2.3.37.17 Table::getLogging()

Description.  This class is used to check whether a table is logged to disk—that is, whether it is permanent or temporary.

Signature. 

bool getLogging
    (
      void
    ) const

Parameters.  None.

Return value.  Returns a Boolean value. If this method returns true, then full checkpointing and logging are done on the table. If false, then the table is a temporary table and is not logged to disk; in the event of a system restart the table still exists and retains its definition, but it will be empty. The default logging value is true.
