Guide to SQL: TutorialThe HCL OneDB™ Guide to SQL: Tutorial shows how to use basic and advanced structured query language (SQL) to access and manipulate the data in your databases. It discusses the data manipulation language (DML) statements as well as triggers and stored procedure language (SPL) routines, which DML statements often use.

Object modes and violation detection

The object modes and violation detection features of the database can help you monitor data integrity. These features are particularly powerful when they are combined during schema changes or when insert, delete, and update operations are performed on large volumes of data over short periods.

Database objects, within the context of a discussion of the object modes feature, are constraints, indexes, and triggers, and each of them have different modes. Do not confuse database objects that are relevant to the object modes feature with generic database objects. Generic database objects are things like tables and synonyms.
