on-line as PDF books. 1.2.1. Language Reference Updates The Data Definition Guide, covering the creation and maintenance of metadata for databases, was “good enough” for several years: the data definition subsets in Firebird’s language implementation are: • Dynamic SQL (DSQL) • Procedural SQL (PSQL) • Embedded SQL (ESQL) • Interactive SQL (ISQL) Dynamic SQL is the major part of the language which corresponds through the public Firebird API and processed by the database engine.

subsets in Firebird’s language implementation are: • Dynamic SQL (DSQL) • Procedural SQL (PSQL) • Embedded SQL (ESQL) • Interactive SQL (ISQL) Dynamic SQL is the major part of the language which corresponds through the public Firebird API and processed by the database engine. Procedural SQL augments Dynamic SQL to allow compound statements containing local variables, assignments, conditions, loops and stored modules (procedures and triggers) only, but in more recent releases they were surfaced in Dynamic SQL as well (see EXECUTE BLOCK). Embedded SQL defines the DSQL subset supported by Firebird gpre

Teilmengen in Firebirds Sprachimplementation sind: • Dynamic SQL (DSQL) • Procedural SQL (PSQL) • Embedded SQL (ESQL) • Interactive SQL (ISQL) Dynamic SQL macht den Hauptteil der Sprache aus, der in Abschnitt Anwendungen über die Firebird API durch die Datenbank verarbeitet werden. Procedural SQL erweitert Dynamic SQL, um zusammengesetzte Anweisungen zu ermöglichen, die lokale Variablen, Zuweisungen, Bedingungen gespeicherten Modulen (Prozeduren und Trigger) verfügbar, aber in neueren Versionen wurden sie auch in Dynamic SQL aufgetaucht (siehe EXECUTE BLOCK). Embedded SQL definiert die DSQL-Untermenge, die von Firebird

forums where the developers hang out. Much hex dumping of database files was undertaken in the creation of this document, but no Firebird databases were harmed during this process.

a stored procedure or trigger, its value is undefined and its state is NULL from the moment of creation until some value is assigned to it. The same is true for output parameters in stored procedures when a unique index is created the table may not contain any NULLs or duplicate values, or the creation will fail. Once the index is in place, insertion of NULLs or duplicate values is no longer possible 'Amst%' ) ...will reject NULL input in Firebird 1.5, but let it pass in Firebird 2. Existing database creation scripts will have to be carefully examined before being used under Firebird 2. If a domain or column
