The correct SQL command for removing a schema in Snowflake is:

DROP SCHEMA temp_schema;

This command deletes the schema and all objects contained within it, including tables, views, stages, file formats, and sequences. Snowflake performs this operation atomically, ensuring metadata consistency during the drop process. Users can also includeIF EXISTSor theCASCADEkeyword to handle dependencies more explicitly:

DROP SCHEMA IF EXISTS temp_schema CASCADE;

This safely handles scenarios where the schema may not exist or contains objects that would normally block deletion.

Incorrect options:

DROP DATABASE temp_schemaremoves an entire database, not a schema.

DELETE SCHEMAis not valid SQL; SQL uses DROP for schema removal.

DROP VIEW temp_schemaapplies only to removing a view object.

Dropping a schema requires USAGE and OWNERSHIP privileges, typically granted to roles such as SYSADMIN or ACCOUNTADMIN.
