How Would Go About Query Tuning?

Answer»
  • LOOK at the query plan
  • Look at the stats of the table/tables in the query
  • look at the table distribution keys and joins in the query
  • look at the NETWORK performance
  • look at the resource queues
  • look at the INTERCONNECT performance
  • look at the join ORDER of tables in the query
  • look at the the query itself i.e. if it can be written in more EFFICIENT way
