235db035ce Ok, i'm joining Firebird destruction team with my cleanup: 
1. Bring trace DSQL, DYN and BLR trace logging up-to-date
2. Remove redundant CSB pointer dereferences in BLR parser and request compiler
3. Convert RIGHT JOIN to LEFT JOIN early during BLR parsing
4. Check BLR syntax for unititalized contexts usage
5. Some type-safety and const-correctness fixes

df3c6abf15 1) fix: Unique index must be complete used else we keep on looking for another one. 
2) MERGE can also handle expressions, stupid example :
  SELECT
    *
  FROM
    RDB$RELATIONS r,
    RDB$RELATION_FIELDS rf
  WHERE
    rf.RDB$RELATION_NAME || 'A' = r.RDB$RELATION_NAME || 'A'
3) Do some code style issues

7e2b62528a bugfix: OUTER JOINs and no current record for fetch operation, caused by previous optimizer change 2002-12-28 00:20:45 +00:00
arnobrinkman
aa638632a3 another bugfix Alpha5 "no current record for fetch operation" 
Added code so that more index-retrieval can be used.
Cases where an LEFT OUTER JOIN messed-up the optimizer should be much lower.
Example :
SELECT * FROM
  SomeTable t1
  LEFT JOIN AnotherTable t2 ON (t1.PK_Key = t2.FK_Key)
  JOIN AnotherTable t3 ON (t1.PK_Key = t3.FK_Key)

This change fixed also BUG SF #219525.
