The `filter` can be any expression resulting in a [UInt8](../../sql-reference/data-types/int-uint.md)-type value. It usually contains comparisons and logical operators. Rows from `database_name.table1` where filter results to 0 are not returned for this user. The filtering is incompatible with `PREWHERE` operations and disables `WHERE→PREWHERE` optimization.
## Roles
You can create any predefined roles using the `roles` section of the `user.xml` configuration file.
Structure of the `roles` section:
```xml
<roles>
<test_role>
<grants>
<query>GRANT SHOW ON *.*</query>
<query>REVOKE SHOW ON system.*</query>
<query>GRANT CREATE ON *.* WITH GRANT OPTION</query>
</grants>
</test_role>
</roles>
```
These roles can also be granted to users from the `users` section:
```xml
<users>
<user_name>
...
<grants>
<query>GRANT test_role</query>
</grants>
</user_name>
<users>
```
