There is no such equivalent in Firebird's SQL. But almost any
management tool knows how to extract metadata. Being just JDBC driver
JayBird does not provide such capabilities.

If you need metadata information for the whole database and do not
care if they are in text or as a transportable backup, you can always
exec gbak and pass switch to backup metadata information only.

Hope this helps.
