0abfaa9840 Fix #2093 
Update after discussion with Monty
 2003-12-12 22:13:57 +04:00

e6e0937dc4 Proposed fix for #2093 
it happens because of the LEFT JOINT optimization in add_key_part()
This optimization does exactly the same in JOIN and in WHERE conditions 
Not right.
I moved that optimization one level upper.

3938ac5436 This ChangeSet Introdices Item_equal. 
The objects of this class represent multiple conjunctive equalities
in where conditions: =(f1,f2,...fn) <=> f1=f2 and f2= ... and =fn.
The objects are used to generate new possibale paths to access
the tables when executing a query.
They are also used to optimize the execution plan 
chosen by the optimizer for the query.
