11b4fcf5b7 1) Make COALESCE/CASE output descriptor more SQL-standard. 
Exception is that we allow mixing datatypes with (var)char (except blob), because all datatypes are convertable to character-type and because this functionallity was available from 1st day COALESCE is introduced inside Firebird.
2) Fix bug with expressions without fields inside aggregate-functions.
Example :
  SELECT
    (SELECT Count(1) FROM RDB$DATABASE)
  FROM
    RDB$RELATIONS

Only a lower context is possible with nested aggregates.

c1c723103f Disallowed explicit locking for aggregate queries. 
The same should be done for stored procedure streams (joins require some work too).

192ba388d4 1) bugfix RC1: Aggregates from a different parent_context where not allowed in the HAVING clause. 
2) Enabled aggregate-functions from different parent_context (with lower scope_level) to be used inside another aggregate-function

42ef1314ec DSQL warning fixes. 2003-04-08 00:31:20 +00:00
dimitr
be5247dc1c 1. Cleanup 
2. ROWS_AFFECTED is renamed to ROW_COUNT
(see SQL2002 specification)
3. CONNECTION_ID/TRANSACTION_ID are renamed to CURRENT_CONNECTION/CURRENT_TRANSACTION
(see SQL2002 recommendations for context functions)
4. Solved most of the shift/reduce conflicts and all reduce/reduce conflicts in the grammar
5. Fixed ambiguity in ORDER BY clause, when both the value and the clause itself could contain COLLATE word
(now explicit collation sequence of the value is used in the ordering logic)
6. Some of newly introduced tokens are made non-reserved
7. Added code to enable ORDER/GROUP BY ordinal when asterisk is used in the select list
(not sure which version it should go, so it's commented out so far)
