> [!NOTE]
> This command's behavior varies in clustered Redis environments. See the [multi-key operations](https://redis.io/docs/latest/develop/using-commands/multi-key-operations) page for more information.


This command is equal to [`SINTER`](https://redis.io/docs/latest/commands/sinter), but instead of returning the resulting set,
it is stored in `destination`.

If `destination` already exists, it is overwritten.

## Required arguments

<details open><summary><code>destination</code></summary>

The key to store the resulting set in.

</details>

<details open><summary><code>key [key ...]</code></summary>

One or more set keys to intersect.

</details>

## Examples


redis> SADD key1 "a"
(integer) 1
redis> SADD key1 "b"
(integer) 1
redis> SADD key1 "c"
(integer) 1
redis> SADD key2 "c"
(integer) 1
redis> SADD key2 "d"
(integer) 1
redis> SADD key2 "e"
(integer) 1
redis> SINTERSTORE key key1 key2
(integer) 1
redis> SMEMBERS key
1) "c"
