◆ close()
| void gpudb::GPUdb::close | ( | ) |
Drops the SQL #name temp tables this object created, if any.
A session ID given by Options::setSessionId() is not dropped: the caller drops it with dropSession(). The destructor does the same, with a short timeout and no failover; closing first is what makes the drop reliable.
Exceptions
| GPUdbException | if the drop fails; it is not retried, and the server reclaims the tables on its own |
