Greetings, Oh Massed Experience and Intellect! Which costs more, select from media or select from volumes? Or are they similar enough to flip a coin? I am trying to write a script in which I need to know which storage pool a given tape belongs to. Looking at the list of columns, it looks like I can select stgpool_name from volumes where volume_name='$volume_name' or select stgpool_name from media where volume_name='$volume_name' When I run both commands alone, select from media seems to return a quarter second faster, but that is pretty skimpy evidence.... timex says it depends on cached data.... I'll use select from media unless there is a better way. Platform is ADSM 3.1.2.20 on AIX 4.? TIA, Kai.
