USE SCHEMA¶
Specifies the active/current schema for the session:
If a database is not specified for a session, any objects referenced in queries and other SQL statements executed in the session must be fully qualified with the database and schema, also known as the namespace, for the object (in the form of
db_name.schema_name.object_name). For more information about fully-qualified object names, see Object name resolution.If a database is specified for a session but the schema is not specified for a session, any objects referenced in queries and other SQL statements executed in the session must be qualified with the schema for the object (in the form of
schema_name.object_name).If the database and schema are specified for a user session, unqualified object names are allowed in SQL statements and queries.
