Metadata System Tables

The metadata system tables provide information about the metadata of the database. The metadata system tables are placed in the system schema SYS.

The system schemas SYS and EXA_STATISTICS are automatically integrated into the namespace. This means that the tables in the system schemas can be accessed without specifying the schema as long as the same table name is not in use in the current schema.

The following table provides you with a list of all the metadata system tables in Exasol. Click the table name to view its details.
