some tips for minimizing tempdb utilization

  1. use fewer #temp tables and @table variables.
  2. minimize concurrent index maintenance, and avoid the SORT_IN_TEMPDB option if it isn’t needed.
  3. avoid unnecessary cursors; avoid static cursors if you think this may be a bottleneck, since static cursors use work tables in tempdb.
