# Extracting Metadata From a Secondary Database

The [sdb-admin dump](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-admin-commands/dump.md) command should be used to extract metadata consisting of DDL and objects definitions from a secondary database.

> **📝 Note**: SingleStore does not recommend using the `mysqldump` command for this operation.
