<use_schema_command> ::= USE SCHEMA <schema_name>
<schema_name> ::= <identifier>
Name of the schema that the database user is to use
If the name of the schema is identical to a keyword or if the upper- and lowercase notation is relevant, the name must be placed in double quotation marks.
USE SCHEMA hotel

You can use the USE SCHEMA command to specify which schema the current database user is to use. This setting applies as long as no other schema is specified using a USE SCHEMA, USE USER or SET CURRENT SCHEMA command.
