outside the scope of the cursor loop was accepted by the PSQL parser, allowing the likelihood of run-time occurring as a result. Now, it will be rejected in the procedure or trigger definition. NULLS are STRING_ARGUMENT, index scanning is allowed because the conversion is deterministic. (V.2.1) Some date/time expressions in Dialect 1 can not benefit from available indices either, e.g., DATE_ FIELD > 'NOW' ISC_LONG*, short, const ISC_SCHAR*, ISC_EVENT_CALLBACK, void*); It may cause a compile-time incompatibility, as older event handling programs cannot be compiled if they use a bit different signature

you use the SEQUENCE syntax in new code. Although the word “sequence” puts the emphasis on the series of values generated whereas “generator” seems to refer primarily to the factory that produces these written to, it would overwrite data. This could sometimes lead to an immediate error, but most of the time it would just silently corrupt your database. 2.6. Generators and transactions As said, generators “rollback” generators inside a transaction. There may be other transactions executing at the same time that change the value while your transaction runs. So once you have requested a generator value,

server and an In- terBase server on the same machine with these versions - at least not at the same time. This restric- tion has been removed in Firebird 1.5. Table 2. Components of the Firebird 1.0 installation structured WinZip .zip file – it is strongly recommended that you use the distributed release kit the first time you install Firebird. The Windows executable installa- tion script, the Linux rpm (RPM Package Manager Windows NT, 2000 and XP – the Firebird service will be running when the in- stallation completes. Next time you boot up your server machine, it will be started automatically. The non-server Windows platforms
