I am a beginner at SQL and would appreciate any help with a simple query.
I have two tables: host patch The host table contains details for a particular host (OS, cpus, memory, etc) and the patch table contains patches installed on that host. For example: Host: hostid hostname OS cpus memory 8000abcd abacus 2.6 4 1024 8001abce quark 2.8 1 512 8008efd1 sharp 2.9 2 2048 Patch: hostid patchnumber patchversion 8000abcd 105181 31 8000abcd 109201 01 8000abcd 108701 15 8001abce 108528 12 8001abce 108655 10 8001abce 106655 07 . . . I am trying to write a query that would list all hosts that do not have a particular patch installed.
