Explanation:

In Snowflake, to create a materialized view, the user must have the necessary privileges on the schema where the view will be created. These privileges are granted through roles, not directly to individual users. Therefore, the correct process is to grant the role to the user and then grant the privilege to create the materialized view to the role itself.

The statementGRANT ROLE MYROLE TO USER USER1;grants the specified role to the user, allowing them to assume that role and exercise its privileges. The subsequent statementCREATE MATERIALIZED VIEW ON SCHEMA MYDB.MYSCHEMA TO MYROLE;grants the privilege to create a materialized view within the specified schema to the roleMYROLE. Any user who has been grantedMYROLEcan then create materialized views inMYDB.MYSCHEMA.
