217773ac42 1) Field with alias was also seraching for match in higher context then the first matching context found. Noted by Nickolay 
Example (this does fail now with column o.ID unknown):
SELECT * FROM Orders o
WHERE
  EXISTS(SELECT * FROM RDB$DATABASE o WHERE o.ID = 1)
2) Improved derived table support.
  When using derived tables inside sub-selects it should be able to reference to higher contexts.

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.

  SELECT

  FROM

536d8c0552 1. Reworked internal_info implementation in both DSQL and JRD. 
New helper class created to serve it properly.
2. Added exception re-raise semantics.
Syntax: EXCEPTION;
If there was handled exception, re-initiate it, otherwise evaluate to no-op.
3. Implemented run-time exception messages.
Syntax: EXCEPTION <exception_name> [<value>];
If <value> is specified, evaluate it and use instead of RDB$EXCEPTION_MESSAGE.
4. Added new SQLCODE and GDSCODE system variables.
Available in procedures/triggers only.
If there wasn't any exception raised, return zero (success), otherwise return an error code.
5. Implemented ROWS_AFFECTED system variable.
Available in procedures/triggers only.
Count rows affected by the last INSERT/UPDATE/DELETE statement.
For any other statement, result is always zero.

d757d31ed4 Added code in pass1_simple_case for handeling parameters in case_operand together with when_operands. 
The method used to get the derciber for parameters is taken from MAKE_desc_from_list in make.cpp
Example : SELECT CASE FieldA WHEN :param1 THEN 1 WHEN 2 THEN 2 ELSE NULL END FROM TableA
Note : At least one "know describer" must be in the list else no describer could be guested (logic but...) !

7922269845 1. BIGINT is now the only keyword for the 64-bit exact numerics and it's available 
in dialect 3 only.
2. BREAK statement has been disabled in triggers (like EXIT) because of the known
   BLR limitations. I hope it can be safely used in stored procedures though, hence
   I'd prefer to have it officially documented.
3. More complete implementation of the GROUP BY clause. You can group by internal
   functions and have ability to use more complex grouping conditions than before.
   By Arno Brinkman.
4. Allowed declaring and defining local variables at the same time.
   By Claudio Valderrama.
   Syntax: declare [variable] <var_name> <var_type> [{= | default} <default_value>]
5. Allowed ordinals to be used in the GROUP BY clause (like ORDER BY).
   By Arno Brinkman.
   Example: select extract(month from order_date), sum(order_sum) from orders group by 1
6. The first approach to the ALTER VIEW statement. Only high-level implementation so far.
   A lot of work in dfw.epp, metd.epp, etc. still required.
   By Dmitry Yemanov.
