Description​

Retrieve the range of elements in the sorted set and store it in destination.

Options​

  • BYSCORE - Sorts the elements in accending order of score before calculating the range.
  • BYLEX - Sorts the elements in ascending lexicographical order before calcularing the range. This option only works if all the members have the same score.
  • REV - Reverse the order determined by BYSCORE or BYLEX.
  • LIMIT - Offset determines where SugarDB will start counting from after the previous modification. Count is the number of elements to extract after the offset.
  • WITHSCORES - Whether the result should include scores.

Examples​

Get range by score and store it at the destination key:

db, err := sugardb.NewSugarDB()
if err != nil {
  log.Fatal(err)
}
cardinality, err := db.ZRangeStore(
  "destination", "source", "11.55", "15.66",
  db.ZRangeStoreOptions{
    ByScore:    true,
    Rev:        true,
    WithScores: true,
    Offset:     0,
    Count:      2,
})
