# REVOKE READ ON SHARE

For restricted shares, use the `REVOKE` command to explicitly remove share access from users that have an existing `GRANT`.  After running a `REVOKE` command there may be a delay of a few minutes before access is fully removed if a user is currently querying the share.  Only the owner of the share can use the `REVOKE` command to remove access from others. `GRANT` and `REVOKE` do not apply to `UNRESTRICTED` shares.

## Syntax

```sql
REVOKE READ ON SHARE <share name> FROM <username> [, <username2>, <username3>];
```

If a username contains special characters, such as '@', it must be enclosed in double quotes (`"`).

## Example usage

```sql
-- revokes access to the share 'birds' from the user with username 'duck'
REVOKE READ ON SHARE birds FROM duck;

-- revokes access to the share 'taxis' from the users with usernames 'usr1' and 'usr2'
REVOKE READ ON SHARE taxis FROM usr1, usr2;

-- revokes access from a user whose username contains special characters
REVOKE READ ON SHARE sensitive_data FROM "user@example-com";
```
