1e2edd445d Reworked the rsb/cursor logic a bit. Now I don't think sub-queries should be cursors. 2010-04-15 16:10:51 +00:00

90b128d6b6 Fixed CORE-2890: SQLSTATE should also be available as a PSQL context variable like GDSCODE/SQLCODE. 
To be later backported into v2.5.1, I suppose.

c737d6a807 Create ExprNode class hierarchy. 
Convert CONCATENATE and aggregate functions to it.

Fix some bugs:
- select sum(n) over (order by n2), sum(n) over (), n, n2 from x1;
- select (select 1 from x1 b where list(1, a.n) = 1) from x1 a;

11495a55fb Refactored the whole RSB stuff into classes. They're inside the /recsrc sub-directory now. 
Fixed the layering for WITH LOCK and (partially) ANY/ALL predicates.
Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).
Wiped out a lot of the pre-ODS11 optimizer logic. Some minor adjustments there.
Re-implemented the full outer join from scratch. This resolves CORE-2678 (full outer join cannot use available indices).
Resolved CORE-2796: DB_KEY is always zero for external tables.
Implemented the core part of the scrollable PSQL cursors. Implementation is still incomplete, but ready for testing.
Some other changes I don't recall at the moment ;-)

WARNING! The engine may be unstable. Please email me about any issues found.

ed0e0daeb3 - External Engines implementation. 
- 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.
