LOCALTABLEATOMS System Table Description


A pseudo table, similar to GLOBALATOMS, except generated to show only atomThe internal object structure representing all data in a NuoDB database. Atoms are self-coordinating objects that represent specific types of information (such as data, indexes or schemas).s for tables, and only those atoms local to the TE to which the client is connected (See GLOBALATOMS System Table Description).

Caution: Client applications should never contain code that accesses SYSTEM pseudo tables as they are subject to, and furthermore likely to, change from release to release.


Like SYSTEM.GLOBALATOMS, most fields in LOCALTABLEATOMS are not of much interest to the user.
