It can be created in a connected database, either by using the menu item Database / New Table, the respective icon in the New Database Object toolbar, or using the DB Explorer right-click menu (or key combination [Ctrl + N]), when the table heading of

It also follows that you can’t connect to a database if CONNECT trigger causes an exception, and that you can’t start a transaction if a TRANSACTION START trigger does so. Both phenomena effectively lock you out of your database while you need to get in there to fix the problem. See the note below for a way around this Catch-22 situation. The „After database connected“ event block processes a new output parameter DBEExtraCaption which may be used to replace default SQL dialect information followed by database alias in the Database Explorer.

Welcome to the IBExpert learning center, where we provide a range of tutorial films about Firebird and IBExpert. You can also find all these films at Databases can also be repaired or reduced in size by performing a backup and restore. If a database needs to be ported to another platform (e.g. from a Windows server to a Linux server), it is not the database file that is ported but the backup. This is then imported to the destination server by performing a restore of the backup file.

Import strings: allows a message list to be loaded from a text file. When you change interface language in Options / Environment Options, IBExpert replaces IBExpert.lng with another one and all your changes will be lost. Alternative language files are stored in Search in metadata << Import data | IBExpert | Extract Metadata >> The Search in Metadata option can be found in the IBExpert Tools menu, using the respective icon in the Tools toolbar, or started using the key combination [Shift + Alt + F]. It is identical to the Edit menu’s Find option – Find in Metadata page.

Databases can also be repaired or reduced in size by performing a backup and restore. If a database needs to be ported to another platform (e.g. from a Windows server to a Linux server), it is not the database file that is ported but the backup. This is then imported to the destination server by performing a restore of the backup file. Then the fixed length field will be a positive advantage. This efficient storage in Firebird can lead to considerable confusion particularly when importing data, as Paradox or dBase databases save all blank spaces, and after importing a 10MB dBase file into InterBase, often only 3-6 MB remain, although all data sets were imported correctly. The ALTER TRIGGER syntax (see above) has been extended to support database triggers. For a full discussion of this feature, see CREATE TRIGGER :: Database triggers.

This item is unfortunately not available in the free IBExpert Personal Edition. The Extract Metadata module can be used to generate a partial or full database metadata script, including table data, privileges and object descriptions if wished. It allows the If a character set is defined as the default character set when creating the database (and since Firebird 2.5 also the default collation), it is not necessary to define this again for individual columns. Firebird/InterBase ® supports more than 20 different character sets directly. The chosen character set is also of importance when importing and exporting data with different character

For a full discussion of this feature, see CREATE TRIGGER :: Database triggers. The Database Statistics are useful for detecting and solving a variety of performance problems, for example, revealing whether an old transaction is still open somewhere, which could be slowing the database down due to the administration of a constantly growing number of record versions.

Script Explorer The Script Explorer (the left-hand panel) displays all database objects, as well as IBEBlocks and Firebird blocks, used in the current script in a tree structure.

A cut out and keep guide to the Firebird source code By Ann Harrison and Paul Beach. This document is a rough guide to the Firebird code tree. Parts of that code tree build the Firebird Server, parts build utilities, and parts provide additional elements of the Firebird kit, and a certain number of parts don’t contribute anything, being specific to environments that no longer exist.

Adding primary keys to existing tables This article was written by Melvin Cox, and provides a method of defining primary keys on existing tables using IBExpert: Here is a viable workaround for those of us who do not wish to spend an eternity exporting data, dropping and recreating multiple tables, and finally import the data back into those tables. Firebird administration using IBExpert Administration tasks Downloading and installing the various Firebird versions Automating the database backup and restore Garbage collection Setting up protocols Administrating users Setting up and testing the ODBC driver Importing and exporting data Transferring data to a new table or another database Optimizing the database Split complex tables into several smaller ones (Database normalization). For reasons of compatibility with legacy databases, it might help to add an updatable view with the name of the old table and with the same structure.

The Firebird database content is transmitted via ODBC into these databases and then synchronized. In general, this replication can be implemented with any ODBC-compliant database to synchronize, for example, the data in a MySQL-based web shop. The leading system here is always a Firebird database. The SQL Editor is an IBExpert tool which simplifies the input of SQL commands. It is used to create and execute SQL queries and view and analyze the results. It is an essential part of IBExpert. As a rule, all work on a database is performed using SQL. The SQL Editor allows you to execute DML and DDL statements, analyze query plans and query performance, move data IBExpert Documentation IBExpert is a professional Integrated Development Environment (IDE) for the development and administration of InterBase and Firebird databases. Context-sensitive help can be started directly from IBExpert using the [F1] key for menu items, windows and SQL keywords. If you are new to IBExpert we recommend first watching our powerpoint

New databases should always be created with dialect 3, which is more powerful in a number of respects. Dialect 1 is a compatibility dialect, to be used only for legacy databases that were first created under InterBase ® 5.6 or earlier. One of the differences between the two is that dialect 1 has no native 64-bit integer type available.

ISC_remap_file therefore does not work and the lock table could not grow. The SAS team had developed a solution in their edition of the Vulcan code to make the lock table expansible on this platform.
