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 modes: as an interactive session; directly 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 SNAPSHOT isolation, with a lock resolution set to WAIT. Since the Firebird isql utility accepts DDL, DML and other commands, transactions are handled accordingly, in the following ways: • DDL statements

............................................................................................... 3 DML .................................................................................................. perform direct table operations In former versions, a naturally updatable view with triggers passed the DML operation to the underlying table and executed the triggers as well. The result was that, if you followed 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

GENERATOR name; Операторы DML (Data Manipulation Language — язык манипуляции данными) в клиентском SQL: SELECT GEN_ID( GeneratorName, increment ) FROM RDB$DATABASE; Операторы DML в PSQL (Procedural CREATE SEQUENCE name; ALTER SEQUENCE name RESTART WITH value; DROP SEQUENCE name; А для операторов DML: SELECT NEXT VALUE FOR SequenceName FROM RDB$DATABASE; intvar = NEXT VALUE FOR SequenceName; Глава например, в скрипте для создания базы данных. Аналогично CREATE GENERATOR, это оператор DDL (не DML). Предпочтительный синтаксис для СУБД Firebird 2 и старше: ALTER SEQUENCE SequenceName RESTART WITH

name TO value; DROP GENERATOR name; DML (Data Manipulation Language) statements in client SQL: SELECT GEN_ID( GeneratorName, increment ) FROM RDB$DATABASE; DML statements in PSQL (Procedural SQL, available equivalents: CREATE SEQUENCE name; ALTER SEQUENCE name RESTART WITH value; DROP SEQUENCE name; And for the DML statements: SELECT NEXT VALUE FOR SequenceName FROM RDB$DATABASE; intvar = NEXT VALUE FOR SequenceName; created it) in e.g. a script to create the database. Just like CREATE GENERATOR, this is a DDL (not DML) statement. Preferred syntax for Firebird 2 and up: ALTER SEQUENCE SequenceName RESTART WITH NewValue;

Genau wie CREATE GENERATOR ist dies ein DDL- und kein DML-Befehl. Für Firebird 2 und höher bevorzugte Syntax: ALTER SEQUENCE SequenceName RESTART WITH NewValue;
