you only need a quick reference to refresh your memory, go to the summary at the end of the guide. So — what is it? In SQL, NULL is not a value. It is a state indicating that an item’s value is unknown sense it’s not really wrong — it just doesn’t give you what you want. The same goes for “… <> NULL”, so don’t use that either; use IS NOT NULL instead. IS NULL and IS NOT NULL always return true or false; You can e.g. include NULL in an IN() list, write expressions like “if ( MyField = NULL ) then…”, and so on. However, as a general rule you should not make use of these new possibilities! In almost every

You may distribute such modified versions, but if you do so, you must document your modifications and make them publicly available, at no cost, under the same them, from ODS 13.0 to ODS 13.1, but won’t open databases that were created by Firebird 3 or older. So, before taking down your existing setup, you should back up all your databases in order that you can to upgrade from ODS 13.0 to ODS 13.1, but we recommend using the backup and restore route (if only so you have a backup as a fallback). Upgrading the security database from Firebird 2.5 and earlier Back

this variable, you should remove or update it before you begin installing Firebird 2.1. After doing so, you should also check that the old value is no longer Known Compatibility Issues 2 visible in the but it did not. In Firebird 2.0, if you need to make NULL invalid in a CHECK constraint, you must do so explicitly by extending the constraint. Using the example above: CHECK (DEPTNO IN (10, 20, 30) AND purpose is to allow a window for people to bring legacy code into line. It will be deprecated in future so there is no good reason for anyone to write non-compliant statements in new code! Multiple Hits to

page (page type 0x01 — see below) which holds details about the database itself, the page size and so on. The second page in the database is a Page Inventory Page or PIP (page type 0x02) which details Pointer Pages (page type 0x04), Index BTree Pages (page type 0x07), Data Pages (page type 0x05) and so on. There is a discussion of each page type below. 2.2. Multiple File Databases A multiple file Firebird database, where its other files are to be found, shadow file names, database page size, ODS version and so on. On startup, the Firebird engine reads the first part (1,024 bytes) of the first page in the first

identifier such as "FULLNAME" is the same as the regular identifiers FULLNAME, fullname, FullName, and so on. The reason is that Firebird stores regular identifiers in upper case, regardless of how they were before being inserted into the table. However, this happens after the numerical value is determined, so 0x80000000 (8 digits) and 0x080000000 (9 digits) will be saved as different BIGINT values. 3.2. Floating-Point internally to DECFLOAT(34). The result of various mathematical operations, such as LOG(), EXP() and so on, and aggregate functions using a high precision numeric argument, will be DECFLOAT(34). 3.3.1
