 **[1]:** In some SQL databases, the database name to be used is called "schema name". In case there are multiple layers that could be considered for database name (e.g. Oracle instance name and schema name), the database name to be used is the more specific layer (e.g. Oracle schema name).

If the SQL statement has an ambiguous operation, or performs more than one operation, this value may be omitted.
