Description

Turned ID <> 1, ID <> 2, ... into ID IN (1, 2, ...).
Removed some redundant ->prepare as the IDs are already int-cast, hence improved performance.

Concatenation is done once also, not once for each excluded ID.
Shortened the query a lot and gained 20% in speed compared to old method (on about 25 excluded pages from about 40).

  • Keywords has-patch 3.4-early added
  • Milestone changed from Awaiting Review to Future Release
  • Type changed from task (blessed) to enhancement

Looks good. We probably have a few other areas in core that results in similar SQL construction as well.
