Firebird database. Some SET commands can be incorporated in DDL scripts to perform batch executions within isql. It also accepts DDL, DML and console commands. The isql utility can be used in three error -m2 merge diagnostic -n(oautocommit) no autocommit DDL (set autoddl off) -nod(btriggers) do not run database triggers -now(arnings) Switches 7 When the server provides line and column information, users can see the exact line of the DML in the script that caused the problem. When the server only indicates failure, users can view the

SQL Migration Issues DDL Views made updatable via triggers no longer perform direct table operations In former versions, a naturally updatable view with triggers passed the DML operation to the underlying to make it updatable, in that a DML request has to be defined on the view to make the operation on the underlying table happen, viz. 1. if the view's triggers define a DML operation on the underlying table

для генераторов. Операторы DDL (Data Definition Language — язык определения данных): CREATE GENERATOR name; SET GENERATOR name TO value; DROP GENERATOR name; Операторы DML (Data Manipulation Language данными) в клиентском SQL: SELECT GEN_ID( GeneratorName, increment ) FROM RDB$DATABASE; Операторы DML в PSQL (Procedural SQL — процедурный SQL — расширение языка, используемое в хранимых процедурах синтаксис, существует рекомендуемый DDL-эквивалент для СУБД Firebird 2: CREATE SEQUENCE name; ALTER SEQUENCE name RESTART WITH value; DROP SEQUENCE name; А для операторов DML: SELECT NEXT VALUE FOR SequenceName

the section Use of generator statements. DDL (Data Definition Language) statements: CREATE GENERATOR name; SET GENERATOR name TO value; DROP GENERATOR name; DML (Data Manipulation Language) statements statements in client SQL: SELECT GEN_ID( GeneratorName, increment ) FROM RDB$DATABASE; DML statements in PSQL (Procedural SQL, available in stored procedures and triggers): intvar = GEN_ID( GeneratorName, increment in Firebird 2, these are the recommended DDL equivalents: CREATE SEQUENCE name; ALTER SEQUENCE name RESTART WITH value; DROP SEQUENCE name; And for the DML statements: SELECT NEXT VALUE FOR SequenceName

Verwendung der Generator-Befehle beschrieben. DDL (Data Definition Language) — Befehle: CREATE GENERATOR name; SET GENERATOR name TO value; DROP GENERATOR name; DML (Data Manipulation Language) Befehle in in Client-seitigem SQL: SELECT GEN_ID( GeneratorName, increment ) FROM RDB$DATABASE; DML Anweisungen in PSQL (Procedural SQL, verfügbar in Stored Procedures und Triggern): intvar = GEN_ID( GeneratorName für Firebird 2 bevorzugten Äquivalente der DDL-Befehle: CREATE SEQUENCE name; ALTER SEQUENCE name RESTART WITH value; DROP SEQUENCE name; Und für die DML-Befehle: SELECT NEXT VALUE FOR SequenceName
