written as
LIMIT 0, 5 for the same result.
Which documents it actually returns is rather arbitrary, because no explicit
sorting order is specified however. Therefore, a limit should be usually
accompanied by a
The offset value specifies how many elements from the result shall be skipped. It must be 0 or greater. The count value specifies how many elements should be at most included in the result.
FOR u IN users SORT u.firstName, u.lastName, u.id DESC LIMIT 2, 5 RETURN u
In above example, the documents of users are sorted, the first two results get skipped and it returns the next five user documents.
Variables, expressions and subqueries can not be used for offset and count. The values for offset and count must be known at query compile time, which means that you can only use number literals, bind parameters or expressions that can be resolved at query compile time.
LIMIT is used in relation to other operations in a query has meaning.
LIMIT operations before
FILTERs in particular can change the result
significantly, because the operations are executed in the order in which they
are written in the query. See FILTER
for a detailed example.
