| Subj: |  | Re: optimiser query |  |  |  | From: |  | Kumaran Anantaraman |  
 I am currently facing same issue : 2 queries that are only different in the order of the table names in the FROM clause produce different
plans, in fact 1 has a product join of 1=1.  Subject to the explanation given above by Hough, is there a guideline on preferred order of
table?  Is it better to list small tables first, or good selectivity tables first?  I am also going to explore collect stats to help
optimizer break the tie. Thanks.
