ZRANGESTORE - Upstash Documentation

Use ZRANGESTORE to run the same selection as ZRANGE and store the result in another sorted set instead of returning it. The selection works exactly as it does for ZRANGE: by index, or by score with BYSCORE, or by member with BYLEX, with REV and LIMIT available in the same way. The members keep their original scores in the destination, which is overwritten if it exists and deleted when the range is empty. The reply is the number of members stored. This is how a slice of a large ranking is materialized once, for instance the top thousand of a leaderboard, so that further intersections or repeated paging run against a small key.

Syntax

ZRANGESTORE <dst> <src> <min> <max>
  [BYSCORE | BYLEX]
  [REV]
  [LIMIT <offset> <count>]

Arguments

Argument	Required	Repeatable	Description
`<dst>`	Yes	No	Redis key used as dst.
`<src>`	Yes	No	Redis key used as src.
`<min>`	Yes	No	Lower bound. Interpreted as a rank by default, as a score with `BYSCORE`, or lexicographically with `BYLEX`.
`<max>`	Yes	No	Upper bound. Interpreted as a rank by default, as a score with `BYSCORE`, or lexicographically with `BYLEX`.
`(BYSCORE \| BYLEX)`	No	No	How the two range arguments are read: `BYSCORE` as score bounds (inclusive, or exclusive with a `(` prefix, and `-inf`/`+inf` allowed), `BYLEX` as member bounds (`[member`, `(member`, `-`, or `+`), which only makes sense when every member has the same score. They are zero-based indexes when neither is given.
`REV`	No	No	Reverse the result order.
`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	Integer
RESP3	Integer

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.
