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.

6d64014e57 Changed engine to store source file name/line number information for EVERY allocation when DEBUG_GDS_ALLOC is defined. All allocation should be done using FB_NEW or FB_NEW_RPT macros instead of keyword new since now 2002-09-25 17:12:16 +00:00

95281ccf25 1. New system variables - CONNECTION_ID and TRANSACTION_ID
2. Universal triggers
(parser changes are not very nice, but at least it works;
perhaps it should be polished up a bit later)
