ZREVRANGEBYLEX - Upstash Documentation

Warning

Prefer ZRANGE with BYLEX and REV in new code: ZRANGE <key> <max> <min> BYLEX REV [LIMIT <offset> <count>].

Use ZREVRANGEBYLEX to list the members in a lexicographic range, in reverse order.

The bounds are given highest first, <max> before <min>, written [member for inclusive and (member for exclusive, with + and - for the extremes. LIMIT <offset> <count> pages through the result.

As with every lexicographic operation, the ordering is only meaningful when all members share the same score.

Syntax#

ZREVRANGEBYLEX <key> <max> <min> [LIMIT <offset> <count>]

Arguments#

Argument	Required	Repeatable	Description
`<key>`	Yes	No	Redis key targeted by the command.
`<max>`	Yes	No	Lexicographic maximum: `-`, `+`, `[member` (inclusive), or `(member` (exclusive).
`<min>`	Yes	No	Lexicographic minimum: `-`, `+`, `[member` (inclusive), or `(member` (exclusive).
`LIMIT <offset> <count>`	No	No	Skip `<offset>` matches and return at most `<count>`; a `<count>` of `-1` returns all remaining.

Response#

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

Protocol	Reply
RESP2	Array of bulk-string members
RESP3	Array of bulk-string members

Note

Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

Examples#

TCP examples use the TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
