Subject [jira] Commented: (DERBY-855) Document optimizer overrides which were introduced in 10.2
Date Mon, 30 Jan 2006 06:23:35 GMT
    [ http://issues.apache.org/jira/browse/DERBY-855?page=comments#action_12364436 ] 

Mamta A. Satoor commented on DERBY-855:
---------------------------------------

Couple comments
1)ctunoptimzoverride.html does a good job of cautioning the users to be careful about the
correct syntax when using the -- DERBY-PROPERTIES clause. It will be good to point the users
at this time to ctundepthoptover.html where they can verfiy if their overrides were correctly
identified by the parser or not.
2)There shouldn't be any space between nested and loop when given as a value to joinStrategy.
3)The Tuning Guide has sections "Working with RunTimeStatistics"->"Analyzing the infromation".
Under "Analyzing the information" page, can you add optimizer overrides to the existing list
of Statistics timing, statement execution plan and optimizer estimates?
