Info

Upgrading to ASE 15.0Possible SQL changes in existing applications• When using semantic partitions, this may impact schema and queries• Define a meaningful partition key• Queries should reference the partition key for best performance• Existing data may need to be partitioned (may take long for big tables)• The new query processing (hash joins etc) depends on proper use of 'optimizationgoals'• allrows_oltp, allrows_mix (default), allrow_dss• Important: pick the right goal server-wide (no change to existing SQL!)• When a particular session or query needs a different optimization goal (than server-wide)for best performance, small changes to existing SQL may be needed• Add set plan optgoal statementsSybase Symposium 2007 – November 15 - Brussels16
