a sequence. They are just two words for the same database object. You can create a generator and access it using the sequence syntax, and vice versa. This is the preferred syntax for creating a generator/sequence stored in special reserved pages inside the database. You never touch those values directly; you access them by means of built-in functions and statements which will be discussed later on in this guide initial information): Version Page size 1K 2K 4K 8K InterBase < v.6 247 503 1015 2039 IB 6 and early pre-1.0 Firebird 123 251 507 1019 All later Firebird versions 32767 In InterBase versions prior

Connecting to the sample database In the examples subdirectory of may fail if a user created the database in Classic local mode and the server doesn't have enough access rights. Note Although single quote symbols are the “norm” for delimiting strings in Firebird, double file is attempted with your Linux login as the owner. This may or may not be what you want (think of access rights if you want others to be able to connect). If you pre- pend localhost: to the path, the server

This loophole has been closed, a change that could affect several existing login is not supplied. • Embedded access without login/password works fine. On Windows, authentication is bypassed.

As far as other database access components are concerned, we're not sure if there are any issues (let alone how to solve them). server switching. However, because development of the Toggler started when Firebird 1.5 was in the early RC phase, certain RC characteristics that have since disappeared are still supported by it. These

ISC_USER=sysdba C:\> set ISC_PASSWORD=masterkey  This is very insecure as it allows anyone who can access your session the ability to perform DBA functions that you might not want to allow. -role role the SYSDBA decides to check the database.  Database validation requires that you have exclusive access to the database. To prevent other users from accessing the database while you validate it, use the server is never shutdown tidily.  If your database was originally created with Interbase 6 or an early beta version of Firebird, then the database will be running in asynchronous mode — which is not

an empty string — at least if you declare the function in the right way. 13.2.

It has been written in response to frequent questions on

data storage structures, referential integrity mechanisms, to data manipulation capabilities and access privileges. Firebird also implements a robust procedural language — procedural SQL (PSQL) — for deci-milliseconds precision. Deci-milliseconds precision is rare and is not supported by all drivers and access components. The best assumption to make from all this is that, although Firebird stores TIME and there as the argument for Restrict. If the file does not exist yet, Firebird will create it on first access.  The ability to use external files for a table depends on the value set for the ExternalFileAccess

perform a local (embedded or XNET) backup of the security database; embedded mode requires filesystem access rights to the database file; XNET (Windows only) requires username and password. 2. (only after databases) Install Firebird 5 (see later sections) 3. Note down the permissions, ownership and filesystem access rights of security5.fdb 4. Rename the existing security5.fdb for safekeeping 5. Restore the backup would require the security database to exist, and it would lock the file). 6. Change filesystem access rights/permissions to match the original security5.fdb For a Firebird 4 security database, it is

filesystem-level access rights to the database for this to work. On Linux, all local connections are made via the network layer, using localhost (often implicitly). Only the server process needs access rights to architectures now support safe and reliable local connec- tions, with only the server process requiring access rights to the database file. Multiprocessor SMP (symmetrical multi-processor) sup- port. Better creation of many different user accounts. Each of them can own databases and also have various types of access to databases and database objects it doesn't own. Using gsec, you can add a user account as follows
