USE SCHEMA¶
Specifies the active/current schema for the session.
If a database and schema, also known as a namespace, are not specified for a user session, all objects reference in SQL statements
or queries executed in the system must be fully-qualified (in the form of db_name.schema_name.object_name
). Specifying a
database and schema for a user session enables using unqualified object names in SQL statements and queries.
For more information about fully-qualified object names, see Object Name Resolution.

Syntax¶
USE [ SCHEMA ] [<db_name>.]<name>
Parameters¶
name
Specifies the identifier for the schema to use for the session. If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.
If
name
is not fully-qualified (withdb_name
), the command looks for the schema in the current database for the session.
Usage Notes¶
The
SCHEMA
keyword is optional if a database has been specified for the session or the schema name is fully-qualified.
Examples¶
Use the myschema
schema in the current database:
USE myschema;
Use the otherschema
schema in the otherdb
database:
USE otherdb.otherschema;
