- Plugins API.
- Feature CORE-2700 - UDR (User Defined Routines) Engine - C++ API supporting functions, triggers and stored procedures.
- Feature CORE-2470 - Support for alternate format of strings literals.
- Feature CORE-2310 - DDL triggers.
- Feature CORE-2312 - PSQL Packages.
- Feature CORE-1209 - CONTINUE statement.
- Feature CORE-1180 - DDL syntax to change (not) nullable state of columns.
- Feature CORE-2090 - Support OVER () clause with current aggregate functions.
- Fixed CORE-2699 - Common table expression context could be used with parameters.
- Introduce ODS 12.0.
- Work in progress in type-safe parser.
- Refactor some DDL commands (procedures and triggers) from DYN to DdlNodes.
- Refactor virtual tables to use a class hierarchy instead of namespaces. This is basic thing, not based on the changes done in Vulcan. Window functions is based on this work.
- Refactor COMMENT ON and DROP FUNCTION from DYN to DdlNodes. COMMENT ON do not use GDML anymore, it uses DSQL with PreparedStatement class.
- Refactor EXECUTE BLOCK to StmtNodes.
- Refactor the IUDF to SysFunctions. That eliminates RDB$GET_CONTEXT and RDB$SET_CONTEXT from RDB$FUNCTIONS.
function signatures
variables in local scope
BOOLEAN -> bool
TEXT[32] as SqlIdentifier for DYN
Stop random garbage in firebird.msg's bytes 8 to 11
some cleanup
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.
