You can use the SELECT statement to access virtual tables that contain metadata information. These virtual tables reside in a virtual schema named ADMIN_SCHEMA. The ADMIN_SCHEMA schema resides in the metadata database in the Data Vault.
Use the following syntax to access a virtual table:
SELECT * from ADMIN_SCHEMA.<table name>
Example:
SELECT * from ADMIN_SCHEMA.TABLES
You can access the following virtual tables:
ADMIN_SCHEMA.TABLES
ADMIN_SCHEMA.PARTITIONS
ADMIN_SCHEMA.COLUMNS
ADMIN_SCHEMA.DOMAINS
ADMIN_SCHEMA.PART_LIMITS
ADMIN_SCHEMA.TAB_LIMITS
ADMIN_SCHEMA.HOSTS
ADMIN_SCHEMA.AGENTS
ADMIN_SCHEMA.TASKS
ADMIN_SCHEMA.CLIENTS
ADMIN_SCHEMA.SESSIONS
ADMIN_SCHEMA.USERS
ADMIN_SCHEMA.DATABASES
ADMIN_SCHEMA.ADMINS
ADMIN_SCHEMA.VERSIONS
